The Secret Behind Well Insulated Attics: What You Need to Know

← Back to List
No two attics are alike. Yet, they share at least one commonality. Attics are located directly under the roofline of residential structures and require some special consideration. Without question, something can be said for well-insulated attics.

Attics are used for a variety of reasons. In some cases, they are actually converted into living spaces, complete with HVAC and ducts. Meanwhile, others are merely used for storage and are essentially unfinished. However, the latter does not negate the importance of insulation.

The shape of an attic often offers some challenges when it comes to insulation.  A number of attics are difficult to stand in – and are seemingly more representative of crawlspaces. The structure design may even dictate the propensity for air leakage.  This can represent both a feeling of discomfort in warm weather – as well as a drafty environment when temperatures drop.

Spray Foam Insulation and Attics

Air leakage occurs in attics quite frequently because of its proximity to the roofline. For this reason, it makes sense to seal off vulnerable areas with spray foam insulation.

Why spray foam insulation and not fiberglass?  For one, spray foam is the most adaptable type of insulation. You don’t have to worry about cutting down batting to size. Of course, you could try blowing in fiberglass, but it’s not nearly as effective as spray foam insulation.

Where do you use spray foam insulation in protecting attics?  You could start at the roofline and continue to the attic floors. In doing so, you’re not just creating an impermeable sealant against moisture and air. You are also cutting down on noise levels. Of course, the added incentive is the savings in utility costs.

Here’s another thought. What if your customer wants to convert an unfinished attic into living space? Insulation is obviously key to that project as well.  Because of their location, attics are often the hottest place in the house. Spray foam insulation helps eliminate the stuffiness associated with attic rooms.

Like every insulation project, it is important to understand what product works best. Should you go with closed cell or open cell insulation?  What is the best R-value to ensure efficiency?  These questions should be addressed by experienced spray foam insulation advisers.
