Polytec 50 aluminium clad curtain walling

CWCT tested, REHAU Polytec 50 curtain walling is a composite stick system which offers a cost effective alternative to aluminium curtain walling. We have taken a triple strength approach, combining an aluminium exterior for an attractive design, a steel core for outstanding strength and structural capabilities, and internal PVCu for warmth and low maintenance.

Strength

REHAU Polytec 50 is a cutting-edge curtain walling system combining the properties of PVCu, aluminum and steel. This collaboration creates a triple strength glazing wall system that utilises each material's benefits.

The core of Polytec 50 is made of steel box sections (50 x 40mm to 120 x 40mm) up to 5mm thick. As steel has an E-modulus three times greater than aluminium, Polytec 50's structural capabilities outperform aluminium sections with the same geometry, making it ideal for large spans.

Polytec 50 glazing walls achieve the following IFT Rosenheim Testing:

Water Tightness 1950 Pa (BS EN 12155)
Air Permeability 750 Pa (BS EN 12153)
Wind Resistance 2000 Pa (BS EN 12179)
Safety Test 3000 Pa (EN 13116)
Impact Resistance Pass I5 / E5 (EN 14019)

Thermal efficiency

Glazed facades can span large areas and can therefore be a common source of heat loss. Designed with thermal efficiency as a priority, Polytec 50 aluminium clad curtain walling offers outstanding thermal performance.

Polytec curtain walling can achieve a U_f Value as low as 0.74 W/m^₂K and U_cw Value of <0.8 W/m^₂K which means that less energy is needed to heat and cool a building, this saves money and helps lower the impact on the environment.

Sound rating

REHAU engineers have specifically designed the Polytec 50 curtain walling system to achieve an exceptional sound rating allowing for a peaceful and comfortable internal environment.

At just 43dB, it’s the perfect choice for a huge variety of developments from luxury new builds to large commercial projects

Easy to install

For installation ease, Polytec 50 curtain walling has the same profile acting as both transom and mullion, this helps to eliminate wastage, save costs and gives it another strong advantage over some aluminium curtain walling systems.

Aesthetics

It is a slim system with sightlines at just 50mm, this allows for more view and less window, letting plenty of light into the building. A variety of aluminium caps are available in hundreds of colours which gives flexibility to achieve the wall glazing exterior styling you require.

Polytec 50 curtain walling has a wide range of glazing sizes from 6 – 40mm and a maximum glazing weight of 180kg.
