23. System Design - Tilt and turn Windows
1. Glazing seal and casement seal vanish optically as much as possible due to slim design. Only
one type of gasket is used for glazing and internal and external sealing. This gasket is high
efficient in view of air permeability and tightness wind driven rain.
2. Glazing rebate and glazing beads allow the use of glass thickness from 4-6mm single glazing
18-22mm double glazing.
3. The rebate up stand of sash profile outer frame profile has exactly the same design. The
result of equal design are conditions for the end milling of transom and mullions in outer
frames and sash frame.
4. The smooth and beveled bottom of the rebate allows perfect drainage and easy cleaning.
5. The single leg glazing bead is clipped in the glazing bead groove in full length.
6. The reinforcement steel for sash frames and outer frames are identical.
7. The axis dimension of hardware groove is 13mm. this increases the safety of burglar proof
hardware.
24. 8. The higher edge of the rebate works as a guiding edge for striker plates and is stooping the
water from entering side of the window
9. Load bearing parts of the hardware are screw – fixed into two walls of PVC, specially
designed screw channel or thicker parts of profile walls. If it in necessary, additional screw
fixing in steel reinforcement is possible.
10. The outer drainage slots can be made directly through the outer surface of the profile to the
outside or downwards to the outer windows sill.
11. Supplementary profiles are easily fitted with a clip-on system, which takes into
consideration all possible situation on site. Das Fenster offers a full range of Supplementary
profiles, which can be clip-in easily or if necessary, also can be corner welded together with
the outer frame.

32. uPVC profiles are absolutly recyclable. It can be used over and over
again thereby minimizing the harsh effect on the enviroment. It has no
adverse effect on the rainforests and most probably would be the best
alternative to using wood or metal windows and doors.
Typicaly uPVC profiles are lead stabilized, however lead is poisonous
and caused environmental damages. Thus, we are using CALCIUM/ZINC
stabilizer system which replaced lead and make our uPVC product
completely lead-free.

38. Windows and Glazing
This product category applies to PVRS credit RE-R1 Minimum Energy Performance and can
assist for the optional credit RE-2 Cool Building Strategies to achieve a higher Pearl rating.
RE-R1 Requirements
RE-R1 Minimum Energy Performance of the PVRS requires that fenestration is to have a
maximum Solar Heat Gain Coefficient (SHGC) of 0.4 and an area weighted average U-value that
is equal to or less than 2.2 W/m2K. If you cannot provide the "whole system" fenestration U-
value i.e. glass and frame, a glazing center pane U-value of 1.8 W/m2K combined with a
thermally broken frame is currently accepted as provided in the EVPD.
RE-2 Requirements
To achieve a higher Pearl rating, RE-2 Cool Building Strategies may be pursued, which requires a
minimum area weighted average U-value that is less or equal to 1.9 W/m2K and a maximum
SHGC of 0.3. If you cannot provide the "whole system" fenestration U-value i.e. glass and
frame, a glazing center pane U-value of 1.5 W/m2K combined with a thermally broken frame is
currently accepted.

41. Increasing energy, prices and growing environmental consciousness lead to the
expectation that the trend of using UPVC windows and doors will continue worldwide
on a long term basis. On this premise, a greater number of people now are considering
the use of UPVC windows and doors for their requirements. Listed hereunder are
some of the distinct advantages of its use and its performance in comparison with its
metal counterpart.
Energy Saving
As compared to a single glazed metal window without thermal break, the following
shows the improvement of the u-Value:
o UPVC window, single glazed – 22%
o UPVC window, with 24mm double glazing – 55%
o UPVC window, with special thermal insulation double glazing – 76 %
For the total window surface of a building, the savings of energy are in the same
percentage as in the improvement of the U-values as mentioned above. By
improving the type of glazing being used, not only do we get these improvements
in the energy savings but also minimize the use of air-conditioning units thereby
offering more economical benefits.
Thermal and Noise insulation
UPVC frames have high thermal and acoustic insulation performance which can
further be enhanced by the use of special sealed glass units.
Air Permeability and Water Tightness
The glazing seal and casement seal vanish optically as much as possible due to the
slim design. Only one type of gasket is used for glazing and internal and external
sealing. This gasket is highly efficient in view of air permeability and tightness
against wind driven rain. Due to the welding of the corner joints.
These twin counterbalanced gaskets, this UPVC windows can withstand pressures
greater than 600 Pa for a minimum of 5 minutes which can be referred to as the
maximum test pressure.
Durability
UPVC is made up of organic compound that is why it can be considered as a rot proof
material. It does not corrode unlike metal windows and would not definitely absorb
moisture. It has strong resistance to warping, twisting or splitting which is particularly
evident at extreme temperatures like the UAE. ‘Impact modified’ UPVC is treated
with special additives making it extremely tough and durable through years of use.
42. Cost Competitive
The worldwide trend towards UPVC windows and doors is based on the certainty that,
with the right formulation, UPVC profiles will – apart from being low cost to produce
and to fabricate almost effortlessly – provide years of maintenance-free service. And
by saving energy, it contributes to protecting the environment. Recycled PVC frames
can also be retextured into new profiles; this is already proven and done in Europe
particularly in Germany today.
Comprehensive Designs
The possibilities of designs are almost boundless. Suitable designs can be tailor-made
to satisfy every architect or individual requirements. It provides total flexibility,
offering a complete choice of styles, shapes and sizes. The visual appearance is
elegant, simple and keeping with the latest architectural requirements.
Environment-friendly
UPVC profiles are absolutely recyclable. It can be used over and over again thereby
minimizing the harsh effect on the environment. It has no adverse effect on the
rainforests and most probably would be the best alternative to using wood or metal
windows and doors Typically UPVC Profiles are lead
Stabilized, however lead is poisonous and caused environmental damages. Thus, we
are using CALCIUM/ZINC stabilizer system which replaced lead and make our
UPVC product completely lead-free.

57. Summary of PVC Combustion Properties
IGNIBILITY
Very difficult to ignite with common ignition sources
COMBUSTION RESISTANCE
PVC-frames will only burn when subjected to an external heat source.
Once the source is removed, the flames will self-extinguish
HEAT RELEASE
Heat release and total heat of combustion significantly lower than
those of other thermoplastics
SPREAD OF FLAME
Limited spread of flame characteristics – high classification in UK
national building fire test.
RESISTANCE TO SUSTAINED COMBUSTION
Burning PVC forms a protective layer or char on the surface and
insulates the material. The oxygen, which is needed for combustion, is
excluded.
58. TOTAL HEAT RELEASE FROM DIFFERENT MATERIALS
Thickness: Evaluation at typical end-use thickness
Irradiance: 25kw/m₂
Materials Thickness Total heat release
(M.J/m at 10mins.)
Pine 25 91
Hardboard 6 62
Chipboard 12.5 57
Oak 25 45
ABS 3 27
Flexible uPVC 2.25 23
uPVC 3 17
Spread of flame
- Many uPVC formula exhibit flame spread in laboratory tests.
- In national building tests, many uPVC formulas qualify for the best
possible classification for combustible building materials.
59. Classification achieved:
Country Test Method Classification
UK BS 476, part 7
BS 476, part 6
France NF p 92-501
Germany DIN 4102, Part 1
USA ASTM E 84
Notes:
(a) Class 1 can only be achieved with uPVC when reinforced or lifted to a non-combustible backing.
(b) Class 0 is achieved by appropriate performance in both part 6 and part 7 of BS 476.
