Attic hatch insulation turns a thin, drafty access lid into part of the insulated ceiling. We gasket the frame and glue a thick stack of foam board onto the lid, so the hatch holds heat like the attic around it.

Most hatches in Newmarket houses are a plain square of drywall or plywood resting on a trim ledge. Left as is, there is nothing on top and no seal at the edge, so heat leaks through it every winter day.

Attic Hatch Insulation details

What Attic Hatch Insulation Includes

Attic hatch insulation starts with foam gasket tape around the ledge, so the lid seals shut. Layers of rigid foam board are glued to the top of the lid, bringing it close to the R-value of the surrounding fill. A plywood dam around the opening stops loose insulation from tumbling down whenever you open the hatch.

You still get a hatch that lifts easily, minus the shower of fill.

Pull-Down Attic Stairs Need Attic Hatch Insulation Too

Folding stairs leave a bigger opening with gaps around the whole frame. Attic hatch insulation for stairs uses an insulated cover that sits over the stairwell from the attic side, plus a gasket around the frame below. Few jobs take the chill out of a hallway faster.

Attic Hatch Insulation Is Part Of Every Top-Up

Once the attic reaches R-60, the hatch has to keep up. Attic hatch insulation is part of every attic insulation top-up and every job using blown-in cellulose insulation, so the opening never becomes a cold patch in a deep attic.

Attic Hatch Insulation Price

Attic hatch insulation by itself usually runs $150 to $450, depending on the hatch size and whether it is a plain lid or a set of folding stairs. Most of our top-up prices already include it.

Jobs That Often Share The Same Visit

Sealing, the hatch and a top-up tend to share one install day, which spares you a second visit.

  1. Deep grey blown-in insulation reaching the rafters along the eaves of an attic

    Attic Insulation Top-Up

    An attic insulation top-up keeps your existing fill and blows a fresh layer over it until the attic reads R-60. Our two depth readings record exactly how many inches went on.

  2. Grey blown cellulose spread across an attic floor, with light coming through the soffit vents

    Cellulose Insulation

    Cellulose insulation starts life as newsprint and cardboard, shredded and treated so it resists fire and pests, and we blow it across the attic floor as loose fill. Because it tucks in around wiring, nails and truss webs, cellulose insulation is the material we pick most often for older attics.

  3. Thick white blown-in fiberglass across an attic, lit by a gable window

    Blown-In Fiberglass Attic Insulation

    Blown-in fiberglass insulation arrives as fluffy spun glass that the hose lays down in a soft, even blanket. It will not soak up water, puts very little weight on the ceiling and holds its depth for years.

  4. Vacuum hose nozzle lifting old cellulose insulation out of a joist bay

    Attic Insulation Removal And Replacement

    Attic insulation removal clears out fill that is damp, mouldy, fouled by mice or squirrels, or crushed past saving. With the joists bare and the ceiling sealed, new attic insulation is blown back in to full depth.

  5. White insulation pouring from a blowing hose onto an attic floor under the rafters

    Attic Air Sealing

    Attic air sealing shuts the small openings where heated house air pours up into the attic, with spray foam, caulk and fitted covers. We do it before any new attic insulation goes down, since insulation slows heat yet lets moving air straight through.

  6. Dark water stain on attic roof boards above damp, matted cellulose insulation

    Ice Dam Prevention

    Ice dam prevention aims to hold the roof deck at outdoor temperature, so high snow stays frozen instead of melting and refreezing at the eaves. In practice that means sealing the ceiling, keeping soffit air moving and bringing the attic insulation to full depth.

  7. Old, thin cellulose insulation lying on an attic floor under bare roof framing

    Attic Insulation Rebate

    A Newmarket owner whose thin attic is brought up to R-50 may qualify for an attic insulation rebate under Home Renovation Savings, the province-wide program run jointly by Save on Energy and Enbridge Gas. The thinner the attic was, the larger the attic insulation rebate.

  8. Pink fiberglass batts laid between joists across a wide, lit attic

    Attic Insulation Cost

    Four things drive attic insulation cost in Newmarket: how big the attic is, which material you pick, how many inches are already up there, and whether a clear-out comes first. Most homes pay between $1,500 and $3,500.
