Double & Triple Custom Windows

Glass panes are the largest area of any window and the most vulnerable to heat loss and gain. To provide adequate thermal performance and save up your money on energy bills, a minimum of 2 panes are required. Traditional 7/8″ double glazing options are used and can accommodate 1-1/4″ for all custom windows.

In areas with a harsh climate, triple pane custom windows can be especially profitable. Ecoline triple glass packages qualify for high energy-rating standards with 1-3/8″ and 1-1/4″ options available. It can be used in combination with gas injection and/or LoE glass coatings but are not necessary.

F.A.Q.

Basically, a custom window is a unit specifically manufactured for your opening and customized with preferred functions and options to match your house exterior perfectly.

The benefits of custom windows are apparent – they bring more value to your house, being specifically made to match your exterior/interior and rough openings.

Custom windows are usually more expensive than stock windows. But the final quote depends on multiple factors – custom sizes, colours, frames, glazing and custom window installation.

It is a stock window with vinyl frames that are often used for new constructions or replacement projects.

A window with 40×52 size is a pre-designed stock window that stands for 40 inches wide and 52 inches high for rough opening.
