Application Guide

So that pro clima IN­TELLO works ef­fi­ciently and can pro­tect the thermal in­su­la­tion from struc­tur­al dam­age and mould, it needs to be in­stalled cor­rectly. Here we show you what you need to spe­cific­ally con­sider dur­ing the in­stall­a­tion, step by step.



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 overlap bonding.

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.


Additional instructions for blown-in insulation materials

INTELLO PLUS can also be used as a boundary layer for blown-in insulation materials of all types. A reinforcement structure ensures that there is little expansion during the blowing-in process. Installation in parallel with the supporting structure has the advantage that the joint will be on a solid base and is protected by this base.

The separation distance between the staples used to fasten the membrane strips must be a maximum of 5 to 10 cm (2 to 4″). If installation is carried out perpendicular to the supporting structure, a supporting batten should be fitted directly over the membrane strip overlap with its airtight bonding in order to avoid tensile loading on the adhesive bond.
Alternatively, the adhesive tape on the overlap can be strengthened with additional, perpendicular strips of adhesive tape every 30 cm (12″).
When working in cold outdoor climates, the blown-in insulation material should be inserted immediately after installation of INTELLO PLUS. This will protect the membrane against condensation formation.
