Insulation, How does it work?

Here at Next Home we work hard to provide the best advice to our clients to achieve the best results for them whether that be achieving the highest sale price or our mortgage team working to decrease your mortgage and insurance bills so, we thought we’d provide you with some information about insulation to reduce your energy bills!

It is really important to make sure that your home is as insulated as possible to try and keep those utility bills down as there is no point in trying to heat your home and stay warm if all the heat is escaping through the walls, windows and roof!

An uninsulated home loses heat several different ways:

  • 25% is lost through the roof
  • 33% through walls
  • 15% through floors
  • 15% through draughts
  • 20% through windows

New build properties are often insulated to the highest standard so, if you live in or are purchasing a new or nearly new build property then it is likely to be insulated to the highest standard.

Sometimes older properties are a little lack lustre but, there are changes that can be made to improve the insulation and energy efficiency of your home!

Roof Insulation

There are several different types of roof insulation including glass wool, batts of mineral and spray foam insulation. You can also add similar types of insulation to ceiling cavities between floors.

Wall Insulation

Most commonly this is where there is a layer of foam between the outer and inner walls, basically filling the cavity of air. There are also wool and spray foam alternatives. Depending on the age of your property there may not be a wall cavity to fill or it may depend on how the original building was divided.


Having fully sealed and well maintained windows is key to maintaining heat in your property which is why more often than not properties have double glazed windows. The air that is trapped between the two layers of glass doesn’t allow air to circulate and therefore cannot conduct and create a convection to allow heat to escape from your home. You must make sure that the seals are well maintained in your windows other wise the air can circulate, you’ll be able to see this if condensation starts to form between the panes as moisture is able to gain access. Sometimes you will find newer properties may even have triple glazed windows.
