Trepanel XL® Smoked Oak is the larger-than-life choice for creating that trendy wood slat style in your unique home design with an innovative wide slat format and extra-long 3m size, perfect for high ceilings! Our panels have a strong felt backing with excellent sound-absorbing qualities, perfect for helping reduce echoes in larger spaces when installed following the Trepanel® Guide. Constructed with an MDF core, which is so lightweight and easy to cut it can be installed by one person (although you may prefer a team of two for fixing), our wood slat panels are fast to put up and create minimal mess, so you can transform a space in minutes! The long wood veneered slats have the characteristics of real wood in texture, colour variation and grain and their warm, medium brown oak shade is visible from all angles.

Fixing Guide

To fix Trepanel® we recommend using either black matt coated 38mm screws or Mapei Ultra Super Grip. One panel requires 21 screws or 1 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 for 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, 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 there is 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.
