Insulating at soffit

BarraOG

Hi,

I have mould growing in some of our rooms where the external walls meet the ceiling. I wish to better insulate in our attic near the soffits while maintaining air circulation. How should I insulate the areas without insulation shown in the attached pictures and do I need anything more than just fibreglass? Is it possible to attach an extension to the vents to bring them up above the insulation? If so would this be a good option?

Thanks for your help,
Barry

Hi Barry.

First your insulation roll should be right out to the external block . I can see the internal block the cavity and the external block. You need to push it out further. That's easily achievable here from your pics without blocking the ventilation beyond it.


You can however get what is called a ventilation baffle which are plastic and can be trimmed to size to fit between the rafters and you would push insulation up to it . It directs the air up over your insulation.

Available from various building providers.
