Can my home have blown-in insulation? Bungalows, low roofs and vaulted ceilings
Often, yes. A bungalow, split-level or two-storey home can be a candidate for blown-in attic insulation. The space between the ceiling and roof matters more than the number of storeys.
A bungalow can have a roomy attic, a very low roof or a vaulted ceiling. A two-storey home can have an accessible attic too.
A quick guide to what is above you
You can start with what you already see from the rooms and outside the house:
Open attic
Flat ceiling below a pitched roof: there may be an open attic above it. A hatch tells us where to look, not how much working space there is.
Low attic
Shallow roof: the attic may be low, making the outer edges harder to reach.
Vaulted ceiling
Ceiling that slopes with the roof: it may be a vaulted or cathedral assembly, with no open attic to top up.
Ceiling lining cut away to show the insulation above it.
No need to climb inside to work out which one applies.
An open attic: the familiar top-up
Blown-in insulation is often a practical option in an unfinished attic. It creates coverage around the framing and across the attic floor. At TrueFlight, we use Owens Corning PROPINK blown fibreglass.
Existing insulation does not automatically need to come out. Its condition and coverage determine the starting point. Our Calgary insulation-depth guide explains how different materials affect the R-value.
A low roof: improvement may still be possible
Getting a hose through the hatch does not tell us whether the edges can be prepared properly. We first need to identify the accessible areas, the existing coverage and any ventilation limitations.
On some low-pitched roofs, there is not enough room to install baffles from inside. An upgrade may still be possible, but any access limitations or unresolved blocked intake need to be addressed in the plan before more insulation goes in.
A vaulted ceiling: plan the roof and insulation together
There may be no attic floor here; the insulation sits within the roof assembly.
These spaces need a different plan from an ordinary attic top-up. At TrueFlight, our own crew also installs batt insulation, but the right method depends on the roof's construction, available space, ventilation and moisture control.
If your roof is due for replacement, raise the insulation question before the roofing scope is finalised. It can be an opportunity to improve areas that are difficult to reach from inside. NRCan's attic guide explains why these spaces need a different approach.
Split-levels, additions and garages
Split-levels and additions can have separate roof spaces at different heights. One accessible hatch does not tell us about every section.
We also insulate garages, including batt insulation in suitable walls. Tell us whether you want the garage ceiling, walls or both assessed so the quote covers the areas you have in mind.
Reach matters as much as access
On one southwest Calgary job, insulation was much thinner over a bedroom farther from the hatch. Read the cold-bedroom inspection story to see what we found and changed.
When comparing quotes, ask: "Which areas are included, and what happens if part of the attic cannot be reached?"
What is included in the preparation?
Our normal insulation scope includes sealing accessible air leaks, baffles where accessible and needed, and hatch insulation. Any inaccessible areas or work needed before the top-up should be clear in the quote.
Tell us whether your ceilings are flat or sloping and where the hatch is, if you know. A photo from inside the room can help start the conversation.
Or call 403-879-8988. We will explain the options and give you a clear scope and price before you decide.
