Trepanel XL® Ash Grey is a bold and versatile design solution for achieving the ever-popular wood slat look, perfect for homes with tall ceilings or large feature walls. With its impressive 3-metre length and standard Trepanel® slat width, it delivers a smooth, continuous appearance. Each slat is crafted from FSC-certified MDF, offering a more sustainable choice while remaining lightweight! These wood slat panels are DIY friendly, though you may prefer a team of two for fixing! A high-performance acoustic felt backing adds both strength and functionality, helping reduce echo and absorb sound, especially when fitted following the Trepanel® Guide. Finished in a real wood veneer, the slats display the texture, natural grain and variation of real wood, with a cool, modern ash grey shade to add character and depth.

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.

Cleaning and Maintenance

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.
