What should I look for in a replacement window?

Focus your efforts on finding windows that have passed a series of tests by one or more independent certification organizations. The materials used to make the window must be of high quality and the method in which the windows are assembled should also be superior. To learn more about buying windows refer to our window buying guide.

What is a Low-E window?

Low-emissivity (Low-E) windows feature glass that has a thin coating of metal on the surface to prevent heat and UV rays from passing though the surface of the glass. The Low-E coating keeps the heat in your home during the winter and out during the warmer months. For more information about Low-E windows click here.

Why is there condensation on the outside of my new energy efficient windows?

This did not happen with my old windows. Exterior condensation on your Low-E glass, Argon filled air space (LEA) windows occurs when the surface temperature of the outside pane of glass falls below the dew point of the air. This condensation usually occurs when there is a warm, humid day followed by quick cooling in the evening. The higher insulation value of the thermopane blocks the escape of the heat from inside of the home so the exterior pane remains cooler. As the sun warms the air, or a breeze blows, the condensation disappears. Consequently, the windows are performing as designed. Based on wind direction and shelter from buildings or trees, only some of your windows may have condensation on them.

What should I do to prepare my windows & doors for winter?

The doors and windows in your home can allow air leaks even when closed. Replacement with new Energy Star qualified windows and doors is advisable, but not always feasible. Before the cold weather arrives you should take steps to inspect and repair any caulking and weather stripping that has deteriorated. If the caulking has visible separation from the joint, remove the old caulking and re-apply, being sure to seal the entire joint. For aesthetic reasons, choose a product that is close to the colour of your house, or is paintable. If the weather strip around your doors or windows appears worn, replacement parts can be ordered from your window & door specialist. Weather stripping comes in a variety of styles depending on the application. Most are very easy to install with self-adhesives or fins that either fit into the window or door moulding or have a flange for screws. The door sweep, the vinyl or rubber fins on the bottom of the door, should make good contact with the threshold to keep out both cold drafts and rain. To reduce interior condensation on your windows during the home heating season, it is recommended that the relative humidity inside your home be between 30 and 50 per cent.

What is the difference between an insert window and a complete window?

An insert window has no exterior brick mould and is designed to sit in the existing wooden frame. It is used primarily in older homes to preserve window interior or exterior casings. Insert windows are less energy efficient but do provide some initial cost savings versus a complete window. A complete window includes the exterior brickmould. This option is most common as it is esthetically more pleasing and is more energy efficient. Complete windows are used when there is rot in the existing wooden frame.

What is Energy Star and what does it mean to me?
