The FS FireCheck comprises an intumescent impregnated glass tissue which is manufactured within the Ampelite sheeting. The chemicals are halogen-free meaning they are nontoxic. The simplicity of the approach to using the tissue and locating it at the surface of the sheet results in no loss of strength or stiffness within the composite section.
The patented ClearSlide fixing clips provide many advantages over normal installation procedures and also allow the combination of metal roll form decking and

Calculations For Commercial
Roof Vents – Size & Number
1. Determine the volume of the building
Volume of section A = 0.5 x L x W x Ha
Volume of section B = L x W x Hb
Calculating Total Building Volume
Add the Volume of section A + Volume of section B
Note: For factories, the combined volume A + B should be used.
Where Volume B is air-conditioned, only Volume A is used
to calculate the number of ventilators required. No air
should be drawn from the air-conditioned space below
2. Select the number of ventilators required METRIC = V x Ac/Hr EX/
Where: V = Volume of building or roof space. Ac/Hr = Air changes per hour. EX/c = Exhaust capacity of ventilator
Using ventilators in the ceiling space of air-conditioned buildings reduces the load on the air-conditioning plant and helps reduce power consumption accordingly. Well worth the initial investment for vents and installation cost.
