The profiles of glassfibre reinforced polyester are made by Fiberline Composites A/S, Barmstedt Allé 5, DK-5500 Middelfart and manufactured by DFE A/S, Hjortevej 3, DK-7800 Skive.
In Denmark, energy labelling is statutory when selling and letting buildings and also every five years for large buildings.
Ueff is the effective U-value, deducted the solar input assuming an average orientation of the compass.
Ueff = Uw - 2,2 x g x Ar/Av
Uw value for the total window in W/m2K
g solar transmittance in %
Ar glass area in m2
Av area of the window in m2
Uw = (Ag * Ug + Af * Uf + Ig * Ψg) / (Ag + Af )
Ug
= U-value for the glass measured at the center, W/m2K
Uf
= U-value of the frame in W/m2K
Ψg
= energy loss along the edge of the glass in W/m2K
Ag = Glass area in m2
Af = Frame area in m2
Ig = Glas perimeter in m
Pilkington Spectrum.
Pilkington Spectrum 2 On-line calculates the energy label for single-, double- and triple-glazed panes U/LT/g for panes, where
U = Thermal transmission in W/(m2K),
LT = Light transmittance in % and
g = Total solar energy transmittance in %.
I = First glazing
II = Second glazing
III =Third glazing
mm = Optimal size of gas-filled cavity in mm
C = Pilkington Optifloat Clear, Floatglas , 4 mm, non-coated
K = Pilkington K Glass, Floatglas , 4 mm, coated
O = Pilkington Optitherm S3, Floatglas , 4 mm, coated
Price per 23. September 2009. Price difference between argon and krypton is 66 DKK per standard double-glazed pane per mm gas or 36 DKK per sqm for 1 mm gas.
Price of a double-glazed window with krypton costs 315 DKK more than the same with argon per sqm.
