Frequently Asked Questions and Answers.

What is the value of a refurbished window in terms of energy efficiency?

The Fenestra refurbishment achieves very high performance in terms of energy efficiency. In fact, it allows an airtightness equal to or even greater than several types of windows on sale on the market. Thanks to the technologies currently available, the Fenestra Group can also increase the thermal resistance of certain glasses.

What does financial assistance cover?

In case of eligibility for one of the available financial assistance programs, the amounts granted generally vary between 8% and 20% of the cost of a project.

What proportion of energy is saved by sealing a building envelope?

Studies have shown that 20% of energy losses are related to poor insulation. In addition, another proportion, which reaches 40%, is caused by air infiltration and exfiltration. The sealing proposed to remedy this allows a clogging of said air infiltrations. Depending on the nature of each project, the energy savings generated vary between 3% and 20%.

How to spot air loss in a building?

They are detected by various tests, including blower door, smoke or infrared cameras. The openings and holes discovered are then analyzed and quantified, allowing an accurate measurement of the energy losses they generate.

I noticed that condensation formed on the glass of my windows. How to prevent this phenomenon?

In any season, it is recommended to have a maximum humidity level of 40% inside the house. Avoid contact with paint, stain or solvent with weatherstripping, PVC and window hardware. Ventilate rooms regularly to lower humidity. In addition, open curtains and/or blinds to promote air circulation.
