FAQs

Q – When should existing insulation be removed from the attic?

A – Insulation Removal: the following reasons could result in full or partial removal:

  • moisture in the ceiling – this indicates that your attic floor is not airtight and that potential damage should be further assessed after the insulation is removed
  • you have experienced attic rain
  • outdated insulation should at minimum be removed from the attic edge to allow for premium insulation to reach this vulnerable area
  • your attic has wood chips – this poses a fire hazard and has far less R-Value than current insulating materials
  • there has been an infestation – the damaged insulation and infestation remanence should be removed and the attic sealed airtight before installing ventilation systems and new insulation

Q – How far out are you booking?

A – Service dates are most often booked 1-2 weeks in advance; we can generally accommodate emergency situations within a day or two.

Q – How long does an attic upgrade take?


A – A standard upgrade may take a half day; full removal and re-blow could require 2+ days.

Q – What are current Alberta Building Code Requirements?

A – Alberta building code is approximately R-60 in the attic

  • This equates to 16 inches of blown in cellulose; blown in fibreglass requires even more depth

Definitions

Ice Damming

This refers to ice build-up on your eaves, and the effects can be devastating to your home and wallet.  Ice damming is caused by poor attic insulation and ventilation.  If warm air is permitted to leave your house and enter the attic, and if the warm air stays stagnant in the attic, it can melt the snow on your roof.  The water then drips down your roof and freezes upon contact with eaves and cold air.  The resulting icicles gradually melt as the weather warms potentially destroying your roof, insulation, exterior paint, interior drywall, and eaves.

Shingle Curling

If your shingles are near the end of their manufactured suggested life, it could be due to age.  But often, premature breakdown of shingles is caused by inadequate airflow in the attic.  The hot summer air becomes trapped in the uncirculated attic, and then reaches unfathomable temperatures.  This undoubtably roasts and destroys your shingles.

Attic Rain

This most often occurs in energy efficient homes that have neglected the attic.  When the home is completely sealed with new doors and windows, the humidity has no where to escape except through the attic.  In the winter, the humidity enters the attic and turns to frost on the attic ceiling.  When the weather gets warmer, the frost melts and starts “raining” from the attic ceiling into the insulation and possibly into the home.  This can cause massive damage to the ceiling and fixtures.  The attic floor, all fixtures, and hatch must be sealed airtight and insulated to prevent attic rain and its devastating effects.

Net Zero Home

The annual energy consumed is equal to the energy generated; in so far as insulation is concerned, the home must pass an air tightness test at the required level to be considered “Net Zero.”
