Objective
The results of a previous intercomparison in which measurements of heat transmission were made on two different sized double-glazed window units (without frames) showed rather large discrepancies between the different laboratories. In this latest intercomparison, seven double-glazed reference panel units and seven double-glazed framed windows were circulated and measurements were made under commonly agreed and very detailed specified conditions. The reference panels had a rigid foam insulation material between the panes because a particular problem in the previous intercomparison had been the variation in the thickness of the airgap between the panes. Each participating laboratory made measurements on one panel unit and one window using a guarded hot box apparatus.
RESULTS
The standard deviation about the mean of the standardised U-values was about 5% for the reference panels and about 7% for the windows. Excluding outliers where reasons for discrepancies could be postulated, the range of the standardised U-values was 2.03 to 2.29 W/m{2} K for the reference panels and 2.46 to 2.84 W/m{2} K for the windows.

Funding Scheme
Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
