Regular readers of our blog will by now be familiar with our handy A to Z offering weekly tips about all things technical relating to loft conversions. We’re now on to the letter ‘I’ and nothing quite fits the bill like insulation.
It is really important to make sure that your loft is insulated properly in order to keep the room warm and minimise overall heat loss from the house, meaning that your heating bills should not dramatically increase.
So here is your guide to insulating your loft conversion.
Why bother with loft insulation?
You may be wondering if it is really necessary to insulate your loft. You’ll no doubt be aware that heat rises. That means that should you choose not to insulate your loft, you may lose 25 per cent of your heat through the roof – and that is an awful lot of heat to lose.
So if you’re hoping to keep your energy bills low, make sure you insulate your loft. Good quality loft insulation lasts for a minimum of 40 years so over time, you’ll find that it pays for itself easily.
How to choose the right loft insulation
- If you have regular joists
The best type of insulation to use in this case would be rolls of mineral wool insulation. It’s a fairly easy job that you can do yourself should you wish. Simply layer the first piece between the joists and then position the next layer in a criss-crossed fashion until the joists are completely covered. If you don’t feel confident about doing the job yourself, you can always ask a professional installer to do it.
- If you’ll be using the loft as living space
For this purpose, you’ll need to ensure that boards are put down over the joists which remove the possibility of insulating on top of the joists themselves. To make sure that you have enough loft insulation, it’s a good idea to purchase insulation board that is already fixed to the floor boarding. Alternatively, you can raise the floor level, allowing you to fit in more mineral wool.
And of course, you could always insulate the roof instead of the floor. Do this by positioning rigid insulation boards between the roof rafters, ensuring that the boards fit snugly. Use the highest performance insulation board possible in order to fully insulate your loft.
- If you have a flat roof
For a flat roof, it is preferable to insulate from above. Attach a layer of rigid insulation board over the roof’s weatherproof layer. Should you choose to insulate from underneath, you may find that it leads to condensation problems and you don’t want to risk a damp loft, particularly if you’re going to be using it as living space or for storage.
