PROSAUNAS Thermo-Aspen 2X6 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $11.89 through $118.92The bench wood we have the most opinions about. Thermally modified aspen, milled wide at 2×6 so a bench or backrest reads as one clean surface. Aspen doesn’t bleed resin, doesn’t splinter, and sits cool under bare skin even when the room is ripping. The thermal modification (heat and steam, nothing else) takes it to a golden brown and stops the expansion that opens gaps over the years. Aspen is the wood we sell more of than any other, season after season. Pair it with thermo-aspen or thermo-spruce walls for the matched look.

It’s the same thermal modification as the rest of our thermo-aspen line: heat and steam, no chemicals, golden-brown color all the way through, no warp, no resin, cool under bare skin. Available up to 10-foot lengths. Sold by the linear foot.

Thermory Thermo-Aspen 2×2 VA
Price range: $3.15 through $31.50
PROSAUNAS Thermo-Aspen 1X4 T&G STS4 Wall Cladding – Sauna Wood
Price range: $4.38 through $43.78A clean, classic sauna wall in the cladding width most builders start with. The 1×4 STS4 in thermo-aspen is a tongue-and-groove board, 0.59″ thick, milled 3.54″ wide for 3.1″ of coverage per row. The thermal modification takes it to a warm golden-brown that runs all the way through, so trimmed ends match the face and nothing reads as patchwork. Knot-free, no resin, stays cool against bare skin. Easy to run floor to ceiling and easy to pair with a contrasting bench or trim. Sold by the linear foot.
PROSAUNAS Thermo-Spruce 2X6 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $5.87 through $58.73Ben sided his own house in thermo-spruce. That tells you something. This is the 2×6 bench board in thermally modified Nordic spruce, 1.02″ thick by 5.51″ wide, and it’s the classic budget build starting point. Rich amber color, tight knots, a rustic look that’s not for everybody but that a lot of people flat-out love. The thermal modification (heat and steam, no chemicals) gives it the same moisture resistance and stability you get in thermo-aspen, at a lower entry price. Strong, rot-resistant, and good for benches and floors. The classic move is thermo-spruce walls with thermo-aspen benches. Sold by the linear foot.
PROSAUNAS Thermo-Aspen Groove-S 1X3 T&G Wall Cladding – Sauna Wood
Price range: $5.98 through $59.84Narrow boards, strong lines, a wall that looks expensive. The Groove-S in thermo-aspen is a precision-milled 1×3 T&G cladding, 0.59″ thick, with a tight shadow groove that turns an ordinary sauna wall into something with real visual snap. At 2.1″ coverage per board, you get a lot of linear rhythm per square foot. The thermo-aspen color, warm golden-brown, runs all the way through, so trimmed ends match the face and nothing reads as patchwork. Knot-free, no resin, stays cool. Pairs well with thicker profiles as a contrast element. Sold by the linear foot.
PROSAUNAS Thermo-Aspen 2X2 VA Outside Corner Trim – Sauna Wood
Price range: $3.15 through $25.23An outside corner with no raw edge showing. The thermo-aspen VA outside corner trim, 1.1″ on both faces, wraps the 90-degree exterior angle where two cladded walls meet and gives you a clean, mitered line in matching wood. Thermally modified aspen, so the golden-brown color runs all the way through, cut ends look the same as the face, and the piece won’t swell or bow in a wet sauna environment. No resin, no splinters. If you have a sauna room with an exterior corner (a bump-out, a partition, a two-room build), this is what goes there. Sold by the linear foot.
PROSAUNAS Hemlock 1/2X4 VG T&G V2E Wall Cladding – Sauna Wood
Price range: $4.00 through $40.07Pale walls, tight joints, almost no smell. This is Hemlock 1/2×4 VG T&G V2E wall cladding: clear A+ grade, 0.44″ thick, 3.49″ of coverage per board, V-joint profile, milled in Canada. If cedar is the sauna your grandfather built, hemlock is the sauna you’d design today. Quiet, bright, modern. It’s the cladding choice for a contemporary build that wants clean pale walls and a room that doesn’t smell like the wood. Ben likes the hemlock look. The honest note: hemlock walls will shift to a slight yellow tint under artificial light over time, more noticeable in rooms without natural light. For the brightest long-term pale look, our thermo-aspen cladding stays truer. Sold by the linear foot.
PROSAUNAS Aspen Groove-S 1X3 T&G Wall Cladding – Sauna Wood
Price range: $5.87 through $58.77Narrow boards, crisp shadow lines, a lot of personality in a small footprint. The Groove-S is a 1×3 tongue-and-groove in natural aspen: 15mm thick, 60mm wide, 47mm of coverage per board, with precision-milled fluted slats that give a wall real visual texture. Aspen means pale, cool, resin-free. This profile means the room looks like a decision was made, not just a box lined with boards. Sold by the linear foot in 1, 5, and 10 ft lengths.
PROSAUNAS Alder 2X4 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $5.24 through $52.36
PROSAUNAS Alder 1X4 T&G STS4 Wall Cladding – Sauna Wood
Price range: $4.00 through $40.03
PROSAUNAS Aspen 2X4 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $6.68 through $66.81
PROSAUNAS Aspen 1X5 T&G STS4 Wall Cladding – Sauna Wood
Price range: $6.68 through $66.81
PROSAUNAS Thermo-Aspen 3X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $11.62 through $92.96Bench legs that don’t need to be babied. The 3×3 thermo-aspen is a glulam engineered bench support, 2.68″ square on both faces, built to carry weight in a wet, hot room for years without moving. Same thermal modification as everything else in our thermo line: heat and steam, no chemicals, golden-brown color that runs all the way through the wood. Strong, stable, and cool to the touch. Order your bench boards and these together and the whole system ships as one delivery. Sold by the linear foot, free samples available.
PROSAUNAS Spruce 1X4 T&G STS4 Wall Cladding – Sauna Wood
Price range: $1.33 through $18.68The most economical real sauna wood we carry, and the traditional one. Natural Nordic Spruce, 1×4 smooth tongue-and-groove, the wood Finland has lined saunas with for generations. Light tone, tight characterful knots, a clean mild scent. It is not thermally modified, so it moves a little more than our thermo woods through the heat-and-cool cycle. We carry it for the budget build and the honest Finnish look. Sold by the linear foot, in lengths up to 14 ft.
PROSAUNAS Hemlock 2X4 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $10.29 through $102.85Thick, pale, and honest about what it is. Hemlock 2×4 VG S4SEE is 1.5″ of clear, knot-free hemlock bench stock, 3.5″ wide, surfaced and eased, milled in Canada. At this thickness the bench edge reads as a real piece of wood, not a veneer. Low resin, even texture, almost no scent. We stock the clear VG grade because it’s the one we’d use. Honest note: hemlock at 1.5″ thick moves more through the heat cycle than thermo-aspen, and over years small gaps can open at the joints. For tight long-term joints, thermo-aspen is a better bet. For a pale, modern bench in clear North American wood, this is a good board. Sold by the linear foot.
PROSAUNAS Hemlock 1X6 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $7.48 through $52.36Six inches of pale, clear hemlock bench board. This is Hemlock 1×6 VG S4SEE: 0.69″ thick, 5.44″ wide, clear A+ grade, straight grain, no knots, almost no scent. Milled in Canada. The wider face means fewer boards on a bench, fewer gaps to manage, and a surface that reads as one clean piece from where you sit. We stock hemlock now because we found a clear grade worth standing behind. The light straw color is the point: it makes a modern, neutral room feel intentional, not default. One note: wide hemlock boards can pick up a mild yellow shift under artificial light over time, more noticeable than on narrower stock. Sold by the linear foot.
PROSAUNAS Hemlock 1X4 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $5.07 through $50.75Pale, clean, and quieter than you’d expect. This is Hemlock 1×4 VG S4SEE bench board: clear A+ grade, 0.69″ thick, 3.5″ wide, straight-grained, knot-free, milled in Canada. Hemlock has a light straw color and almost no scent, which makes it the right choice for anyone sensitive to cedar aroma or building a room with a modern, neutral look. We didn’t carry hemlock for years because we couldn’t find a supplier with clear grade we trusted. We carry this one now. One real note: hemlock can pick up a slight yellow tint under artificial light over time. If the room is well-lit with daylight it reads beautifully. Sold by the linear foot.
PROSAUNAS Western Red Cedar 1X4 STK T&G V2E Wall Cladding – Sauna Wood
Price range: $2.64 through $21.16The knottier option, and honestly the one with more character. This is Western Red Cedar 1×4 tongue-and-groove V2E wall cladding in STK grade, milled in Canada with natural tight knots and a warm reddish tone. At 0.70″ thick with a 2.95″ coverage width, it goes up fast and smells like every sauna movie you’ve seen. STK means you’ll have knots: they’re tight, they’re natural, and they give the room a cabin-honest feel that clear boards don’t. We carry a clear VG grade too if that’s your look. One heads-up: like all untreated cedar, this will move a little through the heat-and-cool cycle over the years. Sold by the linear foot.
PROSAUNAS Western Red Cedar 4X4 S4S Bench, Backrest & Skirting – Sauna Wood
Price range: $88.15 through $176.31The part of the bench nobody photographs but everyone sits on. Western Red Cedar 4×4 S4S is a 3.5″ x 3.5″ structural post, surfaced four sides, milled in Canada. The bench leg. Cedar at this dimension is naturally rot-resistant without any treatment, which matters in a room that runs wet and hot. Available in 3, 4, 5, and 6 ft lengths to match common bench heights. Honest note: cedar posts move more through the heat cycle than steel, so snug your fasteners after the first season. A cedar frame with cedar bench stock means matched wood tones and no species mismatch. Sold by the linear foot.
PROSAUNAS Western Red Cedar 2X4 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $14.82 through $148.27Thick cedar bench boards in clear grade are not easy to find anymore. This is Western Red Cedar 2×4 VG S4SEE: 1.5″ thick, 3.5″ wide, knot-free vertical grain, surfaced and eased, milled in Canada. It’s the bench board for the builder who wants the full cedar package done at a quality level that won’t embarrass the rest of the build. The aroma is the real thing, the grain is clean, and the 1.5″ thickness gives the bench a visual weight that thinner boards don’t. Honest note: at roughly 3x the cost of thermo-aspen, this is a high-cost choice, and thermo wood holds its joints tighter over the years. But if clear cedar 2×4 bench stock is what you’re after, this is it. Sold by the linear foot.
PROSAUNAS Western Red Cedar 2X4 STK S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $4.67 through $37.40Knots and all. Western Red Cedar 2×4 STK S4SEE is the thicker bench board for the builder who wants the weight and depth of a 1.5″ seat without paying clear-grade prices. STK means Select Tight Knot: the knots are natural, tight, and part of the character. At 3.5″ wide and 1.5″ thick, this is a substantial bench board with a real cedar look. The aroma is there, the reddish grain is there, and the lower price point makes a full bench build more realistic. Honest downside: the knots and the STK-grade movement mean these boards gap a bit more than clear VG over the years. Milled in Canada. Sold by the linear foot.
PROSAUNAS Western Red Cedar 1X6 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $14.16 through $113.27Wide benches read differently. A 5.44″ board shows less joint, more wood, and the cedar grain has room to do something. This is Western Red Cedar 1×6 VG S4SEE in clear vertical grain, knot-free A+ grade, milled in Canada. At 0.69″ thick, it’s the wider face of our cedar bench line and it makes a single-board backrest or a bench seat with far fewer pieces to install. We waited to carry cedar until we found a clear grade we’d actually put in our own build. The honest note: cedar runs warmer to the touch than aspen at full heat, and it moves more through the heat-and-cool cycle than thermally modified wood. For the classic cedar look at width, this is the board. Sold by the linear foot.
PROSAUNAS Western Red Cedar 1X4 VG S4SEE Bench, Backrest & Skirting – Sauna Wood
Price range: $7.48 through $74.80For years we steered people away from cedar. Then a clear vertical-grain run came through worth carrying. This is Western Red Cedar 1×4 VG S4SEE bench board, knot-free A+ grade, milled in Canada, 0.69″ thick and 3.5″ wide. It’s the bench face the classic sauna crowd wants: warm reddish tone, smooth texture, and that cedar aroma that hits you when the room heats. We waited because modern cedar quality slipped while prices climbed. We carry it now because this grade is actually worth installing. One honest note: cedar runs warmer to the touch than aspen under real heat. If cool skin contact is the priority, aspen benches with cedar walls is a better combo. Sold by the linear foot.
PROSAUNAS Aspen Grace™ 2X3 T&G Wall Cladding – Sauna Wood
Price range: $4.81 through $48.08You won’t find this profile from most mills. Grace is a wide-grooved designer tongue-and-groove, 27mm thick and 64mm wide, with a 56mm coverage and a shadow reveal that reads architectural rather than just “sauna wall.” It’s aspen, so the tone is pale, the surface is resin-free and smooth, and the room stays bright. We carry Grace because when a customer wants a contemporary room that looks considered, not just lined, this is what gets them there. Sold by the linear foot in lengths from 1 to 10 ft.
PROSAUNAS Aspen 1X4 T&G STS4 Wall Cladding – Sauna Wood
Price range: $4.41 through $44.08The Scandinavian default, and ours too. This is natural aspen tongue-and-groove wall cladding, STS4 profile, milled in Estonia at 15mm thick and 90mm wide with 80mm of coverage per board. Pale, bright, no resin, no splintering, and cool to the touch even when the room is running at full temperature. We sell more aspen than any other wood, year after year, because it works: it reads clean in any lighting, it pairs with every heater finish, and nobody is allergic to it. Sold by the linear foot in lengths from 1 to 10 ft.
PROSAUNAS Aspen 2X2 VA Outside Corner Trim – Sauna Wood
Price range: $3.07 through $24.57Outside corners on a sauna wall are a small detail with a noticeable finish impact. The aspen 2×2 VA outside corner trim wraps the convex corner where two clad surfaces meet on the exterior angle: 28mm on both faces, in pale natural aspen that matches the wall boards. It gives the corner a finished look and protects the raw edge of the cladding at the same time. Sold by the linear foot in 1 and 10 ft lengths at $3.07/lf, milled in Estonia.
PROSAUNAS Aspen 2X2 S4SEE SHP Moulding & Trim – Sauna Wood
Price range: $3.60 through $36.0728mm square, eased edges, four smooth faces. The aspen 2×2 S4SEE moulding is the heavier finishing piece: thicker than the 1×1 at 1.1″ square, with enough visual presence to anchor a ceiling line or a bench-frame transition. Same pale natural aspen as the cladding, so it blends rather than competes. The detail that separates a lined room from a finished room is usually this piece, or its absence. Sold by the linear foot in 1 and 10 ft lengths at $3.60/lf, milled in Estonia.
PROSAUNAS Aspen 1X2 T-Moulding Moulding & Trim – Sauna Wood
Price range: $2.54 through $20.31The T-moulding is the piece most people forget to order until the bench is built and there’s an exposed edge staring back at them. This is the ProSaunas aspen 1×2 T-moulding: 17mm thick, 32mm wide, in pale natural aspen that matches our cladding and bench boards. It covers raw edges cleanly, sits flush where two surfaces meet at a seam, and disappears into the room the way good trim should. Sold by the linear foot in 1 and 10 ft lengths at $2.54/lf, milled in Estonia.
PROSAUNAS Aspen 1X1 S4SEE SHP Moulding & Trim – Sauna Wood
Price range: $2.13 through $17.09Small piece, big finish difference. The aspen 1×1 S4SEE is a 21mm square moulding, surfaced smooth on all four sides with eased edges, and it’s what turns a clad sauna wall from a room with boards on it into a room that looks finished. Cap a horizontal run, cover a ceiling-to-wall seam, hide a gap where wall meets bench frame: this is the piece. Pale aspen, resin-free, cool to the touch. Sold by the linear foot in 1 and 10 ft lengths at $2.13/lf, milled in Estonia.
PROSAUNAS Aspen 1X2 SI Inside Corner Trim – Sauna Wood
Price range: $1.61 through $12.83Inside corners are where most DIY sauna cladding jobs show their work. The aspen 1X2 SI inside corner trim is the piece that covers the raw edges where two clad walls meet at an interior corner: 14mm thick, 30mm wide, in pale natural aspen that matches the wall boards. Simple, clean, and it makes a corner look like it was planned rather than improvised. Sold by the linear foot in 1 and 10 ft lengths at $1.61/lf, milled in Estonia.
PROSAUNAS Aspen 1X2 UK Door Trim – Sauna Wood
Price range: $3.07 through $24.57Every clad sauna room has a door, and the door surround is where the cladding either reads finished or reads unfinished. This is the ProSaunas aspen 1×2 UK door trim: 12mm thick, 42mm wide, in natural aspen that matches the wall boards. It wraps the door opening cleanly and covers the raw edge of the cladding at the reveal. Aspen stays cool, has no resin, and takes paint or a clear finish equally well. Sold by the linear foot in 1 and 10 ft lengths at $3.07/lf, milled in Estonia.
PROSAUNAS Aspen 3X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $11.62 through $92.9668mm square, surfaced smooth on all four sides. The aspen 3×3 S4SEE is a bench board that’s a true square in cross-section: 2.68″ thick and 2.68″ wide. That’s the profile for a chunky, solid-looking bench deck or a structural backrest leg. Aspen, so it’s pale, cool to the touch, and resin-free. The square stock also works as a bench support rail where you want the wood exposed, not hidden. Sold by the linear foot in 1 and 10 ft lengths at $11.62/lf, milled in Estonia.
PROSAUNAS Aspen 2X6 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $11.08 through $110.87Wide bench board, pale aspen, eased edges. The 2×6 S4SEE is 28mm thick and 140mm wide: three boards across a standard 18-inch bench deck and you’re done, with almost no slat gaps breaking up the surface. Aspen stays cool to the touch, never bleeds resin, and shows no splintering. We sell more aspen bench wood than any other species. This is the wide version for a clean, uninterrupted bench surface. Sold by the linear foot in 1 and 10 ft lengths at $11.08/lf, milled in Estonia.
PROSAUNAS Aspen 2X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $4.14 through $41.40Bare skin at 185 degrees, and this board stays comfortable. The 2×3 aspen bench board, surfaced four sides with eased edges, is the narrow bench option: 28mm thick, 65mm wide, smooth and resin-free. It’s the right choice for a backrest, a skirting run, or a bench deck where you want slender gaps and a clean, quiet look. We sell more aspen bench wood than any other species, season after season. Sold by the linear foot in 1 and 10 ft lengths at $4.14/lf. Milled in Estonia.
PROSAUNAS Alder Grace™ 2X3 T&G Wall Cladding – Sauna Wood
Price range: $4.81 through $38.47The wall profile that makes people stop and ask what species that is. Grace is a wide tongue-and-groove with a precision shadow reveal, and in natural alder the warm reddish-brown tone makes those grooves pop. Each board is 2.52" wide with 2.2" net coverage, milled in Estonia to 1.06" thick. Dramatic for a wall, clean for a ceiling, honestly different from the usual sauna paneling. Pairs with any alder bench board for a matched room. Sold by the linear foot in 1 and 8 ft lengths.
PROSAUNAS Alder 2X2 VA Outside Corner Trim – Sauna Wood
Price range: $3.07 through $24.57Outside corners are the exposed edges, which means they’re what people see and touch first. This is the alder VA outside corner trim: 1.1" square (28mm x 28mm), angle-moulded to wrap outside corners cleanly in natural alder. Same warm reddish-brown tone as the rest of the ProSaunas alder family, milled in Estonia, E1 certified. Beefier than the inside corner piece at the same 1.1" section, which makes sense: outside corners take contact. At $3.07 per linear foot it finishes the room where the finish matters most. Sold by the linear foot in 1 and 8 ft lengths.
PROSAUNAS Alder 2X2 S4SEE SHP Moulding & Trim – Sauna Wood
Price range: $3.48 through $34.73The trim piece that pulls a room together. This is the alder 2×2 S4SEE moulding: 1.1" square (28mm x 28mm), surfaced four sides with eased edges, milled in Estonia from natural alder. Use it to cap bench edges, frame out a heater enclosure, or add a furniture-quality line wherever you need one. Warm reddish-brown tone matches the alder bench and cladding family exactly. At $3.48 per linear foot it’s the least glamorous piece in the room, but the room looks noticeably better with it. Sold by the linear foot in 1, 8, 9, and 10 ft lengths.
PROSAUNAS Alder 1X2 SI Inside Corner Trim – Sauna Wood
Price range: $1.36 through $10.90Corners make or break a cladded room. This is the alder SI inside corner trim: 0.55" thick by 1.18" wide (14mm x 30mm), milled in Estonia to close out the inside corners where two cladded walls meet. Without it, the cladding ends look ragged. With it, the room reads furniture-quality. Natural alder, warm reddish-brown, E1 certified, and at $1.36 per linear foot it’s the lowest-cost piece in the alder family. Sold by the linear foot in 1 and 8 ft lengths.
PROSAUNAS Alder 1X2 UK Door Trim – Sauna Wood
Price range: $3.07 through $24.57Every sauna door looks better with this on it. The alder 1×2 UK door trim, 0.47" thick by 1.65" wide (12mm x 42mm), milled in Estonia from natural alder for clean, finished doorway edges. This is the piece that makes the transition from framing to cladding look intentional. Warm reddish-brown alder tone, fine grain, E1 certified. Water-repellent and cool to the touch. It’s a finishing detail, not a structural piece, but a sauna doorway without it reads unfinished. Sold by the linear foot in 1 and 8 ft lengths.
PROSAUNAS Alder 3X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $11.62 through $92.96The leg of the operation. This is the 3×3 glulam alder bench support, 2.68" square, engineered from natural alder for the structural parts of a sauna bench. Not a finish piece: it’s what holds everything up. Same warm reddish-brown alder, same E1 certification, milled in Estonia. At 2.68" x 2.68" (68mm x 68mm), it’s got the cross-section to handle bench loads without flex. Matches the alder bench board family if you want the whole structure in one species. Sold by the linear foot in 1 and 8 ft lengths.
PROSAUNAS Alder 2X6 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $10.68 through $106.85Wide-board alder bench material, and it reads completely differently than the 2×3. At 5.51" wide (140mm), each board is a statement. Same natural alder warmth: reddish-brown, fine grain, a soft honey scent when steam hits it. Milled in Estonia to S4SEE spec, 1.1" thick, eased edges on all four sides. Water-repellent, stays cool under bare skin, E1 certified. If you want a bench or backrest that reads as one clean, warm surface rather than a field of narrow slats, this is your board. Sold by the linear foot in 1, 9, and 10 ft lengths.
PROSAUNAS Alder 2X3 S4SEE SHP Bench, Backrest & Skirting – Sauna Wood
Price range: $4.00 through $40.07Sit on it for five minutes and you’ll understand why Finland has been using alder on benches for a hundred years. This is the 2×3 S4SEE bench board in natural alder, milled in Estonia to 1.1" thick by 2.56" wide, surfaced four sides with eased edges. Warm reddish-brown tone, fine grain, a faint honey scent when the room heats up. Water-repellent and stays cool against bare skin. Good clear cedar now runs nearly three times the price; alder is the honest alternative for a timeless Finnish room. Sold by the linear foot in lengths from 1 to 10 ft.
PROSAUNAS Western Red Cedar 1/2X4 VG T&G V2E Wall Cladding – Sauna Wood
Price range: $6.15 through $79.87For years we steered people away from cedar. Then a clear vertical-grain run came through worth carrying. This is Western Red Cedar 1/2×4 with a V-joint, knot-free A+ grade, milled for sauna walls and ceilings. It’s the wood Americans picture when they picture a sauna: the warm reddish tone, the aroma that shows up the second the room heats. We carry it for the look-and-smell buyer who wants the classic done right, and we’ll tell you straight where thermo wood holds up better. Sold by the linear foot.
