Pro Clima Solitex Fronta Quattro is a windtight external breather membrane for walls where open jointed cladding will be installed. The plain black non-printed surface provides a pleasing appearance when visible through open cladding. The membrane is extremely stable when exposed to UV and radiant heat from the sun. It can be left exposed during construction for up to 6 months on walls before cladding is installed or as a temporary roof covering before using it on the walls.
Solitex Fronta Quattro is typically used externally over timber frame walls. It may also be used over external wood fibre insulation on Cross Laminated Timber (CLT) walls. The surface is free of any printed lettering and branding so is ideal for installation behind open jointed cladding; where it would be visible through the gaps.
Solitex Fronta Quattro is compatible with open jointed cladding with gaps of up to 35mm. Each piece of the cladding must also be at least three times wider than the gap. The ventilation space between the membrane and the cladding must be at least 20mm.
Solitex Fronta Quattro is extremely robust with a thicker and heavier weight top layer (than Solitex Fronta WA) to offer maximum protection against driving rain, heat from the sun and UV. This is especially importance when used with open jointed cladding systems.
The membrane is fully windtight and breathable. It has a non-porous monolithic TEEE membrane to allow a high degree of outward drying of the building, maximum aging resistance and excellent thermal stability.
Solitex Fronta Quattro can be left exposed to UV and the weather for up to 6 months during the construction phase. Cladding should always be installed. The membrane is not suitable for areas that are permanently exposed to UV or where water collects and runs off repeatedly while being exposed to UV.
Tescon Invis airtight tape should be used for sealing overlaps. This tape is also fully black and UV resistant. It was also specifically designed for use behind open jointed cladding.
Solitex Fronta Quattro’s monolithic membrane means water vapour passes through the membrane via diffusion rather than requiring air movement or draughts to transport vapour through tiny holes in the membrane. Structural damage from condensation is a significant risk when an inferior microporous breather membrane is used instead.
The top surfaceof Solitex Fronta Quattro has a guide for taping and cutting printed along its edge. This will always be covered up by tape when installed. Use Tescon Invis airtight tape, which is entirely black, so the tape cannot be seen through the gaps in the cladding.
Sd value of just 0.05m makes the membrane extremely water vapour permeable.
