Hi all
My house has sloped ceilings (skeilings) toward the edges of the rooms with exposed rafter feet on the outside. The ceiling meets the wall at roughly 45 degrees for about the first 75 cm, before levelling off.
Having taken the plasterboard off I see that there is no insulation whatsoever on the loft side of these sloped ceilings, so I am going to install insulation boards between the rafters (100mm rafters so I’ve bought 50mm insulation board - Kingspan), and then I will be installing insulated plasterboard afterward.
My question is -
how do I install the Kingspan; do I cut an edge of the insulation board at 45degrees so it fits flush with the top of the inside side of the wall, or do I just put it in straight as it’s cut?
Thanks
