4 Popular Types Of Roof Insulation For Residential Properties

Roof insulation helps to regulate the temperature in your home throughout the year. During colder months, insulation will lessen the amount of heat lost through your roof; while in the summer months, insulation can deflect heat from the sun and help keep your home cooler. Some types of insulation can also provide a degree of soundproofing and can reduce condensation build-up. There are several types of insulation that are suitable for use on residential roofs, but they each offer different pros and cons. Here's an overview of 4 popular types of roof insulation:

Glasswool

Glasswool is a highly durable roof insulation material that should last for the lifetime of your property. It's non-combustible and made from recycled material, which makes it a good option for environmentally conscious homeowners. Glasswool is a cost-effective option that can fit into most budgets without compromising on quality, but it does need to be installed by someone experienced in working with glasswool because if the material is compressed during installation its performance will be reduced.

Cellulose

Cellulose insulation is a little cheaper than glasswool and predominantly consists of recycled paper that's treated with a number of chemicals, including boric acid. The chemicals added serve a number of purposes, including increasing the fire resistance of the material and lowering the risk of mould growing if you experience a moisture problem in your home. Cellulose insulation can sag a little over time, but it's still an effective material and it can also deter some insects, which may make it a good choice for you if you're concerned about woodworm infestations in your roof space.

Polyester

Polyester insulation is made from recycled PET plastic, which helps keep plastic out of landfills. However, this material is not fire resistant and can melt when exposed to high temperatures. It's a cheap, durable option that is non-allergenic and easy to install. Polyester insulation can be purchased in batts and rolls.

Mineral wool

Mineral wool is on the higher end of the price spectrum for roof insulation materials. It's made with chalk and basalt rock, and it offers excellent resistance to fire and moisture. Mineral wool is a great choice for those who would benefit from improved soundproofing, as its acoustic performance is higher than any other insulation material used on residential roofs. However, it should be noted that mineral wool can cause skin irritation when being installed.

If you're thinking of having insulation installed in your roof, or if you're unsure of whether the current insulation you have is the best option for your home, schedule a roof survey with your local roof insulation service.
