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

  • One of the best types of insulation

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.
