insulation for roof is an important step in lowering your home’s energy costs. It prevents warm air from escaping in cold regions and keeps hot air in in hot ones, thus reducing the need to use heating or cooling appliances. It also helps reduce outside noise.

There are several different types of insulation for your roof. Choosing the right one depends on your location and the type of building you live in. The best choice is an ENERGY STAR-approved product that matches your region’s climate. In addition, the product should be fire-resistant and not absorb moisture to avoid wood damage.

Polystyrene or extruded polystyrene (XPS) insulation roll is the least expensive of all options, but it may not be a good choice for your house due to its high water vapour permeability. Polyisocyanurate or spray foam insulation is an excellent option if you have a low-slope roof. It has a high R-Value and resists moisture better than polystyrene.

Insulation for Roof: Enhancing Comfort and Energy Efficiency

Loose-fill or blown-in insulation is made of fiberglass, mineral wool or cellulose. This is blown into the attic space using machinery. It has a high R-Value, and can fill in hard to reach areas. It can also be blown between the ceiling joists to fill gaps, though it must be covered with a fire-rated material.

Rigid board insulation is another option, but it has a lower R-Value and can be expensive. Structural insulated panels (SIPs) have insulation sandwiched between plywood and offer extra structural support.
