I have just found out that the new UPVC windows that we have had installed, while extending our house over the last few months, don't have any form of vents in them.
The architects drawings state that the windows should "Provide background ventilation by the use of trickle vents fitted to the head of doors and windows"
I have spoke to the window company, they say they wouldn't recommend fitting the vents as they are noisy when it is windy, but if I really wanted the vents they could retrofit them by taking the open-able windows back to the factory.
So the big question is do I need / should I get these vents installed?
My thinking is if they are not required why do architects & Building Control specify them? but I'm no expert so I would realy appreciate a bit of advice from anyone in the know.
