How to choose my window system?

Up to 25% of heat loss in a home is caused by windows and patio doors, which is why it's important to choose well! The selection of a window’s shape and characteristics – while keeping energy and aesthetics in mind – is very important and remains an uncontested plus in the value of your house.

Take advantage of our tools to guide you in selecting the window type best suited to your needs:

When should I change my windows?

Several signs of wear let you know when it's time to change your windows. Some of the most obvious signs are difficulty opening or closing windows, drafts, excessive condensation or water leaks. Also, rot around a window frame often indicates that it's time to replace your windows.

As a general rule, windows older than 15 years old must be replaced. It's a worthwhile investment, considering the energy savings you'll make through new, more energy-efficient windows.

What are the characteristics of the different models of windows?

Casement and Awning Window Systems
Casement and awning windows open outwards using a crank. The casement window is vertical while the awning window is horizontal.

With their extremely robust multi-chamber profiles for superior rigidity and energy performance, our modular casement and awning window series feature unique characteristics to make them the perfect window!

Sliding window systems
Sliding windows have two openings sliding side to side. The single and double sliding windows series are perfect for tight spaces. They are also known for their excellent value for the money. Narrow profiles allow maximum daylight access and provide unencumbered visibility outside.

Hung window systems
The guillotine window model is among the most popular. Sash windows open by raising the lower half or lowering the top half and can be equipped with one or two movable frames.

The Single and Double Hung Window System is specially designed for high quality remodeling and new construction projects.

Tilt & Turn window systems
Tilt-and-turn windows are powerful multi-function windows. The top of the flap swings inward to allow excellent ventilation while ensuring complete safety when in the open position.

The “La Marquise” Tilt and Turn product line has been developed for the North American residential, commercial and institutional market and designed with a touch of European style.

Consult our guide The Planner to discover the advantages and specifics of different types of windows.

Do you offer windows that meet code standards for emergency exits (Egress)?

We are proud to offer window models that meet the requirements set by the National Building Code (NBC) for bedroom evacuation.

In order for windows to be an adequate means of escape, the NBC requires a minimum clear opening area and that the windows can be opened from the inside without tools or special knowledge.

Contact our experts, they will tell you which window models comply with the Code for Room Exit Outlets.

What is PVC and what are its properties?

PVC means polyvinyl chloride. This plastic is the most popular material for windows. PVC windows are the most economical and are known for their energy efficiency

What is a hybrid window?

The hybrid window offers the best value for the price. It combines the strength and durability of an aluminum exterior finish with the energy efficiency and easy maintenance of interior PVC.

What are the benefits of double and triple glazing?

The main advantage of multiple glass layers is a Low-E (Argon gas) film layer can be inserted In the space between the panes. In Canada, all houses are required to have double glazing at minimum. In certain regions, triple glazing can prove more advantageous to further reduce heat loss, condensation and noise.

What is energy-efficient glass?

Low emissivity glass (Low-E glass) is a clear Thermos glass, double or triple, that can be used with argon gas. Its main advantage is the reduction of energy costs. The insulating properties of this glass help reduce heating costs in winter and cooling costs in summer, by reducing solar energy input.

What is argon gas?

Argon gas is an inert, odorless and colorless gas. It is used in the manufacture of windows to replace air between glass panes because it is an excellent thermal insulator.

What are the benefits of energy-efficient windows?

The energy-efficient window is an essential part of quality homes. Among other things, it makes it possible to significantly reduce heating and cooling costs while ensuring effective control of indoor heating to increase residents' comfort.

Use our Energy Saver Calculator online tool to get an overview of the energy and dollar savings you could achieve with energy-efficient windows.

Why choose ENERGY STAR® certified windows?

All you need to do is to enter the name of the city where you intend to install these windows and a few other details on your residence, and the calculator will provide a total estimate of your annual savings as well as the environmental impact.

What do performance ratings mean (A-3, B7, etc.)?

These performance ratings indicate the performance of doors and windows in the following tests:
A = Air tightness (levels A1 to A3)
B = Water resistance (levels B1 to B7)
C = Wind resistance (levels C1 to C5).

All windows sold in Canada must be rated for these three key performance standards. All of these tests must be conducted in an accredited testing laboratory and are essential to obtain an acceptance number from the Canadian Construction Materials Centre (CCMC).

See The Planner to learn more about performance standards.

What does the ER number mean?

The Energy Rating (ER) number measures the overall energy performance of a window. It is based on various factors, including air tightness and U-value (heat transfer rate). The higher the ER number of a product, the more energy efficient it is. The ER value thus allows you to compare fenestration products in order to choose the most energy-efficient option.

How much do CONCERTO windows cost?

Window prices vary according to model, size and material.

PVC and its hybrid model are the most economical materials.

As an indication, the average market price for a 36" x 48" window (colors and installation not included):
100% PVC sliding window: $360 - Hybrid PVC-Aluminum sliding window: $425

What should I do if my thermos jugs are fogged up?

The average life of thermos windows is 15 years. If your window installation goes back a few years, it is completely normal for them to show certain defects. Contact us to verify if your thermos jugs are eligible for warranty repair.

How can I see the year of production of my windows?

Examine the spacer inside the two glass panes of the window for the year of manufacture. For a casement window, look at the opening sash.

Maintenance

How to properly maintain my doors and windows?

Proper maintenance of your doors and windows will extend their life.

PVC Maintenance:
To keep PVC extrusions shiny for many years, regularly wash your windows with PVC soap or a mild detergent such as an all-purpose cleanser or glass cleaner.

For stubborn stains, here is a list of recommended and non-recommended cleansers:

Recommended cleansers:

  • Any mild soap and water solution
  • Vinegar and water solution
  • Windex® / Fantastik®
  • Murphy’s Oil® soap
  • Lestoil®
  • Non abrasive cleaner, Vim® Gel type

NOT recommended cleaners:

  • Liquid grease remover
  • Chlorine bleach
  • Nail polish remover
  • Furniture polish and cleaners
  • Strong soaps and detergents containing organic solvents

Glass Maintenance:
For cleaning, use commercial products such as Windex® or Fantastik® or mild soap and water solutions or water and vinegar solutions.

To reduce the risk of thermal seal breakage, it is recommended to allow good air circulation near the glass. During very cold weather, do not leave blinds or curtains closed and avoid projecting heat sources directly onto the inside surface of the glass.

Hardware Maintenance:
Clean hardware with a damp cloth. You can also use compressed air. Avoid any ammonia or vinegar products on metal parts. To prolong the good functioning of the mechanisms, remember to annually spray a silicone based lubricant without acetone (Jig-A-Loo® type), on the bolts, hinges, lock points and rubber.

Why does condensation form on the exterior surface of insulating glass units?

Condensation on the exterior surface of insulating glass units is a normal phenomenon that may occur under certain atmospheric conditions. It is caused by heat exchanged between the glass and the surrounding environment. The quality of the glass unit is not a factor.

Under certain conditions (clear night sky, light wind, high humidity), the temperature of an insulating unit’s exterior glass can drop enough so that the humidity in the air condenses on its surface. These conditions may occur several times throughout the year. As soon as the exterior glass warms up, usually early in the morning, the condensation clears.

Under equivalent conditions, less efficient insulating glass units allow more heat to enter than highly energy-efficient units. This heat warms up the exterior glass, making it less likely that condensation will form. Accordingly, condensation is less likely to occur on less efficient insulating glass units. However, highly energy-efficient units help save energy, reduce condensation on the interior glass, reduce the risk of mould on the interior edges of windows, and enhance the comfort of your home year round.

How to remove window mould?

There are several ways to remove mould on window frames, gaskets or silicone:

  • Vinegar
  • Alcohol
  • Anti-mould product
  • Use of a professional

Chlorine-based and bleach-based cleaners are NOT recommended.

To prevent the reappearance of mould, be sure to remove the nets before winter arrives. The screens left on the windows form condensation in the lower corners of the windows which, along with dust, forms a perfect environment for mould growth.
