^What is the glazed window?
How to choose the
Glass has established its reputation as material for filling the light holes because of its transparency,
excellent resistance to atmospheric conditions and pollutions.
Glazing takes about 90 % from the window surface and therefore,
its choice defines the quality of the window such as heat transition and light permeability.
main criteria for right choice are:
- Purpose of the premises - bedrooms, living
rooms, offices etc.;
- Exposure - East, West, North, South;
- Noise - proximity to streets, stations etc.;
- Presence of shadow elements;
- Danger related to burglary.
When glazing places with many visitors,
one of the safety glasses should be used - hardened glass or triplex.
Hardened glass has 4-5 times higher robustness against bent than the usual.
When braked, it divides into very small pieces which can't hurt anybody.
Triplex does not disintegrate in case of braking.
Its advantage is that it protects you against undesired entry and improves the
Which are the
constructive window elements?
- Profile case;
- Profile wing;
- Movable divisor;
- Decorative frame bars;
- Water protector.
What is "mullion profile"?
Both of the fields can be opened and
during opening there is a vertical divisor in the middle. This divisor is called immovable.
the function of drainages?
PVC profiles don't have the necessary static strength as the aluminium profiles. That's why in one of chambers is put metal reinforced profile with different configuration (closed profile "box", "П"-shaped, "L"-shaped as well as
modifications) but they must be zinc coated.
Reinforced profile is joined by self-drilled screws to the PVC profiles in distance of 300-350
mm for the white and 200-250 mm
for the coloured profiles.
What is the glazed
Glazed window is improved modern option of
quality can be estimated based on its heat isolation, noise insulation and sun
light protection. A glazed window consists of two or more glasses separated by
aluminium, plastic or steel spacer (usually perforated). The glasses are agglutinated
to the spacer by butyl rubber and the system is sealed hermetically with
special material - butyl rubber (hotmelt), silicon, polysulfide or
polyurethane. There is a dryer in the spacer which ensures that the air in the
space will be dry.
of the dry air with gas (most often argon) leads to improvement of heat
isolation. Good manufactured glazed window can "live" up to 10 years which is its exploitation period.
Sealed hermetically windows with silicon are not filled in with gas because the
argon can pass through the silicon.
protect ourselves from the sun and overheating in the premises?
How to ensure less heat loss during the winter?
How to achieve good noise
Noise insulation becomes better if:
- The window is made of glasses
with different thickness,
for example 4+5 mm;
- Thicker glasses
5 and 6 mm;
- One of the glasses
is replaced by triplex
- Increasing the distance between the
- stations, airports etc. are used glasses laminated with special noise absorbing resins.
protect our home and office from burglary and entry through the window?
Laminated glass is safe and doesn't
disintegrate in case of breaking. It consists of two glasses agglutinated by special resin which keeps the broken pieces into a whole
and does not allow passing (similar to the front car glasses). Replacing the usual glass by laminated protects your home or office and at the same time achieves better noise
PVC and aluminium joinery with glazed glass ensure better hermetization than the double glazing.
If the external walls have worse insulation than the joinery, especially in panel buildings, the moisture will condense on them. Joinery is part from the
whole heat isolation in the premises. Correct and often ventilation is most important
for avoiding condensation and mould.
When ordering, choose a construction which allows access to each point
of the frame and glass in order to ensure efficient cleaning. If you prefer
window which is not accessible and can't be opened before window that can be
opened, in order to save money, that could be future loss because of shorter
life of the window due to bad maintenance.
The glass must be washed at least once per year in order to be avoided
decrease in the transparency due to chemical reactions on the surface.
The so-called self-washable glasses exist - they have an active coating on the surface which helps for transformation of the dirt and its natural washing by the rain.
