The importance of proper installation
Did you know that even a high-quality window can lose some of its effectiveness if it is improperly installed?
Choosing high-performance doors and windows is important, but the quality of the installation matters just as much. Improper installation can lead to drafts, water infiltration, and heat loss.
At Derouin Portes et Fenêtres, installation is at the heart of our expertise. We take pride in putting our knowledge and experience to work on every project to ensure careful installation, proper sealing, and optimal product performance.
A carefully completed installation helps ensure a proper seal, improve your home’s comfort, and preserve the energy efficiency of your new doors and windows. Our goal is to provide doors and windows that enhance your home’s comfort and that you can enjoy for many years to come.
Municipal permits
Did you know that some door and window replacement projects may require a municipal permit or approval?
Requirements vary depending on the municipality and the nature of the work. Replacing a door or window with one of the same size and in the same location may be treated differently from a project that changes the dimensions of an opening, adds a window, or alters the building’s exterior appearance.
Special requirements may also apply to heritage buildings or properties located in protected areas.
Our advice: Before starting your project, contact your municipality’s planning department to find out whether a permit is required and what steps you need to take.
It’s always best to check in advance to avoid delays and unexpected surprises!

Door and window maintenance
Did you know that regular maintenance can help extend the lifespan of your doors and windows?
Although modern doors and windows are built to last, a few simple steps can help keep them working properly over the years.
Here are some practical tips:
-Clean glass and frames using products suitable for the materials.
-Clean tracks and mechanisms to prevent dust and debris from building up and interfering with opening and closing.
-Check weatherstripping and caulking periodically for signs of wear.
-Lubricate hardware as needed, following the manufacturer’s recommendations.
-Make sure drainage holes are clear so water can drain properly.
-Avoid keeping your curtains closed all the time. Good airflow around the window helps limit condensation and reduce the risk of excessive heat building up between the glass and the curtains.
Simple, regular maintenance helps keep your home comfortable and allows you to enjoy your doors and windows for many years to come.
Condensation and window fogging
Did you know that condensation on your windows doesn’t necessarily mean they’re defective?
Condensation occurs when moisture in the air comes into contact with a cold surface. In winter, you may notice condensation on the inside of your windows, especially when the humidity level inside your home is high.
Here’s how to tell the difference:
Condensation on the inside of the window: This may be caused by excessive indoor humidity or insufficient airflow around the glass.
Condensation on the outside of the window: This can occur on some high-performance windows when weather conditions are favorable for exterior condensation. This phenomenon does not necessarily indicate a problem.
Condensation between the panes of glass: This may indicate a failure of the sealed glass unit.
Our advice: Maintain an indoor humidity level appropriate for the outdoor temperature and ensure good airflow around your windows. If condensation appears between the panes of glass, have the sealed glass unit inspected.
Understanding the cause of condensation can help you determine whether a simple adjustment is all that’s needed or whether professional attention is required.
Egress requirements
Did you know that certain bedroom windows must provide an emergency escape route?
Egress requirements are intended to help occupants escape in an emergency, particularly in the event of a fire. They establish criteria for certain bedroom windows, both in new construction and during renovation projects.
Depending on the applicable requirements, a bedroom must have an opening that provides access to the outdoors in an emergency. This may apply to bedrooms in basements as well as those on upper floors. If the bedroom has a door that leads directly outdoors, that door serves as an emergency exit.
What requirements must be met?
To serve as an emergency escape opening, a window must, among other things:
1. Be easy to open from the inside, without a key, tools, or special effort.
2. Be accessible, with no obstacles preventing its use in an emergency.
3. Provide an opening large enough for a person to pass through.*
*What are the minimum dimensions?
According to the criteria specified for this type of opening, the window must meet the following minimum dimensions, without requiring the removal of one or more window sashes:
1. Width and height: Neither dimension may be less than 15 in. (380 mm).
2. Clear opening area: At least 3.77 sq. ft. (0.35 m²).
It is important to verify the requirements that apply to your building, as compliance depends on factors such as the current building code and the layout of the space.

Window opening restrictor regulations
Did you know that the height of your windows may require a safety device?
A window’s height in relation to the floor and the exterior ground level can affect the safety measures required. In certain situations, an opening restrictor may be necessary to reduce the risk of falls.
This device limits how far a window can open while still allowing controlled ventilation. Depending on the layout and applicable requirements, other protective measures may also be necessary.
When is an opening restrictor required?
This depends on factors such as the window’s height, its distance from the floor, and the building regulations that apply. It is therefore important to check the requirements before choosing or replacing a window.
Our advice: If your windows are located high above the ground or close to the floor, ask about safety devices suited to your situation. Checking the requirements in advance helps you choose a product that meets your needs while complying with applicable regulations. Tempered glass may also be required.
