Roof Insulation Types

A roof insulation types will reduce your energy costs by regulating indoor temperatures and reducing the need for constant heating and air conditioning. It will also help to reduce moisture problems such as condensation and mold.

Different insulation materials provide varying levels of energy efficiency, and the best choice will be dependent on factors such as your budget, your climate and the existing architecture. To determine what type of insulation is suitable for your roof, consider its R-value or resistance to heat flow.

Rigid insulation types include gypsum board, wood fiber, perlite and polyisocyanurate foam. The latter is made of recycled plastic waste such as used phone books and is a very lightweight insulation that can be sawn to size with a handsaw. This insulation is also damp-proof and can be attached to the ceiling joists or rafters, making it a good option for use in flat roofs.

Fiberglass insulation is a cost-effective and popular option that can be purchased in fiberglass batt blankets, cellulose and loose-fill form. It is a good choice for homes with difficult access to the attic or wall cavities as it can be blown into the space using machinery, and can reach even the smallest nooks and crannies.

Cellulose is made from recycled paper, and is eco-friendly and effective in preventing heat transfer by trapping pockets of air. It is available in a range of R-values, and can be combined with spray foam to provide an energy efficient system that improves structural rigidity and minimizes air leaks.
