VELUX light tunnel TCR
VELUX light tunnel TCR is designed for flat roofs with a fixed pipe. The recommended length of the tunnels is 0.8 – 6 m between the roof and the ceiling. A 1.7 m long solid tunnel should be used if longer sections are required – in combination with ZTR extension sections – to ensure an adequate level of daylight. It is equipped with 2 x 45 degree bends. It can be extended up to 6 m in length.
The diameter of rigid tunnels is 35 cm or 25 cm. The excellent reflective coating on the inside of the tunnel ensures an internal reflectance of 98%. The easy-to-mount diffuser is supplied with a matte polycarbonate insulation frame. Acrylic or PVC roof dome.
