New uPVC casement windows: Swap old and cold for stylish, warm and secure.
New Energlaze uPVC casement windows offer advanced warmth and comfort. Choose from a range of styles and colours to suit your home.
New uPVC casement windows from Energlaze will help stop valuable heat escaping
Energlaze uPVC casement windows offer high thermal performance. With its 5-chamber system our double-glazed windows can offer U-values as low as 1.3 W/m2K (based on a 28mm unit). This means you will notice your home is warmer for longer and your energy bills will be considerably lower. Energlaze windows are up to 68% better than old windows at preventing valuable heat from escaping. This means you don’t need the heating on for as long, saving you a bundle. And less energy required to heat your home means a greener, healthier home and a reduced carbon footprint.
Triple glazing option also available
We also offer the option of installing triple glazing into new uPVC casement window frames. Triple glazing costs more and does provide an improved level of overall thermal insulation. However, this may not be as easily noticed when compared to our more cost-efficient heat-retaining double-glazing. Read more about insulation and U-values here.
Note: Lowest triple-glazing U-value of 0.8 W/m2K based on a 44mm unit.

Important information everybody should know about their glass and windows

Stop condensation

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.
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.
