Removing commercial glass windows isn’t always straightforward; sometimes it feels like quite a high-stakes job.
Perhaps you’re an office storefront giving a fresh new look or replacing glazing that has been damaged; either way understanding how to remove commercial glass windows correctly is important.
It ensures construction sites are safe, work is done efficiently, and nearby structures remain undamaged.
In this blog post, you will discover top safety tips along with information on the correct tools to use; we will also provide detailed instructions and recommended practices– all designed to make your project go more smoothly!
Why It Matters?
Unlike the lighter, thinner glass typically used in homes, commercial glass windows have unique characteristics.
For example, they may be super thick or have extra layers superimposed– and when it comes time to remove them, there’s often a metal frame or industrial-strength adhesive involved.
If you try to take them out without knowing these things (or how they were put in), there’s a risk of shards flying everywhere– as well as possibly damaging the building’s exterior/walls; plus if someone does get hurt that would be truly awful!
So, let’s learn from a step by step guide on how to remove commercial glass windows!
Step 1: Gather the Right Tools and Materials
Prior to starting your project, make sure you gather everything:
- Personal protective equipment (PPE) is important— think heavy-duty gloves, steel-toed boots, hard hats, goggles, and cut-resistant sleeves.
- Glass suction cups or vacuum lifters specifically made for commercial glass.
- A utility knife with clean blades ready to go.
- Pry bars in different sizes plus flat chisels.
- Something to remove silicone sealant or a suitable solvent/caulking gun and replacement sealants.
- Measuring tape plus masking tape too!
- Perhaps drop cloth/preserving sheets to catch any debris.
Step 2: Establish a Safe Work Zone
It is important to create a safe workspace before beginning any commercial glass window removal project.
- Put up warning signs around the area where you will be working.
- Place drop cloths on the floor to catch any shards of glass that may fall.
- If your work requires you to be above ground level, use either scaffolding or securely fastened ladders.
- Also, make sure there is at least one other person present who can give you tools and help lift heavy window panes.
Step 3: Assess the Window Assembly
In various commercial setups, you might come across metal frames, aluminum channels, or laminated glass panes. Take a moment to see how the window is attached:
- Glazed using continuous silicone or rubber gaskets
- Mechanically fastened with things like screws, clips, or retaining beads
- Bonded with structural silicone (common in curtain wall systems)
Step 4: Score and Soften Sealants
If you want to remove commercial glass window systems, it is important to do so without breaking the glass.
This means that you need to find a way to break the sealant bond. To do so, you need to:
- Run a blade around the edge of the glass where it meets the frame by scoring it with your utility knife– or if you have one, a special sealant cutting tool.
- Put on sealant softener or solvent; follow the instructions on the packaging. Give it some time to work– around 10 minutes is usually enough.
- If there is still silicone sticking around that just won’t give up, cut through it again by rescoring.
Step 5: Pry Out the Glass Pane
Once you have cut the seal, place a flat pry bar or chisel between the frame and glass.
- Go around it slowly as you work your way loose.
- To prevent damage, be sure not to push too hard in any one area!
- When it starts coming away from the frame entirely– this is when using suction lifters/vacuum cups on the glass will give you a much better grip (and make handling safer).
Step 6: Lower and Remove Safely
After grasping the glass firmly, instruct your helper to carefully guide it out of the frame alone, moving backwards as they do so.
- Keep the glass upright to prevent stress from bending.
- Take it over to the designated spot for either disposal or storage.
- Should you wish to keep the pane– for reuse later– position it vertically on an A-frame rack; be sure that there are soft things (like cloth) between them!
Step 7: Clean and Prepare the Frame
Now that you know how to remove commercial glass windows, it’s time to get that space ready for the new glass:
- Use a putty knife or scraper to bid farewell to any leftover sealant.
- Give the frame a good wipe with solvent, removing oils and dirt.
- Take a careful look for corrosion or damage. Fix any issues you find– good as new!
- Finally, apply a fresh bead of sealant that loves the frame, or fit new glazing gaskets like a glove.
Disposal and Recycling
Consider recycling commercial glass. Get in touch with nearby centers to safely dispose of it.
If a pane breaks, be sure to put it in two heavy-duty bags or wrap it in something similar before labeling the package as containing glass so that handlers are aware!
The Bottom Line
It involves careful preparation, using the right tools, and prioritizing safety to know how to remove commercial glass windows!
When you follow these steps, you can prevent harm to yourself and damage to the building. This will keep the building looking good– which might be useful when it comes time to reinstall the glass!
It doesn’t matter if you’re a maintenance pro or an experienced contractor: These guidelines are designed to help make sure that your next commercial glass removal project goes smoothly, from start to finish.
