The Facts about Contaminated Insulation
Animals living in the walls, roof or attic, can damage or flatten the insulation. This can
dramatically decrease the energy efficiency (R-value) of the insulation. As the R-value is
decreased, your house becomes warmer in the summer and cooler in the winter! The
insulation may also become contaminated and pose significant health risks. Animal feces
is associated with numerous diseases, mould is associated with respiratory diseases and
insects such as fleas, ticks and mites, love to feed on human hosts and spread disease.
These are all serious health concerns!
Squirrels, raccoons, bats and even birds love to use building insulation for their nests that
are located in the walls, attic or other areas of your dwelling. They leave behind urine and
feces which has been linked to an incurable respiratory disease named Histoplasmosis
(aka Darling’s disease). The accumulation of urine and feces over time can cause rot
(structural degradation) and mould to grow and spread in the attic or walls. Mould has
been linked to respiratory problems and to cause allergic reactions.
Contaminated Insulation Removal
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.
