Window Openers And Mvhr
Posted 14 April 2016 - 03:06 PM
So what I'm wondering is do you guys with MVHR use window openers as much? I'm looking at windows at the moment and wondering if I will use so many openers.

Our heating hasn't been on for several weeks now, in complete contrast to our old house, where the heating is still coming on every day. What's more, I always feel cold in the old house, and warm in the new house.

Peter, I'll keep an eye on what you said cos you're right, the windows have to look even and balanced

If you go for windows which all have a single large glazed unit, you can have some which turn and some which open from the bottom and swing out. They'd all look similar and can simply be left shut if you wish, but I'd think twice about not being able to open them at all.
Fair enough if it's one out of two windows in the same room / area but a sealed room with only the door as the exit wouldn't appeal to me one bit ( with 4 kids ).

Sometimes I want to throw them out the window even when it's non opening....

Non opening are a little cheaper, they also have better U-Values due to the slimmer frames. My large non opening windows have sub 0.7 U-Values.
Non opening windows also don't have any hinges and openers to break and are easier to paint.
They are also more secure.
I hardly ever open a window currently and most rooms in the new place will have french doors so I don't need to be able to open windows. The architect wants some openers downstairs for cross ventilation, I am trying to eliminate as many as possible.
As mentioned if windows are next to each other you do have to be careful as the frames likely will be a different width and you will need escape windows in bedrooms.
Your decision may be influenced by how much solar gain different rooms are likely to have and whether they may need more ventilation due to overheating. Perhaps someone with MVHR can tell us how well the summer bypass works to cool things down compared to opening a window.

Whilst there is a small reduction in price and slightly better level of performance for the non openers, the main reason for installing non openers is that they do not have the ongoing maintenance issues (hinges, seals etc) which given the wind and salt air up here, mean a little more attention and more frequent adjustment would be required compared to more sheltered parts of the country. Why introduce a possible air leakage path when you don't have to?
