Energy Efficient Windows - Window Upgrade - Misty Glaze

Can I achieve energy efficiency windows whilst retaining my existing window frames?

Yes, you can. At Misty Glaze we offer replacement of the glass panes only within your existing frames to achieve energy efficient windows. Aside from the massive advantage of reduced upheaval to your home life, replacing only the panes for energy-rated windows means that you’ll save money on the installing and on your future heating bills. So, it’s a win-win-win!

The British Fenestration Rating Council – the UK’s most trusted rating council for verifying the energy performance of windows and doors – rates the thermal efficiency of windows on a scale of A to G (A being the most energy efficient and G the lowest). In the UK, most homes lose an average of 20-30% of their heat through old, faulty or broken windows. Poor installation and poor insulation are often the biggest hindrance to A-rated windows.

Benefits of replacement energy efficient windows

Cost effective

Our window replacement glass service is more affordable way of achieving energy efficient windows as it replaces only the panes within your existing frames. An A-rated windows upgrade by Misty Glaze is the perfect efficiency solution for those with windows rated below C.

Noise Reduction

A-rated windows also reduce noise reduction, useful for those living within industrial areas or close to busy roads. Our enhanced acoustic glazing options can replace your existing window panes and suit the look of your home.

Reduced condensation

Misted window panes, condensation dripping inside of your faulty panes or onto your windowsill not only causes damp that can lead to health problems, but it’s unsightly and depressing. By replacing any affected panes with energy saving, A-rated windows you’ll immediately notice a huge difference. We only ever replace the panes not the frames, so all the benefits of energy efficient windows are easier and cheaper to achieve than ever.

Energy efficient

Replacing any older glazing with the latest energy efficient windows can be relatively inexpensive and bring a huge difference to the comfort of your home, as well as noticeable savings on your future heating bills. The low emissivity coating in energy-rated windows helps them to reflect heat back into a room – reducing the amount of heat lost and your carbon footprint.

Matching existing window designs

A common worry is that upgrading to the best A-rated windows means changing the look of your house. This is not the case. Our method of replacing the panes and never the frames means that we can simply fit energy efficient windows into existing frames, matching any glass or building style.

What is energy efficient double glazing?

An energy efficient DGU (Double Glazed Unit) consists of two or more panes of glass sealed together.

A++ Window Upgrade - A-Rated Windows - Misty Glaze

Components of heat insulated double glazed unit is comprised of seven components:

  1. The glass – This would consist of 4mm Low Iron on the external pane and Low-E (with the manufacturer, make or model of clients choice. Misty Glaze can also make recommendations) on the interior pane.
  2. Spacer bar – This is the frame that separates the 2 panels of glass. Creating an air tight cavity that helps to insulate the glass pane. You will find aluminium versions on the older style panels that are less insulated. A warm edge spacer bar is used on heat insulated double glazed units.
  3. Desiccant – This is a silicon material used within the spacer bar that will dry the moisture trapped within the cavity. Much like the little packets that you see in trainer boxes and clothing etc.
  4. The primary seal – The barrier to protect moisture and air from attacking the double glazed unit.
  5. Gas within the cavity – This usually consists of Argon gas, but can be other types of gas as requested, such as Krypton and Xenon.
  6. The cavity – This is the void formed between the 2 panes.
  7. The secondary seal – This is the main hot-melt structure adhesive sealant around the edge of the unit that seals the 2 pieces of glass together.

Please note: Please note: Energy efficient windows must be C-rated to meet the Energy Saving Recommendation certification. An A++ window rating is for windows with the highest efficiency levels.
