WINTEQ INSULATION

Introduction

Cases of structural damage caused by condensation water collecting in and around joints between the building shell and windows, window elements or doors have risen strongly in the past few years. Extensive Winteq insulation system is designed to prevent such a damages.

How to seal in a EN-conforming way?

1 - Inside protection

The inner joint area must be airtight towards the living space in order to separate the room climate from the outdoor climate. At this level, the temperature must be above the critical room temperature for mould formation (80 % air humidity / 13 °C isotherm).

2 -Thermal separation

In the centre area of the joint, thermal and acoustic insulation must be ensured over an appropriate period of time. This area has to stay dry.

3 - Outside protection

On the outside, the joint must be protected from rainwater and driving rain. Water that penetrated must be controlled and directly drained off to the outside. At the same time, moisture must be allowed to escape from the functional area to the outside.

Why are the functions of the three levels so important?

There are many sources of moisture and dampness in the home and non-domestic buildings. A three-head household releases approximately 6-12 litres of water into the ambient air per day. In unfavourable conditions (inappropriate air circulation, low surface area temperatures) this can lead to condensation and even mould infestation.

Solution

WINTeQ meets these requirements with an optimized constructional product system. While the joint is sealed against the penetration of wind and rain from outside, water vapour permeable materials such as WINTeQ foil exterior or WINTeQ compressed tapes, allow water vapour to pass from inside to outside the building. High thermal and sound insulation is ensured by Makroflex PU-foam. The system is supplemented by a vapour-proof sealing layer that significantly reduces the penetration of moisture from the interior rooms into the joints.
