Hybrid Insulation with Fiberglass / Cellulose

Sometimes the Best Solution is a Hybrid

Over the years Seal It Insulation Systems has, on occasion, installed hybrid insulation systems. Our hybrid installations can incorporate our signature spray foam material along with fiberglass and / or cellulose materials. Although thermal efficiencies are much lower with non air-barrier materials, sometimes budgets do not allow for 100% use of spray foam insulation. By incorporating the installation of non air-barrier materials like cellulose and fiberglass, Seal It gives the contractor and homeowner complete control over the affordability of their insulation project while incorporating proven air-tight insulation technologies to keep you comfortable through Maine's (sometimes brutal) winter season.

Why Fiberglass Insulation?

Fiberglass insulation products are considered by some to be among the most versatile insulation products available on the market. Because a wide range of fiberglass products (with varying performance levels available) exist, the use of fiberglass allows our Seal It installation professionals to really fine tune the exact capacity of your insulation project. R-values for fiberglass insulation can range from 2.9 to 3.8 per inch of thickness (but can get as high as 4.3).

Wondering What an R-value Is?

R-value is the measurement of an insulation material's capacity to resist heat flow. Simply put, the higher the R-value, the greater the insulating power you'll receive. However, remember comparing R-values between "air-barrier" insulations (i.e. spray foam) and “non-air barrier” insulations is like comparing apples and oranges- confused? Ask us about this very important fact!

What About Cellulose Insulation?

Cellulose insulation is derived mostly from recycled newsprint and is often applauded for its eco-friendliness and total-fill properties. Cellulose insulation also packs a slightly stronger punch (on average) than fiberglass, delivering R-values in the range of 3.6 to 3.8 per inch.
