Is there a grant for new windows?
Yes. For more information, click here
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.
