Specifying Fire-Rated Rooflights from Natralight
The degree of protection offered depends on the type of fire-rated glass used, but generally all fire-rated glass acts as a barrier to help prevent the spread of flames and smoke in the event of a fire.
Certain types of fire-rated glazing will also provide a degree of insulation against the heat of a fire. The ability of glass to prevent the spread of fire throughout a building is one of the most important features.
The use of fire-rated glass is a crucial component in building safety plus Building Regulations, where specified.
Building Regulations Explained
Fire safety features in Approved Document B of the Building Regulations for both England Wales. This states where and at which levels of fire resistance products should be used in domestic and commercial buildings.
For buildings other than dwelling-houses, ratings of up to 180 minutes could be required depending on if sprinklers are installed, the height of the building and the depth of the basement. It is worth noting that the operation of sprinklers can affect the performance of fire-resistant glazing.
Approved Document K of the Building Regulations covers protection against falling, collision and impact, identifying certain parts of internal and external walls as critical glazing locations, where the glass must be impact glass.
Doors and side panels must be class 2 if the width is greater than 900mm, and class 3 if the width is more than 250mm and less than 900mm. If panes are of a thickness greater than 6mm, with a width less than 250mm and area less than 0.5m2. Impact-rated glass is not required.
