December 12, 20223 yr We are getting the house boarded this week, and I just had a thought on the insulation of ducts to the exterior. Are this usually lagged with something?
December 12, 20223 yr For our MVHR ducts from outside I used some lengths of Domus Easipipe 2 piece insulation with cable ties.
December 12, 20223 yr Yes they need to be or you can get condensation from them especially when then outside temps are below zero. It only needs to be a thin insulation - I saw it done very successfully with the bubblewrap type stuff with aluminium tape over the joints. Can get it in self adhesive too https://www.toolstation.com/search?q=bubble+insulation
