Evolution of sub-floor moisture management requirements in UK, USA and New Zealand 1600s to 1969

Nigel Isaacs

The purpose of this paper is to review the historic development of the requirements for sub-floor (also known as “basementless space” or “crawl space”) moisture management in the…

Void conditions and potential for mould growth in insulated and uninsulated suspended timber ground floors

Sofie Pelsmakers, Evy Vereecken, Miimu Airaksinen, Cliff C.A. Elwell

Millions of properties have suspended timber ground floors globally, with around ten million in the UK alone. However, it is unknown what the floor void conditions are, nor the…

Design limits for framed wall assemblies dependent on material choices for sheathing membranes and exterior insulation

Ivan Lee, Patrick Roppel, Mark Lawton, Prudence Ferreira

The purpose of this paper is to propose a methodology for evaluating the hygrothermal performance of framed wall assemblies based on design limits. This methodology allows…

Characterisation of air permeability of common ceiling linings and penetrations

Stephan Harald Rupp, Manfred Plagmann

Air permeability of ceiling linings is an important element in understanding air and moisture flux from living spaces into the roof cavity. Ideally, these two spaces are decoupled…

Must attic ventilation be preserved in energy retrofits?

William Rose

The addition of thermal insulation into attics along with air-tightening of the ceiling plane is a common first step in making homes more energy efficient. Attic ventilation was…

Hygrothermal simulation of cathedral ceiling roofs with ventilated roofing tiles

Philipp Kölsch

The surface temperature of the sub-roof beneath the ventilation layer and the tiles is one of the most important factors for the hygrothermal performance of pitched roofs. The air…
