<p>The method involves bringing a heat and/or insulation material medium from outside into cavities of a hollow profile frame. The insulating material is filled into the cavities by positive pressure and sucked from the cavities by negative pressure. The cavities are secured from inadvertent withdrawing of the insulating material particles by a support device i.e. net. A cold -, heat- and/or sound-insulation filling is carried out by vacuum sealed tubes made of PVC material or by insulating foams, silicone materials and foam materials, staffs, strips or damming wool.</p> |
