Underlay is the term for a thin material such as fiber, felt, rubber or foam, that is laid between the subfloor and the floor. Underlays are useful for stability, insulation, sound reduction, cushioning and moisture protection. Underlay is commonly used for floating wood floors. Fixed floors do not usually incorporate an underlay as they are fixed directly to the subfloor.
For years the underlay we today call “combilay” has been a most suitable and cost effective underlay for the flooring industry.
Combilay is made of a 2mm thick aerothene that is laminated onto a clear 80 micron virgin plastic moisture membrane, with a 100mm overlap on the one side that is to be taped down.
The next generation of “Floating Floor” underlay is now here. FINIXPE underlay is a premium acoustic underlay made up of a 2mm sound dampening high performance Irradiated Cross-Linked Polyethylene (IXPE) extra fine foam , with an overlapping vapour barrier of 80 micron HDPE (High Density Polyethylene), for extra moisture protection at the joints.
Easy to install with easy peel tape to adhere to the overlap
A commercial crumb underlay designed for domestic or commercial installations for both soft and hard flooring. Manufactured from a high content of selected, recycled tyres bound in a unique latex formulation that delivers exceptional resilience and durability.
A combination underlay consisting of a 2mm rubber underlay laminated with a 300 micron moisture membrane made of virgin plastic.
Foam 8mm Thick Carpet Underlay, low-cost budget underlay suitable for all subfloors and applications in normal to heavy household use.
Made from expanded aerated polyethelene, it’s the modern technique to advance the appearance and durability of carpet installations. Spill guard carpet underlay is a replacement for the old-fashioned underfelt, which is an unhealthy haven for dirt, dust, and bacteria.
WHY DO I NEED UNDERLAY?
Underlayment is a must! Some flooring options come with an underlay attached to the underside of the flooring panels. If there is an underlay attached you are still required to use a moisture barrier, which is either a painted or 80 micron HDPE plastic underlay.
Since our laminate and engineered wood flooring ranges make use of a floating floor installation, the underlay must be evenly distributed across your subfloor. Underlayment is what allows the floor to float, gives it stability, support, noise reduction, and supports the locking systems in between planks to assure the sturdiest flooring project.
