A range of premium Steel roof hatches fabricated from 2mm Zintec Steel. Each unit is hand made in the UK to exacting standards and is insulated as well as being fitted with dual EDPM seals (Quadruple seals also available) for excellent weather protection and enhanced air permeability. The lid is fitted with twin gas struts which provide assisted opening. One of the gas struts also locks automatically when fully extended to prevent the lid accidentally closing. This negates the need for an additional stay open mechanism, as well as saving weight and improving aesthetics. Insulation: Twin foil backed 50mm thick PIR insualtion, CFC & HCFC free insulation with an ODP and a GWP rating of zero, thus maintaining the thermal integrity of the building.
Security and opening
The roof hatch lid is secured with hardened steel hinges. Each hatch is fitted with an internal cab lock handle and an external push button so can be opened from either the inside or the outside. Likewise each hatch is fitted with loops which allow a padlock (not included) to be fitted to provide a secure lock either internally or externally.
Standard – The standard finish is primed as photographed – Please note this requires painting with a suitable exterior paint.
Powder Coated We also offer two powder coated options either single (one) colour externally and internally or dual which allows the inside to be a different colour to the outside. Please note our pricing is based on standard RAL colours, special colours may be an additional cost (contact us for details).
Stainless Steel – We recommend this option for high corrosion environments such as any property within 5 miles of the coastline, swimming pools etc. The hatch is made entirely from Grade 316 (Marine) Stainless Steel (including the hinge).
The base of the upstand has a purpose made flashing which gives additional surface area to ensure maximum adhesion with the roof felt. This hatch is suitable for use on roofs up to a pitch of 35 degrees.
The sizes quoted are the internal clear opening measurements. Bespoke sizes available to order
