Types of Insulation Roofing
Insulation on roofs can also make homes more energy efficient, saving heat during winter and heat during summer as well as saving you money on energy. You will discover different types of insulation you can use in your home like spray foam or rigid boards.
These are high-density materials and fire, weather, mold and insect-resistant. Because they come as rolls, they can be cut to size as needed.
Fiberglass batts
This is one of the insulation choices in your house, fiberglass batt insulation. Fibreglass batt insulation is the go-to choice thanks to the precut size that makes installation easy and the price. And unfortunately fiberglass irritates eyes and skin so the person who installs or works with it should wear protective clothing; it’s also an airborne respiratory irritant so be careful where you install it or work with it at all.
Fiberglass insulation saves energy in every home. But a badly installed one could have gaps that allow heat to pass through and compromise its performance – causing it to grow mould and mildew. Hence you must hire professional assistance for installation as per building regulations and energy efficiency.
Spray foam
Spray foam insulation replaces fiberglass insulation. You can put it on top of roof tiles, concrete, or with holes punched in wall cavities. Often times spray foam will also be installed alongside an elastomeric roof coating for a long-lasting green system.
Air sealant is a two-part liquid applied with specialized tools that expands to fill small gaps or openings and create an airtight seal that stops air leakage and saves on energy and expenses. Moreover, it has a very strong material which will not allow mould, mildew, rot growth, and ants.
Spray foam insulation is a cost effective and energy efficient insulation product that makes the investment by saving you money. But proper installation requires expert installers trained in its use to ensure even coverage and thickness so that there are no energy wasting gaps, and your energy savings can be the most effective.
Gypsum cover boards
Gypsum insulation boards (often called cover boards or insulation boarding) are an affordable and robust option for many conventional low-slop roof systems that will keep membranes safe from foot traffic and equipment penetration, while adding fire resistance and insulation.
Boards for Dens-Deck fiberglass mat face gypsum core cover have an ultra-high PSI rating and are resistant to water, mold and fire. Their uniform substrate allows material compatibility with waterproof roof membranes and improves adhesion for adhered and fully-adhered single-ply installation.
These cover boards meet R-value requirements with HD polyiso insulation like Hunter Panels’ H-Shield HD polyiso insulation, but they will have less R-value than polyiso. Gypsum board cannot be the only solution to R-value and cannot be trusted as insulation material on its own.
Perlite
The lightweight structure of Perlite also means it is a low-cost option for roof reroofing because it offers superior energy and comfort characteristics to natural insulation products like wool or polystyrene foam. What’s more, perlite stays in insulation quality long after a building has been installed, which enhances energy efficiency and indoor comfort.
Perlite is added to lightweight insulating concrete to reduce weight and be a thermal insulator and as an insulator to LPG tanks and tank containers to retain the extremely low temperatures required to freeze this liquid.
Perlite is not just insulation, perlite is fire resistant at construction sites, thanks to its Class A1 fire rating – so building occupants are safe in the event of an emergency. Furthermore, perlite is chemical resistant and odourless, a cleaner alternative to chemical insulation products that have damaging effects.
Fiber cement cover boards
Fiber cement cover boards can be used for insulation roofs and they are easy to install. The come in a variety of colors and styles, they are lightweight and durable, so they can be easily installed. They also easily mount on wood or steel supports.
They are less prone to mold, mildew and water than gypsum board. And they’re less vulnerable to fire. And they last longer than drywall.
These boards are often used as substrates, heat insulation and coverboards for commercial roof surfaces. You can also use them on parapet walls. Their fire ratings are UL Class 1 and A certified, moisture, mildew, and mold resistant and ASHRAE 52.2 compliant for unlimited slope installations.
