March 5, 20251 yr I have plans to renovate a house, which has the cheap aluminium windows and doors, so I will replace them with uPvc. All companies I have contacted so far use Conch profiles, which seems to be an Indonesian company producing in China. I never heard of them before, but Google tells me they are reliable. Anyone experience with Conch? My first thought was the regular white profiles, but lately I see many houses with the black color profiles, and they stand out from those with white color windows. One of the companies I contacted actually advised against black, as they said they would twist in the hot sun, regardless of that they are reinforced with steel. I have a hard time believing that, and think they may have another reason for their claims. So has anyone experience with black color uPvc windows and doors?
