Glass is a beautiful and functional addition to any living space. It can be shaped, coloured and moulded to take on unique looks while also allowing light to pass through. Glass is now more affordable and stronger than ever, making it a popular choice for home and commercial settings. However, glass can be fragile and must be handled carefully to prevent damage. If the wrong methods are used, glass can crack and break, leaving you with an unsightly mess and an expensive repair bill.
Before you start any work with glass, make sure that you and the glazing company both understand how to handle it properly. This is especially important when it comes to window installation. The right knowledge and techniques will help keep your workers safe and ensure a stress-free, smooth installation process.
Preparing for Glass Installation
Prior to installing your new windows, you’ll need to remove any existing window frames and prepare the frame to accept the glass. Double- and single-hung windows have vinyl jamb liners that must be removed to allow the sash to slip out of the frame. To do this, press in on the liners and twist the sash’s top part to release the latch springs on the bottom. Slider windows typically have sliding hardware that simply requires you to pull the interior flip out of the sash and then push down on the exterior one. Both of these windows can be wiped down with a rag soaked in linseed oil to ensure that the putty will adhere.
Once the frame is prepared, apply a coat of linseed oil to the rabbet (the groove where the putty will go) and wipe it down with a rag. Then, roll out the glazing compound into thin ropes that are a little wider than the rabbet’s width. Place the ropes in the rabbet, compressing them and bedding them against the wood to form a narrow bed of putty that will hold your pane.
If your windows are already glazed, use a flat pry bar or a small chisel to remove any old putty and glazing points from the grooves where the glass will rest. Be careful not to gouge the wood and always wear eye protection and thick gloves when working with glass.
Once the rabbet is filled and the grooves are smooth, apply a silicone caulk to the inside of the frame where the new glass will sit. This will seal the gap and protect it from moisture, dirt and insects. It is essential to use a quality silicone caulk and follow the manufacturer’s recommended application instructions. Allow the adhesive to cure for the amount of time specified on the packaging. Then, use a sander or sandpaper to smooth any rough edges and finish off with a clear wood sealer. Once the glass is in place, clamps or clips can be used to secure it until the adhesive sets. Afterwards, the panel can be cleaned with a damp cloth or sponge.
