Attic Insulation Removal
Common Types of Insulation
Fiberglass
The “pink cotton candy stuff” you probably know it as
Easy instalment by a professional
Non-flammable
R-value = 3.0-3.7 per inch
Mineral Fiber
Easy instalment by a professional
R-value = 2.8-3.7 per inch
Good fire resistance and sound-proofing abilities
Cellulose
Mostly used in attics
One of the eco-friendliest forms of insulation since cellulose is made from recycled cardboard, paper, and similar material
One of the most fire-resistant types of insulation
Highly recommended that it is installed by a professional as it can be difficult to install properly
Polystyrene/Strofoam
R-value = 4.5-5.0 per inch
Water and sound resistant
Need to be covered with a chemical coating called Hexabromocyclododecane (HBCD) to make it fire resistant
Highly recommended that it is installed by a professional as it can be difficult to install properly
Polyurethane Foam

FAQ
Why should you insulate your house?
Keep house warm in winter and cool in summer
Lower energy bill
Prevent mold growth
Keep unwanted noise out
What does insulation do?
Keep outdoor air from getting inside your home and conditioned air from escaping
CMHC website states: “A wool sweater will keep you warm if the wind is not blowing and it is not raining. On a windy, rainy day, wearing a nylon shell over your wool sweater helps keep you reasonably dry and warm. A house is similar. On the outside, underneath the brick or siding, there is an air barrier that does the same thing as the nylon — it keeps the wind from blowing through. Then there is the insulation (like your sweater) and a vapour barrier, which helps keep moisture away from the house structure where it can do damage.”
How is insulation rated?
Insulation is rated based on how resistant the material is to the movement of heat, commonly referred to as the R-value; the higher the R-value, the more effective the insulation is.
To use the maximum benefits of insulation, make sure to hire a professional to insulate your house as improper installment can lower the R-value of the material used.
How do you know your home is poorly insulated?
If your walls and floor are cold in the winter and hot during the summer, if you are experiencing mold growth, if you have excessively high energy bills, or if you have uneven and effecting heating/cooling in your home, your house might be poorly insulated.
