Technical Guide – Characteristics of PVC-U/UPVC

Excellent weatherability
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 more applicable.

Self extinguishing
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 with dirt…

Thermal insulator
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°.

Acoustic insulator
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.

Weldable
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.

Bondable
Additional plastic components, such as end cap can easily be bonded to PVC-U.
