What Are Trepanel Wall Panels?

Trepanel is Walls and Floors' own brand of wall panelling, designed to cover every room in your home from bathroom to living room in one cohesive range. The collection includes Trepanel Aqua for fully waterproof bathroom and shower use, Trepanel Style for decorative acoustic slat panels on feature walls and media walls, and Trepanel Flex for curved surfaces and columns. Each range uses different core materials suited to its environment, so you get the right panel for the right job rather than a one-size-fits-all product.

What are the key benefits of Trepanel panels?

Trepanel panels are an easy way to add warmth, texture, and depth to your walls. They are simple to install, improve the look of any room, and help create a stylish, contemporary interior with minimal maintenance.

How To Choose The Best Trepanel Wall Panels For Your Room Needs

Start with where the panels are going. For bathrooms, shower enclosures, or wet rooms, Trepanel Aqua is the one you want as it is fully waterproof and built for direct moisture contact. For living rooms, bedrooms, and media walls where you want texture, warmth, and acoustic benefits, Trepanel Style acoustic slat panels are the go-to. For curved walls, alcoves, or bar areas, Trepanel Flex bends without cracking. Once you have the right range, pick your finish based on the room colour scheme. Smoked oak and natural wood effects suit warm interiors, darker finishes work well on media walls, and lighter tones make smaller rooms feel bigger.

Which Trepanel Range Is Right For Me — Aqua, Style, Or Flex?

Trepanel Aqua is for wet areas like bathrooms and shower walls. Trepanel Style is for dry rooms where you want a decorative acoustic slat finish on feature walls, TV walls, or behind a bed. Trepanel Flex is specifically for curved surfaces where a rigid panel simply will not bend into place. If you are not sure which one fits your project, the room type tells you everything you need to know.

Is Trepanel Suitable For Bathrooms And Shower Areas?

Trepanel Aqua yes, Trepanel Style no. The acoustic slat panels in the Style range are wood-veneered MDF and are not waterproof. They will warp and swell if used in a wet room or shower enclosure. Always use Trepanel Aqua for any area that sees direct water, steam, or high humidity. For a bathroom feature wall outside the shower zone where moisture is indirect, check the specific product page before fitting.

Can Trepanel Panels Be Used Near A Radiator Or Heat Source?

Keep Trepanel acoustic slat panels away from direct heat sources like radiators, fireplaces, and underfloor heating vents. The wood veneer can warp or discolour when exposed to sustained direct heat. Leave at least 300mm clearance from any heat source as a general rule. Trepanel Aqua panels handle bathroom steam and humidity but are not designed for direct heat either.

Do Trepanel Acoustic Panels Actually Reduce Noise?

Yes, noticeably. The slat design with a felt or acoustic backing absorbs sound rather than bouncing it around the room. You will not soundproof a room completely but you will reduce echo and reverberation, which makes a real difference in open-plan living areas, home offices, and media rooms. It is one of the main reasons people choose Trepanel Style over plain painted walls.

How Many Trepanel Panels Do I Need?

A standard Trepanel panel covers 1.44 square metres. Measure the total height and width of your wall, multiply to get the square meterage, then divide by 1.44 to get the number of panels. Add 10% on top for cuts and waste, and 15% if your wall has sockets, doors, or alcoves to work around. Buy everything in one order so all panels come from the same production batch and the wood grain matches across the wall.

Can Trepanel Be Fitted Over Existing Tiles Or Walls?

Yes. Trepanel Aqua can go directly over clean, flat, well-bonded existing tiles using a suitable grab adhesive. For acoustic slat panels in dry rooms, a flat plastered or painted wall is the ideal base. Fill any large dips or holes before fitting. The flatter the surface underneath, the better the finished result looks, especially on longer slat panels where any unevenness becomes visible along the run.

What Adhesive Or Fixings Should I Use For Trepanel?

For Trepanel Aqua waterproof panels, use a solvent-free grab adhesive on bare walls and a silicone-based adhesive on existing tiles. For Trepanel Style acoustic slat panels, black matt 38mm screws directly into the wall work well and give a clean finish that blends into the dark slat backing. Mapei Super Grip Panel Adhesive is a widely recommended option for bonding the slats in place. Use whatever method suits your wall type and whether you want the fixing to be visible or hidden.

Do I Need To Prepare The Wall Before Fitting Trepanel?

Yes. The wall needs to be clean, dry, and flat. For bathroom installations with Trepanel Aqua, make sure plasterboard is primed and sealed before fitting as bare board absorbs moisture over time. For acoustic slat panels, fill any holes or cracks and sand down any raised areas first. A well-prepared wall takes about 20 minutes to sort and saves hours of fixing problems after the panels are up.

What Tools Do I Need To Cut Trepanel Panels?

A fine-tooth saw handles most straight cuts cleanly. For cutting around sockets, use a jigsaw with a fine blade. Drill pilot holes first before any socket cutouts to avoid cracking or splintering the panel face. A tape measure, pencil, spirit level, and caulking gun for adhesive and silicone complete the basic kit. No specialist tools are needed beyond what most DIYers already have.

Are Trims, Joining Pieces, And End Caps Included?

No, they are sold separately. You will need end caps for exposed panel edges, joining pieces where two panels meet on the same wall run, and corner profiles for internal and external corners. Order these at the same time as your panels so everything arrives together and matches in finish. Always check the trim profiles are compatible with the specific Trepanel range and thickness you have chosen.

Can I Hang Items On Trepanel Acoustic Slat Panels?

Not directly into the slats themselves. The MDF slats are not load-bearing enough to hold shelves, TVs, or heavy artwork on their own. Anchor brackets and fixings directly into the studwork or masonry wall behind the panels instead. For lighter items like small picture frames, use appropriate cavity fixings that pass through the panel and into the plasterboard behind.

What colours are available in Trepanel panels?

Our Trepanel panels are available in a wide range of colours, including natural wood tones, black, dark shades, grey, light tones, beige, cream, ivory, white, blue, oak, and green.

What materials are Trepanel panels available in?

Trepanel panels are made from wood and felt, combining a natural timber finish with acoustic felt backing for a stylish appearance and improved sound absorption.

How Do I Clean Trepanel Panels?

For Trepanel Aqua bathroom panels, warm soapy water and a soft cloth is all you need. For Trepanel Style acoustic slat panels, vacuum gently using a soft brush attachment to remove dust from between the slats. Never use furniture polish, wax, or wet cloths on the wood veneer as it lifts the finish. Avoid bleach, abrasive sprays, or anything acidic on any Trepanel range.

How Do I Maintain The Wood Veneer Finish In A Humid Room?

Keep Trepanel Style panels in well-ventilated rooms only. Run an extractor fan in any room where steam or condensation builds up. Never wipe the veneer with a wet cloth, and avoid placing them directly adjacent to a shower enclosure unless a waterproof barrier separates the two zones. The veneer is a natural material and reacts to moisture just like any other real wood surface would.

What Should I Do If A Trepanel Panel Becomes Loose Or Damaged?

A loose panel means the adhesive bond has failed or the fixing screws have worked loose. Press it back firmly and add fresh adhesive or additional screws as needed. For a scratched or damaged slat, individual slats on some acoustic panel systems can be replaced rather than the whole board. Keep one spare panel from your original order for exactly this reason, stored flat and away from direct sunlight so the wood tone stays consistent.

Can Trepanel Panels Be Removed Or Replaced Later?

Yes. Panels fixed with screws are the easiest to remove cleanly. Adhesive-bonded panels will require a heat gun and a scraper, and some surface damage to the wall underneath is likely depending on how long they have been fitted. If you think you might want to redecorate in a few years, fixing with screws rather than adhesive makes the whole process much simpler when the time comes.
