Frequently Asked Questions and Answers.
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.
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. This money can be used to finance projects to recondition windows, as well as work related to the sealing of a building envelope. For more information, see the section entitled Grant.
With the exception of those that are seriously deteriorated, most can be reconditioned. Therefore, before proceeding with a window replacement, it is better to check their viability. The Fenestra Group offers an evaluation service that will give you the right information on the subject.
Fees vary depending on the size of a project. However, one thing is certain: most of the time, reconditioning windows costs three times less than buying and installing new ones.
There are very few inconveniences associated with these operations, as the number of employees working in a unit is limited. In addition, the work undertaken generates a minimum of dust and is not noisy.
Restored windows can easily span an additional quarter of a century. In fact, if the completed components are replaced at the right time, a window is designed to last about 100 years.
The Fenestra Group attaches a guarantee of between 5 and 10 years to its work.
This varies depending on the models and the work to be done. The Fenestra refurbishment, whose innovative approach has been the subject of extensive off-site research, has enabled the deployment and improvement of the resulting processes. So much so that today, it usually takes between an hour and an hour and a half to recondition each window of a building.
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%.
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.
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.
Here is a table showing the humidity levels that it is advisable to respect in relation to the outside temperature.
