Mardome Trade - Fixed Dome with sloping kerb, Auto Vent, 600mm x 600mm

These roof-lights access hatches are supplied as a cellular PVC kerb and a pre-drilled glazing unit allowing the installer to screw fix the glazing to the kerb. The pre-drilled fixing holes are positioned using state of the art cutting technology ensuring a reliable and accurate fit every time.

Once installed, security caps encase the fixings for additional security. The security caps are designed to improve waterproofing and reduce the likelihood of forced entry through the roof-light. The security caps are extremely difficult to remove after installation.

They are available in single, double or triple skinned options. 

Access hatch opens to 90 degrees.

The single skin is only available in a clear tint.

The U Values (insulation) are:

• single skin 5.7 W/sqm.K
• double skin 3.0 W/sqm.K
• triple skin 2.0 W/sqm.K

The kerb is designed to provide exceptional waterproofing integrity. Water ingress is virtually impossible as the waterproofing membrane can be applied to the full kerb height and finished on the top horizontal surface.
