^Flexible spacer by the U.S. company TruSeal Technologies Inc.
During the last 15 years there
is a tendency for repositioning of leading glazed windows producers from
traditional multi-operational technology for pressurization of the glazed glass
to single operational technology using flexible spacer. That technology ensures
very good energy saving indicators and higher production efficiency.
Developed by the American company TruSeal Technologies Inc. more than 25 years ago the pressurization system has first appeared in North America and still has solid positions on the world joinery production market.
The "hot end" system has many advantages compared to the traditional multi-operational technology for production of glazed windows:
- second pressurization is not necessary;
- production of windows with different shapes and sizes without using additional equipment;
- low energy and labour costs;
- big production premises and warehouses are not necessary;
- high heating and
- increased life of thewindow
(about 30 years).
The use of flexible
pressurizing system in the windows production simplifies considerably the
production process and does not require high costs, warehouses, production
premises and many employees. Pressurization
of the window is done only by one operation. Therefore, the technology can
be used in small warehouses with production capacity 20-30 windows per day as
well as in higher volumes production with production capacity 1500-2000 windows
Production line using horizontal roll press and hand application of the spacer allows production of windows with random
shape without loosing time.
extremely simplified process,
lack of waste, environmental friendly production and practically unrestricted
opportunities for the production of special constructions make the TruSeal technology along with the use of flexible spacers, attractive and
desired by the producers.
Windows using flexible
spacers, often called "hot end system", are widely used in
industrial, public and residential construction, incl. for energy saving,
triplex, reflective and decorative glasses as well as in transport and fridges.
