SLH Roof Hatch with telescopic or fixed runners

Surespan Sliding Roof Hatch


For tall buildings and high wind situations

Surespan SLH sliding roof hatches and sliding glass roof lights provide many advantages over standard roof access hatches. The sliding access hatch is ideal where there is a height restrictions or in areas with high risk of wind. They are also ideal for access to roof terraces via a staircase.

Surespan sliding covers are manufactured with a thermally broken lid and upstand as standard. The sliding mechanism can be sold with fixed rails or internal telescopic rails.

The lid is filled with 50mm of CFC and HCFC free insulation with a U-value of 0.43 W/m²K. Surespan can also provide bespoke solutions such as our glazed sliding hatch over a fixed roof window.

Sliding Types

Surespan can produce two types of mechanism. Telescopic and fixed.

Sliding glazed roof hatch


Telescopic sliding covers are ideal for smaller sizes that only require access for maintenance personnel or end users. These are available in sizes up to 750 x 2500. Perfect for manual operation, the sliding cover easily and smoothly opens to provide maximum clear opening for easy access.

Fixed Rail

Fixed rails are generally used for larger sizes up to 3000 x 3000 however we can manufacture larger sizes in certain circumstances. The fixed rails provide a maximum clear opening ideal for equipment, tools and personnel access. The external rail is fixed down onto the roof and provides structural support fotr the lid.


Sliding roof hatches can be sold with a glazed lid which provides excellent daylight for users below and provides an architectural talking point.

Thermally Broken Extruded Sections

All Surespan SLH Sliding Roof Hatches are offered with thermally broken extruded sections, offering clients excellent energy conservation properties and substantially reducing internal condensation or frost formation.

This in turn reduces thermal conductivity and consequently the heat loss due to heat conduction through the roof hatch frame. Combined with our superior insulation option offering a U-value of 0.20 W/m²K, our sliding hatches can meet most energy efficiency standards.
