Q-Windows is using Aluminium Frame while Optima is using uPVC if I'm not mistaken. uPVC have issue with degrading color with UV (sunlight).

QUOTE(Bjorn1688 @ Mar 14 2019, 06:48 PM) Used Q-Windows and their services were excellent and they did what they said it would do. Did Q-Window block all the sharp noise and the humming noise in your case?Build quality exceeded my expectation and after 3 years it still operates as per the day it was installed. I did try to deal with Optima Windows but I guess the SA saw me as not a potential buyer for his products and did not want to entertain me, therefore it was a no deal or quotation.  I having traffic noise on my front road and highway. |
