The AirStep utilizes a product construction technology that allows for better installations and controlled stability, rather than the dimensional stability of fiberglass products. This means that as the home contracts, due to cooler weather in the winter and expands with warmer weather in the summers; your AirStep floor will do the same, preventing gaps at the perimeter. Whereas with fiberglass floors, which are dimensionally stable, when the home contracts your flooring stays the same size, potentially creating buckles and bunches in the middle of the room. When the home expands with warm weather, the floor stays the same size, leading to gaps at the perimeter of the room.
The AirStep products can be loose laid, perimeter adhered or fully adhered over a wide variety of substrates, without the worry of buckling. AirStep has a lay flat, stay flat, no buckle guarantee.
