Laminated glazing, standard double glazing, soundproof double glazing... In addition to airtightness and watertightness, thermal insulation is today a major criterion of choice.
This thermal performance is characterized by the coefficient Uw, expressed in W / m².K. The lower it is, the more the window is insulating.
Currently, a powerful window has double glazing (even triple glazing). Depending on the model, thermal performance can vary widely.
Standard double glazing
The standard 4/16/4 double glazing traps dehumidified air while double glazing with reinforced thermal insulation contains a neutral gas (argon or krypton) and low emissivity films.
Double glazed phonic
10/10/4 glazing offers enhanced sound insulation.
This window consists of a first glazing 10 cm thick and a second of a different thickness (4 cm). This asymmetrical double glazing thus limits the propagation of sound waves.
4 + 4/12/4 laminated glazing blocks burglary and intrusion thanks to transparent dividers.
The desired performance depends on the desired level of comfort, but also your budget.
