This weather is glorious but it does make it hard to sleep. The concrete roof tiles hold heat really well and the whole loft gets and stays boiling hot. When there's a wind it's OK as the eave vents give a decent flow of air but on still nights it's like having a radiator in the ceiling.
I've already got the loft hatch open which makes a big difference.
I was thinking of adding an extractor fan high in the end walls in the attic to try and get rid of the hottest air. Do you think that'd work?
I think it would work. We've got a velux in ours and with that and the hatch open it's cooler up there than the rest of the house at the moment. It's normally hotter up there
Thanks - Velux would be my preference but I don't have the cash at the moment!
Be sure to have a place for the ‘cold’ air to get in too. No point having the fan struggling harder than it has to. I fit inline fans where I can. Easier to fit, easier to access and you can put a larger one in for much less effort usually.
The loft hatch will let in more air than a fan can extract I would think. There are also eave vents all along the roof.
You can get little plastic doo-dahs that hold the felt open under the tiles, British Gas fitted a few in our loft when it was insulated.
If your ceilings are noticeably hot thats a good sign that you need to add more insulation, in winter your loft floor probably feels like a radiator 🙂 Insulation works both ways so will prevent an overheated loft from warming up the house.
Thanks spooky - I looked at those but they also need a breeze to work.
The loft's pretty well insulated - there's noticeably more frost on our roof in winter than our neighbours. Adding more would mean lifting the loft floor to add lower U insulation than the plastic roll insulation already there or adding Kingspan over the top of the floor.
I fitted a ceiling fan in our bedroom. Doesn’t win any prizes for style but it makes hardly any noise & if you open the window & whop the speed I half an hour before bed, it makes it more bearable.
Having a cold/cool shower before bed works, as does a flask of cold water by the bed.
40C at head height in the attic, 32C upstairs, 27C downstairs. As much hot air in the loft as a Friday at Chequers!
Fit an inline fan on the floor of the attic, with a flexible pipe to outside and a double flexible pipe, one through the ceiling to the landing and one from the attic, fit a hit and miss vent on the ceiling one, if you dont want to extract warm air during the colder months, but using the fan in winter will reduce condensation .
