Product certification provides assurance to specifiers, contractors and purchasers that products will perform to an agreed standard. BM TRADA has offered a range of certification schemes under our Q-Mark brand for building products for over 20 years. We can also provide CE marking certification.
Window Energy Ratings Certification
BM TRADA is approved as an Independent Agency for the BFRC (British Fenestration Ratings Council). Our Window Energy Ratings certification scheme allows manufacturers to apply to use the energy rating label on their products (pictured right).
Conventional approaches (such as setting a glass or window U-value) simply assess how much energy a window loses. They do not take into account how much energy a window can gain.
The total energy flow in a window consists of three major components:
- Thermal transmittance (U-value)
- Solar factor (g-value)
- Air Leakage (L50)
The British Fenestration Ratings Council (BFRC) has devised a Window Ratings equation based on values for these components. The rating is expressed as a number. The rating is converted into a grade between A and G (with A being the most energy efficient).
Certificate Number : 002 – date of certification : 30 April 2012. BM Trada scheme for verification of performance characteristics for CE Marking of windows and doorsets in accordance with BS EN 1435101
Under the Construction Products Regulation (CPR) CE marking has become mandatory for many construction products in the UK from 1st July 2013.
CE marking is the only way to demonstrate that a product, or system, complies with the CPR. It is a manufacturer’s declaration that their product meets the minimum requirements of a harmonised technical specification, enabling them and their agents to place their product on the construction market.
