Technical Guide – Characteristics of PVC-U/UPVC
Weather has no effect on PVC-U building materials. Problems
like rotting, rust, etc. just don't apply. Even in special
conditions like coast areas (salt, storm, sun,) PVC-U is
PVC-U burns when subjected to flame, but does not burn by
itself: The product extinguishes immediately when the external
flame source is removed.
Resistance to most chemical products
The list of chemical products that PVC-U is able to resist
is very long indeed and can be obtained on request.
Anti fungi properties
No bacteriological development on PVC-U => hospitals,
food industry, …
Easy to clean = low maintenance
Its closed, smooth surface means that PVC-U is extremely
easy to clean using a gentle household detergent dissolved
in water. This also means that the product is virtually
dirt resistant because there are no pores that can be filled
Like wood, PVC-U is a good insulator. Its coefficient of
heat conductivity is actually slightly lower than wood at
0.17 W/mC°, compared with 0.23 W/mC°. The equivalent
coefficient for aluminium is approximately 210 W/mC°.
The PVC-U window system and the performing seals are developed
in this way that the sound source is shielded from the room.
Easy to work with
Practically any automated or manual processing is possible.
Its ability to be welded means that this material offers
window manufacturers the opportunity to install high productivity
automated manufacturing systems with no need to cope with
materials. A whole window can be welded together in just
a few minutes. The fusion temperature of the weld is approximately
260°C. The sawn joints are heated locally to this temperature.
Additional plastic components, such as end cap can easily
be bonded to PVC-U.
