Insulation - Tips and Facts

Insulating floors and ceilings makes a home cosy and welcoming.

By saving energy in the home, you are not only helping yourself, you are also helping the planet.

If a house already has a thin and ineffective insulation, it is worthwhile adding an extra layer on top.

The money you spend now in insulation will soon pay for itself in reduced energy bills and additional comfort in the future.

Insulation performance is measured by R-value, the higher the R-value the more effective it is.

Even if the air temperature is cold, a person standing on a warm floor will feel more comfortable. Damp houses are unhealthy to live in, insulating under your floor will make your home dryer.

If you have cold and draughty floors, you will waste power heating your home.
