1 Introduction This document details the thermal performance calculation of the Bi-folding door configuration as detailed below. The frame profile results detailed below are provided by computer simulation using LBL software program THERM 5.2 and validated against proofs in Annex D (D1 to D10) of BS EN ISO 10077-2:20012. The frame profile results detailed below are provided from methods contained in BS EN ISO 10077-1:2006 and in accordance with thermal transmittance requirements detailed in BS EN 14351-1:2006 +A1:2010.
