Why You Should Have Attic Stair Insulation 

There are multiple benefits of attic stair insulation. The first is that it’ll help with protecting your home. In colder climates, most of us turn up the heat to stay warm, and the moisture ends up creeping upwards through the ceiling and into the attic. The contrast in temperature can result in a slew of issues for your home from mold to mildew growth and can cause severe damage to your roof. With the proper attic stair insulation, you won’t have to worry about that problem.

Another great benefit is that attic stair insulation can help with saving money in the long run. While you’ll need to ensure that it’s properly installed, it’s great for energy efficiency within the home. It’s also not expensive, so it’s a cost-effective way to keep warm air in and cold air out – no matter the time of year.

Attic stair insulation can also help with making your home more comfortable since the sealing will prevent drafts. It’ll also prevent unwanted heat loss and heat gain and ensure that your home stays at a comfortable temperature all year round.

Finally, attic stair insulation can keep pests out of your home. If you’ve got cracks or gaps in your attic, bugs and pests can enter your home. By sealing the access with an insulation cover, however, they won’t be able to sneak in through the cracks. With the right amount of ventilation and a proper attic stair insulation cover, you’ll be well on your way to keeping your home pest-free.

Features of Good Attic Stair Insulation

Before discussing what to look for in attic stair insulation, you’ll first have to consider the two different types of covers. There are attic tent insulation covers and a zippered attic insulation blanket. Attic tent insulation covers make a little tent above your stairs, and you’ll just have to move the attic cover out of the way when you go up and down the stairs. While it’s easy to install and move, it doesn’t provide a great seal.

For the zippered attic insulation blanket, this is stapled to the framing of the attic stair opening and is zippered all around the opening. To enter the attic, you’ll need to unzip the opening for entry. The advantage of this cover is that it provides a better seal, but it’s more challenging to install, and you’ll have to toss the cover if the zipper breaks.

When it comes to selecting your attic stair insulation, you’d want to consider the materials. Make sure that it’s made of high-quality materials, and if you’re buying a zippered attic insulation blanket, you’d want to also check the seam strength and zipper quality.

Finally, you’ll need to consider the design. Attic tent insulation covers, for example, come in a wide array of designs, so you’ll need to pick the one that suits your attic best. Another thing to consider is size. Attic insulation covers come in various sizes, so you’ll want to make sure that it’s big enough to insulate the attic opening. Just in case, you should have a 2 to 3-inch margin of error.
