Trepanel XL® Walnut brings impact to your interior with its impressive 3-metre length and standard Trepanel® slat width, ideal for high ceilings and expansive feature walls. Designed to blend effortlessly, it delivers a sleek, continuous wood slat aesthetic throughout your space. Made using FSC-certified MDF, each wood slat reflects a commitment to responsible materials without compromising on quality. The lightweight construction makes handling and cutting straightforward, allowing for solo installation, though a team of two makes things easier! These wood slat panels are backed with a durable acoustic felt that helps soften noise when installed following the Trepanel® Guide. The slats themselves are finished with a real wood veneer, showcasing authentic grain detail, rich colour variation, and a warm, dark brown walnut wood shade that looks natural from every angle. 

Fixing Guide

To fix Trepanel® we recommend using either black matt coated 38mm screws or Mapei Super Grip Panel Adhesive. One panel requires 21 screws or one tube of adhesive.

The wood veneer is a natural material, and each piece of veneer is unique in terms of wood's natural characteristics, that being texture, colour variation and grain. It also may undergo changes over time when exposed to light.

Please note: We do not recommend use in areas close to a heat source, e.g. a hob or fireplace, or where they will come into direct contact with water.

We recommend regular cleaning with a duster or soft brush to gently remove dust and debris, and avoid harsh brushes and scratchy materials.

Do NOT use any type of wood or furniture polish, as it can damage the veneer. Our panels are fully finished, so no need for additional maintenance or oiling.

Periodic use of vacuums with a soft attachment can easily remove dust from the felt back.

For more stubborn stains, use a damp cloth (not wet). If spills occur, use a clean, absorbent cloth to dry immediately.

Avoid excess moisture with Trepanel® as the felt back should not come into contact with liquids.
