In Rouen, as throughout Normandy, temperature fluctuations, humidity, and sea winds put homes to the test. In this context, windows play a crucial role in a home's thermal comfort… and in the size of your heating bill. Many Rouen households are still unaware that a significant portion of their energy loss comes from aging or poorly insulated windows and doors.
Replacing your windows is not just a matter of aesthetics or modernization: it's a strategic investment for to sustainably reduce energy consumptionAnd when it comes to high-performance, durable joinery made in France, B'Plast has established itself as a key player since 1989.
In this article, we explain in detail how new windows can transform your comfort and reduce your bills, while highlighting B'Plast's expertise.
Why are your old windows costing you so much in heating costs?
According to ADEME, Up to 15% of a home's heat loss comes from windowsIn Rouen, where winters are often wet and temperatures are cool, these losses are immediately felt in heating consumption.
Several factors explain these losses:
Outdated single glazing
Still present in many older homes, it allows heat to escape almost freely.
Worn or missing seals
They create drafts of cold air, increasing the feeling of a draft and requiring more heating.
Woodwork warped by time
Wood swells, aluminum expands, old PVC loses rigidity: all these phenomena reduce watertightness.
Poor acoustic performance
A poorly insulated window also lets in noise, which can lead some occupants to overheat to compensate for a feeling of general discomfort.
To conclude: If your windows are more than 20 years old, they are probably responsible for a significant portion of your energy costs..
How do new windows improve thermal insulation?
Replacing windows is not simply an aesthetic operation. It's a true technological upgrade.
High-performance double glazing
Modern windows use insulating glazing consisting of two panes of glass separated by a layer of air or argon gas.
Result:
- reduction of heat loss,
- reduction of condensation,
- improved regulation of indoor temperature.
Triple glazing (for highly exposed areas)
Ideal for Rouen houses located on high ground or exposed to the winds of the Seine.

What real impact will this have on your heating bill?
Replacing windows can reduce your heating consumption by 10 to 30%, depending on the initial condition of your accommodation.
A concrete example in Rouen:

- Annual heating bill: €1,800
- Savings after replacement: between €180 and €540 per year
