Frequently Asked Questions

There’s a lot to keep in mind when purchasing new windows and patio doors, so we’ve compiled a list of commonly asked questions you might have. If you need more information, please contact a North Air dealer near you.

Why do old Windows need to be replaced?

There are several factors to consider.

  • Energy loss: Perhaps 25 per cent of your energy bill is lost through windows. A 3’X5′ window with a 1/16″ gap around the sashes is like having a hole the size of a brick.
  • Condensation: Energy-efficient windows stay warmer on the interior surface, so humidity can be raised without getting moisture on windows, which can eventually damage walls. Less condensation also helps reduce growth of mold.
  • Air quality: Tight windows keep out dust, bugs, pollen and sound – so the indoor environment is healthier.

Why should I chose Vinyl?

Vinyl is an excellent option for windows and doors because of its energy efficiency, strength and versatility. Vinyl is resistant to moisture, doesn’t need painting and has a very good insulating value. Wood windows have similar insulating value but they will warp and rot if not painted, resulting in poor efficiency. Vinyl is an attractive low-maintenance option for renovators and homeowners.

Why am I seeing condensation on my windows?

Condensation can be a serious problem. The moisture produced by everyday activities such as cooking and showering shows up first on cool dense surfaces such as windows. Over the long term, this dripping can damage windows and nearby surfaces such as drywall and promote growth of mold, a potential health hazard.

One solution is to reduce humidity but levels can’t always be lowered sufficiently, especially in the winter when moisture is needed to prevent drying.

A better solution lies in the windows themselves. North Air windows feature Super Spacer® technology which boosts window R-values by 30 percent. The advanced warm-edge technology in North Air windows keeps the glass much warmer so they are less likely to fog. Here is some additional information on Condensation.

How do I compare windows?

A great resource to help with Window comparisons is both CSA and Energy Star.

What is Low-e/Argon?

Windows with low E glass are windows built with glass that has been treated to allow low emissivity levels – or those that emit little coldness or heat. These type of windows include those with soft and hard coats, as well as low E film.

Installing energy saving windows with E glass can save you big bucks as far as preventing heat and cold loss from your home, and these savings will far outweigh the initial installation expense in the long run.

A very thin metallic coating in or on the window glass reflects heat and coolness back to its source while blocking some amounts of ultraviolet and infrared light from coming into your house. Energy saving windows that have hard coat E glass are those with an extremely thin layer of tin applied permanently to the glass while it is in its molten state.

Windows with low E film are those in which a thin, transparent low E film has been suspended between two panes of glass. Boasting ultraviolet light blockage of up 99.5 percent, these types of energy saving windows using E glass technology also provide twice the insulation characteristics as that of soft coat E glass.

Low E/Argon can save up to 25% on your yearly heating costs.
