Five Common Types of Roof Insulation

Fiberglass

When most people think roof insulation, they envision the long rolls of pink fiberglass batting that gets stuffed between rafters. While this may be stereo-typical, it is also highly accurate. Fiberglass sheets are actually constructed using small pieces of glass that have been crushed, melted and mixed to form a cotton candy like consistency. This type of insulation is relatively inexpensive, but it can be difficult to install. Hand and skin protection as well as a face mask must be worn during insulation to prevent cuts and avoid lung damage. 

Wood Fibers

Specially treated wood fibers are compressed, molded and bonded together to create a highly effective roof insulation. Other organic and non-organic binders and fillers are added to the insulation's construction to form an effective material. Wood fiber roof insulation typically comes in board form and can be installed by experienced do-it-yourself homeowners.

Recycled Cellulose Fiber

While this product was not widely known about a decade ago, today, recycled cellulose fiber insulation is one of the most environmentally friendly roof insulation options. Made from recycled newspapers and other paper products, this insulation is treated with a superior fire retardant and vermin repellant material that keeps it safe from flames and rodent teeth. Although it can be found in rolls, when it is installed as roofing insulation, it is typically sprayed on with a high-pressure machine. This can be a slightly messy procedure, but it is highly effective when battling the drafts of winter and heat of summer.

Gypsum Board

Highly water-resistant and non-combustible, gypsum board is another common roof insulation option. While it is usually used as a cover board, it can also be used as the primary insulation product. It is particularly good as a barrier against heat and cold, as well as, moisture and dampness. Foam Polyurethane foam is commonly used in roofing insulation, as it is highly insulating and can be sprayed in place. This type of spray on foam actually expands to fit the area that it is applied to. Although best applied at the time that the home is being built, it can be applied later if done by a certified contractor. It may be tempting to install this type of insulation on your own, but foam is best applied by someone who has experience and can judge the correct amount of foam for the job. Selecting the right type of insulation for your roof depends on your budget, as well as, the structure of your home. It is best to consult with a professional since the wrong type of insulation or improper installation can damage your home’s structure.
