Application of work: Installed all fire rated 75mm polystyrene with a rating of 1.5R on batons. Expansion joints had to be every 3.6 metres or above and below windows and doors. Expansion joints were created by our installer, expansion joints were then corked, this is a must.
Stainless steel angles applied to all windows and doors. A 75mm aluminum channel was installed to the bottom of the styrene to prevent any moisture from rising.
Render application: 1st coat to skim all polystyrene with wetpatch and bed in fiberglass mesh.
2nd coat was the application of Acylic render and the render had to be specified by the manufacturer of the styrene, otherwise manufacturer’s warranty becomes null and void if the correct system is not applied.
