This barrier prevents heat escaping in the winter and ensures that your building remains cool in the summer.

There are many different types of insulation, but the golden rule is: the more there is, the better it works.

Whats so great about insulation?

• the single most effective way of improving energy efficiency
• 35% of heat in a house is lost through uninsulated walls and 25% through roofs
• it’s cheap, so has one of the shortest payback periods
• it’s hidden, so doesn’t get in your way
• you can put insulation on the inside or the outside of your building
• keeps sounds out - great in noisy towns and cities
• putting it in your loft is easy and immediately makes your home cheaper to heat
• you can install some types of insulation for free using a government grant
