Even smallest amount of water can cause tremendous damage to flooring, wall and furniture etc., LG UPVC window does not fail of water breakage throughout joint parts where most of aluminum window faces due to high-standardized fusion welding and specially designed stair type structure.
There is close correlation between wind load and safety, because most of the claims and defects root in breakage of windows by using of low quality window. Therefore, while choosing window manufacture, it is strongly recommend to verify the supplier's technical capability, history and reputation to secure the safety.
Smooth Opening and Closing
Coefficient of friction between roller and track rails are the key factor to operate how much smoothly user can slide. Therefore, window manufacture should have the full capability of hardware and accessories development not only as well as profile. Moreover; PVC solid track rail gives another remarkable benefit because the PVC material has unique features of self-lubricating.
Majority of sound insulation property depends upon glass thickness and type, however the importance of material cannot be passed over. Thus drawing capability and fabrication quality in fusion welding parts should be well considered.
While gauging the certain amount of airthrough a unit area in a unit hour, superiority of air tightness is able to be measured.
LG uPVC window has a superior air tightness property owing to a low coefficient of permeability comparing to other materials.
Anti-Chemical property (Anti-weather ability)
Special additives were added to prevent aging or discoloration so that the product may be safely used for a longer period of time. In particular, LG's products are highly resistant to ocean wind containing salinity of ozone, coal gas, acid or alkali.
The PVC material itself is poor conductors of heat of cold comparing to ordinary metal window (1/1,250)
Thus PVC window will increase thermal efficiency so that cuts the electric bills dramatically. This is why we call it as "Energy saving eco-friendly products.
