Warm deck flat roof insulation between joists.

Here the roof deck is maintained at the same temperature as the internal conditions hence warm deck roof. Warm flat roofs do not need to be ventilated as the insulation is. If you put insulation under the decking and between the joists you lower the temperature of the decking and lower the due point thus bringing it closer to the danger point of being in the building. The roof itself is therefore kept warm.

A flat roof where the insulation sits below the waterproof membrane and above the structural deck is a warm roof deck. The vapour control layer is above the decking but below the insulation. Cold deck roof a cold deck roof is where the insulation is placed between the joists rafters or in between the ceiling joists in the case of a pitch roof. Set the quinn therm qrfr ply insulation boards onto a wide 30mm bead of vapour resistant sealant applied to the upper surface of all the joists and cross noggins.

A warm roof is defined as being when the all or the majority of the insulation is above the joists or deck.

By majority the rule of thumb is that in a domestic house not flats approximately a third of the total thermal performance of insulation can be placed below the deck with two thirds above.
