Sealing Your Attic Hatchway

Most homeowners don’t realize that the pulldown attic stairway is one of the biggest heat loss culprits in the house. Many of us don’t go up into the attic very often other than to get holiday decorations from storage or maybe grab the suitcases for an upcoming vacation. Because we don’t access the attic all that much, we often don’t realize how much the temperature up there fluctuates and how much heat and air conditioning we are losing through the space. 

I can’t tell you the number of times that I have gone into an attic to find frozen water droplets on the tips of the roofing nails. Because homes are underinsulated and underventilated, the attic gets very hot in the summer and below freezing in the winter. Condensation and moisture can become a major problem, causing rot in the wood and mold on soft surfaces. 

But then of course there is the heat loss issue. We all know that heat rises and because most Connecticut homes are majorly underinsulated, we end up losing tons of warm air through the attic hatch. Plenty of people use draft strips and different kinds of sealant on doors and windows, but this entry point is almost always overlooked even though it’s the most important. The same goes for whole-house fans.

One of the common solutions we always recommend is installing an insulated box to cover the attic entryway or a built-in house fan. An insulated box is made from heavy-duty insulation and sealed with expanding foam. The box sits on top of the stairs when they are folded inside the attic, creating a barrier that still allows the homeowner to access the space as they need to. This simple structure reduces the amount of heat loss seeping from the living space of the home, making for a much more comfortable and energy-efficient environment. 

I always recommend that homeowners have their insulation and ventilation checked to keep their homes healthy, reduce their energy bills, and live more comfortably. While insulation is a very cost-efficient and easy home improvement, an insulated box is an excellent solution to achieve some of the goals of an insulation-optimized house for just a few hundred dollars. You’ll be shocked at the difference it makes.
