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. These are available in a multitude of options.

Sliding glazed roof hatch


Glazed sliding rooflights are a beautiful alternative to our standard aluminium lids allowing further light into the room below and provides a suitable product for access onto roof terraces. See specail features below for more alternatives.


Electrically operated sliding hatches can be glazed or aluminium and provide a single button opening of the lid. Control centre provides use of wall mounted push buttons, key turn switch and connection to FAS/BMS Management system. Also suitable for daily air ventilation

Double Leaf

Double sliding lids can be telescopic or fixed for larger sliding hatches and provide perfect means of plant access with equipment and personnel use. These are ideal combined with electric openers. And provide maximum clear opening.

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.

Thermally Broken Sections

Solar Powered Roof Hatches

All Surespan electrically operated roof hatches are available using solar technology, offering clients an environmentally friendly alternative.

A 12V solar panel is fitted either onto or nearby the roof hatch, harnessing solar energy to charge it's batteries and allowing the hatch to automatically open and close using a completely wireless system. This can be operated by either a wireless switch or remote control. It's batteries are fitted with a conditioned monitoring feature which sounds an alarm if they are running low or indicate a fault.

Additional options including being linked up to the building's Fire Alarm System (FAS) or Building Management System (BMS) are available. Multiple roof hatches can be operated by one solar panel.

This technology can also be applied to Surespan's SRHG glazed roof hatches.
