Polysource Idaho Your number one distributor for North Idaho, and Western Montana providing Arxx Building Products and High Performance Wall Systems.

The Arxx Wallsystem consists of interlocking, lightweight, expanded polystyrene forms. Designed to be an integral part of the wall, these forms remain in position after the concrete is placed. The insulating capacity of expanded polystyrene coupled with the structural integrity of reinforced concrete is a powerful combination — it makes Arxx walls stronger, safer, quieter and more energy efficient.
