Spray Foam Insulation Can Reduce Energy Consumption

May 28, 2017

A home that is sealed and insulated with spray foam insulation can reduce energy consumption. This is true in both winter and summer, since energy efficiency is enhanced throughout the entire home. Simply put, improved energy efficiency makes for reduced energy consumption, and therefore reduced utility bills. Homeowners can save on winter heating and summer cooling.

Optimize Energy Efficiency with Spray Foam Insulationgreen house spray foam insulation can reduce energy consumption

One of the better approaches when addressing home energy efficiency is to install spray foam insulation. This is especially relevant when the objective is to reduce energy consumption. Spray foam will ensure air tightness and thermal protection at the same time. It will prevent heated air (in winter) and cooled air (in summer) from being completely wasted through air leakage. Air leakage in a home's "building envelope" is ever-present - in the attic, roof, and even the basement foundation walls. In order to reduce energy use, air leakage must be arrested, and here, the solution is spray foam insulation. Overall, the application provides a homeowner with better return-on-investment than most other product applications (or combination of products).

Reduce air leakage with spray foam insulation

Installing spray foam allows for the ultimate in air sealing and thermal insulation. Spray foam insulation will make a home warmer in wintertime and cooler in summertime. It will reduce energy consumption, improve indoor comfort, and enhance air circulation. In addition, spray foam controls the movement of air moisture, reducing the chances of moisture related issues. When professionally installed, spray foam insulation creates an airtight environment that eliminates the need to install a separate vapour barrier. This in itself inhibits the movement of air moisture and the accumulation of moisture pockets. Winter and summer, the better-controlled moisture levels make for a more comfortable (and healthier) indoor living environment.

The aim with spray foam is to optimize energy efficiency. With a good install, the HVAC system will operate in better balance, allowing for less energy to be used throughout the year. In many homes, annual savings on heating and cooling can actually "pay down" the cost of the original spray foam installation. This can be quite important when the entire home is installed. At Great Northern Insulation, experienced residential installers specialize in spray foam. All products are installed to code, and every application follows the manufacturer's specifications.

In fact, GNI guarantees homeowner satisfaction on every job, regardless of size. GNI installs only quality insulation products and provides superior installation work from start to finish.
