How to fit Stormproof Hinges

Stormproof hinges are a butt-style hinge commonly used on traditional-style windows to help with weatherproofing. They have 90-degree cranked leaves which help minimise the gap between the window and the frame, thereby protecting the window against the potential damage posed by inclement weather. 

How do you fit stormproof hinges?

Here at G Johns & Sons our experts have prepared this handy step-by-step guide that explains how you fit stormproof hinges:

1. Measure the gap size in the rebate between the sash and the frame when the sash is centralised in the frame 
2. Place the hinges in the desired position, making sure there are 2 per window. 
3. Measure how far to cut the hinges into the frame based on the sash-to-frame gap and the 3mm gap between the hinge plates. 
4. Fix to the frame, making sure the hinge knuckles protrude out of the frame slightly.
5. Mark on to the sash the placement of the hinges, making sure the sash is still central to the frame.
6. Fix the hinge to the sash.
7. Open and close the window to test. Make sure you have the correct compression on the seals and the fastener is positioned correctly and works properly. Make sure there is a smooth movement and there is adequate clearance between the frame and the sash

Do stormproof hinges come in different finishes and sizes?

The standard-size stormproof hinges come in is 65mm x 25mm, which are widely available among good stockists and are usually available in a range of finishes such as black, brass or zinc. 

What type of windows do stormproof hinges fit on?

Stormproof hinges are most commonly used on Casement Windows. The cranked profile of the hinge is designed for use with rebated hinged windows that need to extend over the frame. The offset pivot point allows overlapping stormproof sashes to open without damaging the frame.

How are stormproof hinges manufactured?

Stormproof hinges are made from steel and either electro-plated or powder coated for a durable finish, with high corrosion-resistant qualities. This method of manufacturing means they will keep your windows safe and secure during adverse weather conditions.
