A roof hatch with a single leaf that includes several innovative features:
The polyisocyanurate insulate board is CFC and HCFC free, ODP zero and has a GWP rating of less than two. The roof hatch has a weather protected exterior push button handle and a smooth action interior handle. All roof hatch detail sizes below are "internal clear opening" dimensions.
The roof door has doubled looped steel tabs that can be securely padlocked from the exterior or interior for added security options. The 343mm roof hatch access upstand has a 102mm base for an easy installation and an integral flashing for weatherproofing. All edges are rounded for safety. The hinges are hardened steel security.
The Roof Hatch door is counter balanced with two fully enclosed, counter balanced compressed gas struts, complete with an integral hold open arm. The roof hatch surface is ready for installation, it does not need decorating. However we can powdercoat in a colour to suit you at an extra over cost.
