Insulation is more than just a building material; it is an asset for any home or building in terms of indoor air comfort, structural integrity, and much more. Insulation is important for proper ventilation and heat transfer, which allows our homes to stay cool in the summer and warm in the winter. As for roofing systems, insulation is key to long-term performance and protection.
Continue reading to learn why roof insulation is so important, and what you can do to ensure that your home or building is protected all year long.
Roofing insulation must be installed properly using quality materials for best results. Quality roofing insulation should help to maintain comfortable indoor air climates, thus reducing our energy consumption and monthly utility bills. It also adds a notable level of protection for a property’s structural components, including the roofing materials, all of which increases the life of a roofing system.
Radiant Heat Transfer
In the summertime, roofs can get very hot, especially if they are not within the vicinity of shade. In fact, roofing surfaces can exceed ambient temperatures by 90°F or more. This excess radiant heat ends up being transferred into the living quarters of the home or building. Oftentimes, radiant heat is transferred from the roof to the attic, is why attics are often insulated.
Specialized materials, such as radiant barriers and reflective insulation, are installed in attics in order to reduce radiant heat transfer. These materials work by reflecting the excess radiant heat back towards the roof. As a result, indoor air climates are more comfortable and stable, and energy bills are lower and more consistent.
Insulation Materials and Applications
It is important to hire a professional Indianapolis roofing company to install insulation to an existing roof system. Not only do they retain the proper licensing and resources, they have experience working with all sorts of roofing systems, giving them the knowledge necessary to install the proper type of insulation.
For instance, steep sloped roofs require different insulating materials than low sloped roofs or flat roofs. The most common types of roofing insulation materials include bituminous asphalt, latex and acrylic barriers, non-bituminous coatings (elastomeric coatings), fibered coatings, and polystyrene panels (or rigid foam).
