The Attic Tent model AT-2 & AT-4 Solves on of the most common problems in most homes: uninsulated and leaky attic ladder stairs. What is the problem? 


Your attic door provides two ways for your home to loose valuable energy. First, it is basically a hole in the ceiling allowing air to pass through. Newer homes require the attic door to be sealed, but on older homes the attic staircase usually allows air to easily pass through. This is no different than leaving a window partially open. Secondly, most attic stairs are not insulated. This provides a channel for heat to easily pass through. It is essentially a "bald spot" in your attic floor insulation. This is known as Thermal Bypass. The Attic Tent is only intended to be use on staircases WITHIN the air conditioned living space (not needed for garages).

  • AT-2: 25" x 54" x 7"
  • AT-4: 25" x 54" x 13"
  • Seals & insulates in one easy step!

How Does It Work? 

The Attic Tent SEALS and INSULATES the Attic Stairs in ONE Step. The engineers at InsulSure solved the problem of attic stair air transfer/loss from the perspective of the homeowner. They designed a product that not only significantly reduces air loss, drastically lowering your energy bill, but also provides safe and easy zipper accessibility into your attic. It also keeps blown insulation up in the attic where it belongs, not on your floor, each time you open your attic stair door.

Can I Install It Myself?

The Attic Tent is easy to install in about 10-15 minutes. Anybody can install an Attic Tent. Installation is basically two simple steps.  First, staple the skirt around stair case (instructions are included with your purchase) and then, caulk around the tent to seal the skirt to wood frame. See the complete install instructions and photos below.

How Does It Save Energy?

There are two things you can do yourself to save energy in your home. Install Radiant Barrier and seal leaks into your home. The most common air leakage points are can lights, or recessed lights, leaks around windows and doors and the attic door or attic staircase. The Attic Tent will seal and insulate the attic staircase.

Choosing the Right Size Attic Tent

We sell two different model sizes: the AT-2 and the AT-4. The most popular size is 25" x 54" x 7" which is the Attic Tent Model AT-2. This is the size needed for most standard size attic stairs. Measure the distance across, it should be about 25". The attic tent sticks up in the attic about seven inches. Combined with the thickness of standard ceiling joist of 5 1/2 inches you will have enough room for a standard triple fold attic staircase.

The AT-4 is 13" TALL. It has more clearance for ladders that stick up further into the attic (usually 4-part fold ladders). Visit the manufacturers website for more info on sizing

Determine where you are going to staple the skirt. Ideally, you will staple to the frame around the top of the stair opening.

If you have decking or and uneven spot, use your staple gun and follow the contour of the opening. The main goal is to create a continuous connection between the attic tent and the opening of the attic staircase. Use 3/8" or 1/2" staples.

Stand at the top of the stairs. Position the Attic Tent so the opening where the two zippers come together is at the top of the stairs.

If you have too many obstructions, you can staple to the inside of the framing. You will have some excess material in the corners. Just staple the excess to the framing.

Position the Attic Tent on top of the framing. Be sure to position so that you will have a solid frame to staple all around.

The Attic Tent will zip closed for easy, but air tight, access in and out of the attic.

Put one staple on each corner to hold in place. Pull gently to make sure the Attic Tent is flush with the top of the framing. Remove staple and reposition if needed. 

Put one staple in the MIDDLE of each side to line up skirt with the frame. Ideally you will put the staple in the middle of the skirt. This will enable you to easily caulk the skirt to the frame later.  Then proceed stapling all around the skirt about every 2 inches until complete.  This completes the attachment part of the install.  Now let's makes the attic door airtight.

AtticTent caulk to seal AtticTent - sealing with expanding foam

Caulk the Attic Tent to the framing. Use a good quality silicone caulk. Insert the tip between the Attic Tent skirt and the framing. Squeeze a continuous bead around the frame. Gently press the skirt into the caulk to insure a continuous seal. Now use caulk and seal the corners of the framing and plywood decking to the framing (if you have decking).

The last step is to seal between the attic staircase and the framing. This is best done with a disposable can of expanding foam like Great Stuff. Follow directions on the can and fill the cavity between the frame and the attic door from the bottom (sheetrock) about 1/3 of the way.  The foam will expand up and beyond the top of the frame. Be careful not to spray too much since the foam can expand beyond the area and end up squirting out under your stair case trim. Start with a little, you can always add a little more a lot easier than you can take it away.
