I'm building an extension and need a door and a window. I have planned them to be standard "off the shelf" sizes with a door height of 2100mm and a window height of 1050mm so they fit to the brick courses.
I've looked at B&Q and found the perfect size door and window except the height is 50mm too short. The window height is 970mm, plus the 30mm cill makes 1000mm. They sell an overhead ventilator that will add 44mm. Is this a standard extra you need for these windows to make them fit between standard courses of bricks?
Many Thanks
Mike
