Do you insulate the attic hatch too?

Yes. It is a direct opening between the house and a space at outdoor temperature, and it is usually the first place we look when someone says a hallway or landing is cold.

Do you insulate over an addition or a vaulted ceiling?

Those need looking at specifically rather than quoting an average depth. Shallow attics, cathedral sections and knee walls are usually the coldest rooms in an Greenfield house and the parts a general top-up misses.

Why is the area above my exterior walls always cold?

Geometry. The roof meets the wall at the lowest point in the attic, so there is least room exactly where it is needed most. Baffles hold insulation back from the soffit vents while letting depth carry over the wall plate.

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.

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.

Attic Insulation Greenfield Edmonton | Attic Top-Up

Attic top-ups in Greenfield that hold their depth

The most common mistake in an Greenfield 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.

Air sealing at pot lights, top plates and the attic hatch
Depth markers left in place so the result is verifiable
Existing insulation levelled before the top-up
Baffles kept clear so the soffit vents still breathe
Attic hatch insulated and weatherstripped
Blown-in loose-fill to the depth your permit specifies

The eaves are where it goes thin

Geometry works against you

The roof meets the wall at the lowest point in the attic, so there is least room for insulation exactly where the wall below needs it most.

What it needs

Baffles that hold the insulation back from the soffit vents while still letting depth carry out over the wall plate. Skipping them in an Greenfield attic either blocks the venting or leaves a cold band above every exterior wall.

Greenfield drywall in context

About Greenfield

This area was named for Herbert Greenfield, leader of the United Farmers Party and Premier of Alberta from 1921 to 1925.

What we see in Greenfield

In Greenfield 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.

Adding to what is already there

You rarely start empty

Most Greenfield attics already have something, whether old batts, older loose fill, or both in layers.

When to top up and when not

If the existing material is dry, even and uncontaminated, adding over it is usually the best value. If it is wet, compacted, rodent-affected or hiding unsealed penetrations, removing it first is worth the cost, and we say which one we found.

Pot lights, and which ones can be covered

Not all fixtures are equal

Older recessed fixtures in Greenfield 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.

Sealing the ceiling below first

The order that matters

Warm moist air leaking from the house into a cold Greenfield 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.

Insulating a Greenfield attic with knob-and-tube or old wiring

Stop and check first

Some older Greenfield homes still carry active knob-and-tube wiring in the attic. Burying it in insulation is not something we do — it needs an electrician to assess and usually to replace before the attic is filled.

Why we raise it

It is the kind of thing found halfway through a job, and it is far cheaper to find at the quote. If we see it, we tell you and we stop until it is dealt with.

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 Greenfield 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.
