Considering the fact that over 95% of heat loss in a home occurs through the roof, the importance of loft insulation should not be undermined.
We explore how loft insulation reduces heat loss, and why spray foam offers the most cost-effective solution overall…
Adding insulation to roofs is simple, affordable and the most effective way of reducing heat transfer. So why don’t more people do it?
Perhaps the answer revolves around common misconceptions. Many homeowners mistakenly believe that ample insulation in their loft space equates to adequate retention of heat.Unfortunately, this is usually not the case. Older materials may have functioned effectively in the past but over time, their efficacy is sorely compromised, with lagging and sagging inevitably leading to air leaks.
Air leaks don’t just compromise cosy conditions-they also compromise your fuel costs as well. Indeed, with the persistent price hikes, it’s easy to feel attacked on all fronts.
You can’t control the price the suppliers charge-but you can control the overall price you pay, by reducing your energy usage overall. Loft insulation is one of the best ways of achieving this aim. It has a direct effect on the amount of fuel needed to produce heat.
The benefits are obvious-but how should you start?
Your first port of call should be assessing the accessibility of your loft, as this will determine the most appropriate method for the task at hand.
Let’s take a look at accessibility in a little more detail:
- Accessible lofts are insulated with felt-like insulating material like mineral wool. This material is available on most home-goods stores.
- Inaccessible lofts need loose insulating material that can be blown to loft by an installer.
