Roof insulation external

When use of SWP by the construction element is considered, most of it is applied externally (as external walls and facades, 56%), followed by roof insulation (30%) and for ceilings, internal and partition walls (14%). SWP can also be installed as wall panels with integrated windows, for various indoors separations, as acoustic roof panels and as construction accessories (variable connecting SWP panels to connect individual wall and roof panels) and in prefabricated housing and shelters. 

These foams are used for board stock in commercial and industrial buildings as insulation for internal cavity and external walls, roof, floor, and foundations. Spray-appHed foam, covered subsequently with one of a variety of protective coatings, is widely used for large roofing appHcations and has limited use as external walls. Eor residential buildings, the principal use is as external sheathing board. 

Provide a similar blanket of insulation on top of any suspended ceiling which is 300 mm below the flat roof or an external hot liquid spray-on type of insulation to the roof finish.
