Solar-control louvres: Tetrix, Equinox, Sunvector

Robustly constructed Tetrix aerofoil fins are a very effective and functional sunscreen and a significant buildings feature. Correctly positioned as a fixed brise soleil, Tetrix fins reduce high-angle solar gain in summer and allow beneficial gains from low-angle winter sun. For optimum effect the louvres can be motorised and linked to the BMS to adjust to changing climate conditions.

Equinox timber louvres shade as nature intended.

Sunvector is a versatile fixed aluminium louvre.

Hallmark has a range of external shading systems; louvre, Venetian, roller and awning. It is now recognised that effective shading is an integral part of the building services and should be part of that package. Hallmark has a series of papers and guidance notes on energy-efficient shading that are available on the Shade Specifier section of the company’s website. These include advice on compliance with Part L,
EU energy directives and CEN standards.
