Energy saving products

Washing machines, refrigerators, dishwashers and boilers are just a few products purchased every day with an energy efficient rating. Rated from A to G, with different coloured bandings, the Energy Ratings label gives the consumer an idea of how efficient the product is in respect of how much fuel the product requires to operate. The higher the energy rating (A being top) then the less fuel.

Products which meet strict criteria on energy efficiency can
also carry the blue Energy Saving Recommended logo. Energy Saving Products

  • Crystal Vision provides an 'A' Rating as standard.

Energy rated windows

As with refrigerators and dishwashers it is now possible to buy energy rated windows for your home or property. The British Fenestration Rating Council (BFRC) energy performance label will perform the key functions of:

  • containing and conserving heat in winter
  • keeping the building cool in summer
  • reducing draft and resisting condensation

This is achieved by enhanced levels of window performance in the critical areas of Thermal Transmittance (U-value), Solar Factor (g-value) and Air Leakage (L50 Value)

  • Crystal Vision gives a minimum  “A” rating as standard.

Platinum NRG Triple Glazing

PlatinumNRG Triple Glazing uses three panes of glass which form two insulating layers that provide the ultimate thermal and acoustic insulation. The industry-leading 6 chamber PVCu profiles elimate the need for thermal inserts and use structural PVCu for rigidity rather than heat-conducting steel.

PlatinumNRG Triple Glazing can exceed even the A-Rated window by over 35%.

The additional cavity created by having 3 panes of glass can increase sound insulation by over 20%, as well as offering extra security. You should always seek professional advice for Triple glazing as it may not always suit your property or needs. 


FENSA stands for Fenestration Self-Assessment Scheme. Following Government encouragement, FENSA has been set-up by Glass and Glazing Federation. (GGF) and other industry bodies, in response to Building Regulations

for double glazing companies in England and Wales. When replacing windows and doors, homeowners must comply with current thermal performance standards and ensure they obtain a certificate from FENSA (or similar approved) or Local Building Control.
