Abstract
Non-planar integral evacuated insulation panels and a method for making these by providing grooves in the filler material prior to enveloping said filler and forming by evacuating, which method allows to make evacuated insulation panels of specific non-planar shapes depending on the depth and shape of the grooves.
Claims10
Method for producing a non-planar rigid integral evacuated insulation panel comprising an insulating foam enveloped in a substantially gas impermeable flexible vessel by enveloping a flat panel of insulating foam in the substantially gas impermeable flexible vessel, evacuating the enveloped insulation foam and sealing, characterised in that at least one groove is provided in the insulating foam prior to evacuation.
