Before we start replacing the glass, we need to prepare the necessary tools and materials.

Gloves & Safety Glasses--Prevent glass fragments from injuring people

Putty Knife--Remove old glazing tape

Glass Cutter--Custom-cut new pane

Cleaner -- Clean window frames

Adhesive or sealant--Seal the glass after fixing it

Safety first,wear your safety glasses and gloves to protect yourself from scratches caused by glass fragments or tools.

Move fragile items around and lay down old newspapers or plastic sheets to protect the floor.

Then wipe the area by the window frame so no debris or dust remains on the surface.

Note the window's construction and see how to install new glass.

Gently tap the old glass edges with a scraper and soft tool until loose, then lift it out carefully.

When cleaning up broken glass, take preventive measures to avoid injury from sharp and tiny pieces of glass.

Screw fixation: Release the screws on the edge of the window frame and remove the bead/fixing frame using a screwdriver.

Clip-On Type: Use a tool such as a screwdriver to gently pry open the catch and slowly loosen the glass edge.

Glass adhesive strip: Remove with a utility knife or scraper, so as not to scratch the window's aluminum frame.

If the glass breaks in one piece, use strong tape to secure it on both sides to keep the pieces from scattering.

Then hold the glass on both sides and tilt it outward to remove it.

For large and heavy glass, you can use a suction cup to help secure it and remove it slowly.

If the glass is cracked but not fully broken, carefully remove the pieces one by one to avoid putting too much pressure on it. This helps prevent the whole thing from shattering.

Then, use a heat gun to melt the old glue and carefully peel it off with a spatula.

Finally, we can use a vacuum cleaner to clean the glass fragments in the groove of the window frame.

Use the prepared cleaner to remove the glue stains and ensure that the new glass fits smoothly.

Before replacing old glass, measure the height, width, opening, and thickness of the old glass.

Then order a new piece of glass from the manufacturer that matches the dimensions of the old one.

You can order large pieces of glass and cut them to size yourself.

Then, carefully put the new glass into the window frame. Hold it steady and make sure the edges line up properly.

Screw fixation: Reinstall the pressure strip and tighten the screws evenly.

Note that over-tightening will cause stress cracking of the glass.

Clip-On Type: Press the snaps into place one by one to ensure that the glass firmly fix around.

Glass adhesive strip: Insert the new adhesive strip into the groove of the window frame and fit the edge of the glass.

After installation, evenly apply sealant along the edge of the glass to prevent water seepage or air leakage.

We can use a scraper to smooth the adhesive surface and remove excess adhesive.

We can push the glass gently to check if it is stable, without shaking or unusual sound.

Then,clean up the work area, put away tools, and dispose of waste materials.

Wait for the sealant to cure completely, and avoid touching or opening the window for 24 hours.
