ASTRA ROGER'S RECCOMENDATIONS FOR BUYING PVC WINDOWS OR PVC AND ALUMINIUM JOINERY WITH THERMOPANE GLASS
For the PVC windows you want to but to give you maximum satisfaction, after mounting, the joinery must fulfill all the necessary quality standards. That is why your PVC joinery must be designed according to your requests. It must also benefit of a quality construction precess, but also a professional fitting.
Thermopane design (that is PVC or aluminium, or aluminium wood joinery, windows, doors or accesories) will be correctly made when the designer takes into consideration all the elements that define the joinery: the right opening type, according to the joinery's destination, the correct type for the themopane glass, according to the thermal, sound insulation standards and profiles' type. All of this must be done taking into consideration the colour or mechanical resistance.
Do not buy products without prior conclusion of a contract and without charge! Without these, you can't get a warranty, and in case of any claim, you will remain without legal cover.
After you will be assured that the PVC and aluminum windows with low-emissivity glass have exactly the right configuration and appropriate materials and their construction is executed on a corresponding line, for a professional complete mounting, the PVC windows need to be installed by qualified technicians.
Professional installation of the windows starts from taking measures to correct execution of frames to be mounted. If renovations (the replacement of old wooden windows or obsolete PVC or aluminum) have to be made, we recommend that the new PVC, aluminum or aluminum-timber windows are mounted to fit the old place, as close as possible to the exterior masonry leftover. If you choose PVC, aluminum or aluminum-timber windows, they will be placed in the middle of the wall thickness close to its thermal insulation layer. Any movement of the PVC, aluminum or aluminum-timber windows in the indicated area may affect the quality of installation, favoring partial condensation on windows or in areas immediately adjoining them.
-----------------------------------------------------------------------------------------------------------------------
PVC, aluminum-timber or aluminum frames shall be transported with the glass already mounted, thus reducing the risk of shattering, and also increasing the efficiency and quality of installation.
The sash of the PVC, aluminum or alu-wood windows with low emissivity glass is good to be covered by the masonry over a distance covered in the range of 5-20 mm, on each side. The space between the window's sash and the masonry hole must be at least 10 mm (needed for rode frame in the masonry hole) and no more than 50 mm (higher distances could endanger the stability of the anchorages frame into the wall). This hole will be filled with expanded polyurethane foam, for thermal insulation, and air sealing both outside and inside. After that you must ensure that the windows are perfectly vertical. Check this with a masonry level.
You can also check the assembly without appropriate gear. After mounting, the window, no matter the material, PVC, aluminum or aluminum-wood, open to different degrees from its frame, must remain in the last position, without the trend to close or open permanently.
After finishing the mounting, check again the functionality of the windows or doors. It is possible that immediately after installation small irregularities in the windows' functionality may appear. These must be reported immediately to the company that mounted the PVC joinery, for repairing. Any unauthorized intervention on the joinery can lead to the loss of guarantee. After resolving any such adjustments, considering normal operating parameters, a window must work during installation guarantee time without any major interventions. Small interventions may only be needed for greasing the iron work or for fine tuning the window because of the yearly summer-winter cycle.
After finishing the installation, the company is obliged to grant a guarantee certificate.
