Insulation on roof is one of the most effective ways to save energy and money at home. Efficient insulation helps you to regulate the internal temperature of your building and it also reduces air leakages. This will help you to achieve significant savings on your utility bills. Additionally, a well-insulated roof protects the interior of your building from dampness and moulds.

Several types of insulation are available, so you can choose the best option for your property. It is important to consider your budget constraints, as certain insulation materials have a higher upfront cost than others. You should also look at the long-term maintenance requirements of your chosen material. For example, some insulation types need to be inspected regularly to maintain their effectiveness.

Insulation on Roof: Strategies for Energy Conservation

Blanket insulation involves placing sheets of fiberglass into the attic space. The most popular type of blanket insulation has an R-value of between 2.9 and 3.8 per inch. This type of insulation is not as effective at preventing air leaks, and it can be susceptible to unhealthy mildew and mold growth.

Another common choice is foam boards, which are rigid panels of insulation. These are made from polystyrene, polyisocyanurate or polyurethane, and they can be held in place by timber battens between joists. Some of these boards come with a vapor barrier, which prevents moisture from penetrating the insulation and damaging the structure of your property. For added strength, some of these boards are laminated together with a layer of plywood, gypsum board or perlite.
