Comparisons between different types of thermal insulation for roofs can be helpful in making the right choice for the most effective, longest lasting and energy efficient method. Spray foam insulation and Aerolite insulation are two of the best known products for keeping homes and workplaces consistently warm in winter and pleasantly cool in the summer.
These two types of thermal insulation for roofs both have long term benefits, but it’s worth considering any disadvantages as well as making cost comparatives and looking at their long term value.
Aerolite insulation is easy to install and can be made to fit into all corners and hard-to-reach points inside a roof space. Aerolite is also regarded as a great acoustic insulation.
It’s safe to install, because Aerolite does not contain any hazardous chemicals and does not release any toxic emissions. This non-combustible insulation is made from recycled materials and natural minerals from sustainable sources. The main component (80%) of Aerolite insulation is recycled glass.
Aerolite provides acoustic insulation as well as being excellent thermal insulation for roofs. There is 83% less heat penetration through a roof insulated with Aerolite than in a roof with no insulation. Aerolite Roof Insulation is regarded as one of the best Thermal insulation for Roofs.
Energy saving means lower bills for heating and air conditioning, and Aerolite insulation remains effective for more than thirty years.
Spray Foam Insulation
This type of insulation will keep conductive heat inside your building and will also prevent the penetration of too heat from the sun, in months when outdoor temperatures are high. Molecules within the foam each have a reflective surface, so radiant heat is reflected back.
Spray foam insulation creates a tight seal so no air can leak out through a roof space and less heat will escape in winter. The advantage is that it can be used in any size or shape of a building’s roof space, which makes it very effective for draft proofing.
An open attic will be warm and free from drafts, but any foam that is exposed must be protected by an extra layer of thermal barrier. The foam contains a number of hazardous chemicals, which are released through cutting or trimming.
This method of thermal insulation for roofs reduces the amount of condensation from metal on roofs and wall partitions, but it is not recommended for use with some types of asphalt roofing. When the foam is applied to the underside of a roof with a covering known as “hot roof”, it causes a build up of heat that might cause asphalt shingles to deteriorate.
It is estimated that installation of spray foam insulation can save you around 25% of what you would be paying for heating and air conditioning, and that it will last for up to twenty-five years.
Cost Comparatives and Long Term Value
Spray foam insulation and Aerolite insulation provide long lasting energy-saving, so the cost of installation will be recovered long before it needs to be renewed.
There is a bigger financial gain in installing Aerolite insulation, and that is because it adds extra value to your property. Spray foam insulation will reduce the value of building. It’s not an environmentally friendly product and potential buyers can be put off by the possibility of poor air quality in a home or workplace with foam insulation. Foam removal presents a further risk of exposure to toxic chemicals.
When considering the cost of installing thermal insulation for roofs, the long term benefits are more important than the initial investment. It might cost more initially, but Aerolite insulation is safer, greener and longer lasting than foam spray insulation, so it does have greater long term value.
