Sound insulation

As regards the acoustic insulation of the façades, the most sensitive element is the windows.

Considering the peculiarities of their constitution (light elements) and the fact that they give rise to discontinuities in the external surroundings of the buildings (forming of joints), the exterior windows and doors represent the weakest building element in terms of sound insulation.

This could theoretically be overcome with a design and constitution of the blind part of the enclosure that would allow to compensate for the lower performance that is admittedly accepted for the exterior windows and doors.

However, in practice, given the ratio of areas and sound insulation (differences greater than 10 dB) between the blind and glazed parts on a façade, reinforcing the insulation of the blind part is not very effective in terms of improvement Of the overall sound insulation of the façade, ie the overall insulation of a wall depends greatly on the insulation of its exterior windows and doors, so the best strategy of raising the sound insulation of a façade is to use solutions with a good insulating power.

The sound insulation level of a window and / or exterior door depends on the following factors:

Type of glass used (surface mass and rigidity)
Fill type used in spaces between glass panels (air or inert gas)
How to fit and fix the glass
Degree of permeability between the rim and the leaf (through seals), being essential to choose typologies of windows oscilo-stop at the expense of sliding windows
Connection between the window and the masonry that supports it
Type of material of sash profiles



CAIXIAVE efficient windows have certain characteristics that give them advantages in terms of sound insulation.
