UPVC, also known as unplasticized polyvinyl chloride, is a low-maintenance building material used as a replacement for painted wood, primarily for window frames and window sills when installing double glazing in new buildings, or as a replacement for old single glazing windows in schools and classrooms. It has many other uses, such as screens and weather panels. The same material has almost completely replaced the use of cast iron for plumbing and drainage, and is used in drainpipes, gutters and downspouts. These products are often collectively referred to in the home improvement industry as "rooflines". Modern steel windows offer the same high level of aesthetics as those produced in the past and are available as similar replicas but with many significant benefits. As a result, these windows have been successfully installed in thousands of homes that have appreciated in value because they have been lovingly restored.
Climate performance
Long experience has shown that steel windows are suitable for most locations and exposure conditions.
Security
The inherent strength of steel windows guarantees maximum rigidity once the window frames are installed and glazed. The most secure steel window is an ordinary standard window divided into small panes of glass, with vertical and horizontal bars riveted with dowels on each side, the frame and with strong cross joints. Even if the glass is broken, you won't be able to get in through this window. A high level of security can be achieved with large steel windows opened by various locking methods, while an additional fan is mounted inside the upper glazing niche ensures permanent or controlled ventilation when the window lock is closed.
Operation and Control
Available steel window hardware offers a wide range of sash handles and supports, flap openers, hinges, pivots, latches and latches, all designed to provide the performance and security of optimal flexibility. Strict quality control procedures combined with modern manufacturing techniques ensure that all products are of a consistently high standard.
Installation
Steel windows are suitable for direct attachment to masonry, concrete, stone or substructures.Glazing:Steel windows can be simply glazed or equipped with insulating glass units.
After-care and maintenance
The modern steel window is an extremely durable and high-performance product. This performance can be improved by following good housekeeping. Frames should be cleaned periodically with a mild, non-alkaline detergent in warm water and a soft cloth or sponge.
Glasses and perimeter seals should be inspected annually, and appropriate maintenance should be taken. Galvanized steel windows that are not factory finished with a polyester powder coat finish are manufactured with spacing adjusted to allow for up to three or four coats of paint on contact surfaces. If the repair schedule has exceeded this value, remove paint from all mating surfaces before repainting.
