Abstract: A Multi Chamber gas filled building panel is structured of essentially planar parallel inner (1) and outer (2) plates. Between the inner (1) and outer (2) plates, preferably of glass, there is at least one chamber (3) filled with insulation gas, the chambers (in case of plurality thereof) divided between themselves using dividers (4) usually manufactured of transparent polymer foils. The building panel according to this invention in addition features at least one air-filled chamber (5) which is connected to surrounding air via opening (6) enabling inner volumetric expansion and contraction of insulation gas.

Abstract: The building panel is structure of outer (11) and inner (12) plate where there is intermediate insulation space between the plates (11) and (12). In this space there can by any kind of thermal and/or sound insulation which does preferably not form solid structure in connection with plates (11) and (12). The connection (1) forms connection between plates (11) and (12). The connection (1) is implemented at least along the longitudinal part of panel frame. Further the connection (1) comprises the attached polymer-based profile (2) or stack of spacers (7).

Abstract: A gas filled panel (GFP) intended for general use, especially in construction, mostly in prefabricated building envelopes, i.e., integrated facades. A panel of the first embodiment is characterized in that it is a two- or more-chamber panel made of at least approximately plan parallel chambers with a mutual distance larger than or equal 8 mm, preferably between 8 and 12 mm, filled with insulation gas, which is a binary or ternary mixture of gases from hydro-fluorocarbons (HFC), carbon dioxide and argon and the mixture has an average molecular mass higher than 50 and lower than 71. A panel of the second embodiment is characterized in that it is a three- or more-chamber panel made of at least approximately plan parallel chambers with a mutual distance larger than or equal 18 mm, preferably between 18 and 22 mm, filled with insulation gas, or a mixture of gases having an average molecular mass higher than 38 and lower than 50.
