BIBS (Blow-In-Blanket System) is a state of the art, environmentally friendly, custom fit insulation process utilizing specially manufactured fibreglass blowing wools that are installed by certified professionals.
The process was developed in 1983 in the USA, since then thousands and thousands of homes across Canada and the USA have been insulated using BIBS.

Ideal applications for BIBS are; sidewalls, sloped ceilings, and floor cavities.  The insulation is blown through a hose and out a nozzle into the cavity behind a polypropylene mesh that is attached to the face of the studs, trusses, rafters or joists.

The Blow-In-Blanket System works with any blueprint, fits any configuration. Cavities.  Curves. Vaulted ceilings. Crawl spaces. Custom windows.  Rim-joists.  BIBS is a proven, time-tested, premium insulation that fits any configuration, any custom situation, any size home.  It blows in easily, fills completely and lasts for the life of the home.

BIBS is safe, clean, fast and effective.  It's also fire-resistant, moisture-resistant, and does not attract or act as sustenance for animals. BIBS uses non-combustible fibreglass and there are no chemicals or noxious odours over time.  The installation is clean as the mesh contains most of the fibres. The fibres are pure fibreglass with a texture like cotton so it is not itchy like most fibreglass batts.
BIBS Doesn't Settle

With BIBS you can rest assured that your insulation will last the lifetime of your home. Unlike other types of blown insulation, BIBS won't settle from gravitational forces or household vibrations such as slamming doors.  Extensive testing has been completed to confirm that BIBS doesn't settle.  Under CCMC Evaluation report 11790-R, after a simulated drop test (60 times from a height of 2.5cm) there was no settlement.  In thousands of Ontario homes insulated using BIBS there has not been 1 report of settling.

If conventional insulation is not properly installed in cathedral ceilings, or if the insulation settles over time then gaps and voids are created, which provides a path for expensive heat to escape.  In the winter this can cause ice dams to form which may lead to decreased roof life, as well as potential damage to the interior of the home.  With BIBS a special cardboard insert is installed to create a constant ventilation channel between the roof sheeting and the insulation.  The depth of the cardboard inserts can be adjusted to achieve the desired R-value.  The insulation is blown in at sufficient density to ensure settling and shifting will not occur, eliminating heat loss through gaps and voids.

The most difficult areas to insulate properly with conventional batt insulation are around electrical boxes, wiring and pipes.  Ultimately these areas result in gaps, voids and/or compressed batts.  The Blow-In-Blanket System fills tightly around all piping and wiring, eliminating gaps and voids that allow cold air to enter and warm air to escape.  Tests show that an R20 batt with a  mere 6% void area in the cavity performs at only R12.5 on a cold day.  That is 36 ½% below the stated R-value of the batt insulation.  During the same test BIBS performed at a minimum of R22.7.

Batts are manufactured to a width of 15”, and are installed into a cavity that is 14-½” wide.  Pushing the batt into the cavity causes it to arch at the back, creating a void area that allows convective air currents within the cavity.
Additionally, batts are manufactured to precise dimensions in a factory environment, but houses are typically site built and inevitably have variation in cavity size.  Studies have shown that up to 60% of stud cavities in a new home are non-standard size or contain wires, pipes, electrical boxes or other obstructions.  In these situations it is very difficult, if not impossible to get a batt to fit well, and the result is air gaps and/or compression of the batt which reduces the insulation value.  BIBS produces a seamless blanket of insulation, regardless of the shape or size of the cavity.  This ensures uniform R-value throughout the entire cavity and reduces air infiltration.

BIBS installers are trained and certified to provide the highest quality workmanship.  Regular re-certification is required and only qualified contractors may install and market the Blow-In-Blanket System.  Regular testing throughout the installation is done to ensure the correct density of the final product thereby ensuring the specified R-value.

BIBS R-Value Data:

BIBS Provides Superior Sound Control:

In addition to thermal insulation, BIBS is well suited for interior walls and floors where sound control is desired.  Acoustical tests done on products used in the Blow-In-Blanket System proved that sound attenuation for BIBS is 4 1/2 times better than that of batt
