We understand how important it is to choose the correct ladder for an application

To help make that task easier we have summarised key loft ladder technical data for our product range and offer a library of technical drawings (in .dwg and .pdf formats).

Also available are a selection of loft ladder installation and operation instructions.

Furthermore, architects, designers, engineers and industry professionals can download NBS product specifications and BIM objects from NBS Source and download Supreme, Elite and Designo loft ladder objects from Bimstore

Fire Resistance:

Fire Testing and Certification

F30, F30 Plus, F60 fire rated loft ladders with wooden hatches have been tested to DIN 4102 Part 2 by MPA Braunschweig. Copies of the certificates are available upon request. Certifications are based upon testing from below, with the exception of F30 Plus, which is certified for 30 minutes from below and above.

F30, F60 and F90 fire rated loft ladders with steel hatches have been tested (from below) to DIN 4102 Part 2 by IBS Linz. Testing was completed in April 2021 and copies of the certs are expected to be available in June/July 2021. The maximum aperture dimension that could be tested was 1400 mm x 800 mm. We understand that the fire certification will have an allowance that covers larger apertures, but until the certs are available we recommend customers specify and order hatches up to 1400 mm x 800 mm.

EI230, EI260, EI290 and EI2120 fire resistant loft ladders are tested to tested according to ÖNORM 3860, EN 1634-1, EN1363-1. Copies of the certificates are available upon request.

Supreme F30, F60 and F90 steel hatch box construction:

1.5 mm thick steel hatch box with a steel trapdoor. The trapdoor is made from 2 layers of 1.5 mm thick sheet steel infilled with 38 mm of mineral wool to give a 30 minute fire resistance or 75 mm of mineral wool to give a 90 minute fire resistance. There is a 40 mm wide lip to the bottom of the lining around the external edge, which is designed to butt up against the ceiling to help prevent flame and smoke ingress. Similarly, there is also a lip to the bottom of the steel trapdoor, which extends to within 15 mm of the lip on the lining.

For use in fire retardant wooden and reinforced concrete ceilings.

Supreme F30 wooden hatch box construction:

Wooden hatch box and trapdoor are made from fire-resistant B1 chipboard. Suitable for use in fire retardant wooden and concrete ceilings.

MiniLine F30, F30 Plus and F60 wooden hatch box construction:

Wooden hatch box and trapdoor are made from fire-resistant B1 chipboard. The MiniLine F30 and F60 fire rated loft hatch and ladders are suitable for use in fire retardant wooden beams and concrete ceilings. MiniLine F30 Plus fire rated loft hatch and ladder is only suitable for use in fire retardant concrete ceilings.

ProfiLine F30, F30 Plus and F60 wooden hatch box construction:

Wooden hatch box and trapdoor are made from fire-resistant B1 chipboard. The ProfiLine F30 and F60 fire rated loft hatch and ladders are suitable for use in fire retardant wooden beams and concrete ceilings. ProfiLine F30 Plus fire rated loft hatch and ladder is only suitable for use in fire retardant concrete ceilings.

Important – Please ensure that you maintain the fire resistance by filling the gap between the fire rated hatch box and the structural opening with a fire resistant mortar to a depth of at least 200 mm. We recommend mortar class 3 according German standard DIN 18580.
