- What ventilation does an insulated conservatory ceiling require?
A PVC-U conservatory with a 2Hot2Cold ceiling requires just an inch gap around the perimeter of the insulation so as to allow breathing space between the bars.
When installing a 2Hot2Cold ceiling on a timber framed conservatory our fitters install air vents into internal ceiling support joists. These air vents allow air to freely circulate between the conservatory roof and 2Hot2Cold’s PVC-U ceiling panels. Airflow is necessary because timber frames allow heat to be absorbed into the ceiling cavity and this can build up into hotspots. Air vents allow this heat to be evenly distributed across the entire ceiling cavity preventing a build-up of heat in one area.
