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.

Cellulose or fibreglass?

Both work when installed to depth with the ceiling sealed underneath. Cellulose is denser and resists air movement better; fibreglass is lighter and settles less. We pick based on what is already up there and tell you why.

Why does my Lorelei 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.

Do I need to seal before adding insulation?

Yes, and it is the part most often skipped. Warm moist air leaking from the house frosts the roof deck and wets the insulation. Blowing over unsealed pot lights and top plates buries the problem instead of fixing it.

How much will this save me on heating?

We will not put a percentage on it. Too much depends on your air leakage, windows and furnace. We will tell you what depth you have now, what you would have after, and where the leaks are — those we can actually measure.

Attic Insulation Lorelei Edmonton | Attic Top-Up

Attic top-ups in Lorelei that hold their depth

The most common mistake in an Lorelei 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.

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

Why air sealing comes before insulation in Lorelei

Insulation does not stop air

Batt and loose-fill slow heat transfer; neither stops air movement. In an Lorelei 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.

Lorelei drywall in context

About Lorelei

Lorelei is named for castle site on the Rhine in Germany.

What we see in Lorelei

In Lorelei 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.

What we can and cannot tell you about savings

Honest about the number

We will not quote you a percentage off your heating bill. It depends on your current depth, your air leakage, your windows, your furnace and how you heat the house.

What we will say

What the attic has now, what it would have after, and where the leaks are. Those are things we can measure and show you. A savings figure from a contractor who has not seen your utility bills is a sales number, not an estimate.

Storage in the attic and the insulation you lose

Boards over joists compress everything

Where a Lorelei 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.

Ventilation is not optional up there

Cold attic, by design

An Lorelei attic is meant to run close to outdoor temperature so the roof deck stays cold and snow does not melt and refreeze at the eaves.

The failure it prevents

Blocking soffit vents with insulation causes exactly the ice damming people add insulation to prevent. Air sealing the ceiling below and keeping the vents clear are two halves of the same job.

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

Stop and check first

Some older Lorelei 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.

Keeping the eaves clear in an Lorelei 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 Lorelei 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.
