Windows & Doors
Windows and doors are weak spots that require special attention.
The problem
Windows are one of the weakest points in a house during a wildfire. Direct flames or radiant heat can shatter glass, letting flames and embers inside. Doors (especially wooden ones) can ignite if exposed to direct flames or embers at the bottom gap. Embers can slip through small gaps around frames, weatherstripping, or under doors.
Property Checklist
Gutters and eaves are cleared from leaves, pine needles and other flammable materials
Are eaves enclosed with a soffit made of fire-resistant material?
Do vents have ember-proof metal mesh?
Are gutters and eaves cleaned regularly?
Are gutter guards installed and made of non-combustible metal?
Do downspouts move water and debris away from the house?
Recommended materials
-
Double- or triple-pane insulated glass, ideally with tempered glass on the outside.
Most building codes already require dual-paned windows.
Withstand heat and reduce the chance of breakage from flying embers
Tempered glass is 3-4 times more resistant to heat exposures than normal glass
Added benefits of greater energy conservation and insulation
For maximum fire resistance, there is specialty fire-rated glass, but this is often very expensive
-
Metal or fibre cement (avoid wood and vinyl)
-
Metal mesh or non-combustible shutters
Good alternative if replacing windows can be costly
Fine- meshed metal screen (over the opening of a window increases resistance to the entry of embers into the interior of the home if the window is left open.
Screens reduce vulnerability of the glass to radiant heat exposure.
-
Fire-resistant rubber or metal strips
-
Solid metal, fiberglass, or solid-core wooden doors (not hollow)
