AK Insulation also offers Hybrid Insulation service. This is the most affordable and best service that is out there. Also known as the Hybrid Wall Package. The Hybrid is a one pass of closed cell foam which is one of the best insulations on the market. It serves as a vapor barrier and boasts one of the highest R Value’s on the market per inch. It also adds 1/3 racking strength to any walls it is installed in. The cellulose, which is good by itself, is the icing on the cake. Cellulose is one of the best sound deadeners on the market and boasts a one hour fire wall. You could spray open cell over the one pass of closed cell, but you would lose the fire wall. If you were to totally fill the cavity with closed cell, the cost would be crazy high. It is nearly impossible to shave off, unlike the porous open cell products, because of its rigid hard, soul-crushing density. This is the best package AK Insulation has to offer. This is becoming a popular service and in high demand, so be sure to give AK Insulation a call today for any prices or estimates at 618-790-4685.
