UPVC (Unplastized Polivinyl Chloride)

uPVC (unplasticized Polyvinyl Chloride) frames have the same form & function as conservative frames. The difference is the main material that uses Polyvinyl Chloride strengthen with the unplasticized process, therefore the final material is stronger than PVC. uPVC material reinforce by steel to make the material stronger.

Besides, uPVC has more benefit in term of temperature change endurance, uPVC will not be affected by form transformation during the temperature change, both in cold (-30⁰C) or hot (70⁰C). Different from wood & aluminium frame which easily affected with temperature change, for example when in humid temperature wood tend to expand and in hot temperature wood tend to shrink, it will make the door is hard to be opened.

uPVC is also suitable for buildings in beach areas because doesn’t rusty easily.  The looks of the uPVC frame are neater and no gap between joints because it uses a welding process when assembling.

Compare to the wood frame which finishing eventually faded because of sea breeze and saltwater which impacted to rustiness.

Wahana Tirta Nirmala as CONCH main distributor proudly presents uPVC products as materials with high durability as your main investment in your constructions.
