Why Spray Foam Insulation Is Superior To Fibreglass Insulation
If you’re wondering which material is better for insulation, here are 8 reasons why Polar Spray Foam Insulation is vastly superior to fibreglass insulation:
Spray Foam Insulation is Stronger
After fully expanding, spray foam solidifies into a sturdy material that is extremely damage-resistant. In contrast, uncovered fibreglass or cellulose can be easily damaged by house pets, kids, or workers resulting to degraded or inefficient insulation.
Polar Spray Foam is Safer to Use
Polar spray or pour fill insulation foams are 100 percent water-blown and do not contain synthetic blowing agents or harmful substances like HCFCs, HFAs, HFCs and formaldehyde. Most fibreglass, on the other hand, contain formaldehyde and will likely release formaldehyde emissions into your home.
Fibreglass Lets in Water
The problem with fibreglass and cellulose insulation is that these materials do not prevent water from penetrating the wall. In fact, cellulose, which is basically shredded paper, absorbs water and this can result to permanent damage to insulation or to mold proliferation. Foam insulation, in comparison, either repels water or drains it, as in the case of open cell foam insulation.
Spray Foam Insulation Represents Advanced Technology
Fibreglass and cellulose (shredded paper) are remnants of earlier insulation technology that’s inefficient by today’s standards. Foam insulation had evolved these last 25 years through constant application and testing to become the cutting edge solution to today’s insulation needs.
Spray Foam Keeps Away Pests
Spray foam insulation will expand and coalesce into a solid material that common house pests like termites, rodents, or cockroaches cannot penetrate or break down to be used for nesting, as is often the case with cellulose and fibreglass.
Spray Foam is Firmly Fixed
Spray foam after it expands and solidifies, will always remain in position and will never subside, bend, or flop. It will not gradually disintegrate and produce dust in the process like fibreglass and cellulose. These obsolete insulation materials will also sag and settle over time creating openings through which dust and other pollutants will penetrate the house.
Spray Foam Leaves No Gaps
The thing about cellulose and fibreglass is that these materials are often very hard to fit in completely, leaving cracks and holes through which air or moisture passes freely. Spray foam expands and seals all holes and fissures providing airtight insulation.
Polar Spray Foam Provides Airtight Insulation
Because it expands and fills all void and cavity, spray foam insulation effectively stops airflow. Heated air often flows out of the house through gaps in fibreglass insulation, just as cold air from the outside can also penetrate the house. This results in a constant heat loss and can mean high energy costs to the homeowner.
