Introduction

Heat Loss from JunctionsThermal bridging occurring at the junctions of a building’s planar elements (i.e. between roofs, walls, openings and floors) can add significantly to a building’s total fabric heat loss.

Higher heat flows occur at junctions due to complex geometries, or from the use of materials with a higher thermal conductivity than the adjacent materials. This can cause localised reductions of internal surface temperatures, which can lead to surface condensation and mould growth problems. Good design detailing can help to avoid these issues. The details in this guidance have been developed with the aim of being buildable, achieving good thermal performance and minimising risk.

Linear thermal bridging describes the heat–loss occurring at junctions between elements e.g. between a wall and floor, or around openings e.g. at sills, lintels and jambs. A ψ–value (psi–value) is the heat loss through a junction, which is additional to the heat flow through the adjoining plane elements, and is measured in W/m.K.

ψ–values are not taken into account in U–value calculations. Instead they are taken into account separately in the calculation methodologies used to assess the operational CO2 emissions of buildings e.g. SAP in the UK for domestic purposes, or SBEM for non–domestic.

Junctions & Building ComplianceThere are three possibilities for specifying thermal bridging:

a. details conform with Approved Design Details or another government approved source involving independent assessment of the construction method. In this case, use ψ–values from the approved column on Table K1, or from the approved source;

b. ψ–values calculated by a person with suitable expertise and experience in accordance with BRE IP 1/06 and BR 497 (Conventions for Calculating Linear Thermal Transmittance and Temperature Factors). In this case, use those calculated ψ–values along with the length of each junction; or

c. if neither of the above applies, use a global default value for overall heat losses in the energy calculation to take account of the heat loss due to thermal bridging (a value of 0.15 W/m².K is added to overall elemental losses, making it harder to achieve compliance).

A combination of details from a. and b. above can be used and where some details are missing, the ψ–values from the ‘default’ column in Table K1 can be used.

The ψ–values in this document have all been calculated by persons with suitable expertise and experience as per option b. above.

Thermal Modelling of Junctionsψ–values have been created for the major junctions involving Kingspan Kooltherm® K106 Cavity Board, following the guidelines in BR 497.

All thermal modelling work was undertaken by Competent Thermal Modellers, who have successfully completed training and portfolios with ACD Certification Ltd and are experienced in thermal modelling of junction heat losses, on behalf of Kingspan Insulation Ltd.

The assessors who undertook the thermal modelling in this document are:

• Mr Jonathan Ducker

• Miss Samantha Lloyd

All of the calculated ψ–values for the Kingspan Insulation junction details are better than the default ψ–values for the accredited details as given in BRE IP 1/06 and Table K1 of SAP 2012.

Critical Temperature FactorsReasonable provision to avoid surface condensation, or mould growth occurring as a result of thermal bridges, is to demonstrate that details achieve a temperature factor that is no worse than the performance set out in BRE IP 1/06.

The temperature factor is a property of the construction, surface resistances and internal and external temperatures. It is used to assess the risk of surface condensation or mould growth. This parameter has been provided for all of the junction variants.

In all cases the calculated values are higher than the critical temperature factor for dwellings (fCRsi of 0.75) as given in BRE IP 1/06, which limits the risk of surface condensation or mould growth. Higher humidity condition buildings, for example swimming pools (fCRsi of 0.90), may require alternative details and constructions.

All of the modelled Kingspan Kooltherm® K106 Cavity Board details achieve acceptable temperature factors in accordance with BRE IP 1/06.

Calculation MethodologyThe thermal modelling of the Kingspan Kooltherm® K106 Cavity Board details was undertaken using two transient and steady–state heat transfer software packages produced by Blocon (as appropriate for the detail). HEAT 2 was used for the two–dimensional details and HEAT 3 for the three–dimensional details.

The modelled U–values and underfloor temperatures for suspended and beam and block floors were determined using the STROMA U–value calculator.

Junctions were modelled using a 90 mm thickness of Kingspan Kooltherm® K106 Cavity Board in an overall 100 mm cavity, with a 10 mm residual cavity air–space, and with a variety of internal leaf blockwork types, including three variations of light–weight blockwork (0.11 W/m.K, 0.15 W/m.K and 0.19 W/m.K), a version with medium dense blockwork (0.51 W/m.K) and one with dense blockwork (1.13 W/m.K).

How to Use these DetailsAdditional modelling was undertaken, which looked at various external leaf and internal finishes (see section below).

The detail sheets include a process sequence and also guidance on how to achieve a good level of air–tightness.

The ψ–values and temperature factors are provided for different bands of internal leaf blockwork conductivity. Where a different conductivity blockwork is used, performance can be inferred from the poorest, closest blockwork modelled.

The ψ–values cited may be used in calculations of building heat loss, where the principles of construction and key element specifications have been followed.

Limitations & Applicability of ModellingThe ψ–values could be reasonably used whenever the external leaf of the construction is constructed either from external brickwork, or stonework, or where the external leaf is rendered blockwork, and when the external leaf is not less than 100 mm in thickness. The ψ–values can also be considered to be valid to two significant figures where the internal finish is either plaster or plasterboard on dabs, with or without skim.

For junctions around openings (windows and doors), variants have been included covering a 30 mm overlap, between the window frame and the cavity, and a full overlap (between the frame and cavity), or for a check reveal. Options for both full overlap and for a check reveal were thermally modelled and as the results were very similar, these details reflect the worst case result of the two.

Calculated ψ–values can be used by energy assessors for buildings constructed in accordance with associated details for buildings constructed in England, Scotland, Wales and Northern Ireland.

Where proposed constructions significantly differ from the enclosed process sequences, or use alternative materials, these ψ–values and temperature factors should not be used.

These details represent typical detailing to achieve a good level of thermal performance, however the details included in this document may not be suitable for use in all circumstances. Where there is any uncertainty, Building Control Body (BCB) requirements and advice should always be sought and followed. All other site requirements and relevant building regulations must be taken into consideration when implementing the details.
