Double-glazing with polyurethane filling produced by Amel®

This is the innovator product whose properties turn it into one of the most desirable products of current market.


The improved  level of thermal protection is achieved by filling the space inside the profile with rigid polyurethane foam.

It is known that usual profiles have a lower performance compared with double-glazing windows, which is why many companies switched to use bulkier joinery, with a less pleasant design, increased dimensions and a higher price.

The noise protection is very good due to the fact that the rigid polyurethane acts as a sound-absorbing material when the sound passes through the profile so the noise is considerably reduced.

The windows are more rigid due to the hardness of the polyurethane used; windows made of “slim” profiles are as robust as the superior series (which are bulkier and less esthetic).

Sound and thermal protection are two desires of the modern lifestyle. Urban noise invades our intimate space no matter how much we try to ignore it, but the new generation of windows – Double-glazing with polyurethane® – protects us against the noise of the cities.

The price of the energy is steadily increasing requiring a reduction in heating costs without having to purchase expensive joinery systems. The new generation of Double-glazing windows with polyurethane® offers excellent thermal protection at a low cost of ownership.
