TYPES OF MATERIALS AND THEIR ADVANTAGES
Here’s a useful table showing the various types of materials available on the market. Whether you’re looking for PVC, a PVC-aluminum hybrid or aluminum, you’ll be able to make an informed decision.

The choice of PVC
Opting for PVC windows means choosing excellent value for money. There’s a reason why it’s one of the most popular choices these days. PVC (polyvinyl chloride) is a resistant material, which offers good thermal and acoustic insulation while requiring little maintenance. It is ideal for those looking for a durable and affordable solution.
The advantages of PVC
By opting for a PVC frame, you are sure to make a good choice. Here are the advantages of this solution:

INSULATION & PERFORMANCE

The new Energy Star specifications effective January 1, 2020 are much more stringent, the approval of a product is now reserved for the top 20% of the most energy efficient products sold in Canada.
A product that does not meet the new ENERGY STAR criteria will not be a poor quality window, it will simply no longer be part of the top 20% of the most energy efficient products on the market. Triple thermoses, products without tiles or false crosspieces and fixed products are therefore favored by the new standard.
Finally, there is only one climate zone for all of Canada after January 2020 (instead of 3) and only products that meet the Climate Zone specifications.
Energy efficiency: R-value, U-factor and EP rating
Product | Maximum U-factor W/m2 (Btu/h*pi2*F) | OU | Minimum energy performance (EP) |
Doors and windows | 1.22 (0.21) | 34 |
Minimum values for meeting the new Energy Star requirements.
To help you make an informed decision, here are the characteristics that ensure that a window provides good insulation:
R-value
This designates the insulating properties or thermal resistance of a material or product. The higher the rating, the better insulation the product provides.
U-factor
As an indicator of the resistance to temperature fluctuations, the U-factor is, in fact, the inverse of the R-value. You should look for the lowest possible number.
EP rating
The EP (energy performance) rating is calculated using a formula that establishes a balance between a product’s U-factor, solar heat gain coefficient (SHGC) and air leakage. The higher the EP rating, the more energy efficient the product will be.
WHICH GLAZING TO CHOOSE ?
Here’s some useful information and advice on energy efficiency and sound absorption options to help you make an informed decision.
Double glazed window
Double-glazed windows are the most attractive value for money solution on the market today. It consists of two panes of glass separated by a layer of air or gas enclosed between them. This structure is designed to improve the thermal and acoustic insulation of windows.
It is interesting to know that triple glazing is not necessarily more soundproofing than double glazing. In fact, it is the thickness of the glazing that has a greater influence than the quantity of glass. Thus, double glazing with two different glass thicknesses will be more soundproofing than triple glazing with three identical thicknesses.
There are several possible components between the two panes that can impact the performance of your glazing.

Argon gas
Argon gas is an inert gas used between the two panes of double-glazed windows to improve their thermal insulation performance. Colorless, odorless and non-toxic, argon is an excellent insulator, helping to maintain a stable indoor temperature by limiting heat loss in winter and heat gain in summer. In recent years, we have also seen a new type of gas arrive on the market: krypton.

Low-e film
The Low-E film acts by blocking part of the infrared rays (responsible for heat) while allowing visible light to pass through. This will keep a house cooler in summer without blocking light and provide better thermal insulation in winter by returning heat to the interior.

Triple glazing
This type of glazing is the next trend in standards. Made up of three walls, a triple-glazed window has two air spaces, one more compared to double glazing. Thus, this type of glazing provides better thermal insulation. Depending on the thickness of the glazing, this type of solution can also offer an excellent sound barrier.


Soundproofing
According to popular belief, triple glazing has greater sound-proofing power than double glazing. This belief is false: the difference in thickness of the glass panels will have an impact on the sound passing through them, since they will be able to cut off groups of different sound waves. Thus, double glazing with two different glass thicknesses will be more sound-absorbing than triple glazing with three identical glass thicknesses.
FINISHING ELEMENTS
Once you’ve determined the type of window, material and glazing you want, it’s time to choose your finishes. Depending on your previous choices, you will have more or less possibilities. At Portes et Fenêtres Verdun, we have a wide choice of finishes for all of our models. Here are the possible elements.

Choose the color of your windows
A chart of several standard colors, the most popular, to match flashings, gutters and soffits, is available. Check with your representative. To choose the color of your windows, it is essential to take into account several elements such as the architectural style, the visual harmony of your facade and the climate. Traditional homes, for example, go very well with classic shades like white or natural wood, while modern designs lend themselves better to dark or metallic colors, like charcoal gray.
The other elements of your facade and exterior elements, such as roofs or shutters, can influence your choice to maintain visual coherence. Finally, remember to check whether certain local regulations come into force. Unfortunately, you are forced to comply with these rules which may leave you little freedom in terms of choice.

Integrated grilles
Tiles are a very popular decorative element. It comes in various styles, in Georgian or rectangular profile and is located between the two glasses of the sealed or thermos unit.
Superficial grilles
SDL tiling allows you to reproduce the effect of the lattices of the first windows at the beginning of the colony. Nowadays, it is generally made of aluminum or PVC and can have a classic or more contemporary look, in several colors, usually white or black.
It should be noted that products without tiling or false crosspieces and fixed products are therefore favored by the new Energy Star standard.

Cranks
Portes et Fenêtres Verdun is proud to offer its brand new unique, strong, durable, easy to handle, superior quality products from the Vesta series from the new Premium Interlock system, Assa Abloy for casement and awning windows. The tests carried out demonstrated increased resistance of this new technology, far exceeding industry standards. The operation of standard cranks is generally tested 8,000 times on the market, while the innovative Assa Abloy system is validated over a cycle of more than 32,000 operations.

Locking
The new Assa Abloy multi-point window locking system makes the movement very smooth.
Brick moldings
They are added to the frames on the outside. In different widths, models or profiles, these moldings add style to your home, they adapt to the dimensions of the openings and the exterior cladding of the building. You have the choice between contemporary style or more classic style moldings.
High-performance hinges
Assa Abloy hinges used on awning and casement windows can support up to 148 lbs., well exceeding the industry standard of only 96 lbs.
Screens
Screens are always included with operable windows. Made of fiberglass wick, they can cover the entire window or not, either single or double. Screens for sash and sliding windows are installed on the exterior and are best removed for the winter. The screens on crank models can be left in place since they are installed inside.
HOW TO MEASURE YOUR WINDOWS ?

To measure your windows correctly, start by measuring the width by taking three horizontal measurements: one at the top, one in the middle, and one at the bottom of the interior opening of the frame. Note the smallest of the three dimensions to ensure the new window fits correctly in the space, without risk of jamming.

Next, measure the height in the same way, taking three vertical measurements: one to the left, one to the center, and one to the right of the interior frame. Also keep the smallest of the three measurements.
Finally, take the depth of your frame by checking the thickness between the inside and outside of the frame. This measurement is important to ensure that the new window fits well into the existing depth, especially if roller shutters or blinds are already in place.
Don’t forget to take into account the direction of opening seen from the outside.
WHAT IS THE PRICE OF A WINDOW ?
Whether purchasing a window for new construction or replacing it, the price of a window can vary widely. The choice of materials, the quality of the components, the finishes and the dimensions will have a large impact on the final sale price. When making a quote, we know that a low quote is always more attractive, but you must check that the cheaper quote contains all the elements, of the same quality, and therefore comparable.
