Weatherseal Insulation offers a full range of insulation materials for new construction and retrofit projects across Virginia, including spray foam, cellulose, fiberglass and more. But what is the best insulation material for your project, and how do you choose? As Virginia's trusted insulation experts, Weatherseal Insulation is here to help you figure out the best option for you.

A few of the factors that you should consider when choosing the right insulation material for your home or business:

Energy Efficiency

Energy efficiency is a major factor for many homeowners, business owners and builders and contractors, and for us here at Weatherseal Insulation. Energy efficiency is determined by a combination of R-value and installation quality. R-value signifies the thermal resistance of an insulation material -- the higher the R-value, the better an insulator. But, "rated R-value" may be different from R-value in the real world if an insulation is improperly installed. That's why we take care to maintain the highest standards when it comes to installing insulation such as spray foam, cellulose and fiberglass.


Environmental impact may be an important factor for you when choosing the right insulation for your home or business. Sustainability is determined by a number of factors -- energy efficiency, embodied energy, global warming potential and more. Spray foam, for example, is the most energy efficient insulation, but has a high embodied energy and global warming potential. Cellulose is made from recycled materials, and has a lower embodied energy, but a lower R-value than spray foam. There is no one-size-fits-all solution, and we here at Weatherseal are happy to work with you to help you make the right choice for your home or building.

Embodied Energy

Embodied energy may be a factor if you're interested in minimizing the environmental impact of your home or building. Cellulose insulation, for example, has a lower R-value than spray foam; but it has a lower embodied energy. Consequently, although spray foam is more energy efficient, cellulose may be the most environmentally friendly insulation material for your building. Other factors play a role in determining the overall environmental friendliness of the insulation material, including size of the building, lifespan of the building, and more. We're happy to work with you to help you determine the greenest insulation material for your project.

Upfront Cost

Of course, one of the major factors for building owners when choosing the best insulation material for their building is upfront cost. Spray foam -- a high R-value, energy efficient insulation material -- may save money over the long term, but it has a higher upfront cost than more economical alternatives such as cellulose or fiberglass.
