Insulation

Loft insulation

Anonymous user 28 February 2024 - 4.06 PM

Hi, We have had a new roof and new bathroom, but in the corner of the bathroom the ceiling and top corner of the wall is always full of condensation, I have checked up in the loft and there is no insulation above that section, I have put some insulation above that section now, My question is do I push the insulation right into the corner and fold it down into the eaves or do I pull it back a couple of inch? I’ve read so much on line but have no idea, I’ve read saying it needs to be pushed down onto the wall plate and then some saying pull it back, The corner of the loft is difficult to get to so I’ve put as much insulation above that section of the bath room as I can without touching the breathable membrane

Are you a tradesperson and able to answer this question?

Yes putting some insulation over that spot may help. You don’t want to put your insulation right up into your eaves though, as generally there will be vents in your eaves for airflow in the loft space. Blocking those vents could cause issues further down the line. Putting it just up to the wall plate, not on top of should be fine.

It's really depends. If you have vented soffit you shouldn't push insolation right thing but if your roof/attic it's vented through over fascia ventilation you can push insolation to the end. The idea it's not to block air vents for attic. Hope that's help.

Providing you keep a 50mm space between your insulation and the membrane you should maintain enough air flow. Ideally it is best to cover the wall plate to reduce cold bridging.
