Energy Upgrades-The Three Step Process

  • 1. Air Sealing

    Electrical and plumbing penetrations through the attic floor or ceiling allow heat and moisture to escape from the house interior into the attic. These areas must be properly air sealed to prevent heat and moisture entering the attic. Kitchen and washroom fans require air sealing and proper ducting to the exterior.
    Bulkheads above bathtubs and cupboards are often open to lower wall framing and allow air currents to infiltrate the attic; these require insulating.

  • 2. Ventilation

    A balanced ventilation system should be installed allowing intake air at the eaves or soffits and exhaust air at the roof vents. In the summer, introducing air into the attic ensures adequate ventilation thereby reducing heat transfer into the home and extending the life of the shingles by keeping them cool. During the winter ventilation helps prevent moisture build up which can produce wood rot, mildew and poor air quality. Adequate ventilation and insulation can reduce the risk of ice damming and subsequent damage from water back-up.

  • 3. Insulation

    Energy audits recommend a minimum of R50 in the attic. Cellulose Fibre insulation is a first-rate insulator which fills all crevices and voids and can be blown in over existing insulation. At the proper density Cellulose Fibre does not settle and has a high R-per-inch value. It is fire resistant and protects against fungal growth, insects, rodents and wood rot. Insulation must be blown in from the attic interior to ensure that all crevices are filled and the insulation attains the right density.

    Cellulose insulation is a superior product and it offers much more than fibreglass or mineral coarse-fibred insulation such as:

    • An environmentally safe product – it’s made from recycled material, uses NO pollutants during manufacturing and promotes an environmentally friendly community
    • Better “R-per-inch” values
    • Greatly reduced air leakage
    • Greatly reduced convective heat loss
    • A cost effective solution that fits all construction budgets
    • Suitable for new construction or retrofits
    • No known associated health risks
    • Fire retardant

    Climatizer Plus has been extensively researched and field tested. It is approved by the Canadian General Standards Board (CGSB), the Canadian Construction Material Council (CCMC), the National Research Council (NRC), the National Building Code (NBC), the Underwriters
