Eco Defender System Energy Rated Windows 
Advanced window  offering unbeatable thermal efficiency, superior aesthetics and great value.

Designed to meet rising demand for more energy-efficient products, our Eco Defender energy rated window features a unique six-chamber outer frame which has achieved an ‘A’ rating from the British Fenestration Ratings Council (BFRC) – the highest rating possible. Eco Defender is also slimmer than standard profiles, enhancing the appearance of any window and increasing the area of glass for improved sight lines.

Why choose Eco Defender energy rated window?

Eco Defender enables you to achieve outstanding energy efficiency – helping customers save on their energy bills whilst protecting the environment.

Eco Defender give you a slim, unobtrusive window frame that increases the area of glass for brighter interiors and enhanced sight lines.
Available in sculpted ovolo or contemporary chamfered styles and a range of colours and wood grain finishes. There’s a Eco Defender style to suit any home. A selection of decorative options is also available, including ovolo beads, mock horn sashes, arched tops and Georgian bars.

Regulatory measures are being brought to bear to help improve energy efficiency in buildings. The Building Regulations relating to new windows in home extensions are becoming increasingly strict, while the Code for Sustainable Homes sets out mandatory energy-efficiency standards for all new-build properties. For commercial and public-sector buildings, BREEAM environmental assessments set out similarly stringent guidelines.

energy efficient windows

Homeowners are increasingly demanding energy-efficient products to help cut energy consumption and reduce their energy bills. Furthermore, Home Information Packs (HIPs) now rate properties for energy efficiency on a scale from A to G, similar to that used on white goods. Windows themselves are rated for energy efficiency by the BFRC (British Fenestration Rating Council) on the same scale, making it easier for consumers to choose the best-performing products.

What Does the Energy Efficient Window Ratings Label Tell You?

The BFRC Scheme is the UK’s national system for rating the energy efficiency of windows and is recognised within the Building Regulations as a method to show compliance for your replacement windows installation.

Window Energy Ratings use a consumer-friendly traffic-light style A-E ratings guide similar to that used on ‘white’ goods (such as fridges, freezers, washing machines etc…). This ratings label can be used by you to make more informed choices about the energy efficiency of the windows you are looking to purchase.

With carbon emissions high on the global agenda and the current high cost of fuel, we are all looking for ways to make our homes more energy efficient.

Each window rated by the BFRC has a unique label

This label will display the following information:

1. The rating level – A, B, C, etc…
2. The energy rating eg. -3kWh/(m²·K) in this example the product will lose 3 kilowatt hours per square metre per year.
3. The window U value eg. 1.4W/(m²·K)
4. The effective heat loss due to air penetration as L
eg. 0.01 W/(m²·K)
5. The solar heat gain eg. g=0.43

Simply put this will determine how well a product will perform the functions of:

* Helping you contain and conserve heat within your building in the winter

* Keep out the wind

* Resist condensation

* Contribute to improved sound insulation

So What are Energy Efficient Windows – Use Solar Gain to Benefit the Home

So exactly what are Energy Efficient Windows? They are windows that help to contain and conserve heat within the home keeping out wind and rain, resisting condensation and yet allowing natural “free” energy - the warmth of the sun - to heat the home. They can be made using any frame material - aluminium, PVC-U, steel or timber or even a combination of materials.

Energy Efficient Windows are easy to recognise - simply look for the BFRC Label.
