SOLITEX® UM connect
Roof Weather Resistive Barrier with 3D Separation Layer and Self-Adhesive Strip
Advantages
- High performance monolithic nonporous membrane
- 30 separation layer provides ventilation between underlay
- connect technology available with two integrated self-adhesive strips
- High water resistance
- Low vapour resistance
- UV resistance up to 30 days
Areas of application
SOLITEX® UM connect is a four-layered roofing underlay with a 30 separation layer and integrated self-adhesive strips for sheet joins. It is suitable for roofing such as titanium, zinc, stainless, galvanised steel and copper. It is also suitable as a weather resistive barrier for internal retrofit with existing direct-fix cladding to ensure a gap is maintained between new insulation and the internal side of existing wall cladding.
Planning and construction guidelines
Areas of application
pro clima SOLITEX UM connect can be installed as a roofing underlay membrane on even roof sheathing made of solid wood or wood-based panels, underneath metal coverings. It stops cold external air from flowing through the building structure and ensures that the thermal insulation works in an optimal manner.
- Suitable for ventilated and non-ventilated structures in combination with all roof and facade materials such as titanium zinc, aluminium, stainless steel, galvanised steel, copper etc.
- Fibrous membranes protect the structure against permanent moisture and sheet metal corrosion. For this reason, they are recommended by leading providers of metal roofs.
- The 8 mm thick 3D fibrous layer made of fibrous PP protects the covering against waterlogging and dampens noise caused by rain or hail.
Dark marks may form on the membrane as a result of rainwater. These have no influence on the high level of watertightness and the effectiveness of the interior membrane.
Increased indoor humidity
These highly permeable membranes allow moisture to dry out of the structure to the outside more easily and more quickly. This is advantageous both during the construction phase and during normal use (if moisture contained in the indoor air penetrates into the structure by diffusion or convection).
As a rule, moisture that arises due to construction work should be able to escape the building structure quickly by ventilation through open windows. Dryers can help to speed up the drying process in wintertime. This helps to avoid permanently high levels of relative humidity.
No ‘tent effect’
The pore-free SOLITEX UM membrane offers particularly good seal tightness against driving rain. The membrane can be installed onto the surface of insulation materials or roof sheathing. A tent effect is reliably prevented by the monolithic functional film and the multi-layer structure. The term ‘tent effect’ describes the phenomenon whereby waterproof tent sheets allow large amounts of moisture into tents at points where they are in contact with inside objects.
