WALLS CEILINGS & PARTITIONS

摘要

Along with external walls and linings, internal party walls can act as pathways for heat loss, in which case they will need to be insulated, with careful attention to detail so as to avoid thermal bridging and meet target levels of airtightness. These requirements may also apply to ceiling construction, for example below uninsulated lofts or where soffits are immediately below roof joists. Vapour control layers and breather membranes must also be correctly specified for satisfactory thermal performance, and interfaces with windows, doors and floors should ensure continuity of the thermal envelope. Multi-foil and vacuum insulation will help reduce build-up thickness. Your choice of wall, ceiling, partition, insulation and weathering materials will have direct and indirect impacts on CO_2 and other harmful emissions, so you need to check product certification.
