Insulation for a stick-frame roof — but we want the exposed beam look
so we bought a house that was built in the 50s and we had take out the drop ceiling and old drywall ceiling above that to run new wiring.
Bottom line – wife saw the open ceiling and asked if we could keep it that way and ya’ll know that saying. Anyways – I look at the roof and it is just 1×6 boards laid across the rafters with a shingle roof on top. Roof nails piercing the wood all over.
So I would like to give my wife the look of exposed beams but I am thinking how do I insulate it. The roof is brand new on the outside, so I don’t want to disturb that.
My thought after doing some reading and watching some Utube videos is:
1 – attache a small piece of wood on the roof rafters and then sliding 1.5 inch Poly-ISO roofing insulation in-between the rafters. This will give some air space between the roof and insulation.
2 – then attach T&G on the underside of the small piece of wood to give my wife the look she wants and also another layer of open space for air to flow between the insulation and T&G.
So now my question – (we live in NE Florida and the house faces south):
Will this be enough insulation to keep the rooms warm and cool?
OR should I double up the insulation and apply it directly to the underside of the roof?
Thank you for your time – it is greatly appreciated.
