La conductiviteacute thermique (λ)
La conductiviteacute thermique est le flux de chaleur traversant un mateacuteriau drsquoun megravetre drsquoeacutepaisseur
pour une diffeacuterence de tempeacuterature de 1 degreacute entre les deux faces Elle srsquoexprime en Wms
Cette valeur permet de quantifier le pouvoir isolant de chaque mateacuteriau Plus elle est faible
plus le mateacuteriau sera isolant
La reacutesistance thermique (R)
La reacutesistance thermique est utiliseacutee pour quantifier le pouvoir isolant des mateacuteriaux pour une
eacutepaisseur donneacutee Elle srsquoexprime en msup2KW Une paroi est en theacuteorie plus isolante si son R est
eacuteleveacute
Le coefficient de transmission surfacique (U)
Pour caracteacuteriser une paroi on utilise souvent le coefficient de transmission surfacique (U) Ce
coefficient correspond a lrsquoinverse de la reacutesistance thermique R Il srsquoexprime en Wm2K Il repreacute-
sente le flux de chaleur a travers 1m2 de paroi pour une diffeacuterence de tempeacuterature de 1degC
entre les deux environnements seacutepares par la paroi Plus U est faible plus la paroi est isolante
Lrsquoinertie Thermique
Linertie thermique est la capaciteacute dun corps a stocker de la chaleur Elle est caracteacuteriseacutee par la
capaciteacute thermique Ce comportement des mateacuteriaux est un principe fondamental pour la con-
ception bioclimatique des bacirctiments Elle contribue au confort de lhabitation en atteacutenuant les
variations des pointes de tempeacuteratures En hiver une forte inertie permet demmagasiner la
chaleur de la journeacutee due aux apports solaires puis de la restituer plus tard dans la journeacutee lors-
que la tempeacuterature exteacuterieure commence a chuter En eacuteteacute une forte inertie lieacutee a une ventila-
tion nocturne permet datteacutenuer les surchauffes durant la journeacutee

La conductiviteacute thermique (λ)
La conductiviteacute thermique est le flux de chaleur traversant un mateacuteriau drsquoun megravetre drsquoeacutepaisseur
pour une diffeacuterence de tempeacuterature de 1 degreacute entre les deux faces Elle srsquoexprime en Wms
Cette valeur permet de quantifier le pouvoir isolant de chaque mateacuteriau Plus elle est faible
plus le mateacuteriau sera isolant
La reacutesistance thermique (R)
La reacutesistance thermique est utiliseacutee pour quantifier le pouvoir isolant des mateacuteriaux pour une
eacutepaisseur donneacutee Elle srsquoexprime en msup2KW Une paroi est en theacuteorie plus isolante si son R est
eacuteleveacute
Le coefficient de transmission surfacique (U)
Pour caracteacuteriser une paroi on utilise souvent le coefficient de transmission surfacique (U) Ce
coefficient correspond a lrsquoinverse de la reacutesistance thermique R Il srsquoexprime en Wm2K Il repreacute-
sente le flux de chaleur a travers 1m2 de paroi pour une diffeacuterence de tempeacuterature de 1degC
entre les deux environnements seacutepares par la paroi Plus U est faible plus la paroi est isolante
Lrsquoinertie Thermique
Linertie thermique est la capaciteacute dun corps a stocker de la chaleur Elle est caracteacuteriseacutee par la
capaciteacute thermique Ce comportement des mateacuteriaux est un principe fondamental pour la con-
ception bioclimatique des bacirctiments Elle contribue au confort de lhabitation en atteacutenuant les
variations des pointes de tempeacuteratures En hiver une forte inertie permet demmagasiner la
chaleur de la journeacutee due aux apports solaires puis de la restituer plus tard dans la journeacutee lors-
que la tempeacuterature exteacuterieure commence a chuter En eacuteteacute une forte inertie lieacutee a une ventila-
tion nocturne permet datteacutenuer les surchauffes durant la journeacutee

10 INTRODUCTION
At the request of NUDURA Corporation Exova was retained to re-calculate the theoretical thermal resistance value of a wall system using standard theoretical values published in the ASHRAE Fundamentals Handbook 2009
The modified calculations are based on the clientrsquos intentions to change the 25 inch thick EPS foam density from 13 lbft3 to 14 lbft3 on the original ldquoNUDURATM Insulated Concrete Form Wall Systemrdquo
The initial calculations and assumptions are shown in the Appendix A ldquoBodycote Materials testing Canada Inc Report No 01-06-M0379-3 Revision 1rdquo
The wall system was assigned the following Exova Identification No

Thermal Resistance Calculations of NUDURAtrade Insulation Wall Systems Page 2 of 3 for NUDURA Corporation Report No 10-06-M0083 B
10 INTRODUCTION
At the request of NUDURA Corporation Exova was retained to re-calculate the theoretical thermal resistance value of a wall system using standard theoretical values published in the ASHRAE Fundamentals Handbook 2009
The modified calculations are based on the clientrsquos intentions to change the 25 inch thick EPS foam density from 13 lbft3 to 14 lbft3 on the original ldquoNUDURATM Insulated Concrete Form Wall Systemrdquo
The initial calculations and assumptions are shown in the Appendix A ldquoBodycote Materials testing Canada Inc Report No 01-06-M0379-3 Revision 1rdquo
The wall system was assigned the following Exova Identification No
Client Wall-System Configuration Exova Identification No
NUDURATM Insulated Concrete Form Wall Systemrdquo 10-06-M0083 B
20 PROCEDURE
ASHRAE Fundamentals handbook 2009 Chapters 23 25 and 26 were utilized to calculate the theoretical thermal resistance value of the wall systems It should be noted that the values calculated in this report are the apparent value only and may change significantly when used as a system
