Measured Results of Thermal Conductivity value is initial thermal conductivity coefficient (λ a), is located at have passed through in the changeless constant temperature and humidity cabinet of certain humiture
Thermal coefficient after a certain period of time is thermal coefficient (λ b) after deterioration, and has evaluated the thermal coefficient variable quantity as its difference
(λ b- λ a).In the case that spacing 53a and 53b be 3mm it is below, thermal coefficient variable quantity be 0.5mW/mK hereinafter, but with
Spacing becomes bigger than 3mm, and thermal coefficient variable quantity increases.In the case where spacing is 3.5mm, thermal coefficient variable quantity becomes

In the range of~160 °, thermal coefficient variable quantity be 0.5mW/mK hereinafter, but departing from the range, heat conduction system
Number variable quantity increases 2 times or more.Therefore, in order to inhibit thermal coefficient through when deteriorate, angle 55 is preferably in 90~
In the range of 160 °.In order to cut off the glass fibre for being sandwiched into heat-fused portion 5a, need that angle 55 is made to be 160 ° or less.If due to
Angle 55 is then fallen within the scope of the elastic deformation area of glass fibre more than 160 °, so glass fibre can not be cut off.Another party
Face, it is believed that if angle 55 is 90 ° discontented, the vapor deposition of gas-barrier layer, metal foil crack, table of the gas from sealing 5
The gas penetration speed that face penetrates increases.Therefore, the warp of Vacuumed insulation panel 1 preferably makes phase after degraded thermal performance in order to prevent
