Future-proof your property.

Triple-glaze your home or commercial building in St Mary Cray or anywhere in Greater London.

Triple-glazed windows and doors are increasingly popular among energy-conscious property owners and developers across Greater London and the UK. Whether upgrading your existing property or designing a new one in St Mary Cray BR5, triple-glazing offers incredible benefits, including superior thermal insulation, excellent soundproofing and security.

Future-proof your home or commercial building and enhance its resale value with our A++ rated triple-glazed windows and doors - the premier solution for consistent warmth and a peaceful, energy-efficient environment all year round.

First, we'll assess your current window or door frames to ensure they are structurally sound and can support the additional weight. Triple-glazing is significantly heavier than double-glazing; in cases where existing frames do not meet requirements, we may need to reinforce or replace the frame entirely.

Alternatively, you can opt for our heavy-duty Mega Hinge, which is fitted as standard to all side-hung openings and can comfortably accommodate an opening sash weighing up to 40kg.

Race to Zero

Future Homes Standard (FHS)

The Future Homes Standard (FHS) is a set of building regulations set to take effect in the UK in 2025.

Triple-glazing is one of several energy-saving methods that can be used to achieve this.

As the Race to Zero accelerates, we can expect significant changes in standards that will affect property owners across Greater London and the UK. Our triple-glazing services in St Mary Cray BR5 and throughout Greater London comply with all the latest Building Regulations.

5 good reasons to triple-glaze your windows and doors in St Mary Cray BR5 and Greater London:

Superior energy-efficient triple-glazing in St Mary Cray

A++20 BFRC energy rating – as standard!
The British Fenestration Rating Council (BFRC) evaluates and certifies the energy-efficiency of windows and doors across the UK, with ratings ranging from E (least efficient) to A++ (most efficient).

In layman’s terms, the Eco Energy Plus triple-glazed window is significantly more energy-efficient than any standard A-rated double-glazed window on the market.

Superior insulation with triple-glazing in Greater London

1.0 U-Value - as standard!
The Eco Energy Plus triple-glazed window offers a low U-value of 1.0 as standard, with even lower U-values available to suit your specific needs. The lower the U-value of your triple-glazed windows and doors in St Mary Cray BR5, the better their insulation performance.

The Eco Energy Plus triple-glazed window is a highly energy-efficient choice for environmentally conscious home and business owners across Greater London and the UK. The additional layer of glass that makes your window or door triple-glazed results in two air gaps forming between the glass, trapping significantly more heat than double-glazing.

Triple-glazing makes your property airtight, so to ensure adequate ventilation, consider options such as trickle vents or a mechanical ventilation system to prevent condensation or mould. We install triple-glazed windows and doors in St Mary Cray BR5 and throughout Greater London.
