Blown-in attic insulation in Kernohan, sealed before it is filled

The most common mistake in an Kernohan attic is blowing insulation over an unsealed ceiling. Warm moist air keeps rising through pot lights, top plates and the hatch, and it carries moisture into cold insulation where it condenses. We air-seal the penetrations first, then insulate.

Sealing the ceiling below first

The order that matters

Warm moist air leaking from the house into a cold Kernohan attic is what frosts the underside of the roof deck and wets the insulation.

Where it leaks

The hatch, pot lights, bath fans, plumbing stacks and the top plates of interior walls. Blowing more insulation over unsealed penetrations buries the problem instead of fixing it, so sealing comes first.

Kernohan drywall in context

About Kernohan

Named for an early pioneer farmer who operated a grocery store here in the 1880s and 90s, Kernohan was not annexed until 1961.

What we see in Kernohan

In Kernohan the drywall work is plaster and lath repair, popcorn and stipple ceiling removal, careful patching into original surfaces. We confirm what your home actually needs on site, in writing, before anything starts.

The attic hatch nobody insulates

A hole in the ceiling

An uninsulated, unsealed hatch is a direct opening between the heated house and a cold attic, and it is often the single worst detail in an otherwise good Kernohan ceiling.

Simple fix

An insulated cover with weatherstripping and a dam around the opening so blown insulation does not spill through when it is opened.

Attics over additions and vaulted areas

The awkward spaces

An Kernohan addition often has a shallow attic, a cathedral section or a knee wall, and those areas are where insulation is thinnest and access is worst.

Why they matter disproportionately

They are frequently the coldest rooms in the house, and they are the parts a general top-up misses because the blower cannot reach them. We look at them specifically rather than quoting an average depth across the whole ceiling.

Pot lights, and which ones can be covered

Not all fixtures are equal

Older recessed fixtures in Kernohan ceilings need clearance and cannot be buried. Newer IC-rated fixtures are built to be in contact with insulation.

What we check

We identify what is installed before blowing. Where fixtures cannot be covered, they need boxing or replacing — and each one is also a significant air leak, so they are usually the first thing sealed regardless of type.

Storage in the attic and the insulation you lose

Boards over joists compress everything

Where a Kernohan homeowner has laid plywood across the joists for storage, the insulation beneath is squashed to joist depth. That strip performs at a fraction of the rest of the attic.

Options

Either the storage area is raised on a platform above the finished insulation depth, or it is accepted as a deliberately weaker zone kept as small as possible. What does not work is topping up around it and pretending the platform is not there.

Depth is the whole number

What you are buying

Attic performance is almost entirely a function of settled depth and even coverage. Two attics with the same product can perform very differently.

How we handle it

Depth markers are set before blowing so the result is measurable rather than asserted, and the Kernohan attic is checked at the corners rather than only where the hatch is. An attic that is deep in the middle and thin at the perimeter is the usual finding.

Attic Insulation Kernohan Edmonton: your questions answered

Will insulating my attic stop the ice at my eaves?
Often it helps a great deal, because ice damming is usually escaping heat melting snow that then refreezes over the cold overhang. Air sealing plus even coverage to the eaves lowers the deck temperature, which is the actual cause.
How much insulation should my Kernohan attic have?
The depth comes from what the code asks for on your permit, not from us. What we can tell you is the depth you have now, whether it is even, and whether the eaves and hatch are dealt with — those three often matter more than the last few inches.
Should I block the vents to stop drafts?
No. The attic is meant to run close to outdoor temperature so the roof deck stays cold. Blocking soffit vents causes exactly the ice damming people add insulation to prevent.
Can you just blow on top of what is already there?
Usually yes, if the existing insulation is dry, undisturbed and not contaminated. If it is wet or shows rodent activity it comes out first, because topping over that seals the problem in rather than fixing it.
How much insulation should my attic have?
It is settled depth and even coverage that decide performance, not the product name. We set depth markers before blowing so the result is measurable, and check the corners rather than just the area near the hatch.
I store things in my attic. Can I keep doing that?
Yes, but the plywood squashes the insulation beneath it to joist depth. Either the storage area gets raised on a platform above the finished depth, or it stays as a deliberately weaker zone kept small. We will not top up around it and pretend it is not there.
