When Doing Home Renovations, It's Wise To Think About Home Insulation

June 19, 2017

Today, many home renovations focus on the kitchen and washroom, with an emphasis on the Home renovations insulationcosmetics - things like counter tops and plumbing fixtures and fancy cabinetry. From time to time, there may be some focus on home insulation, perhaps when the basement or roof is being renovated. But overall, there isn't enough emphasis placed on home insulation, something that can provide real value to the home, along with meaningful dollar savings season to season. Whatever the scope of home renovations, it's wise for a homeowner to think about installing home insulation as part of the overall project.

From attics and roofs, to basements and "bonus" rooms, home insulation can be a very practical add-on that provides comfort to a living space while making the home far more energy efficient. In fact, energy efficiency can lower utility bills year after year, even to the point of offsetting the original cost of the home renovations. Just by example, installing attic insulation with a high performance spray foam product will provide both thermal protection and air tightness at one time. For those who are doing home renovations in the roof and attic, the added insulation work has benefits for years to come. In fact, spray foam insulation makes for exceptional return-on-investment - so much so, that heating and cooling savings can often "pay down" the project cost within a few short years.

The truth is, a well-insulated home delivers benefits to the homeowner that go beyond dollar savings

To begin with, the home is a more comfortable living space during the extremes of winter and summer. Additionally, air circulation and air quality are improved, especially when insulation and ventilation are addressed in tandem. Finally, good insulation also controls indoor air moisture, which serves to reduce moisture-related issues throughout the building envelope. What's important with any home insulation project is to have the work done professionally. The installed products must suit the need and the installation work must ensure performance. With Great Northern Insulation, home energy and home insulation are addressed in a comprehensive manner, with the aim of delivering both comfort and savings.
