MULTIPLE GLAZING

Hronas uses companies’ Saint-Gobain and Pilkington float glass for
producing multiple glazing units.

The main criteria determining the choice of the type of multiple glazing
are thermal and sound insulation, light tr

ransmission.

Thermal Insulation

Currently, a single-chamber multiple glazing unit having two transparent
panes and featuring heat transmission of 2,8 W/m2 K is the most popular in
Lithuania. A tendency of choosing multiple glazing units with the heat
transmission of 1,1 W/m2 K for both individual houses and blocks of flats
becomes more and more obvious. The multiple glazing units featuring such
low heat transmission consists of an ordinary pane and a pane having soft
elective coating on it. Multiple glazing units with intermediate thermal
characteristics are also available. These are multiple glazing units
consisting of either two panes, one of which has hard selective coating on
it, or three panes. The heat transmission of these multiple glazing units
is 1,8 W/m2 K.

Sound Insulation

The sound insulation of a single-chamber multiple glazing unit having two
4 mm panes is more than 28 dB, while the sound insulation of a double-
chamber multiple glazing unit having three 4 mm panes exceeds 32 dB.

Light transmission

|Glass type |Light |Light |
| |transmissi|reflecti|
| |on |on |
|Transparent glass|0,89 |0,08 |
|Green tinted |0,78 |0,07 |
|glass | | |
|Brown tinted |0,61 |0,06 |

|Glass with hard |0,84 |0,14 |
|selective coating| | |
|Glass with soft |0,86 |0,10 |
|selective coating| | |

The above values are specified for 4 mm thick glass.

INTERNAL WINDOWSILLS

Internal windowsills can be made of wood, particleboard or all plastic.
Wooden windowsills best match wooden windows. Plastic windowsills are
recommended for rooms with high humidity. It is pa

articleboards, which are
currently the most popular due to their price, appearance and performance.

EXTERNAL WINDOWSILLS
External windowsills made of galvanised steel sheet look habitual in
earlier built houses. External windowsills made of plastic-coated steel
sheet are acquiring growing popularity among those wishing to make their
house look somewhat special. This coating gives windowsills a desired
colour as well as protects them from rusting.

VENTILIATION SYSTEMS

Hronas can offer any desired ventilation system within the range used in
window constructions. Long experience and continual learning from the life
enabled to choose several the most advantageous systems. We regard DUCO
register ventilation systems the most advantageous in terms of price and
quality. Depending on the location and type of premises we can offer
RENSON, SCHÜCO or TITON ventilation systems.

ACCESSORIES

We use SCHÜCO and GRETSCH-UNITAS (GU) accessories for our products. Branded
SCHÜCO accessories have been specially designed to be use for the
manufacture of this window system and that is why we are using them for PVC
and aluminium products. All the locking parts of accessories are made in
metal. The rubbing parts are made in special plastic alloy which is also
used in machine industry, especially for parts subject to wear and tear.
This makes the SCHÜCO accessories almost maintenance-free.

Besides, these accessories are normally completed with burglarproof parts
and belong to the SFI cl

lass of safety. All the SCHÜCO accessories bear
crowns as the company’s trademark.
German GU accessories are used with wooden products and, if wished by a
customer, with PVC products. These accessories are among the best as
regards their constructional properties and variety.

WOODEN PRODUCTS
Wood is one of the oldest building materials used. Influenced by
environmental changes, natural wood may be cracked and deformed.
JSC “HRONAS” uses three-layer pre-glued squared beams of Karelian pine for
production of windows and doors. Blanks certified according to the German
DIN standards are especially hard and deformation resistant. Larch,
mahogany or oak is available at request.
The main production processes (cutting, milling, gluing, priming and
painting) are automated employing new generation machinery and equipment of
German companies Michael Weinig AG, Leitz, Reinhold Hess. End-item quality
control and grinding of primed surfaces are carried out manually.
Such faultless work performance enables to grant a five years’ guarantee
not only for constructions, but as well for painted/varnished surfaces.

FRAMES COLORS
Windows are primed, ground, and painted twice with environment-friendly
acrylic paint manufactured by the German company GLASURIT. This is one of
the best paints currently manufactured in Europe. Products may be painted
in all RAL colour palette colours or coated with colourless paint retaining
wood texture.
Glazing beads are fastened with special tools in such a way, that no traces
of hammering and nail heads are left. This pleasant trifle improves the
aesthetic appearance of the product, especially if products are coated only
with colourless varnish.
Windows are sealed with special-purpose silicones and two not freezing to
the surface, milled in sealing gaskets. These silicon-based gaskets are
extremely resistant to environmental factors (humidity, frost) and
mechanical impact.
New type frame and leaf water boards of the German company GUTMANN are
fitted for rain water drainage. Their distinctive feature is that they
cover the whole profile instead of a part of it. Water boards are not
fastened with nails or screws, but hung on specially milled recesses.
To ensure top quality and aesthetic appearance, we offer to cover wooden
windows all around with aluminium plates. To implement this solution, the
company uses GUTMANN 4000 system. Aluminium plates as well as the above
mentioned water boards are fastened in such a way as to prevent damage of
the protective impregnated wood surface. Wood covered with aluminium is
especially suitable for conservatories – natural wood is seen from inside,
the problems of condensate removal from the roof structure inside and
rainwater drainage outside is successfully solved. The exterior is well
protected from hazardous environmental factors.

ALIUMINIUM PRODUCTS

Aluminium is a light, stable, rust-resistant and maintenance-free material.
To produce aluminium products company Hronas uses section systems of the
world leader SCHÜCO.
According to constructional principles company’s SCHÜCO products are
divided into 29 systems. All the systems have subsystems and can be
combined with one another.
Heat transmission properties of sections:
With cold insulating bridges (using polyamide or polymerise gaskets)
Without cold bridges
Position in facade:
Flat or sloping facades with transoms visible from outdoors
Structural glazing systems
Roof structures
Systems of aluminium cassettes and their fastening elements used for facade
decoration
Surface coating:
Painted sections
Anodised sections
Special constructions:
Fireproof
Ball-proof
Reinforced (special sections and accessories)
All articles of the SCHÜCO systems are completed with the branded SCHÜCO
accessories. Special orders (devices for automatic closing of doors and
windows, solenoid locks etc.) are to be agreed separately based on a
customer’s needs.
It is obvious that staff possessing appropriate skills is needed for all
the aluminium systems to be used correctly as regards construction and
price. The projects carried out by company Hronas allow to give a customer
a guarantee based not on a word of honour but on everyday experience.

UNFRAMED GLASS STRUCTURES PRODUCTS

Employees and customers of various offices, banks, companies have been
enjoying unframed glass structures for many years. Partitions and doors
made of unframed glass structures heartily invite you to enter, or at least
to take a peep at what is going on behind them. Unframed glass structures
are made of two main components:
1. Toughened glass.

[pic]  5-6 times as impact resistant as not toughened glass,

[pic] Stands great temperature fluctuations,

[pic] Safe – when broken, it goes to tiny scraps not presenting any serious
danger to those present,

[pic] Not apt to deformation.
2. Fastening accessories and accessories for opening/closing.

PILKINGTON, SAINT-GOBAIN, EUROGLAS and GLAVERBEL glass is mainly used in
glass structures. Glass may be clear, coloured, enamelled.
The second component of unframed glass structures is fastening accessories
and accessories for opening/closing. This is especially important part of
the structure. Structure reliability and service life will depend on proper
choice of accessories.
