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.
Greater protection for metal roofs and facades
Robust structure
The SOLITEX UM connect roofing underlay membrane has a 4-ply structure. Its TEEE functional film is reliably protected between two robust, particularly tear-resistant protective and covering fleeces made of polypropylene.
- In addition, the covering fleece is designed to be water-repellent and provides ideal protection against penetrating moisture.
- It protects the special film that is located underneath it against damage and UV radiation.
- The membrane is glare-free as a result of the anthracite colour of the upper covering fleece.
- The special membrane has a watertightness of over 10 000 mm of water column, i.e. it is watertight even when subjected to strong driving rain.
- The membrane can be exposed to outdoor weathering for three months.
- It can be attached with staples applied only in the protected overlap area.
- The membrane has a noise-dampening effect (less noise from rain falling on the roof).
- It also protects the metal roofing against corrosion on the underside, as all surfaces are in contact with air. The anaerobic bacteria that are responsible for corrosion are avoided.
TEEE functional film watertight and open
SOLITEX UM membranes have a pore-free, closed-cell TEEE functional film that offers particularly good protection against driving rain.
In contrast with conventional roofing underlay membranes where diffusion results from air exchange through a microporous membrane, diffusion occurs actively along the molecule chains in the case of the SOLITEX UM membrane.
With its active moisture transport, the TEEE functional film has extremely quick drying ability, which provides the best possible protection for the membrane against ice formation in winter. Once ice forms, permeable roofing underlay membranes are turned into vapour barriers (ice is impermeable to diffusion) and effectively become moisture traps.
Other particular features of TEEE membranes include reliable protection in the presence of wood preservatives (the membrane cannot be penetrated as there are no pores present) and their particularly high thermostability (melting point of TEEE approx. 200 °C, PP approx. 140 °C). This stability at high temperatures gives the plastic material extremely high ageing stability over a period of decades – even on dark-coloured roofs.
