Frequently asked questions
“Condensation and frost on my windows are creating mold and rotting the frames”
Condensation on windows occurs when the surface temperature of the glass (glazing), sash or frame is lower than that of the humid air around it. The moisture vapour in the air changes into liquid water on contact with these cold surfaces. Condensation will often occur at the edge of the glazing because this is where cold air is more likely to seep through. Condensation can reduce the amount of natural light that comes through the window, affecting visibility, and also cause stains, mould and peeling paint on surfaces near the window.
Energy-efficient windows will occasionally have condensation on the exterior glass surface. This usually happens during periods of warm weather and high humidity near the time of sunrise. Because energy-efficient windows greatly reduce the amount of heat escaping to the outside (which is good during the long periods of cold weather), the exterior glass surface is cool enough to allow condensation to form for a short period of time.
Excessive condensation can be a sign that a window needs some work.
“My heating bills are out of this world. What’s the problem?”
Heat loss through and around your windows is costing you more money than you might think.
“I can’t sit beside some of the windows In my home because of their cold surfaces and drafts”
Cold air entering a house through cracks and crevices around windows is the cause.
“What are the main advantages of investing in my doors and windows?”
• Healthy, comfortable and secire environment for the entire family
• Money saved while helping the environment
• Maintenance-free windows ard doors
• Strong, durable and easily operated hardware with well-balanced mechanisms
• A more beautiful home, both inside an out
• lncrease in property value
“What are the benefits of LOW-E high -Performance Windows?”
Energy efficient windows offer immediate annual savings of 9-18% on home heating/cooling costs.
“What about Humidity and Condensation?”
Energy-efficient windows generate the desired humidity without the condensation. When Humidity is low it can lead to annoying static electric shocks from touching doors or light switches, as well as dry throats and other irritants. Humidifyng the air leads to condensation on windows, reducing visibility and resulting in deterioration of the frame components as well as the growth of mould.
What about Patio Doors?
Sliding glass patio doors are popular and can be energy-efficient if selected on the same basis as for windows.
How efficient are doors?
Air leakage often occurs through front doors and other home entrances. Older doors require regular maintenance to reduce the unwanted air flow.
