Roughly 35 per cent of all heat loss in a home occurs through the walls.
There are several ways through which this heat loss occurs, the main one being the transfer (leaking out) of internal heat to the external cold (i.e. heat loss from inside a building).
This is what insulation is designed to prevent.
Of course, the reverse happens when the heat is outside, and you want the inside to be cool.
Suntraders have detailed knowledge of the science behind the design of the insulation needed to prevent such a heat transfer, either in summer or winter.
Getting down to basics
There are several ways to insulate a home: using insulation batts and blankets or using blow-in (aka loose-fill) insulation.
Blow-in insulation is blown into attics and wall cavities of existing buildings that were built without insulation, and Suntraders maintains this is a far more effective solution than batts and blankets installed during construction.
What is Suntraders’ aim?
When it comes to home insulation, all competitors in the business aim to stop as much heat transfer as possible, in an environmentally friendly way.
Walls are an essential part of your home’s complete thermal envelope, which is supported by the fact that insulation in walls is mandatory for all new homes.
Currently, the minimum requirement for new homes is a 5-star energy rating. Soon there will be a 6- or 7-star mandatory rating and our loose-fill insulation in walls will play a crucial part in achieving such a high level of energy efficiency.
Assuming your walls have a cavity, blow-in insulation is a relatively simple task.
By comparison, insulation batts are delivered to a construction site with their R-value known, and when all these batts have been installed in your cavity walls, ceilings or the blankets installed on your roof, the expectation is that the building will now have that R-value.
