Why our British Board of Agrément certified windows are top class

12th December 2016 |

Company News

When it’s time to replace your existing windows, you want to know that your new windows are the best they can be. At Majestic Designs, we manufacture a range of uPVC windows which are certified by the British Board of Agrément (BBA). The BBA provide reassurance to manufacturers, insurers and consumers. Specialising in construction and property, the BBA carry out rigorous tests to ensure only the best quality products gain their approval.

Not many window and door manufacturers have BBA accreditation. At Majestic Designs, we strive for excellence in everything we do. By testing our products to BBA standards, we ensure that high quality is consistently maintained. Every window and door we manufacture has been through rigorous tests to ensure that our customers only receive the best quality products.


Top class testing

The BBA conduct a variety of tests in the following areas:

  • Durability
  • Energy Efficiency
  • Mechanical Function
  • Weathertightness
  • Wind Resistance

Excellent Endurance

When testing the durability of windows and doors, the BBA carry out tests that are designed to replicate the natural life of the product. The windows are exposed to fluctuations in temperature to assess their heat and cold resistance. Exposure to extremes of -30°C and between 40°C and 1500°C ensures the windows are more than capable of withstanding the British climate.

The windows are also exposed to UV radiation. A fluorescent tube and xenon arc are used to mimic the sun’s rays. During the process the windows are monitored for discolouration and deterioration. Thermal cycling helps to gauge the reaction of the windows over a specified time period.

The windows are sprayed with a natural salt spray. This tests their resistance to corrosion from the elements. The windows are placed in a salt spray chamber where they are exposed to acids, alkalis and other chemical agents.

Thermal performance assessment

The window’s U-value is calculated using a guarded hot box. A guarded hot box is designed for testing windows, doors and wall panels. Thermal conductivity and resistance is tested using heat flow meters which provide an accurate and realistic energy rating.

The reflectivity and insulating properties of the window are also tested. In this modern world, it is increasingly important to reduce our carbon footprint. Producing windows that are energy efficient helps our environment, thus protecting our children’s futures.


Mechanical testing

Every part of the window system is tested for strength and functionality. Weights are hung off the window frames to test the shear strength and tensile properties of the window. Bond strength, compressive strength and flexural properties are tested using state of the art machines and equipment.

Tests are also carried out to assess security, operation and impact resistance.

Protection from the elements

The BBA perform tests for water tightness, wind resistance, air permeability and UV resistance. Severe weather conditions are simulated in a special laboratory to expose the window to the most extreme conditions possible. These tests are designed to ensure our modern windows are top class and provide a secure barrier to any external factors.

When you choose Majestic Designs to supply and install your windows, you get the best in quality and craftsmanship every time. Our BBA certification helps to give peace of mind to our customers. The BBA only certify quality products, so you can be sure that with Majestic Designs you will enjoy an improved standard of living with every installation. With BBA certified windows your home will be secure and energy efficient for years to come.
