Condensation in roofs
A review of design principles for minimising the risk of condensation in roofs and consequential damage to decorations or structure. DG180 

Damp-proof courses
Water penetration is the prime cause of deterioration in building structures and materials. The presence of excess moisture encourages the growth of moulds and wood-rotting fungi. This Digest discusses moisture exclusion, selection of materials, and installation of damp-proof courses in walls and chimneys. DG380 

Diagnosing the causes of dampness
This Guide is the first in a series, and deals with the first step to solving any damp-related problem – diagnosing the cause correctly. GR5 

Drying out buildings
Describes methods of drying out new buildings and of testing the condition of walls, floors and joinery. DG163 

Effects of moisture in porous masonry
Reviews the subject of moisture movement in masonry materials. Looks at the theory of wetting, theory of drying, movement of water in materials, computer modelling of water movement, and measurement of moisture movement, and examines moisture-related problems. BR304 

Estimation of thermal and moisture movements and stresses
Considers movements in building materials and components, their sources and design strategies for accommodating them, and the causes of deformation and stress. See also Digest 228. DG227 

Estimation of thermal and moisture movements and stresses
An analysis of thermal and moisture effects including tabulated data for assessing the change of size and shape of materials. See also Digest 227. DG228 

Interstitial condensation and fabric degradation
Discusses the occurrence of interstitial condensation and its possible damaging effects on the structural integrity of buildings. Gives advice on preventative and remedial measures. DG369 

Modelling and controlling interstitial condensation in buildings
This paper considers the models that are available to analyse the risk of interstitial condensation within structures. To run the models, certain properties of materials need to be known. The paper discusses the availability of these properties and the appropriate boundary conditions that should be used, and makes recommendations on which models should be used for a range of different types of structure. This guidance is intended for those involved in the design and construction of buildings. IP2/05 

Modelling condensation and airflows in pitched roofs
The risk of condensation in cold pitched roofs is dominated by airflows from the living areas of a house into the loft and through the loft to the outside. The effect of these airflows is excluded from the current British Standard procedure for assessing interstitial condensation risks. This paper discusses the factors that are necessary to construct a realistic model to predict condensation risk in structures with significant airflows, and describes the sources of the data needed to run such a model and the resulting outputs. IP5/06 

Moisture relations in timber-framed walls
Examines the effects of different types of occupancy on the moisture levels within the external walls of timber-framed houses. IP21/82 

Mould and its control
Information about the nature of mould and the factors which govern its growth. The basis for specifying cleaning and re-decoration procedures is discussed. IP11/85 

Remedying condensation in domestic pitched tiled roofs
One of the most common and cost-effective ways of saving energy in houses is to insulate the roof space, usually by laying insulation between the ceiling joists. But adding insulation increases the risk of condensation in the roof and can lead to damage to the contents of the loft, the insulation and possibly even the roof structure. This Good Repair Guide describes how to find out whether a pitched tiled roof is at risk from condensation and how to minimise it. GR30 

Rising damp in walls
This Digest considers the causes of dampness in walls and offers a positive method for the diagnosis of rising damp. It suggests possible remedial measures that can be taken to avoid rising damp such as providing a complete moisture barrier by insertion of a physical damp-proof course or the non-traditional method of chemical injection. The repair of plaster damaged by damp is also discussed. The Digest is a new edition of Digest 245 DG245 

Surface condensation and mould growth in traditionally-built dwellings
Condensation and mould growth are widespread problems in all housing sectors. This Digest considers the circumstances that lead to surface condensation and mould growth, and suggests ways of reducing their incidence in dwellings of traditional construction. DG297 

Tackling condensation
This guide is the result of BRE monitoring carried out in more than 100 occupied buildings over six winters. It describes the basic principles of condensation and the interacting dynamic environmental conditions which cause it, suitable site investigation methods and available remedies. It also contains case studies which give examples of problems and their solutions. BR174 

Temperature and humidity in batten voids
Changes in construction methods and materials, such as breathable membranes and high peformance thermal insulation, introduce new issues for the integrity of buildings. This Information Paper describes measurements within batten voids to determine the conditions in which condensation occurs; and whether the condensation leads, in turn, to increased levels of moisture in battens. In theory, there could be risks of condensation in batten voids which may affect the moisture content of battens. IP20/01 

Treating condensation in houses
Over 2 million UK homes suffer from widespread condensation and dampness. This guide discusses what causes the condensation, how to make a correct diagnosis, and what the householder can do to cure the problem. It outlines simple measures including improving ventilation, heating and insulation. GR7 

Treating dampness in basements
Several problems can be encountered following conversion of a basement in an older property into habitable accommodation: the most serious is probably dampness because early forms of basement construction had no damp-proofing. Although basements used as kitchens and servants’ rooms were reasonably dry, many others suffer from penetrating dampness, mould growth and deterioration of timbers. This is unacceptable for habitable rooms. This Good Repair Guide gives advice to builders and householders on ways of treating dampness in basements by treating internal surfaces. GR23 

Treating rain penetration in houses
This Good Repair Guide (one of a series on diagnosing and dealing with dampness and related problems) explains how to determine if rain penetration is the problem; how to pinpoint the exact route the water is taking; and how to remedy the problem.  GR8 

Treating rising damp in houses
Householders, and even some surveyors, are too quick to assume that problems with dampness are caused by rising damp. In fact, true rising damp is not very common. Because the remedies for rising damp are so expensive, it is doubly important to ensure the diagnosis is correct before starting work. This Guide presents a systematic approach to the problem. GR6 

Understanding dampness
Dampness is a continuing cause of distress to building occupants. It is possibly a source of or a contributor to illness, and it encourages deterioration in the fabric of a building. Despite all the technical advice that has been published in the past there is still a significant set of problems. This book seeks to address them. With an emphasis on existing buildings and some coverage of the design of new build, this publication lists the causes of dampness and explores its effects. It also provides remedial measures. Topics covered include: Visible and hidden effects of dampness; Measuring moisture; Condensation; Rain penetration; Rising damp and more. A highly useful reference for surveyors, architects, builders, facilities managers and students of those professions. BR466

This guidance is intended for those involved in the design and construction of buildings. IP2/05 

Modelling condensation and airflows in pitched roofs
The risk of condensation in cold pitched roofs is dominated by airflows from the living areas of a house into the loft and through the loft to the outside. The effect of these airflows is excluded from the current British Standard procedure for assessing interstitial condensation risks. This paper discusses the factors that are necessary to construct a realistic model to predict condensation risk in structures with significant airflows, and describes the sources of the data needed to run such a model and the resulting outputs. IP5/06

Temperature and humidity in batten voids
Changes in construction methods and materials, such as breathable membranes and high peformance thermal insulation, introduce new issues for the integrity of buildings. This Information Paper describes measurements within batten voids to determine the conditions in which condensation occurs; and whether the condensation leads, in turn, to increased levels of moisture in battens. In theory, there could be risks of condensation in batten voids which may affect the moisture content of battens. IP20/01 

Treating condensation in houses
Over 2 million UK homes suffer from widespread condensation and dampness. This guide discusses what causes the condensation, how to make a correct diagnosis, and what the householder can do to cure the problem. It outlines simple measures including improving ventilation, heating and insulation. GR7 

Treating dampness in basements
Several problems can be encountered following conversion of a basement in an older property into habitable accommodation: the most serious is probably dampness because early forms of basement construction had no damp-proofing. Although basements used as kitchens and servants’ rooms were reasonably dry, many others suffer from penetrating dampness, mould growth and deterioration of timbers. This is unacceptable for habitable rooms. This Good Repair Guide gives advice to builders and householders on ways of treating dampness in basements by treating internal surfaces. GR23 

Treating rain penetration in houses
This Good Repair Guide (one of a series on diagnosing and dealing with dampness and related problems) explains how to determine if rain penetration is the problem; how to pinpoint the exact route the water is taking; and how to remedy the problem.  GR8 

Treating rising damp in houses
Householders, and even some surveyors, are too quick to assume that problems with dampness are caused by rising damp. In fact, true rising damp is not very common. Because the remedies for rising damp are so expensive, it is doubly important to ensure the diagnosis is correct before starting work. This Guide presents a systematic approach to the problem. GR6 

Understanding dampness
Dampness is a continuing cause of distress to building occupants. It is possibly a source of or a contributor to illness, and it encourages deterioration in the fabric of a building. Despite all the technical advice that has been published in the past there is still a significant set of problems. This book seeks to address them. With an emphasis on existing buildings and some coverage of the design of new build, this publication lists the causes of dampness and explores its effects. It also provides remedial measures. Topics covered include: Visible and hidden effects of dampness; Measuring moisture; Condensation; Rain penetration; Rising damp and more. A highly useful reference for surveyors, architects, builders, facilities managers and students of those professions. BR466

This is unacceptable for habitable rooms. This Good Repair Guide gives advice to builders and householders on ways of treating dampness in basements by treating internal surfaces. GR23 

Treating rain penetration in houses
This Good Repair Guide (one of a series on diagnosing and dealing with dampness and related problems) explains how to determine if rain penetration is the problem; how to pinpoint the exact route the water is taking; and how to remedy the problem.  GR8 

Treating rising damp in houses
Householders, and even some surveyors, are too quick to assume that problems with dampness are caused by rising damp. In fact, true rising damp is not very common. Because the remedies for rising damp are so expensive, it is doubly important to ensure the diagnosis is correct before starting work. This Guide presents a systematic approach to the problem. GR6 

Understanding dampness
Dampness is a continuing cause of distress to building occupants. It is possibly a source of or a contributor to illness, and it encourages deterioration in the fabric of a building. Despite all the technical advice that has been published in the past there is still a significant set of problems. This book seeks to address them. With an emphasis on existing buildings and some coverage of the design of new build, this publication lists the causes of dampness and explores its effects. It also provides remedial measures. Topics covered include: Visible and hidden effects of dampness; Measuring moisture; Condensation; Rain penetration; Rising damp and more. A highly useful reference for surveyors, architects, builders, facilities managers and students of those professions. BR466
