Premium Glass Upgrades

Up to 26% of all heat lost in the home escapes through the windows.


Modern energy efficient glass allows more warmth from outside to pass through whilst simultaneously retaining heat from within the room. Installing these windows within your home could save you up to 22% on your heating bills.


EnergiGlass will fully refurbish and upgrade your existing windows without replacing the frames, unless absolutely necessary.

Why Choose Our Glass

Our sealed glass units are made up from the UK’s best selling low emissive glass, Planitherm Low E glass which stops heat escaping, and Planitherm Low Iron Glass, which allows more solar heat into your home.


The sealed units are bonded together with a Warm Edge Spacer Bar that, unlike traditional aluminium spacer bars, prevents heat escaping.


With ever increasing energy bills, it’s becoming more important to ensure your home is as energy efficient as possible.

Replacement Doors and Windows

EnergiGlass offer replacement windows, UPVC doors, composite doors, patio and French doors and Door locks all in a range of colours, styles and designs.

Fascia, Soffits and Gutters

EnergiGlass is one of the fastest growing Roofline companies in the UK, making us the obvious choice for replacement Roofline products.


The lack of ventilation in wooden systems causes condensation in the roof, which in turn rots felt, joist ends, soffit and fascia boards.


Not only is this rot bad for your home, but can also lead to bigger problems such as asbestos, insect infestation and birds nests.


We will replace any damaged and leaking roofing felt under the outer edges of the roofing structure, integrating the existing roof with our triple eaves system, which allows ventilation and prevents condensation.
