Attic - draught

GBX · 18-01-2024 1:57pm #1

We're in a newish build (2018). There is a draught coming through some of the openings connecting the solar panels into the attic. I'm looking to close them up. What would be recommended material to use?

Hi! A draft through the rafter mounts where they passed through the felt, or how do you mean? Can you see the holes or how do you know?

Presume this is a cold space attic? It's meant to have draughts. As long as its not leaks I.e water.

If its a warm attic then that's different

No leaks. Is it rules/regulation that require the draughts?

I might just pop new seal around the ladder door.

Yep the rafters etc need airflow to prevent condensation and rotting anyway so if this is a normal cold space attic then so long as no leaks and the gaps are small then it will do no harm as insulated attics tend to have vents to actually help. Extra seals on attic door a good idea.

I was going to add that if you have gaping holes in the felt that are left open, it can allow debris and insects in and could potentially let wind-driven rain-water in also. Often it's not a problem as the solar mounts should be on the rafters where the felt is at it's highest point horizontally, hence my question about the holes.
