With insulation along with the roof deck, you don’t want any venting within the roof deck. You may place ventilation channels previously mentioned the topside insulation for those who’d like, but don’t vent below the insulation. It'll reduce your R-value.

The previous staying unvented and latter becoming vented. The latter doesn't do the job if HVAC is up there and a retrofit could in no way deliver ductwork inside w/o highly-priced interior re-get the job done. Lstiburek describes a double-roof design that hybridizes vented and unvented but that wouldn't work for just a retrofit Except you're redoing the whole roof deck and that is tough.

There are also differing kinds of obstacles that can be Component of an insulation solution or bought and set up independently to raise vapor and thermal transfer through a wall assembly.

Additionally, scaled-down air leaks may possibly seem nearly anyplace, from electrical stores and close to plumbing spaces to gentle installations and locations the place pipes happen to be set up.
