Insulation options explained

Adding insulation to a home ready for winter doesn't seem a main priority during the summer months, but as the old proverb says, 'make hay while the sun shines', so getting the job done now will ensure your home is heat tight as soon as the colder weather arrives. 

In this article we take a look at the different types of insulation available. 

Cavity wall insulation

Warmth escaping through walls is one of the major heat losses in a home so adding cavity wall insulation can really help to trap heat and reduce yearly energy bills. 

A cavity wall is made up of two walls with a gap between. In the majority of homes built after 1990, the gap between the two walls would have been filled with insulation to help stop heat escaping when it was built. However, if you have cavity walls and your home was built prior to 1990, it is possible to retrofit the insulation.

It's relatively simple for an experienced installer to do – it's not a job you can do yourself. Small holes will be drilled at intervals on the outside walls of your home, then insulation will be blown into the cavity through the hole.  

Once all the insulation is added, the holes will be filled and won't be noticeable.

Loft and roof insulation

As heat rises, the roof is where your home could lose a quarter of its heat so having adequate insulation is vital.  Insulation should be laid between the joists then, if you're planning to use your attic space for storage, boards laid over the top. 

For a loft that is being used as an extra room, you will need to add insulation between the rafters as well – this typically comes on boards that can be cut to size – then covered with plasterboards.  Whether you are adding insulation between the joists, or joists and rafters, it is something that can be done yourself and you'll find everything you need at your local builders merchant.  

Underfloor insulation

Newer homes will tend to have concrete floors, so underfloor insulation is not something that needs to be considered, however for those with timber floors it can be retrofitted. For competent DIYers it is something that can be done themselves, as it just means taking up the floorboards, laying the right insulation between the joists and relaying the floor. However, it will need to comply to building regulations which will be your responsibility if doing it yourself. 

If you don't want to go as far as laying insulation under your floor, you can help to cut down on draughts by using a sealant to block any gaps between the floor and skirting boards.
