How much insulation should my Rutherford 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.

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.

Why does my Rutherford attic frost up in winter?

Almost always warm moist air leaking up from the house through pot lights, top plates or the hatch, then condensing on cold sheathing. More insulation on its own does not fix it — the leaks have to be sealed first.

Will you block my soffit vents?

No. Baffles hold the insulation back at the eaves so air can still move from the soffits to the ridge. A blocked attic gets damp no matter how much insulation is in it.

How do I know I got the depth I paid for?

We leave depth markers through the attic so the installed depth can be read off by anyone afterwards. Depth is easy to claim and hard to check once the hatch is closed, which is exactly why we mark it.

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.

Attic top-ups in Rutherford that hold their depth

The most common mistake in an Rutherford 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.

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

Why air sealing comes before insulation in Rutherford

Insulation does not stop air

Batt and loose-fill slow heat transfer; neither stops air movement. In an Rutherford attic warm moist household air rises through pot lights, top plates and the hatch, passes straight through the insulation and condenses when it hits the cold deck.

What that looks like later

Frost on the underside of the sheathing in February, then staining on the ceiling in spring. Sealing the penetrations first is the difference between insulation that works and insulation that becomes the problem.

Rutherford drywall in context

About Rutherford

Rutherford takes its name from Alexander Cameron Rutherford (1857-1941) who was the first premier of Alberta.

What we see in Rutherford

In Rutherford the drywall work is first-year settling, basement dev for first owners, Level 5 over builder-grade. We confirm what your home actually needs on site, in writing, before anything starts.

Keeping the eaves clear in an Rutherford attic

Ventilation and insulation are not opposites

An attic needs air moving from the soffits up to the ridge. Blowing loose-fill right into the eaves blocks that path, and a blocked attic gets damp regardless of how much insulation is in it.

Baffles

Baffles hold the insulation back so the soffit vents stay open. In older Rutherford homes they are often missing entirely, which is why the corners look thin — someone deliberately kept the insulation back, or it was never installed to the edge.

Topping up against removing and replacing

Usually a top-up is fine

Old fibreglass in an Rutherford attic that is dry and undisturbed can be levelled and topped up. It still insulates, and removing it is a large cost for a small gain.

When it has to come out

Insulation that is wet, contaminated, or full of rodent activity gets removed rather than buried, because topping over it seals the problem in. We will tell you which of the two you have after looking, not before.

The attic hatch, which everybody forgets

A hole in the ceiling

The hatch in an Rutherford home is often an uninsulated panel sitting in a frame with no weatherstrip. It is a direct opening between the house and a space that is at outdoor temperature.

What we do

The hatch gets insulated on its back face and weatherstripped so it seals when closed. It is a small job that shows up disproportionately in comfort, and it is the first place we look when someone says the hallway is cold.

Depth, and how to check we delivered it

Verifiable rather than assumed

Blown insulation settles, and depth is easy to claim and hard to check once the hatch is closed. We leave depth markers through the Rutherford attic so the installed depth can be read off later by anyone.

Even coverage

Depth is also an average — a deep drift in the middle and thin corners is not the same as an even blanket. Coverage to the edges is what actually reduces heat loss.

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

Stop and check first

Some older Rutherford 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.
