Retrofit Low-E-Plus heat-retaining glass into your existing window frames for a cosier home
Keep your existing window frames and retrofit Low-E-Plus™ heat-retaining glass. Enjoy the warmth and comfort of triple-glazing and lower heating bills.
Retrofit Low-E-Plus heat-retaining glass into your existing window frames and save heat and money
Low-E-Plus™ heat retaining glass is an energy-efficient double-glazed unit that is designed to prevent even more heat escaping through your windows to the cold outdoors. It is perfect for retrofitting into existing window frames.
By upgrading your existing double glazing to advanced Low-E-Plus2™ heat-retaining glass and improve the efficiency by as much as 68%! – without changing your uPVC window frames AND without the need to redecorate! And, as you are only changing the glass you can save up to 50% of the full cost, with most jobs done and dusted in a day.
What are the steps involved in a glazing upgrade?
Step 1
Heat escapes through old window glass leaving your home very cold
Step 2
Keep your existing window frames and remove the old glass
Step 3
Retrofit Low-E-Plus™ heat-retaining glass into the frames
Step 4
Low-E-Plus™ reflects heat back inside and reflects cold back out
Retrofit Low-E-Plus™ double glazing into your existing window frames and stop heat escaping
Energlaze Low-E-Plus™ glazing units have a low U-value of just 1.0 W/m2K. They can significantly reduce the heat-loss from your existing windows and be as effective as triple glazing when retrofitted into an existing double-glazed window frame.
Low-E-Plus™ can be retrofitted into any type of window frame: uPVC, timber or aluminium. It comes as standard in all our new uPVC windows.
Low-E-Plus2™ has TWO heat-retaining low-e coatings and is designed for retrofitting into uPVC frames only
Low-E-Plus 2™ has two heat-retaining coatings, just like triple glazing. They reflect interior heat back into the home and also keep the cold out. It has a U-value of 0.9 W/m2K , this means you enjoy a warmer, more comfortable home and your heating bills are reduced. Low-E-Plus2™ is designed for retrofitting into uPVC frames only.
A lower U-value = a more effective insulating material

Will changing my glass get rid of my condensation?
This is usually a ventilation problem and cannot be caused purely by the installation of heat-retaining double or triple glazing. By acting as a heat barrier and providing an inner pane which is considerably warmer than the outer pane, condensation may be reduced. For more information visit our condensation information page.
Can I upgrade just one window?
No. We recommend a minimum of half-of-house upgrade (usually 3 or 4 full windows) to get the full impact of the heat-retaining glass. For more information on this please feel free to contact us.
What does it cost to replace my glass with new heat-retaining glass from Energlaze?
Pricing can vary based on the project – that is why we offer a free no obligation survey and quote. Get expert advice from a glazing specialist and make your home as warm and comfortable as possible. Get a free quote here
Are the heat retaining coatings invisible and permanent?
Yes and yes. The coating is transparent and microscopic so you won’t notice them. And they are hermetically sealed during manufacture, making them durable and permanent. Get a free quote here
I have alarms on my windows - do I need do do anything beforehand?
Yes. If your alarm has sensors on the window or glass, these will need to be removed. In some instances, you will need to have your home security provider remove these for you. Energlaze fitters cannot remove them on the day of fitting. Failure to remove sensors will delay your fitting.
What happens to the old glass?
All debris is removed from site and recycled where possible. The fitting team will lay down dust sheets where they are working & clean up once they are finished.
