Spacious and more light

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.

For stringent requirements in areas such as impact resistance, insulation or fire safety, you’ve come to the right place at Arcolux. Our aluminium constructions with glass or plastic are tested according to the following Dutch and European standards:


Glass:

NEN 2778: methods for determining the watertightness, rainproofing or structural constructions.


Plastic:

  • Air permeability (NEN 1026:2000)
  • Watertightness (NEN 14963:2006)
  • Upward load (NEN 14963:2006)
  • Downward load (NEN 14963:2006)
  • Soft body impact 350/800/1200 Joules (NEN 4963:2006 and NF.P.08.301 and NF.P.08.302 and NF.P.08.301 and NF.P.08.302)
  • Hard body impact (NEN 14963:2006)
  • Fire spread resistance (EN 13501-5)


Glass & plastic:

The designs and constructions are realised on the basis of:


Eurocode 0 Basis

  • NEN-EN 1990: Basis of structural design


Eurocode 1 Actions on structures

  • NEN-EN 1991-1-3: Snow loads
  • NEN-EN 1991-1-4: Wind loads


Eurocode 9 Design of aluminium structures

  • NEN-EN 1991-1-1: General rules
