Attic stairs are an important part of your home. They allow you to access your attic, which is a great place to store things and keep them out of sight. However, they can be a major source of air leaks that let warm or cool air escape into the rest of your house. Adding some insulation will help prevent this problem and make your attic more comfortable year-round! St Louis Park Spray Foam Insulation

Adding attic insulation to your stairs is a great way to keep your home more comfortable and energy-efficient.

Adding insulation to your attic stairs is a great way to keep your home more comfortable and energy-efficient. As the name suggests, attic staircases are frequently located in attics. The temperature of an attic can fluctuate dramatically; it’s generally much warmer than other parts of the house, but as heat rises, it can also get quite cold in winter if there isn’t enough insulation up there.

Staircases typically have minimal insulation: just enough to block drafts around the doors and windows that lead into them. This makes sense since you don’t want too much heat escaping through these openings—but it does mean that cold air will flow down into them during winter months, making those rooms colder than they would otherwise be.

Adding extra attic insulation will help keep those spaces warm by blocking air flow and trapping in warm air near where people spend most of their time at home: living rooms below stairs rather than bedrooms above them!

Attic insulation is usually done by a professional contractor, but you can handle adding insulation to the stairs yourself.

If you don’t have a professional contractor on hand, but still want to insulate the attic stairs, it’s possible to do so yourself. The process will take most of a weekend—you’ll need to remove the existing insulation and re-install it after installing insulation batts between the joists. This is a good project for someone who wants to learn how to insulate an attic without spending a lot of money on labor costs.

If you’re going to tackle this job yourself, make sure that you wear protective clothing (including eye protection and a dust mask) as well as closed-toe shoes.

Before you begin, make sure there are no issues with the attic stairs that need to be resolved. St Louis Park Spray Foam Insulation

Before you begin, make sure there are no issues with the attic stairs that need to be resolved.

  • Check for air leaks. If you feel cold air coming through the stairs or find drafts around them, there may be a problem with insulation and/or ventilation. Fixing it might include adding more insulation to seal up cracks, repairing damaged or missing shingles on your roof or sealing off any ducts leading into the attic from other parts of your home (and vice versa).
  • Check for structural issues. If your attic stairs are sagging or uneven and not sturdy enough to walk on safely, they’ll need to be repaired before being insulated—otherwise, putting more insulating materials over them may weigh them down too much and cause them to fall apart completely!
  • Remove moisture buildup in insulation if necessary by gently brushing it out with an old brush or whisk broom (be careful not to stir up dust!). Water vapor in attics can cause mold growth—which can become toxic when inhaled regularly over time—so this step is extremely important when dealing with moldy areas of your home such as attics!

Measure and cut pieces of rigid foam board according to the size of the stair opening.

Once you’ve decided on a method for insulating the attic stairs, measure and cut pieces of rigid foam board according to the size of the stair opening. If you’re insulating a large space, such as an attic ladder or set of attic stairs, this can be tricky because it’s difficult to tell exactly how long your insulation pieces should be without seeing them in place. This is where measuring comes in handy: if possible, find someone who can measure while you hold up your piece of rigid foam board; otherwise just take turns!

Once you have measured out your material and cut it so that it will fit around whatever section or sections need covering (in my case I had two different openings), check their size again against those measurements before proceeding with installation.

Using a caulking gun, apply expanding spray foam around the edges of the foam board and insert it into place. St Louis Park Spray Foam Insulation

Spray foam is a great insulator, and it’s not just for walls and roofs. Spray foam will fill in any gaps that exist between the foam board and the ceiling joist or rafters, so there is no need to worry about air leaks around your attic stairs. Spray foam also acts as a good sound barrier when applied to walls or floors, making it an excellent choice for soundproofing your house if you live next door to noisy neighbors.

How does spray foam work? When sprayed onto surfaces like wall studs, sheetrock or plywood sheets with perforations in them (called cavities), expanding polyurethane foam expands into those cavities and fills them completely with polyurethane plastic.

Spray foams are rated based on how much pressure they can withstand before bursting—the higher the PSI rating number on your can of spray polyurethane insulation, the more pressure it can withstand without bursting open! This makes them great for sealing out drafts through windowsills; just place strips of duct tape along each side before spraying so they don’t get messy while waiting around after application.

Open a new can of spray foam and spray it around the edges, making sure to shut it tight.

  • Open a new can of spray foam, and spray it around the edges. Make sure you shut it tight when you’re done!
