RetroFoam™ is an extremely safe type of insulation to introduce into your walls. Unlike polyurethane foams which you can purchase from your local hardware store, RetroFoam™ home insulation is a modified plastic foam, installed by a trained technician. The expanding agent in RetroFoam™ is compressed air. RetroFoam™ is fully expanded prior to entering your walls. RetroFoam™ meets government guidelines, does not create a fire hazard, and has high R-value.
Retrofoam becomes a lightweight solid unit of insulation inside the voids it fills helping keep out rodents and air movement unlike loose-fill products which are not solid units. Loose-fill can be shifted by compaction and/or rodent nest building allowing for increased levels of air movement. If at any stage you need to carry out wall alterations, the solid customized blocks of foam can be easily removed while work is in progress and simply replaced on completion. If rewiring is needed, wires can be pushed through the rigid foam, or the foam can be cut if necessary.
