Out with the old and in with the new. Your old insulation is probably costing you money. Even worse, it could be a health hazard!

Insulation in your home or workplace may contain contaminated and toxic materials that can pose serious health risks. Animals living in your attic, walls or water leakage can also damage insulation which results in decreased energy efficiency (R-value) and adds to higher energy costs.

Examples of contaminated insulation:

  • animal feces (associated with various diseases)
  • mould (respiratory diseases)
  • fleas, bedbugs and ticks

Examples of toxic insulation:

  • asbestos insulation (associated with various lung diseases)
  • Zonolite-vermiculite (can contain asbestos)

Prior to the 80's, the product Zonolite was used as a popular attic insulation in approximately 35 million homes in North America. Zonolite (vermiculite) material is brownish in color and may contain metallic and gold looking flakes. It has been described as looking like pieces of popcorn.

Extreme air flow in the attic due to high winds, low air pressure systems etc., can disturb the vermiculite / Zonolite in your attic which in turn can release a dangerous form of asbestos fibers into the air. These fibers can then unknowingly move freely within the house and can pose significant health risks as these fibers can become lodged into the lungs if inhaled. The risks to being exposed to these asbestos fibers can further increase during building renovations or repairs. If you suspect that your attic is insulated with vermiculite / Zonolite, avoid going into the attic, as disturbing the insulation can release asbestos fibers into the air and become what is known as friable.

Notice:  Health Canada advises to NEVER attempt the removal of asbestos-contaminated insulation yourself but to consult a qualified insulation removal contractor, also known as “asbestos abatement”. Inso-Tec also offers air quality sampling and testing, which includes testing for vermiculite / Zonolite in your insulation and attic.

If vermiculite / Zonolite or asbestos is found to be in your home, the contaminated insulation can be removed from the outside of the home keeping all the contamination outside the family dwelling. Maxi-Vents are usually installed in the roof to allow entrance for the vacuum hoses and to promote maximum air ventilation in the future.

Inso-Tec uses a state of the art, 3 stage HEPA filtration negative air system. This vacuum system removes 99.97 % of the mould, dust, gases and fine particulates from within the sealed environment.

Once all the contaminated insulation is removed, soffit airflow vents are installed and vent pipes, light boxes, bathroom fans etc. are caulked and sealed.

Next, Inso-Tec applies "CP-240 Post Removal / Decontamination Sealer" which seals in any remaining off-gases or harmful substances. A skirt is then built around the trapdoor which is sealed and insulated. In the event a vapor barrier has never been put into place, Inso-Tec sprays 1-2 inches of urethane foam insulation that acts as a superior vapor barrier with an additional R-Value of 14.

Once the sealant has been applied, 15" of environmentally friendly cellulose insulation with an R-Value of 50 can now be blown into the attic. Cellulose insulation is rodent, insect and fire retardant and possesses superior thermal and acoustical qualities.

Blown in cellulose coats within cavities where traditional forms of insulation often miss. Corners, crevices, irregular angles and cramped spaces are no challenge for this insulation material.
