Are you thinking of changing your double glazed windows, but not sure it’s worth the cost and the disruption? With UK energy prices higher than ever, it is more important than ever to ensure your house is as energy efficient as possible. With new technologies improving double glazing’s effectiveness through the years, we’ve gone through all the advantages, disadvantages, costs and savings made by upgrading your double glazing.

What Are The Benefits of Double Glazed Windows?

Is It Worth Changing My Double Glazing?

In short, yes, it is worth replacing your old double glazing. Outdated double glazing could be costing you money and could make a home colder in the winter months. In layman’s terms, older “K Glass” double glazing is around 30% energy efficient – meaning that 70% of the heat from your home will be lost through the windows! In comparison, our signature Maxitherm™ insulated double glazing is up to 90% energy efficient installed into uPVC frames.

Will Double Glazing Make My Home Warmer?

In Simple Terms…

Thermal transfer, solar gain, dew point, sound frequency and conduction – what all this information means in reality is that double glazing will:

  • Keep more external noise out of your home
  • Retain more heat and keep your home warmer
  • Reduce condensation on your windows
  • Reduce the amount of energy you use to heat your home
  • Reduce your energy bills
  • Add value to your home

Maxitherm™ Insulated Double Glazing – The MOST Energy Efficient Glass Available

Our signature Maxitherm™ insulated glazing is far more advanced than a standard insulated glass unit, as it works in a completely different way from standard double glazing. The inner pane of the window is made from a special low emissivity glass – the Maxitherm™ secret ingredient that you won’t find anywhere else! Low emissivity glass is a type of insulating glass, which increases the energy efficiency of windows by reducing the transfer of heat or cold through the glass. That means in the winter your house stays warmer, and in the summer it stays cooler.

Warm-Edge Spacer Bar

Our spacer bars are made from fibreglass rather than metal, as fibreglass is a very poor conductor of heat or cold. This will keep your home warmer, as none of the cold from outside can be transferred through the spacer bar.

Argon-Filled Cavity

The space between the 2 panes of glass (or cavity), is filled with dense argon gas. Argon is an inert gas, which is also a very poor conductor of heat or cold, and has no moisture to cause condensation.

Soft Low-E Coating

Maxitherm™ double glazing includes a pane of soft-coated low-emissivity glass designed to prevent heat escaping through the windows to the cold outdoors in Winter – this also keeps it cooler in the summer by reflecting the heat out.
