The energy efficiency of windows are measured by Window Energy Ratings. WER's take into account the performance of both frame and glass known as a whole window ratings, and are determined by three main factors:

1. Thermal Loss (U-window) - measures heat that is lost through the overall window - energy efficient windows reduce heat loss, therefore a lower u-window valure means better nergy efficiency.
2. Heat gain (G-window) - measures the amount of heat that is absorbed from the sun - energy efficient windows transmit solar heat back into the room, helping the lower home-heating usage.
3. Air Leakage/Loss (L-factor) - measures heat loss that occurs as a result of general air leakage - an energy efficient frame and glass will help reduce air leakage.

Energy Rated Windows - the benefits for home owners:

1. Save money on home heating - your heating bills could be reduced by up to 20% per year.
2. The environment - energy efficient windows will help ensure you do "your bit" for the environment and could reduce your CO₂ emissions by up to two tonnes.
3. Current building regulations - energy efficient windows adhere to currently building regulations for new build properties and houses for sale or rent. If you are selling your home, energy rated windows could help add to the overall value of the property.

Glazing types

We offer a wide choice of double and triple glazed windows to give you the lowest possible U-Value.

Double glazing

With "A" rated units like Camden eCare Select+ windows (U-Value: 1.4) and "B" Rated Camden eCare Advantage+ windows (U-Value: 1.45) everyone can find a product matching their needs and budget.

Triple glazing

Triple glazed windows offer even higher savings. With either Argon or Krypton filled cavity you can achieve U-Value of 1.2 and lower - which results in less heat lost.

Spacer Bar

In the past windows fitted in our homes and offices feature metal bars separating the panels of glass in the sealed unit. However metal bars are highly conductive, and this results in heat loss and condensation, leading to problems for you and the environment.

Super Spacer is 950 times less conductive than standard aluminium spacer bars.

Super Spacer is a foam-based spacer bar and therefore is less conductive than a standard metal spacer bars. This provides many advantages:

• Heat loss is reduced by up to 94% which in turn reduces heating bills
• Reduces noise transmission by up to 2dB
• Condensation is reduced by up to 70%, which also eliminates bacteria on your windows
• 65% warmer internal edge, which means thermal bridging is all but eliminated
• Less energy emissions are released into the environment
