In addition to providing security, energy-efficient doors prevent air and temperature leak from the house. Doors come in a variety of materials, some of which reduce heat flow better than others. Depending on the style and type of insulation, for example, metal-clad doors can be more efficient than solid wooden doors. No matter what the material, ill-fitting doors lose energy and can make your home drafty and uncomfortable.
What to Look For
- Doors made of materials with high insulating values, such as fibreglass, vinyl, or steel.
- Wood, vinyl or thermally broken metal frame.
- Low air leakage rates (for pre-hung door systems).
- Maintenance-free framing materials.
- A high energy efficiency rating or a minimum of double glazing with a 12 mm (half-inch) or greater air space.
Things to Consider
- Make sure that windows, doors and skylights are ENERGY STAR® certified and hire a professional installer to ensure they perform their best.
- Warranties differ from door supplier and type; compare before you purchase.
- Consider the City of Toronto’s Home Energy Loan Program (HELP) as a way to finance your new windows and doors.
- Check with your municipality, utility or retailer to see if there are any rebates available.
