Roof Insulation: Types, Application & Installation Procedure

A well-designed and well-insulated home provide you year-round comfort while cutting the cooling and heating bills up to 40%. This, in turn, help reduce greenhouse gas emissions. Insulation also helps in weatherproofing and eliminate the moisture problems. The best time to install it economically is during the construction process. If you are considering to install a pitched roof in your home, then with the help of a Pitched roof insulation board you can do it effectively. Let's know more about it.   

Pitched roof insulation types and their applications: 

• Bulk insulation: Mainly used to resist the flow of the conducted and convected heat. It traps air within its structure. Generally, its thermal resistance remains the same regardless of the direction of flow of the heat through it. It includes materials like cellulose fiber, glass wool, polyester and polystyrene. And, all the insulation products come with one R-value for a given thickness.

• Reflective insulation: It's having high reflectivity and low emissivity that offers a strong resistance to the radiant heat flow. Its thermal resistance varies with the direction of heat flow through it. Usually available in concertina-type batts and multi-cell batts. The combo of these products are known as RFL(reflective foil laminates). 

Where to install? 

You can install the insulation under the roofing material in order to reduce the radiant heat gain. 

Benefits of pitched roof: 

•    ♦ Can be easily installed and it is more efficient

•    ♦ Prevents the vapor drive, which causes moisture problem

•    ♦ Provide more storage space

•    ♦ These have a 40% longer life as compared to the flat roofs

•    ♦ Very economical, as these are about 10-20% less expensive than the flat roofs

The higher is the R-value, the higher is the level of Loft insulation. To know the insulating ability of the available products, you should look at their R-value to measure its resistance to heat flow. Except the R-value, also check out for the price per square meter and whether it can be DIY or need professional help.
