Garażowe - Doors of the future !
ALUTECH/GUENTHER Garage doors are
good at keeping heat in the premises
providing a comfortable temperature
and saving on heating costs in the
winter. The thermal transmittance coefficient
for ALUTECH /GUENTHER doors is:
• Trend Series (panel 40 mm) —
• Classic Series (panel 45 mm) —
Thermal insulation U = 1.0 W/(m2К) is
comparable with a brick wall of 60 cm
Panels with such a thickness are the
basis of the doors’ durability, robust
construction and resistance to wind and
The tests have showed that the
ALUTECH/GUENTHER Classic Series
doors withstand a wind load of 700 Pa,
that corresponds to wind speed of
ALUTECH/GUENTHER sandwich panels
have a closed loop design where steel
sheets are interfixed into a «lock». Such
a design protects panels against delamination
in the sun and in the case of sudden
closing of doors or similar damage,
prolonging the operation of the door.
Tests in independent laboratories
proved that ALUTECH/GUENTHER door
leafs can withstand exposure to «salt
fog» for 750 hours which corresponds
to 15 years of operation
regions and polluted industrial areas.
These unique anti-corrosion properties
are possible due to:
• thickness of zinc coating (16 micron);
• double layer paint-and-lacquer coating
(PUR-PA) 23-35 micron thick.
ALUTECH/GUENTHER doors are
equipped around the perimeter with
seals from modern polymer materials
that tolerate temperature extremes.
Flexible sealing inserts provide a reliable
seal of the opening.
The design of the roller brackets allows
adjustment of the door leaf position in
relation to the opening, which helps to
avoid gaps and undesirable loss of heat
between the door leaf and garage walls.
Design of ALUTECH/GUENTHER sectional
doors provides protection from:
• finger trapping;
• uncontrolled movement of door leaf;
• door leaf fall in case of spring break.
Conformance to European standards
EN 12604, EN 12453, EN 12424,
EN 12425, EN 12426.
Lifetime of ALUTECH/GUENTHER springs
on sectional doors is up to 25 000
open/close cycles which corresponds
to approximately 17 years of operation
with 4 open/close cycles per day.
Springs capable of 25 000 open/close
cycles are offered as standard at no
ALUTECH/GUENTHER doors are produced
individually for each client at
a standard price, in height and width
increments of 5 mm.
A wide choice of panels and colours
allows clients to select a door to suit any
project. The Alutech Group of Companies
offers 5 types of door leaf and an
extended colour range for their doors –
10 colours with no extra charge.
ALUTECH/GUENTHER not only produces
qualitative doors but also provides quick
and reliable service maintenance. To
ensure quick maintenance from regional
offices the Alutech Group of Companies
has organised and stocks a wide range
of spare parts and other resources in its
The range of ALUTECH/GUENTHER garage doors is presented in two series — Trend and Classic. You can easily choose the correct type of doors to suit the climatic conditions in your area, features of operation, and your budget.
Trend Series doors are economical and functional doors of 40 mm thickness with fittings made of galvanized steel, which are optimally suited for regions with temperate and cold climates. They comply with
European standards; in addition all the safety systems are available at no additional charge. The standard door package includes a spring with a maximum lifetime when compared to competitors – of up to 25,000 open/close cycles. Classic Series doors are safe and practical doors at a reasonable price.
• The thickness of a sandwich panel is 40 mm
• The thermal transmittance coefficient is 1,35 W/(m2К)
• Roller brackets and intermediate hinges are made of galvanised steel
• Can be installed in an opening greater than the ordering size
• Curtain balancing with tension springs or torsion springs
• The maximum size of the garage doors is 6000 × 3000 mm
Classic Series doors are reliable and provide good insulation qualities as the panels are 45 mm thick. Classic Series doors are successfully installed and operated in countries with cold climate: Finland, Norway, Denmark, Sweden and others. Rolling brackets and intermediate hinges are made of stainless steel and have high anti-corrosion properties, which makes it possible to operate the doors in areas with high humidity.
The thickness of a sandwich panel is 45 mm
• The thermal transmittance coefficient is 1,06 W/(m2К)
• Roller brackets and intermediate hinges made of stainless steel
• Door leaf balancing with tension springs or torsion springs
• The maximum size of the garage doors is 6000 x 3000 mm
Angle bars and the cover strip of Classic Series doors may be positioned in the opening so that it allows you to install the standard doors in the opening of a greater size. These design elements are made of hot-galvanised steel, which is further coated with a protective lacquer coating (standard — white colour RAL 9016). At your request, angle bars and the cover strip can be painted in the colour of the door leaf so that it will add to the doors harmonious appearance.
The panel of 45 mm thickness is a pledge towards excellent heat insulation. The thermal transmittance coefficient of ALUTECH/GUENTHER doors is 1,06 W/(m2 К), which is comparable with the thermal insulation of a brick wall of 60 cm thickness. These Doors will allow you to save money annually on heating costs. These claims are confirmed by tests conducted at the Rosenheim GmbH Institute (Germany).
In heavy rainfall water can collect at the bottom of the doors. Our special technical solution minimises the possibility of corrosion in high humidity environments, providing an attractive appearance of doors for a long time.
EPDM sealing inserts of frost-resistant EPDM are located along the door perimeter. The top and side seals have two wings. This improves significantly the air tightness of the structure, and the air chamber between the wings provides the doors with additional heat insulation. Classic Series doors have the best air tightness — the 5th grade of breathability under EN12426
The spring mechanism compensates for the weight of the door leaf, this balancing allows even heavy doors to be easily opened and closed manually. Lifetime of springs is up to 25 000 open/close cycles. This corresponds to 17 years of service with 4 times daily opening/closing during the period.
Flush-mounting of angle bars and the cover strip are provided with Classic Series doors — these elements are installed behind the opening. They do not have direct contact with the street and do not conduct cold in the premises. This design of the angle bar can significantly improve the thermal insulation properties of the doors. Mounting behind the opening provides additional protection for the angle bars from exposure to high humidity.
Torsion springs are equipped with ratchet couplers that block the door leaf from falling in the case of spring breakage. This protection system is supplied at no extra cost and ensures safe operation. ALUTECH/GUENTHER doors comply with European standard EN 13241-1, EN 12604, EN 12453, EN 12424, EN 12425, EN 12426.
Multi-coated sandwich panels and painted side plates provide high resistance to corrosion of the doors. The ALUTECH/GUENTHER door leaf withstands 750 hours of «salt fog», which corresponds to 15 years of operation in a coastal area. This is confirmed by independent tests.
Adjustable rolling brackets allow achieving close proximity of the door leaf to seals. This protects against draughts and retains heat in the premises. The proximity adjustment can be carried out both at the time of installation and in the course of their service. Your doors will be energy efficient for many years.
Intermediate hinges and rolling brackets made of stainless steel have high anticorrosion properties, which guarantee reliable operation of the doors, even in premises with high humidity. Stainless accessories are included in a standard set of Classic Series doors and are supplied at no extra cost.
Thanks to the use of rollers with rolling bearings the doors move smoothly and quietly. Ball bearings of a closed type, protected from dust and moisture are used in ALUTECH/GUENTHER doors. These bearings do not require relubrication and provide high reliability and durability of the running gear.
The large thickness of a sandwich panel is the basis of the strength and stability of the doors to shock and wind loads. The 4th class of wind resistance under EN12424 — doors withstand wind speeds up to 120 km/h, which is confirmed by tests conducted at the Rosenheim GmbH Institute (Germany).
