Because the attic is out of sight for the most part, homeowners tend to neglect that part of the house when it comes to insulation. But for insulation contractors, the attic is essential for ensuring energy efficiency, reducing energy consumption, and providing seasonal comfort. Utility bills are always on the rise, so homeowners are paying much more attention to home insulation, and becoming more aware of the options for conserving energy and reducing utility bills (heating and air-conditioning).
It’s all about sealing, insulating, ventilating
The attic is a unique space that requires effective sealing, high performance insulation, and proper ventilation. All three are necessary because of the air and moisture dynamics of the attic. Therefore, addressing all three will ensure optimum energy efficiency overall. For homeowners with existing attic insulation, things may be adequate, but unless the space is sealed, insulated and ventilated, the “system” can’t work efficiently for maximum performance. Ventilation is critical in the attic, and without it, even the best insulation won’t perform. A poorly ventilated space will allow moisture to collect, and will assuredly compromise insulation value. In the long term, this could lead to bigger problems, when moisture begins to actually damage the space.
Attic insulation should not be a DIY project
Today, many home improvement centres are promoting DIY options for attic insulation – and that includes sealing, insulating, and ventilating. However, it takes an expert installer to really do the job right. Experts have extensive product knowledge; they have in-depth installation expertise; and they know what to do when it comes to troubleshooting. With a professional install, customers are also assured of reliable warranties for both product and installation. As well, professionals do a comprehensive job from start to finish: they thoroughly inspect the existing condition of the attic; they assess which product or products will best suit the needs; and they decide which installation will deliver the best return on investment for the homeowner.
Product options ideal for attic insulation
One of the more affordable product options for the attic is “blown” insulation. It’s “fluffy” in nature, and is designed to restrict air movement, while providing good R-Value. This product is fabricated to be fire-resistant and mould resistant – the ideal for an attic. When professionally installed, the “blown” insulation product is a cost effective option.
Probably the best product on the market for attics is spray foam. It delivers more benefits than any comparable product, and it does it in a single application. It blocks out air movement, prevents moisture from collecting, and insulates with very high R-Value. Spray foam envelopes everything in the attic – beams, wiring, plumbing, and ductwork.
Some contractors are now recommending a “hybrid” installation for the attic and roof cavity. This approach combines the “blown” insulation product with the spray foam product in one install. Here, the spray foam effectively seals and insulates, and the “blown” insulation adds additional R-Value where required. The “hybrid” approach is extremely cost effective, with excellent long term results.
