Report about testing the warmth ducting coefficient of one-wing window with AL-frame prototype without termical interrupt
On the basis of results of testing of one-wing window with AL-frame prototype without termical interrupt, in "Alpro" sistem, with dimensions of 900 mm x 1500mm, glazed with termo-isolation flot glass 4+12+4 mm, conducted according to JUS U.J5.060 (1983) standard, with rated values of warmth ducting resistance according to JUS U.J5.600 (1998), the following valueswere obtained:
1. Termo-isolation glass 4+12+4, flot
warmth ducting resistance: Rs = 0.22 m2 K/W
warmth ducting coefficient: Ks = 2.56 W/(m2K)
2. Frame
warmth ducting resistance: Ro = 0.04 m2 K/W
warmth ducting coefficient: Ko = 4.76 W/(m2K)
Equivalent warmth ducting coefficient of prototype, under relative surface participation glass and frame, with window surface of fs = 0.69 and fo = 0.31,
equals: K =3.24 W/(m2K).
