PVC vs U-PVC
Typically, vinyl windows are made out of a compound known as
polyvinyl chloride, or PVC. In general, PVC can be difficult to push through
the dies, in order to make the extrusion. To aid the PVC through the dies,
plasticizers are added to make the compound more pliable. While plasticizers
aid in the production of the extrusion, they can have some adverse side effects
as well. Plasticizers can make the vinyl itself very dense and brittle, thus
making the final product susceptible to cracking and the effects of
ultra-violet light. This is not exactly the type of product most people would
want in their home.
However, there is an alternative: Unplasticized-polyvinyl
chloride, or U-PVC. With this compound, no plasticizers are added. Instead,
other additives are mixed with the compound to provide protection from
weathering, impact strength, and aid in the processing of the material. The
final product is stronger, longer lasting, and will fight the effects of
Ultra-Violet light.
The "Intus Eforte" Passive House U-PVC window and
door systems offer great performance, quality and price.
