Features & Benefits
Features & Benefits
It bends, because there is nothing rigid inside it. No MDF, no hardwood backer, no core of any kind — just real wood veneer laminated straight onto 9mm acoustic felt. That is what lets a panel follow a curved wall, a column, a cove or the sweep of a stairwell as it comes, with no kerfing, no steaming and no relief cuts. Work from one end and let the panel take the shape of the wall.
About three pounds a panel. A full eight-foot panel weighs roughly 3 lbs and a box of five runs about 15 lbs. You can carry a box up a flight of stairs in one hand, hold a panel flat against the wall with one arm and fix it with the other. Most single walls are a one-person afternoon.
It barely takes the room. The whole panel measures 9mm — about the thickness of a pencil lying on its side. Shallow enough for ceilings, door reveals and rooms where a deeper panel would read as bulk instead of texture.
Real wood veneer, not a printed film. Every panel carries the grain of the log it came from, so no two are identical and a run reads as timber rather than as a repeat. Ten finishes across oak, walnut and maple, each paired with a felt colour.
59″ of wall in one box. Five panels, 11.80″ each — the widest coverage per box we sell. Fewer boxes on the order and fewer seams to line up on the wall.
It comes down again. Fixed with screws, so it unfixes. Back the screws out, lift the panels down and fill the holes — they sit in the grooves, so they are small.
Materials & Construction
Materials & Construction
The face. Real wood veneer, laminated directly onto the felt with nothing between the two. Ten finishes across oak, walnut and maple, each paired with a felt colour. Felt colour matters more than it sounds — it is what you see in every groove, so it sets how much contrast the slat rhythm carries.
The backing. 9mm acoustic felt made from post-consumer recycled PET, bottles diverted from waste and spun into felt. The felt is what takes the hard edge off a room with a lot of bare surfaces.
The grooves. V-grooves are CNC-cut about three quarters of the way through the felt between each slat face. The last quarter stays intact and does the structural work: it holds the panel together and it is what lets the panel flex instead of snapping.
The measurements. Each slat face is 1.20″ wide and each groove 0.49″, so the rhythm repeats every 1.69″. A panel carries seven slat faces across 11.80″, 9mm thick in total.
The edges. Each end of a panel carries half a v-groove. Butt two panels together and the two halves close into one full groove, identical to the six inside a panel — no lip, no overlap and nothing to align. It is also why a panel covers its full 11.80″ once installed, with nothing lost to a lap.
Sizing & Coverage
Sizing & Coverage
| Panel height | Width per box | Coverage per box |
|---|---|---|
| 94.49″2400mm | 59″ 1499mm | 38.71 sq ft |
| 106″2693mm | 59″ 1499mm | 43.43 sq ft |
| 118.11″3000mm | 59″ 1499mm | 48.39 sq ft |
Only the height changes — every box is 59″ wide. To work out how many you need, divide your wall width in inches by 59 and round up: a 10-foot wall (120″) takes three boxes. Each panel carries half a v-groove at each end, so panels butt together and every 300mm panel covers the full 300mm of wall — nothing is lost to an overlap.
Installation & Care
Installation & Care
Before you start. Work out your box count first: each box covers 59″ of wall width, so divide your wall width in inches by 59 and round up — a ten-foot wall takes three boxes. Order it all at once so every panel comes from the same production run; veneer varies batch to batch.
Mounting. Panels fix straight to the wall with screws or construction adhesive, onto drywall or into studs, with no battens or subframe to build first. Use #6 or #8 wood screws 1.5 to 2 inches long, driven through the felt in a groove rather than through a slat face. Trim head screws are worth buying for this — the head is much smaller, so it seats down into the v-groove and all but disappears. Start at one end of the run and work across in the same direction.
Curves. The panel follows a gentle curve as it comes. Fix one end first, then work along the curve fixing as you go and letting the panel take the shape of the wall — do not flatten it out and try to bend it afterwards.
Butting panels. Push each panel up against the last one. The half-groove on each end closes into a full groove, so keep the panels tight rather than leaving a gap to match the others — the spacing takes care of itself.
Cutting. A fine-tooth blade through the veneer face and a sharp knife through the felt. Cut along a groove wherever you can and the join reads as another groove. For height, cut from the bottom so the factory edge stays at eye level.
Care. Dust the veneer with a dry or barely damp cloth, following the grain, and vacuum the grooves on a low setting with a soft brush head. Skip solvents, wax and steam. Indoor use only — not for bathrooms with a shower, saunas, or anywhere outdoors.
ULTRALIGHT. Real wood on a felt backbone.
What Makes It Bend
The felt is not just backing — it is the structure. That is what lets the panel follow a curve, keeps it light enough to handle alone, and holds the slat rhythm even across a full wall.
Follows the Curve
No MDF, no hardwood backer, no rigid core — so the panel bends to a curved wall, a column or a cove without kerfing, steaming or relief cuts. Work from one end and let it take the shape of the wall.
Cut, Not Assembled
The dark line between each slat is the acoustic felt — and it is also the back of the panel. Every groove is CNC-cut into that felt at the same width and spacing, so the rhythm holds across a whole wall. No core, no backer, nothing glued in behind.
Five Panels to a Box
59″ of wall width in a single box — the widest coverage per box in the range. Fewer boxes on the order, fewer seams to line up on the wall.
Light Enough to Install Solo
Light enough to hold flat against the wall with one arm while you fix it with the other. No helper, no trestles, no waiting for someone to be free on a Saturday.

FAQ
What is an ULTRALIGHT acoustic slat panel?
ULTRALIGHT is a flexible acoustic wood slat wall panel. Real wood veneer is laminated straight onto 9mm recycled acoustic felt, and v-grooves are cut through the felt between each slat face to create the slat rhythm. There is no MDF, no hardwood backer and no rigid core of any kind, which is what makes it the lightest and most flexible panel Slats.co makes.
Each panel is 11.80″ wide and carries seven slat faces. Five panels come in a box and cover 59″ of wall width.
How thick are ULTRALIGHT panels?
ULTRALIGHT panels are 9mm thick in total — about 0.35 of an inch. That is the veneer face and the acoustic felt together, because there is no core between them.
It is the shallowest panel Slats.co sells, which makes it workable on ceilings, in door reveals and anywhere a deeper panel would read as bulk rather than texture.
Do ULTRALIGHT panels have an MDF core?
No. ULTRALIGHT has no MDF, no particle board, no plywood and no hardwood backer — there is no core at all. The wood veneer is laminated directly onto 9mm recycled acoustic felt.
That is the reason the panel is light enough to handle alone and flexible enough to follow a curve. Slats.co panels with a hardwood core, such as TrueWood and the Solid line, are built differently and suit different jobs.
Can ULTRALIGHT panels bend around a curved wall?
Yes. Because there is no rigid core, an ULTRALIGHT panel follows a gentle curve as it comes — no kerfing, no steaming and no relief cuts.
It works on curved walls, columns, coves, bulkheads and the sweep of a stairwell. Fix from one end and let the panel take the shape of the wall rather than trying to flatten it first.
How much does a box of ULTRALIGHT panels weigh?
A box of five ULTRALIGHT panels weighs about 15 lbs at 94.49″, 20 lbs at 106″ and 25 lbs at 118.11″.
That is light enough to carry up a flight of stairs and to hold a panel flat against the wall while you fix it, without a second pair of hands.
How many panels are in a box of ULTRALIGHT?
Five panels. Each panel is 11.80″ wide, so a box covers 59.00″ of wall width — the widest coverage per box Slats.co sells.
By height that works out to 38.71 sq ft at 94.49″, 43.43 sq ft at 106″ and 48.39 sq ft at 118.11″.
How wide is one ULTRALIGHT panel?
Each ULTRALIGHT panel is 11.80″ wide — 300mm. That is seven slat faces at 1.20″ each, separated by v-grooves of 0.49″.
Because each end of the panel carries half a groove, the panel covers the full 11.80″ once installed. There is no lap or overlap to subtract.
How many slats does an ULTRALIGHT panel have?
Seven slat faces per panel, with six full v-grooves between them and half a groove at each end.
Each slat face measures 1.20″ across and each groove 0.49″, so the slat rhythm repeats every 1.69″ along the wall.
How do ULTRALIGHT panels join together?
They butt straight into each other. Each end of an ULTRALIGHT panel carries half a v-groove, so when two panels meet the two halves close into one full groove identical to the six inside a panel.
There is no lip, no overlap and nothing to align. Push the next panel up against the last one and the seam disappears into the rhythm of the grooves.
How many boxes of ULTRALIGHT do I need?
Measure the width of your wall in inches and divide by 59 — each box covers 59.00″ of wall width. Round up, because the offcut from the last panel usually finds a use elsewhere on the wall.
A ten-foot wall (120″) takes three boxes. A sixteen-foot wall (192″) takes four. If you are unsure, send us your measurements and we will work it out with you.
How do you install ULTRALIGHT panels?
ULTRALIGHT panels fix to the wall with screws or construction adhesive. Screws go through the felt in a groove rather than through a slat face, so the head sits down in the shadow line instead of on the wood.
Start from one end, check the first panel is plumb, then butt each following panel up against the last. Most walls are a one-person job at this weight.
Do ULTRALIGHT panels need a batten or frame behind them?
No. ULTRALIGHT fixes straight to the wall surface — drywall, plaster or timber — with screws or construction adhesive. No battens, no furring strips and no subframe.
That is part of why the panel only takes 9mm off the room. On a curved or uneven surface, fixing straight to the wall also lets the panel follow the shape rather than bridging it.
Can ULTRALIGHT panels be installed on a ceiling?
Yes. At 9mm thick and about 15 lbs a box, ULTRALIGHT is the easiest Slats.co panel to take overhead.
Use construction adhesive together with screws on a ceiling rather than adhesive alone, and support each panel while the adhesive takes. Work along one line so the grooves stay continuous across the span.
Can ULTRALIGHT panels be cut to size?
Yes. Cut the veneer face with a fine-tooth blade and the felt with a sharp knife.
Wherever you can, cut along a groove — the join then reads as another groove instead of a cut edge. For height, cut from the bottom so the factory edge stays at eye level.
How do I cut ULTRALIGHT around outlets and light switches?
Mark the opening on the face of the panel, then cut the veneer with a sharp knife or a fine-tooth blade and peel the felt back behind it.
Because the felt is only 9mm and has no rigid core, it cuts cleanly without chipping or blowing out the back. A cover plate sits over the edge and hides the cut.
Can I mount a TV or shelves on ULTRALIGHT panels?
Yes, but fix into the wall behind, never into the panel. ULTRALIGHT is veneer on felt with no rigid core, so it carries no structural load at all.
Locate your studs before you panel, mark them, then run your bracket fixings through the panel and into the stud. Bring the bracket bolts through a groove where you can.
Do ULTRALIGHT panels absorb sound?
The 9mm recycled felt backing softens echo and reverb in a room, and the v-grooves expose more felt surface to work with. In practice people notice a room sounding warmer and less live, particularly in spaces with hard floors and bare walls.
Slats.co does not publish an NRC rating for ULTRALIGHT, so we will not quote one. If your project needs a certified acoustic figure, tell us and we will point you at what we can and cannot document.
Are ULTRALIGHT panels fire-rated?
Our panels are not fire rated. If a fire rating is required for your project, check with your contractor or your local building code before ordering.
What sizes do ULTRALIGHT panels come in?
Three heights for the standard slat: 94.49″ for eight-foot walls, 106″ for nine-foot walls and 118.11″ for ten-foot walls. All three are 11.80″ wide per panel, five panels to a box.
There is also a 47″ tile size sold separately for smaller areas and feature bands.
What finishes do ULTRALIGHT panels come in?
Ten, across oak, walnut and maple, each paired with a felt colour: White Oak with black, grey or oatmeal felt; Walnut with black, grey or brown felt; Grey Oak, Black Oak and Dark Smoke Oak with black felt; and Maple with beige felt.
Felt colour matters more than it sounds — it is the colour you see in every groove, so it sets how much contrast the slat rhythm carries.
Is ULTRALIGHT real wood?
Yes. The face is real wood veneer, not a printed film or a photographic laminate.
Because it is real wood, the grain varies from panel to panel and from batch to batch. That is worth knowing if you are matching an order placed months apart — order the whole wall together where you can.
How much does shipping cost on ULTRALIGHT panels?
Shipping is free to the contiguous U.S. on most ULTRALIGHT orders. The exceptions are samples, and 118.11″ panels ordered in quantities of 1 to 3 boxes, where shipping is calculated at checkout.
Order 4 or more boxes of 118.11″ panels and shipping is free. The 118.11″ boxes are long enough to move by freight rather than parcel, which is why the carrier rate shows up on smaller orders.
How long do ULTRALIGHT panels take to arrive?
Most ULTRALIGHT orders leave the warehouse within one to two business days, with delivery to the contiguous U.S. typically inside a week.
Freight shipments of 118.11″ panels take longer and are booked with a delivery appointment. The delivery estimate on the product page reflects the current lead time for the size and finish you are looking at.
Can ULTRALIGHT panels be used in a bathroom or outdoors?
ULTRALIGHT is for indoor use only. It is not suitable for outdoors, saunas, or bathrooms with a shower or bath in the same room.
A powder room with good ventilation and no shower is usually fine. Wood veneer and felt both take on moisture, and neither recovers well once they have.
How do I clean ULTRALIGHT panels?
Dust the veneer with a dry or barely damp cloth, following the grain. Vacuum the felt in the grooves on a low setting with a soft brush head.
No solvents, no wax, no polish and no steam. If something is spilled on the felt, blot it up rather than wiping across.
Can ULTRALIGHT panels be painted or stained?
We do not recommend it. The face is a thin real wood veneer, and stain lifts unevenly while paint fills the grooves and flattens the slat rhythm that the panel is there for.
If you want a painted finish, the Paint-Ready Fluted line is made for exactly that — it ships pre-primed white and is designed to be painted in your own colour.
Will ULTRALIGHT panels expand or contract?
No meaningful movement. There is no solid timber and no MDF in the panel, so there is nothing to swell or shrink with humidity the way a cored panel can.
You do not need expansion gaps at the seams. Butt the panels tight and they stay tight.
Can I take ULTRALIGHT panels with me if I move?
Yes, if they were fixed with screws. Back the screws out, lift the panels down and patch the holes — they sit in the grooves, so they are small and easy to fill.
Panels fixed with construction adhesive are not intended to come off cleanly. If you are renting or expect to move, use screws.
Are ULTRALIGHT panels renter-friendly?
They are the most renter-friendly panel Slats.co makes. They are light enough to handle alone, they fix with screws rather than anything permanent, and they come down and travel with you.
Check your tenancy agreement on wall fixings first. Screw holes land in the grooves, so patching is a small job.
Are ULTRALIGHT panels eco-friendly?
The 9mm felt backing is made from post-consumer recycled PET — plastic bottles diverted from waste and spun into felt. The panels are independently tested to meet low-VOC standards.
Slats.co also plants a tree for every panel sold. And because ULTRALIGHT uses veneer rather than solid timber, a given log covers far more wall.
Does Slats.co offer ULTRALIGHT samples?
Yes. Individual ULTRALIGHT samples are $3.99 each, and the full sample kit is $30.
Worth doing. Veneer colour and felt colour both shift under different light, and a sample on your own wall answers that in a way a screen cannot.
Where is Slats.co based?
Slats.co is a Southern California company, shipping across the contiguous United States.

Everything about this company is absolutely outstanding! Quality of the bamboo slats was top notch with excellent, consistent coloring of wood across over 21 feet of slats; customer service answering questions was responsive, clear, courteous, and spot on; the shipping was fast and each pair of slat panels was separately boxed and well-protected so there was ZERO damage to the slats; the installation using circular saw, jig saw, and drill was easy, just like YouTube described. I was worried that cutting the slats would cause splintering, but painter's tape prevented that. I shopped around for two months looking at various companies and wood slats. This company stood out for their solid bamboo slats in 1 foot wide panels from California. The company's attention to detail and superb customer service only made the experience so much more satisfying. But the best part was the final result: the slat panels completely transformed a cold, blank wall into a warm backdrop for our art and Frame TV.
Slats.co makes such an amazing product! I cut and installed their wall panels in my home office in one day and it completely transformed my office into a quiet, warm, inviting, and professional workspace. I cannot say enough about this amazing product! Thank you Slats.co!!
Felt backing and the slats itself are good material. I ordered 3 boxes, out of which 1 had stapled slats on felt while other 2 were glued. The staples one became loose at few points and cutting them was difficult as loose pieces came out. I had to glue them back. I believe they updated the process and now glueing them on the felt which is much better. I would recommend getting the glued on panels instead of staples.
Lite version looks good but I wish they made regular version for long lengths too. Overall, I am happy how they look on the wall - Get the truewood!
VERY happy with this purchase! Excellent product quality, easy installation, and superb customer service! The wood has dimension to it and looks great, especially in a room with a lot of natural light. Highly recommend!
We had a great paper white room hat needed a feature wall to make it pop. So after a ton of research, we figured we needed the Ultralight Walnut version, and we are so glad we did. We are so addicted to the outcome that we have identified two more rooms/walls to do the same, and we ordered 5 more boxes!
Overall I am happy with the new slats. The veneer is extremely thin and I had to be careful not to chip it simply handling them during cutting and install. They did cut well on my table saw. They look great installed, but I'm not expecting years of durability. If the veneer was even a 16th of an inch, I'd give them 5 stars.
These were just what I was imagining my plain-walled office space needed. Having virtual meetings with an empty white space behind me was getting old and I didn't want to just hang shelves. Enter Slats and I now have the visual interest I needed (with the help of a couple framed pictures). Perfect in every way!
I had a wall that was a little boring and the room on the other side, sometimes complained about noise. It was easy to cover the entire wall with these, and I just used a box cutter, ruler, and finishing nails.
They look beautiful and work well at damping sound. Shipping was quick, and the product was nicely packaged.
Fantastic product!
Beautiful real solid Walnut hardwood. Surface feels smooth and solid. Natural minor warping, but not a problem after glued and mounted to wall.
Super nice! Just what I was hoping for and they look really classy. The black felt and gray oak is a great combo. These are perfect for our .5" thick trim.
Pleased with the quality and the ease of installation with the product.
Slats has been very helpful with a miss order on my part and resolved my order.
It’s been installed and looks great.
Dark Smoke Oak TrueWood Lite 3-Sided Veneer Acoustic Slat Panel
Very easy to put up and looks amazing
Beautiful wood ! Easy to install only thing that i dislike is the slats come loose. Needsmore staples and maybe glue to hold the slats on . I worked around that prby gluing and tapping the slats that came off.
Could not be happier with American Walnut TrueWood Lite 3-Sided Veneer Acoustic Slat Panel. The order arrived within days. It is a high quality product. The slates went up easily and added a rich look to an otherwise plain room. Will definitely order again for future projects!
American Walnut TrueWood Lite 3-Sided Veneer Acoustic Slat Panel is a great product. Easy install with construction adhesive. Used my trac saw to cut the slats and it worked great both horizontal and vertical. Staining was easy due to the three-sided veneer. Matches perfectly to my black walnut dining table. Slatsco offered great customer service. Can't wait to install some of their other great products.
I absolutely love these slats! The quality is fantastic, and they look beautiful once installed. They’re also surprisingly easy to work with — easy to cut to size, and you can attach them to the wall using adhesive or nails.
One tip: be a little careful when taking them out of the box and handling them before installation, as you don’t want to accidentally bend them.
What really stood out to me was the customer service. Truly A+++! They are incredibly kind, genuine, helpful, and very fast to respond. You can really tell there are real people behind this company who care about their customers.
I also love supporting a small, family-owned business, especially when both the product and service are this good. I would absolutely purchase from them again and highly recommend them to anyone considering these slats!
Great quality product, uniform and clean all around.
