Swarf particles, if left on the surface, will corrode and cause rust stains which will detract from the finished appearance of a project. These stains are often mistaken for early deterioration of the roofing and walling itself.
Please note: Surface protective films that cover sheets are highly sensitive to heat and direct sunlight. Excessive heat and direct sunlight before taking off the film can cause gluing of that film to the sheet surface, after which it will not be practically possible to remove it from the sheet.
In order to protect the sheets, they must be installed with the marked UV protective layer facing outside. Although sheet products can also be UV protected on both sides, most of the sheets are protected on one side that is marked clearly.
The r-value represents the insulation’s resistance to heat flow (m².K/W) at a given thickness. The higher the r-value of the insulation, the better its performance will be.
