Insulation

Surprisingly quick and easy to install, loft insulation is one of the most effective steps you can take to make your home more energy-efficient and bring down your bills. In fact, if every UK household fitted it to the recommended thickness, it would save enough energy to heat 750,000 homes each year.  Building regulation now states every new roof should come with insulation.

How much insulation do you need?

Most homes have some insulation, but it might not be as effective as it could be. Although loft floors should have at least 270mm insulation, there’s often as little as 25mm – particularly in older houses. Also, existing insulation can sometimes be compressed by storage boards laid over the top, which makes it much less effective.

You can easily top up your insulation by using different thicknesses and widths that are designed to be laid between and on top of joists. But if you want to be able to walk around your loft or store boxes there, you’ll need to lay solid polystyrene board insulation on top of the insulated joists, and secure chipboard loft boards on top.
