Installation and fastening
Where possible, INTELLO and INTELLO PLUS are
installed in such a way that adhesion can be
carried out using single-sided adhesive tape on the smooth (printed) side of the sheeting. They can be installed taut and without slack either in parallel with or perpendicular to the supporting structure, e.g. the rafters. In the case of horizontal installation
(perpendicular to the supporting structure), the separation distance of the supporting structure is limited to a maximum of 100 cm (40″). After installation, perpendicular battens on the inside at a separation distance of a maximum of 50 cm (20″) must be fitted to carry the weight of the insulation material. If regular tensile loads on adhesive tape bonds are to be expected – for example, due to the weight of the insulation material – when using mat or panel-shaped insulation materials, an additional
supporting batten should be fitted over the
When attaching the membranes in the case of mat or panel-shaped insulation materials, a maximum separation distance of 10 to 15 cm (4 to 6″) applies for the fastening staples, which must be at least 10 mm (0.4″) wide and 8 mm (0.31″) long. The overlaps between the membrane strips must be approx. 8 to 10 cm (3 to 4″).
Airtight seals can only be achieved on vapour control membranes that have been laid without folds or creases. Ventilate regularly to prevent excessive humidity (e.g. during the construction phase). Occasional rush/inrush ventilation is not adequate to quickly evacuate large amounts of construction-related humidity from the building. Use a dryer if necessary.
To prevent condensation, INTELLO should be stuck down so that it is airtight immediately after installing the thermal insulation. This particularly applies when working in winter.
