FAQ Doors and Windows

What causes condensation on my windows?

Windows can often get moisture or “sweating” by having excess humidity in the air. When the humidity makes contact with the cooler surface of the glass, the “sweating” occurs. This indicates excessive air humidity inside the room which should be reduced. Typical causes of excess humidity are: inadequate ventilation in the room, faulty central air humidifier, heavy drapes preventing circulation near windows. Additional exhaust fans are necessary to prevent “sweating” in washrooms and laundry rooms.

Why replace old windows?

Energy efficiency: 25-30 % of your heating/cooling bill comes from losses of energy through windows and doors. A 3’x5′ window with a 1/16″ gap around the sashes is equivalent to having a hole in the wall the size of a brick. Over the past 10 years windows and doors became much more energy efficient. New windows and doors will significantly reduce your energy bill. Air quality: Tight windows keep out dust, bugs, pollen and sound – so the indoor environment is healthier and more comfortable. Condensation: Energy-efficient windows stay warmer on the interior surface, so air humidity in winter can be raised to comfortable levels without getting windows to “sweat”, which if persistent may damage walls.

Can I use a storm door in front of my entry door?

Storm doors can be used, but SHOULD NOT be used in conjunction with doors painted or stained with dark colors or in areas of high heat or intense sun exposure. We strongly recommend using a vented storm door which allows the trapped heat to escape, prolonging the life and performance of your door. Improper storm door applications can void the warranty on your entry door.

What is insulating glass?

Insulating glass consists of two pieces of glass sealed to a spacer. This creates an insulated air space between the two pieces of glass, resulting in better thermal performance. Insulated glass also reduces condensation while keeping the heat in during the winter, and heat out during the summer.

When should I replace my windows?

When your windows have air leaks and drafts.
When your heating and cooling bills continue to rise.
When your windows are difficult to open and close.
When your windows do not provide adequate security for your home and family.
When your windows allow dust and dirt into your home.
When your windows don’t block outside noise.
When your windows appear foggy.
When your windows are difficult to clean.
When your windows cost you time and money in maintenance.

What is Tempered Safety Glass?

Tempered Safety Glass is treated with high heat for strength. If tempered safety glass is broken, it will shatter into very small pieces instead of shards.
