Winter is coming and the cozier your home is the better your days will be when the snow starts to fly!
A great roof is your first barrier against the elements, but the insulation and ventilation in your attic is also very important in home comfort.
Insulation plays an important role in the reduction of heat transfer, the process by which air naturally moves from warm areas to cold areas. Insulation acts as a barrier to this process, preventing the escape of warm air through the roof during the cold winter months and similarly impeding warm/hot air from entering the home throughout the heat of the summer. Bottom Line? Homeowners are able to set their thermostats at lower temperatures all year long and reduce utility bills.
In addition to its favourable effect on energy efficiency, proper insulation, in combination with adequate Attic Ventilation, can provide several other benefits like:
Reduced potential for mold formation
Decreased condensation inside the home
Less expansion and contraction of roof deck
Prevention of ice dam formation in the winter
Protecting the integrity/longevity of the shingles
Many homeowners have likely heard the term R-value used in reference to insulation or insulating materials. This number measures resistance, or blocking capacity, to heat flow; therefore, materials with higher R-values have better insulating properties than those with lower ratings. The following dynamics will have an impact on R-values:
Thickness of the insulation
Where it is installed in the home
How well it is installed by roofing contractors
