Insulation

A comfortable home is important to us all.

Adding insulation to your home is the simplest and most well-known means of improving comfort and warmth in your home.

A house with poor insulation draws in heat in the summer, and seeps out heat in the winter.

This often means relying on artificial means of heating and cooling, which uses lots of energy and costs you money.

 

How does it work?

Insulation acts as a barrier to heat loss and heat gain in specific areas of your home: the roof, the walls and underneath the floor.

The main types of insulation are bulk, reflective and foam. The insulation you choose will depend on the local climate and the area of your home which you’re planning to insulate.

We tested out the artificial heating needed in a house with poor insulation, and in a house with substantial insulation. Our results show that to maintain an inside temperature of 23˚C, you would need to continuously run a heater at 8.9kW in an uninsulated house, and at 1.9kW in an insulated house.

That’s a heating reduction of 79%, and a big saving on your heating bill.

Why insulate?

  • A properly insulated home means less reliance on artificial heating and cooling
  • This means you’ll experience a reduction of up to 50% in heating and cooling expenses
  • A well-insulated home is a more comfortable home.
  • Insulation has a long life and is low maintenance, meaning less hassle for you in the long term
  • Insulating your home properly will eliminate drafts
  • Your home will be quieter due to the sound absorption insulation provides

How do you insulate existing walls?

High performance technologies are available that allow you to retrofit insulation into the wall cavity. Whether you choose bonded beads, ecofoam or another insulation type, you can stop the leaks and save money with retrofitted wall insulation.

As the image below shows – the wall insulation is simply pumped into the wall cavity through small holes drilled into the cladding or brickwork which are refilled and covered once the job is finished.

Different materials leak heat at different rates. This rate is called an ‘R value.’ Where possible, chose materials with the highest possible R value when retrofitting your home.
