Residential and Commercial Buildings
Underlay is the layer installed beneath a timber floor to improve comfort, performance and sound reduction. Pentarch’s ecoCORK Insulation Acoustic Underlay is a natural, non-toxic underlay made from cork, offering excellent acoustic and thermal insulation. Available in 3mm and 5mm thicknesses, this underlay suits both residential and commercial buildings and is suitable for use under a wide range of timber flooring products.
Floating floor underlay sits beneath a floating timber floor without being glued or fixed to the subfloor, allowing the floor to expand and contract naturally. Pentarch’s cork underlay is suitable for floating floors as well as direct stick installations, giving flexibility across different flooring methods. Its light weight makes floating floor underlay easy to install, while its natural compressibility and recovery support long term floor performance.
Acoustic underlay is designed to reduce noise transfer between floors, an important consideration for apartments, multi-level homes and commercial buildings. Pentarch’s ecoCORK acoustic underlay achieves a 5 Star Rating (AAAC) and Lnt,w acoustic performance of 44 to 45 depending on thickness. Made from 100% natural cork, this acoustic underlay also provides thermal insulation benefits alongside its sound reduction properties, helping create a quieter, more comfortable living space.
