It is not surprising that casement windows remain a popular choice of window style for many homeowners. Apart from their classic look, they have unique features that allow your home to receive natural light, ventilation and a beautiful view of your outdoors. But, like any other style, these windows suffer from problems. This article shares some of them along with ways to address these issues.

Sticking Problems

These windows are designed to open and close without a hitch. There will, however, come a time when one of the sashes becomes difficult to operate. Lack of maintenance can cause rust to form on the hinges. You can fix this problem with an anti-rust spray. Be sure to check your windows’ guide for any mention of recommended brand names or products. Hardware replacement is the next best solution if the spray doesn’t solve the problem.

The frames and the material in them can also cause the windows to stick. Outdoor conditions are one of the reasons why windows get stuck. The sudden changes in temperature can affect wood and vinyl frames, leading to expansion and contraction as well as air leakage or drafts. Pursuing a window replacement is your best bet in this situation.

This new generation of aluminium windows and French windows is aimed at all sectors – individual and shared dwellings and non-residential buildings, suitable both for new-builds and renovations.
A wide variety of applications
Industrial manufacture
Optimisation of cost
Attention to design

Applications
The main characteristics are the speed of production and a capacity to adapt to all the configurations of PVC or aluminium industrial manufacture workshops. All components have been studied very intently to optimise time and production cost: pre-fitted sections, moulded parts for rapid insertion of glass, sections marketed under the NF brand, the possibility of PVC or aluminium interior wood type hinges, multi-station machining matrix so that the desired production rhythms can be followed.

Aesthetics have not been static either: window can be operated with a bracketed handle or embedded lock, with or without a central handle.
