A replacement system is the simplest way of creating a new hardwearing surface, without significantly increasing floor height.
An additional benefit can be gained if it includes a resilient layer to reduce impact sound transmissions. TripleDeck is designed
to be a replacement for original floorboards when used in conjunction with an appropriately insulated floor void.
