Rigid Foam Wall Insulation

Don’t be a victim of water damage, losing R-value or even mold absorption as well. Go for the SilverGlo insulation. This is innovative rigid foam insulation that creates an effective thermal as well as an air barrier.

About Rigid Foam:

In recent times, rigid foam has continually grown in popularity particularly among homeowners and builders. This is quite surprising considering the dominance of fiberglass and cellulose in this industry over the years. It is an ideal wall insulation solution among many other applications.

Although there are various types of rigid foams, all these types have one primary advantage; when adequately sealed with special tape; rigid foams prevent air leakage as well as avoid penetration of water and absorption of mold.

Generally, rigid foams come in different thicknesses and widths and are available in standard 4 x 8 ft. panels and 2 x 8 ft. panels. Additionally, this foam is a lightweight option and is quite easy to cut even when using a knife.

Rigid foams are primarily used to insulate standard masonry walls. In such case, they are glued to these walls with adhesive although masonry fastener may also be used in securing the panel.
The law mandates for the foam to be covered using fire-proofed materials. Nonetheless, rigid foam creates a substantial thermal barrier subsequently promoting energy efficiency.

Types of Rigid Foam

As aforementioned, rigid-foam insulation is the best way to gain R-value and prevent water and mold leakage.

There are three main types of rigid foam mainly:

1. Polyisocyanurate

Commonly referred to as polyiso, this is the foam with the highest R-value per inch of any rigid foam insulation at R-6. Polyisocyanurate is widely used in typical roofing applications. What’s more, it also includes a barrier reflective radiant foil on each side for several applications. Nevertheless, despite these unique qualities, it is, however, the costliest compared to other foams.

2. Extruded Polystyrene (XPS)

This type of rigid foam comes in two distinct colors: pink and blue. It features among others a relatively good R-value of approximately R-5 per inch not to mention a smooth (plastic) surface. It is mostly used in walls as well as below grade applications. This rigid foam is also conveniently recyclable.

3. Expanded Polystyrene (EPS)

This is yet another type of rigid foam. Of the options above, this is the most economical option. It is also the most versatile type. EPS has a decent R-value of approximately R-3.8 per inch. These foams come in numerous and varying thicknesses which subsequently offer versatility. You can make them airtight by taping all the areas in between each of these foam boards.

Usually, the importance of a thick air barrier is to boost the energy efficiency of your home and make it more comfortable. Generally, EPS is mainly used in walls, roofs, structural (GeoFoam) applications, Below Grade applications, and floors.
