Hybrid Insulation Installation

2lb spray foam is spayed to wall cavity, electrical wires a re run, and finished with 1/2lb foam .

(2)lb spray foam is spayed to wall cavity, electrical wires are installed and the wall is sprayed a second time with (1/2)lb foam .

Techniques to improve your living conditions are the focus of insulation contractors in 2015.

Insulation contractors are using a variety of hybrid techniques to install insulation and we want to show you this one! Recently we spotted a home contractor selling his new home, constructed with an all-steel frame from NexGen Framing Systems.

This technique is very similar to the one used by batt insulators who install foam and then fiberglass, like that mentioned on GreenBuildingAdvisor.com.

This technique is called Flash Foaming

The wall cavities were sprayed with (2)lb foam; just enough to seal the wall. They were careful to only fill about an inch of the cavity. This left just enough room for the electrician to install his electrical wires and fiber optic cables.

Once these are installed the spray foam installer comes back in with a lighter, more pliable foam, known as half pound foam, (its similar to shave cream).

They fill the remaining part of the wall cavity to improve r-value and deaden the space for sound reduction. Doing the installation like this is a safe precaution in case anyone ever needs to get inside the wall to move wires, etc.

The home was then finished off with foam board exterior insulation, which is underneath beautiful, creme colored Hardie board siding.¬†Foam Insulation¬†is commonly referred to as the best insulation in it’s class for it’s superior insulation properties, the fact that it doesn’t shrink, or allow mold or mildew to grow on it.

In addition foams of today are non gassing and are engineered to reduce flame spread in case of fire. Foam used in building structures is typically recyclable as well.
