Order windows with glass bonded using STV® technology and take full advantage of the possibilities offered by modern insulating glass units. You will facilitate your team's work, reduce the risk of damage, decrease the number of complaints, and your customers will be more satisfied.
A modern insulating glass unit is an incredibly durable and rigid window element that offers much more than just thermal and acoustic insulation. Bonding the glass using STV® technology brings immediate business benefits, such as:
The practical benefits of STV® technology appear at every stage of the investment.
Sashes using bonded glass are more resistant to torsion and deformation. Storing them in sub-optimal conditions is less risky, and maintaining the correct geometry ensures a smooth installation process.
Conditions during wet trades require windows to remain in a tilt position for many weeks. This can cause them to sag and function improperly on the day the project is handed over, creating extra rework for the installation team. STV® reduces the risk of this phenomenon.
Typical complaints reported by users of new windows rarely concern the profiles themselves – they most often relate to the operation of the window. The use of STV® technology improves the efficiency of transferring forces to the hinges, limits window sagging and thus reduces the number of service visits related to hardware adjustment.
Installation teams also appreciate that the elimination of steel reduces the weight of the window.
Thanks to constructions with bonded glass, you also receive two important arguments with which you can convince your potential customers:
When ordering S9000 PVC windows, choose the STV® glass bonding option. That is all that is needed to implement this technology. It does not entail any restrictions, and even replacing a damaged pane is not significantly more complicated than the traditional approach.
On your next order, inform our Sales Department that you want to take advantage of glass bonding, or select the appropriate option yourself in eko4u.
