Sawtooth rooflights
A sawtooth rooflight, also called a northlight, is a variant of a ridgelight in which one side of the frame section is virtually vertical (with a slope angle of up to 90°). Sawtooth rooflights are ideal in places such as museums, schools, libraries, offices and industrial buildings where the sun should be allowed in more intensively from one direction. It is also possible to fit the sun-facing side of the sawtooth construction with opaque panels.
Arcolux sawtooth rooflights can be glazed with glass or a high-quality polycarbonate. The plastic used is extremely impact-resistant (according to NEN 14963:2006) and hail-resistant and offers good insulation values. Do you want to achieve even higher insulation values? Then a sawtooth rooflight with HR++ or HR+++ glazing is the solution. In combination with thermally broken profiles, insulation values of up to 1.1 W/m²K can be achieved.
Glazing options for the sawtooth rooflight:
- Single-pane laminated glass
- Safety glass
- Fall-proof glass
- Toughened glass
- Occasionally walkable glass
- Walkable glass
- Self-cleaning glass
- Sun-resistant glass
- Insulating glass
- Glass with integrated solar cells (BIPV: Building Integrated PhotoVoltaics)
- HR++ glass
- HR+++ glass
- polycarbonate (PC), solid (single, double or multi-walled)
- polycarbonate (PC), hollow core panel
- acrylic (PMMA), solid (single, double or multi-walled)
- lightproof
- sandwich panel
Integrated protection from the sun
Both the glass and the plastic panels can be given an integrated sun and heat-resistant coating. The glazing material used by Arcolux is virtually 100% UV-resistant.
Glazing with printing
The glass and plastic sheeting can be provided ex-works with full-colour foil prints to create a particularly decorative and unique rooflight.
Insulation
HR+++ glass: U ≤ 0,50 W/(m².K)
PC glazing: U-value from 1,05 W/ m²K
All popular ventilation systems can be used in Arcolux rooflights. From simple, manually operated ventilation vents and grilles to centrally controlled electrical or pneumatic systems for the automatic venting of smoke and heat. See below for an overview of the possibilities. In addition, a ventilation system can also be mounted in a bulkhead.
