The roof of your home or commercial building has more functions than just the visible material that covers it. One of the most important is insulating it to keep heat inside when you need it and outside when you don’t, and that in turn helps lower your energy bills, protects the structure, and helps you become more sustainable.
When it comes to insulation roof, there are many options out there. You can choose from a variety of materials including traditional fiberglass batts and spray foam, as well as natural alternatives such as cellulose insulation. You can also use a reflective radiant barrier to prevent cold air from entering your home and heat from escaping.
Insulation Roof: Key Considerations for Effective Installation
Fiberglass insulation is a popular choice since it’s affordable and easy to install by your roofers. It also has a good insulating value, called R-value, for most climate zones. Other options include blown-in cellulose insulation, which is made of recycled newsprint and paper and can be installed in hard to reach areas. This type of insulation, which is usually applied to wall studs and ceiling joists, also has a low embodied energy content compared with other types of roof insulation.
You can also opt for a more modern roof insulation material such as spray foam, which is applied by professionals and expands to fill cracks and crevices in the attic space. This type of insulation is water-resistant, doesn’t appeal to rodents and has a higher R-value than fiberglass. It’s also fire-resistant and can seal around plumbing vents.
