5 Ways: How to Cover a Broken Window in a House
When glass gives way, you’ve got two major concerns—keeping the weather out and keeping everything else in. Melbourne’s climate doesn’t hold back, from stormy squalls to blazing sun. So, it’s vital to use materials that can handle the conditions.
Below are some of the best methods to cover your broken house window, whether it’s for a few days or a couple of weeks. Each option is strong, weather-sensible, and totally DIY-friendly.
1. How to Cover a Window with Wood (Plywood Board-Up)
First up on our list of how to cover a window, we have the good old trusty wood material.
Best for: Storm protection, break-ins, renovations, or smashed windows
Why it works: Withstands strong winds, rain, and impact from debris— If you’re in a windy or remote area around Melbourne, this is your best bet that offers excellent strength and weather resistance.
Materials Needed:
- Plywood (at least 12mm thick)
- Measuring tape
- Saw
- Screws or nails
- Drill or hammer
- Weatherproof tape (optional)
Steps:
- Measure the window opening and add 5 cm on all sides.
- Cut plywood to size.
- Drill pilot holes in each corner of the board.
- Screw or nail the board into the window frame or surrounding wall studs.
- Seal edges with weatherproof tape if needed.
2. Foam Insulation Board
Best for: Blocking heat, cold drafts, or noise temporarily
Why it works: Provides thermal insulation against both summer heat and winter chills; ideal for southern states or inland regions. It’s a quick fix that’s light, and keeps your room comfortable—especially great during Melbourne’s chillier spells.
Materials Needed:
- Rigid foam insulation board (XPS or EPS)
- Utility knife
- Measuring tape
- Duct tape
Steps:
- Measure the window frame.
- Cut foam board to fit snugly inside.
- Push board into the opening.
- Seal the edges with duct tape to reduce airflow.
3. Tarp and Bungee Cords
Best for: Covering windows during storms or building repairs
Why it works: Heavy-duty tarps resist UV damage, rain, and wind—great for emergency weather protection for big openings or when you need to cover up fast before a storm hits.
Materials Needed:
- Heavy-duty, waterproof tarp (UV-resistant)
- Bungee cords or rope
- Grommets or hooks
- Hammer and nails (if needed)
Steps:
- Select a tarp large enough to cover the entire opening.
- Drape it over the window and align the grommets with wall edges.
- Secure using bungee cords or tie to hooks/nails.
- Pull the tarp tight to prevent flapping in the wind.
4. Thick Plastic Sheeting (Builder’s Plastic)
Best for: Temporary weather barrier, especially during renovations or repairs
Why it works: Ideal for keeping out rain, wind, and dust; UV-stabilised plastic resists sun damage. A solid choice for home projects or in-between glass replacements. This method is affordable and surprisingly tough enough to protect your home as you wait for Melbourne window glass repair experts to arrive.
Materials Needed:
- Builder’s plastic sheeting (200 microns or thicker)
- Scissors
- Duct tape or staple gun
- Measuring tape
Steps:
- Cut sheeting 10 cm larger than the window on all sides.
- Place over the window opening.
- Tape or staple all edges securely to the wall or frame.
- Reinforce with extra tape for wind resistance.
5. Temporary Window Film
Best for: Sun protection, privacy, and heat reduction when the glass is still intact
Why it works: Blocks harsh UV rays and reduces indoor temperature during hot Australian summers. If the glass is cracked but still there, this is a neat way to shield your home and keep the glass in place while waiting for professional repair.
Materials Needed:
- Static cling or adhesive window film
- Spray bottle with water
- Squeegee
- Scissors
Steps:
- Clean the window thoroughly.
- Cut the film to size.
- Spray the window with water.
- Apply the film and smooth out bubbles with a squeegee.
6. Cardboard Panels (Indoor Only)
Best for: Quick, temporary indoor coverage when other materials aren’t available
Why it works: Effective in dry climates or urban areas for blocking light and offering minimal heat insulation. While not as tough as other methods, it’ll do in a pinch—just make sure the weather’s calm.
Materials Needed:
- Large cardboard sheets
- Scissors or box cutter
- Duct tape or masking tape
- Optional: plastic sheeting overlay
Steps:
- Cut cardboard to fit the window opening.
- Press it into the frame.
