Solitex Plus is the Next Generation of High Performance vapour permeable Underlay. With an impressive range of characteristics such as high Vapour Permeability, Extreme Watertightness, High Nail Tear Resistance and Thermostability, Solitex Plus offers superior protection against condensation risk and extreme resistance against pelting rain.

Solitex PLUS, from pro clima is a Diffusion-Open vapour permeable membrane, and has received upgraded Irish Agrément Board certification which confirms its performance in all roofing systems, ventilated or non-ventilated, warm and cold roofs and has now also been awarded BBA Certification in the UK.

Solitex PLUS is designed, engineered and manufactured under stringent conditions by pro clima in Germany. When under mechanical stress caused by accidentally stepping on the surface or nailing, the four ply combination of layers, the non slip outer fleece and especially the reinforced fillet material ensures that the product is highly tear resistant so there is minimal damage caused during installation.

The weather-tightness of conventional micro-porous membranes is to a large extent determined by the surface tension of water. If the surface tension is reduced due to conditions which may be found on construction sites, this may reduce the water resistance of the membrane and hence moisture may penetrate the porous membrane.

Solitex PLUS contains a monolithic membrane which employs Closed Cell Technology. Closed cell membranes offer superior weather tightness & at the same time, ensure that a significant amount of water vapour is actively removed from the inside of the building structure & diffused to the exterior. The combination of these two properties is the determining factor when it comes to quality & the safety of the roof construction.

The four ply layer and Closed Cell Technology ensures that Solitex PLUS is the highest performing all-rounder on the market, as it has the best combination of extreme water resistance, high vapour permeability and outstanding physical strength. Solitex PLUS vapour permeable membrane provides the following key benefits:

• Totally resistant to all wood preservatives, wood treatments or natural wood resins
• Extreme resistant to wind driven pelting rain
• Totally resistant to contamination due to on site chemicals
• Extremely Nail-Tear resistant >300N
• Extremely Water-Tight >2500mm

Solitex PLUS, the next generation high performance underslating felt - ensures your roof will be finished to the highest possible specification using the most advanced underslating felt approved by the BBA and the IAB and now available on the market.
