There is a wide variety of insulation material for roof available on the market. These materials are designed to meet specific requirements like thermal resistance, moisture protection and cost-effectiveness. Insulation for the roof is a crucial component of your home’s structure and it helps to save energy by reducing winter heat loss and summer heat gain. There are many different types of insulation for the roof, including loose-fill, spray foam and rigid boards. Each type of insulation for the roof has different R-values, which indicates its thermal resistance.

Spray foam insulation has a high R-value and provides air-sealing properties that minimize the risk of condensation, mould or rot. This product is highly suited for a roof because it can be applied to the entire surface area. It is also easy to install and can be cut to fit nooks, crannies and corners of the roof.

Choosing the Right Insulation Material for Your Roof: A Guide

Foam board insulation is a versatile option for your roof because it comes in standard sheets that can be cut to fit any space. It is available in a range of thicknesses and has a reflective foil on one side that reduces radiant heat. There are three types of foam board insulation: extruded polystyrene (XPS), expanded polystyrene (EPS) and polyisocyanurate (Polyiso). Each type has its own unique characteristics, but all have a high R-value and are moisture-resistant.

Other options for your roof include gypsum cover board, which has a low R-value and should be used in combination with other insulation products. Cellulose insulation is made from recycled paper and can be bought in rolls or in loose-fill form. Rockwool is a non-toxic and environmentally friendly insulation product, while perlite has been in production since the 1950s and is an economical choice for flat roofs.
