Blast Resistant Doors
Our blast door designs have been independently tested in accordance with the procedure under ISO/FDIS 16933 to verify their ability to withstand a blast loading. When a customer specification is received we have the calculations independently verified to ensure the highest levels of protection and performance. Below are some examples of the different applications for which we can design blast doors.
Explosion and Fire Containment
The most common function of a blast door and its surrounding walls is blast containment. In this application, the door will remain fully intact ensuring the blast is fully contained (Blast Proof). During testing, our doors performed to category I, meaning that the door remained closed post-blast and was still fully operable – important should the area require quick evacuation.
Fire-Rated Blast Doors
We have developed a composite blast door designed and tested for use in petrochemical applications. These steel door sets merge the principles of blast design with the requirements of 4 hour fire certification and are tested to BS EN 1634-1:2008. The doors are equipped with an external lever handle for key entry and internal panic bar assemblies for use as emergency exits. Insulation: The storage of munitions requires a dry, temperature-controlled environment. We design to meet these requirements by using door set insulation and purpose-specific seals to prevent sweating and cold transfer from the external face of the door to the internal face. This ensures a stable environment for contents of the building whilst maintaining the required level of blast containment. Blast Windows: Our blast windows have also been independently tested and achieved ISO 16933: 2007 Hazard Rating A. We use this design of window to provide maximum containment whilst also providing aesthetic value and clear visibility both internally and externally to the structure.
