Are you a private customer looking for good, reliable, beautiful and high-performance windows?
What if the quality of the window depends above all on the way it is installed, and on the materials that surround it?
MM Montaggi boasts of a great experience in close contact with poorly assembled windows and doors poorly assembled with poor quality materials.
To find out, there are hundreds of customers dissatisfied and disappointed by the usual promises of trusted retailers.
Almost always customers ask us "what are those windows?", Or "XXXXX is a good window", or "YYYYY is a reliable product?"
Not to mention the customers who intend to buy a fantastic window with three glasses and micro ventilation hardware ...
The answer, however difficult it may seem, is not at all;
knowing the quality of the individual components, we are able to evaluate the overall quality of the window by providing an exclusive "ad hoc" consulting service
There are now many extruded profiles on the market, but few remain stable and reliable over time
extreme climatic conditions.
In the case of the PVC window, in addition to excluding most of the deceptive profiles, it is important to take into account the components used for the perfect functioning of the product .
It can have different characteristics becoming deceptive for the end customer!
Finally, we ascertained the total difference and even lack of internal reinforcement with respect to the samples observed by the customer during the estimate phase.
We understand that some retailers show excellent quality profiles, while the customer is sold a product in a different and cheaper configuration than the confirmed one; This is confirmed by the windows with strong dilations, drafts, infiltrations and badly functioning hardware .
It is important to underline the most recent profiles of reduced thickness and / or without adequate reinforcements to favor the thermal transmittance of the window; in fact, they become excessively unstable, especially on hot summer days, today we know how much PVC suffers from large dilations based on surface temperatures.
Boarded chassis due to high surface temperature
Serious boat
(undersized reinforcement)
Dumpster boat
(poor quality PVC mix)
Obvious failure of the upper hinge and the handle
Collection of glazing beads during the winter season
Withdrawal of the profiles and condensation inside the double glazing
Rusty hardware after two years of use
Structural breakage of the PVC frame after 10 years
Failure to seal hermetically due to expansion
LAYING THE WINDOW
As easy as replacing a window may seem, it is not at all.
Removing it takes longer than it takes to install a new one. Initially the windows were zancati and then walled up, which today makes it difficult to remove the old window and risk breaking a large part of the internal and external wall.
DIY DOES NOT WORK
Removing a walled frame costs the customer a small supplement, why risk it?
WHAT HAS CHANGED?
Following numerous disputes and to keep up with the increasingly high-performance windows, it was necessary to take a step forward with the advanced installation materials.
The appraisals indicate a significant withdrawal of the polyurethane foam after a few years of service, while detecting silicone detachments and water infiltrations generally almost always on the lower part of the window without neglecting lateral infiltrations following heavy pouring rains.
Our company has always been committed to personally testing the most modern consumables, in addition to those already on the market known by end customers and professionals in the sector.
We achieved the goal by finding and using personally the consumable material of extraordinary quality, materials resistant to very high temperatures, UV rays, bad weather, standing water, and above all - material guaranteed by the manufacturer for up to 30 years.
We no longer use the obsolete high expansion polyurethane foam, acetic and neutral cross-linking silicones ready to come off after two years ... we use nanotechnological products, because modern windows are technologically advanced and installing them with simple consumable material loses performance characteristics already after a few years.

THE RESTORATION FRAME DOES NOT CONVINCE
Currently the easiest and cheapest way to replace a window is to leave the old wooden frame and hide it with the new PVC, wood, or aluminum frame for restoration.
This method is the method preferred by retailers as almost all the risks due to the removal of the walled frame are eliminated, therefore there are no cracks, detachments or damage to the wall, the price of the installation decreases drastically.
In addition, this method greatly simplifies the installation of the new window because there is no need to waste time planning the installation. The application of the PU foam is foreseen on the three sides between the two frames to then hide everything with the joint covers.
The lower side of the old wooden frame must almost always be eliminated in this way the whole frame becomes even weaker.
The video demonstrates the weakness and condition of the wooden frame;
The next step is the fixing of the new restoration frame by means of concrete screws without dowels, it is clear that the whole structure remains unstable, without considering the drafts that can be created in the cavity of the old frame (part between frame and non-insulated wall).
