Frequently Asked Questions

The world of windows and doors can be complex. At Primary Seal we are dedicated to clearly stating what products we offer, the features standard to each unit and the options that are available to you. We seek to answer any questions our customers have, both regarding our products and the window and door industry in general.


What are your windows and doors constructed from?

Primary Seal windows and doors are constructed of vinyl, which is the best overall solution for your windows.

What are the advantages of vinyl windows over to wood or aluminum?

Vinyl offers better energy efficiency which helps maintain consistent temperatures inside your home. Vinyl frames have welded corners, which make it air tight and prevent elements such as water and dust from leaking into your home. Vinyl offers the best protection against air and noise infiltration, which means a more comfortable and peaceful living environment. Vinyl maintains its new look over time, eliminating fading and repainting.

What kind of warranty do you offer?

We offer a 15 years warranty on workmanship 20 years warranty on sealed glazing units and a lifetime warranty on windows.

Where can I get prices for your products?

Pricing on our products can be obtained by filling our online request feedback from or by contacting our head office.

Do you offer installation of your products?

Primary Seal has qualified installers to get the job right the first time on any windows or doors.

Can Primary Seal replicate the look of my current windows?

Absolutely, Primary Seal can manufacture window and door units based on your specifications in order to meet your criteria.

What makes vinyl windows the best choice?

Your choice of framing material goes a long way toward determining the longevity and energy of the total window system. Wood windows possess excellent thermal qualities but are prone to weather deterioration and require painting at regular intervals. Aluminum windows are very durable but offer little insulating value because they conduct energy rapidly. Vinyl windows are your best choice because they offer thermal characteristics similar to wood are extremely durable and provide a finish that is virtually maintenance -free. Keep in mind though, that the best performing vinyl window systems have multi-chambered frames with welded corners.

What is argon gas and why is it used with Low E glass?

Argon is a safe colorless, odorless, non-toxic, non-flammable insert gas. It is used to reduce heat loss in sealed units by slowing down convection in the air space. Commonly it is used in place of air between the glass panes of an insulated Low E glass unit. Argon's heat conductivity is lower than that of air. And thus it is better insulator and contributes to a lower U-factor. Argon is not an effective solar performer by itself and so; it is used on conjunction with Low E insulated glass. Argon gas is a relatively inexpensive option, and can easily recover its cost in heat savings.

What is an INEX spacer and why is it important?

The INEX warm edge spacer is the best performing solution on the market. INEX spacer has a conductivity rate 25 times lower than aluminum spacers. INEX helps to reduce your condensation problems, and also reduces the risk of thermal breakage. When you are planning to construct or renovate, demand the INEX Spacer for your windows and doors and assure your self-comfortable viewing throughout the seasons.

What is the U-factor?

The U-factor or U-value is the measure of a window's thermal efficiency, based on its resistance to the flow of energy. The lower the U-factor, the more thermally efficient the window. Most new window technology had been aimed at lowering U-factors through the use of three important innovations: INEX spacer, low emissivity glass coatings and argon gas.

What is low emissivity glass?

Low emissivity glass, commonly referred to, as Low E. is glass that has been coated with a micro-thin metallic film to improve thermal performance. The coating reduces the transfer of heat rays through the glass while still allowing light to pass through. In essence, the coating reflects heat back toward its source. Thus, heat from the furnace stays inside the home during cold weather, resulting in greater comfort and lower energy costs. Low E coatings also reduce harmful ultraviolet rays that cause drapes and upholstery to fade.

What is the best way to get an estimate for new windows and doors?

You need to have someone come to your home, measure your openings, and show you samples before presenting you with an accurate, no obligation free estimate.
