How to Install Rigid Foam around Windows - buildaroo.com

Terry applies furring strips onto the sheathing to bring out the wall to a more protruded level. Rigid foam is then put on after this step, and it offers a continuous insulation around the wall with no thermal breaks, commonly pipes and other openings around the wall. Rigid foam is essentially a continuous skin that is unbroken, and it is made of polyisocyanurate with foil on both sides. This rigid foam has the highest R value per inch of any insulation, R6. An alternative to this is Foamular which has an R value of 5 per every inch.

The foam is put on, and one see right away why the furring strips are put on. By putting on the furring strips, a leveled surface is formed between the rigid foam and window frame. Sealant, a foil stick back for instance, should be applied between the furring strips and rigid foam. The rigid foams should be taped together when they meet side by side. The window is then put on top of the furring strips, and again, air and water sealing is applied around the edges of the window. There are many ways to seal the windows; Terry and Peter just show one of many.
