Name |
: |
SynerJy; 3mm
system for windows and doors. |
|
Grade Reference |
: |
SYN10 White 01. |
|
Material |
: |
Acrylic
modified high quality impact resistant, white unplasticised
Polyvinyl Chloride extrusion to produce a rigid multichamber
extrusion. |
|
Physical
Properties |
: |
Comply with BS
EN 12608 Annex A. |
|
Colours |
: |
White,
Mahogany, Light Oak and Cherry |
|
Appearance |
: |
Smooth, white,
non-porous gloss surface, complies with requirements of BS
EN 12608 5.2. |
|
Surface Finish |
: |
Stabilised
against UV light to prevent excessive colour shift. |
|
Corner Welding |
: |
Homogeneously
welded. Weld not to fracture below 25N/mm² BS EN
12608, test method EN 514. |
|
Window System |
: |
Subject to
manufacture in accordance with the Synseal Technical Manual
recommendations, the casement window system will conform to
the requirements of the standard BS 7412.
In addition, a
GGF standard window manufactured from SynerJy profiles, in
accordance with the Synseal Technical manual, using low-e
glass in the unit, achieves a U-value of 1.9 wm-2K-1
when hot-box tested by the British Board of Agrément. |

Physical
properties of PVC-U Type A Material Grade Ref.: SYN10 White
01 |
|
Sound
Installation |
: |
30 dB minimum. |
|
Thermal
Conductivity at 20 deg C |
: |
Typical test
value 0.16 W/M deg C. PVC-U has a low thermal
conductivity, and is virtually constant over a wide
temperature range. |
|
Fire
Classification/ Performance |
: |
PVC-U is a
difficult material to burn which decreases the likelihood
and development of fire "When exposed to a flame, PVC-U
carbonises without burning or producing droplets, and it has
been established that Syneal profiles can be used to achieve
a Class 1 surface spread of flame rating to BS 476 : Part
7". |
|
Heat Reversion |
: |
To BS EN 12608
clause 5.5 (Test method: 1 Hr at 100 deg C). When
tested in accordance with EN 479, the mean maximum reversion
value for individual samples shall not be greater than 2%
for profiles and 3% for glazing beads. |
|
Heat Ageing |
: |
To BS EN 12608
clause 5.6 (Test method 1kg from 1.5m at -10 deg C).
When mainframe, casement and sash profiles are tested in
accordance with EN477, no more than 1 sample shall exhibit
cracking through the entire wall thickness of the profiles
on either face. |
|
Heat
Resistance/Softening Point |
: |
To BS EN 12608.
When tested to BS EN ISO 306 (Method B) Minimum Vicat
softening point: 75 deg C. Typical result 82 deg C.
This is well
above the requirements of the UK and German specifications. |
|
Flexural
Modulus of Elasticity |
: |
To BS EN 12608.
Minimum requirement 2200 N/mm² value, when tested to EN ISO
178. Typical result 2350mpa. |
|
Co Efficient of
Thermal Expansion |
: |
Allowances for
changes in dimensions are required that occur when the
temperature varies. The co-efficient of linear
expansion for PVC-U is 6 x 10-5
per ºC. It is about half that of many other
thermoplastics. |
|
Profile
Properties |
: |
Clause 5 of BS
EN 12608:2003. |
|
Retention of
Impact Strength after Artificial Weathering |
: |
To BS EN 12608
Maximum 40% reduction of original value specified when
tested to EN513. |
|
Colour Fastness |
: |
Change in
colour after exposure in accordance with EN 513 expressed in
ΔE* not greater than 5 and Δb* not greater than 3. |
|
Bulk Density of
Powder Blend |
: |
Typical test
value 0.63 - 0.64.
Minimum
requirement : Non specified. |
