We have had a number of requests recently to attend site and layer the head of the lift shaft with a fire board solution and sealing the perimeters with intumescent acrylic. We are definitely NOT bored with this as not only does it help raise compliance within the lift shaft, it also allows our team to deal with creating a smooth and well finished work of art!
layering the board like this allows improved fire protection and prevents the spread from the shaft area to the roof compartmentation.
