Air leakage Throughout the Home Could be Causing High Hydro Bills

June 25, 2017

In North America, air leakage in and around the home is the main cause of higher-than-average energy consumption. This results in high natural gas bills and high hydro bills. On the flip-side, a well-sealed home is a home that is energy efficient. Simply put, energy efficiency results in reduced utility bills. In winter, air leakage can quickly turn into high gas bills for heating. And in summer, air leakage could result in high hydro bills for air conditioning. Either way, wasted energy is money down the drain.

Reduce high hydro bills by stopping air leakage in your home

Stopping air leakage is the key to better energy performance, and here, good insulation can make a big difference. Good insulation will provide both air tightness and thermal protection for the "building envelope". In fact, a properly insulated home will significantly reduce energy waste that's caused by air leakage. And that means reducing high gas bills and high hydro bills in winter and summer. But it also means properly insulating the roof, attic, exterior walls, and even the basement foundation walls. Many insulation contractors concur that spray foam insulation is the best remedy for air leakage issues. The annual dollar savings make the initial investment worthwhile, and long term, the home is much more comfortable. With a professional install, spray foam insulation simply reduces heating and air conditioning costs throughout the year. It makes it possible for homeowners to avoid high gas bills and high hydro bills. Best of all, spray foam insulation provides both air sealing and thermal insulation. For the homeowner, the benefits of a well-insulated home go far beyond saving money on utilities. In terms of comfort, the home becomes warmer in winter and cooler in summer. As well, air circulation and air quality are noticeably improved. And finally, indoor air moisture is far better controlled, which diminishes moisture related problems throughout the home. When professionally installed, spray foam insulation can accomplish it all, and in a single application. High hydro bills will be in the past. As a high performance product, spray foam insulation seals and insulates air leakage better than anything comparable. The finished space is completely air-tight, including the hard-to-reach spots that pose installation problems for other products. Expertly installed, spray foam enhances energy efficiency throughout the home. The HVAC system works better; energy consumption is reduced; and seasonal utility bills are lessened. In short, it's one of the best returns-on-investment for a homeowner.
