What is the best thing to cover a broken window with?

Quick Answers

There are a few good options for temporarily covering a broken window, depending on your situation:

– Plywood – Sturdy and weatherproof, can be cut to size and screwed into window frame.

– Plastic sheeting – Lightweight and inexpensive, use heavy duty plastic secured with tape or staples.

– Window film – Special thick plastic films cling to glass and keep out drafts.

– Plexiglass – A rigid and durable plastic material that can be securely mounted over the window opening.

– Tarp or heavy fabric – For a quick fix, use a tarp or blanket secured around the window frame.

The best solution will depend on factors like window size, severity of damage, time frame for replacement, budget, and desired level of security and protection from the elements. Plywood, plastic sheeting, and plexiglass provide more durable and secure protection.

Assessing the Damage

When a window breaks, the first step is to assess the damage. Here are some key things to look for:

– Size of broken area – Is it a single crack, a hole, or the entire window pane? Larger areas will require more patching material.

– Sharp edges – Broken glass can have sharp, dangerous edges. Wear protective gloves when handling broken window panes.

– Cause of damage – Was the window struck by an object, warped by weather or old age, or broken by intruders? This can inform the repair solution.

– Frame damage – Are the window sash and frame still intact or also broken? The frame provides critical structural support.

– Security concerns – Is the broken window leaving your home vulnerable to intruders or animals? Prioritize materials like plywood that offer security.

– Weatherproofing needs – Is the window broken during mild or inclement weather? Cold, rain and wind will require more impermeable materials.

Assessing these factors will help determine the best patching approach and materials for covering the broken window safely and effectively.

Temporary Covering Options

Here are some of the most common temporary coverings used for broken windows and the pros and cons of each:

Plywood

Plywood is a go-to option for securing damaged windows.

Pros:

  • Inexpensive and readily available
  • Durable and weatherproof
  • Provides security – difficult to penetrate
  • Easy to cut to size
  • Can be screwed into window frame for sturdy mount

Cons:

  • Heavy and unwieldy in large sizes
  • Some aesthetic appeal
  • Needs to be painted to prevent weather damage
  • Not transparent

Plastic Sheeting

Plastic sheeting or polyethylene film can also cover windows temporarily.

Pros:

  • Lightweight and easy to transport
  • Low cost
  • Easy to cut to size
  • Transparent – doesn’t block light

Cons:

  • Less durable than plywood
  • Can warp and peel away over time
  • Lower security – can be cut with knife
  • May require tape, adhesives, or fasteners to properly secure

Window Film

Specialty window films are designed to cling to existing glass.

Pros:

  • Designed specifically for glass coverage
  • Extra thick and durable plastic
  • Keeps out drafts
  • Some provide insulation
  • Transparent

Cons:

  • More expensive than plastic sheeting or plywood
  • Less secure than rigid materials
  • May be difficult to properly install
  • Visible aging over time

Plexiglass

Plexiglass (acrylic) sheets are secure and sturdy.

Pros:

  • Very durable
  • Weatherproof
  • Transparent
  • Can be cut, drilled, and mounted like glass
  • Provides security

Cons:

  • More expensive than other options
  • Heavy in larger sizes
  • Prone to scratching
  • Not effective for hole coverage

Tarps or Fabric

For quick fixes, tarps or fabric can cover broken windows.

Pros:

  • Inexpensive
  • Quick and easy to hang up
  • Good for temporary protection from weather
  • Lightweight

Cons:

  • Very weak security
  • Susceptible to wind, rain, and weather damage
  • Not transparent
  • Could blow away or fall down if not properly secured

Installing Temporary Window Covers

Installing a temporary window cover properly is important for security, weatherproofing, and safety:

Plywood

– Measure window and cut plywood at least 1/2 inch larger than the window on all sides
– Drill holes through the plywood and window frame to accommodate exterior grade screws
– Place plywood over window and screw it securely into the frame
– Caulk or weatherstrip any gaps between the plywood and frame
– Consider painting to protect the wood from water damage

Plastic Sheeting

– Measure the window and cut plastic sheeting several inches larger than the frame
– Clean the window frame so the tape or adhesives stick
– Attach plastic to interior side of window using duct tape, double-sided tape, or staples
– Seal all edges with tape and create creases at the corners to reinforce it
– For larger windows, apply vertical and horizontal strips of wood to strengthen the plastic

Window Film

– Thoroughly clean the glass and allow to fully dry
– Measure and cut the film to size based on the manufacturer’s instructions
– Remove any backing from the adhesive and apply to window glass
– Use a plastic smoother to carefully remove any bubbles or wrinkles
– Trim off any excess film around the edges

Plexiglass

– Measure the window pane and cut the plexiglass to size
– Drill holes through the plexiglass aligning with the window frame
– Place the plexiglass over the window and screw it into the frame securely
– Caulk around the edges to create a weatherproof seal
– Plexiglass for larger windows may require additional brackets or supports

Tarps or Fabric

– Measure the window and cut fabric at least 12 inches wider and taller than the frame
– Attach temporary fasteners, tape, staples or clamps to affix fabric to interior window framing
– Pull fabric taut across window, eliminating any sagging and gaps
– For better weatherproofing, apply plastic sheeting behind the fabric
– Check frequently to ensure fabric remains securely fastened

Longer Term Solutions

For broken windows expected to remain for more than a few days, temporary repairs should be followed up with more permanent solutions:

Replacement Glass

The most complete fix is to have the broken glass pane replaced by a professional glazier. This will restore the window to normal function.

Window Pane Kits

DIY window pane replacement kits allow you to cut and insert a new pane of glass or acrylic. Professional help is recommended.

Call a Contractor

A general contractor can make structural repairs if the window frame or surrounding walls were also damaged.

Replace the Window

For old or severely damaged windows, a full replacement window installation may be needed. This is best left to professionals.

Plywood or Plexiglass

For certain situations, plywood or plexiglass may work as longer term solutions if properly installed and sealed.

Conclusion

Covering a broken window properly depends on the type and extent of damage, weather conditions, timeline, budget and personal preferences. Plywood boards provide maximum security and durability at low cost. Plastic sheeting and window film offer transparent light passage, while plexiglass gives security with visibility. Tarps are a quick and cheap short-term option only. For repairs longer than a few days, glass or full window replacement is best. With some basic DIY skills and safe installation, temporary window covers can buy you the time needed to arrange for suitable permanent repairs.
