Envirograf Intumescent Hinge, Lock and Door Closer Protection is a flexible intumescent protection sheet 1mm thick, fitted with self-adhesive backing, and unaffected by moisture. Supplied in standard sizes to make installation quick and convenient. For use behind hinges and steel door closers and completely wrapped around the hidden parts of lock hardware on a fire-rated door. When installed, the sheet compresses without compromising its protective qualities unlike mastic which is ineffective for hinge, lock and door closure protection. The intumescent paper cools the lock, hinges, and screws and protects them from overheating in the event of a fire. Suitable for internal use only.
Also available from this range is a set of three hinges which acts as a complete door closer. Hinges can be individually adjusted, e.g. to latch, the centre hinge can have more tension, and the top hinge can be tightened to allow for buckled door tops. Again, suitable for internal use only. Set of 3 hinges includes screws and Allen keys all availabe in Chrome, White, Brown, Antique Brass, Polished Brass and Stainless Steel finishes.

Hinge, Lock and Door Closer Protection:
Hinges: Remove hinges from both door and frame, cut the cut the Envirograf® intumescent paper to size to size, sandwich it between hinge and rebate on both door and frame then screw the hinges back.
Lock & Keep: Remove lock, cut the Envirograf® intumescent paper to size, wrap it around the lock and sandwich it between the lock and door as you replace the lock. Place paper under the keep plate as well.
Door Closer: Before fitting a door closer sandwich pre-cut cut the Envirograf® intumescent paper between the closer and the door face then fasten the closer to the door. When ordering state the size of intumescent paper required for your door closer.
DO NOT peel off the grey intumescent paper on the back of the hinges: it is an essential part of the fire protection product! Ensure there is a gap of 3.5 – 4mm at the head and closing side and a 1mm gap on the hinge side. Fit the hinges to the door and frame and see whether the door closes without adjustment If adjustment is required, then adjust the top and bottom hinges with the larger Allen key to close the door fully onto the seals without slamming. Then insert the grub screw into the threaded hole and tighten fully with the smaller Allen key. Adjust the centre hinge slightly tighter than the other two hinges to latch Allen keys and screws are supplied with the set of three hinges.
