Quality & Accreditations

PlatinumNRG is one of the best performing products on the market, taking full advantage of the increased thermal efficiency offered by its four or six chamber sash and outer frame, providing the most energy efficient windows available.

Made from 100% lead-free PVCu, PlatinumNRG incorporates advanced engineering and quality manufacturing with the highest security available



Product Certifications:

  • Enhanced Security Doors Certification PAS 24: 2022
  • General Performance Windows – BS7412
  • Enhanced Security Windows Certification – BS7412

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

Energy Window RatingBM 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 (pictured right) on their products.

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 and is converted into a grade between A and G (with A being the most energy efficient).

UKCA Certification


The new UKCA (UK Conformity Assessed) Marking scheme has been operation since January 2021. However, to allow businesses time to transition, the implementation was delayed. UKCA is designed to mimic CE (mirroring BS EN 14351) over all industries and sectors, meaning there will be little change and that it will generally operate in the same manner as CE Marking. Under the UKCA Marking scheme, only U-Values are acceptable in showing compliance – window (WER) and door energy ratings (DER) are not suitable.

From the 1st January 2023 the UKCA mark must be shown. We have been for some time fully UKCA compliant and all relevent Markings appear on the appropriate paperwork.
