Rigorous Testing and Compliance

At Fire Proof Window Company, safety and reliability are paramount. Our fire rated windows are subjected to rigorous testing to ensure they meet the highest standards of fire resistance and performance.

To achieve compliance with British Standards, our windows undergo a series of stringent tests. For example, they are tested to BS 476 Part 20, which assesses their fire resistance and integrity when exposed to high temperatures. Additionally, our windows are tested to BS 1634-1, which evaluates their ability to resist the spread of fire and smoke, and BS 476 Part 22, which measures their insulation properties during a fire.

These tests are conducted by independent, accredited laboratories to ensure impartiality and accuracy. The results provide assurance that our windows can withstand the extreme conditions of a fire and help to protect building occupants and property.

But our commitment to safety and compliance doesn't stop at testing. We also ensure that our manufacturing processes adhere to strict quality control measures, and our installation teams are trained to install our windows in accordance with industry best practices. This attention to detail helps to ensure that our fireproof windows perform as intended in the event of a fire.

By choosing Fire Proof Window Company, you can have peace of mind knowing that our fireproof windows have been thoroughly tested and meet stringent safety standards. Our commitment to safety and compliance is unwavering, and we strive to provide our customers with reliable, high-quality fireproof windows that they can trust.

60 Minutes of Resistance

Fire can spread rapidly, and every minute counts when it comes to protecting lives and property. That's why our fireproof windows are designed to provide 60 minutes of fire resistance, helping to slow the spread of flames and smoke.

During a fire, windows can be vulnerable points of entry for flames and smoke. Our fireproof windows are constructed with specially designed materials and components that help to resist the intense heat and pressure of a fire. The glass used in our windows is designed to withstand high temperatures without cracking or shattering, and the frames are made from materials that are resistant to combustion and deformation.

Our windows have successfully passed a 60-minute fire test conducted by Warrington Fire, an independent and accredited testing laboratory. This test involves exposing the windows to extreme temperatures and pressures to simulate the conditions of a real fire. The windows are evaluated for their ability to maintain their integrity and insulation properties during the test, and our windows have proven their ability to withstand these challenging conditions.

By providing 60 minutes of fire resistance, our windows can help to buy precious time for occupants to evacuate and for emergency services to arrive. This added layer of protection can make a significant difference in the outcome of a fire, and we are proud to offer fireproof windows that can help to safeguard lives and property.
