Attic hatch insulation turns the thin panel in your closet or hallway ceiling into a sealed, insulated door. A bare hatch is often a single layer of drywall resting loosely on a wood frame.

Warm air leaks around its edges, and the panel itself has almost no R-value. Even in an attic with deep insulation, a bare hatch leaves a cold, leaky patch the size of a small window. In many Kanata homes, the hatch is the last thing anyone thinks to insulate.

Attic Hatch Insulation details

What Attic Hatch Insulation Includes

We fit foam weatherstripping around the frame so the panel seals when it closes. Natural Resources Canada recommends closed-cell foam weatherstripping around attic hatches for this reason. Then we fix rigid foam board to the top of the panel to bring it close to the rest of the attic.

Where the hatch sits low in deep insulation, we build a short dam around the opening so the loose fill does not spill down when the hatch opens. That dam is part of our attic hatch insulation work on every top-up.

Pull-Down Stairs Need Attic Hatch Insulation Too

A pull-down attic stair leaves a large gap in the ceiling when it is folded up. We fit an insulated cover box over the stair opening in the attic, sealed at its base. It lifts off when you need the stairs, and it is the same attic hatch insulation idea on a larger opening.

Attic Hatch Insulation Is Part Of Every Top-Up

When we top up an attic, the hatch is sealed and insulated in the same visit, because a deep new layer with a bare hatch leaves an obvious gap. The blown-in cellulose insulation and attic air sealing pages explain the rest of that job.

Attic Hatch Insulation Price

On its own, attic hatch insulation is typically $150 to $400; a bigger opening, a dam or a stair box sits at the top of that range. When it rides along with a top-up, it shows as one modest line.

Work That Often Goes With This Job

Most Kanata attics get two or three of these done in the same visit, which saves a second trip.

Blown-In Fiberglass Insulation

Blown-in fiberglass insulation is loose glass fibre blown through a hose into the attic, where it builds a light, even layer over the ceiling. It does not absorb water and it does not settle much, which makes it a steady choice for an attic that will be left alone for decades.

Attic Insulation Replacement

Attic insulation replacement is a clear-out and a refill: the old layer is vacuumed away, the attic is cleaned, and new loose fill goes in to R-60. It is the answer when the existing material is soaked, mouldy, fouled by animals or crushed flat.

Attic Air Sealing

Attic air sealing plugs the holes in your top-floor ceiling where heated indoor air sneaks up under the roof. Loose fill slows heat soaking through drywall, yet air pours through an open hole as if the fill were not there.

Attic Ventilation And Baffles

Attic ventilation lets outside air enter at the soffits and leave near the peak, which keeps the attic close to the outdoor temperature and carries moisture away. A cold, dry attic means snow melts less from below, the roof boards stay sound and the insulation stays dry.

Bonus Room Insulation

Bonus room insulation fixes the room that sits over an attached garage and never feels like the rest of the house. That room has a cold garage under its floor, short knee walls with attic space behind them and a sloped ceiling under the roof.
