Factsheets
Upstands below the main window
This fact sheet explains the construction of the new window upstands.
Tilt only window openings where the windowsill remains at its current height
Following resident feedback, we can now offer a choice of opening mechanisms for the kitchen, side lounge and bathroom windows. The available options ensure that the room ventilation will be comparably better or similar to your current windows. During your home visit, you will be able to make your choice of these windows, alongside your radiators and blinds/curtains.
All three mechanisms - electric winder, manual winder, and handle, have slightly different implications on the window opening and associated ventilation as detailed below:
