Definitions

• the invention concerns the peripheral load-bearing wall of the low-energy building consisting of metal vertical and horizontal beams, thermal insulating and acoustic and fire-protection layers, moisture stops and coverage layers.
• wooden structures have also been represented in the market nowadays; their walls consist of the basic wooden frame (or panel) structure, which is jacketed from both sides with load-bearing board materials, e.g. wood-chip, chipboard or plywood boards, plaster-fibre boards, etc.
• load-bearing board materials e.g. wood-chip, chipboard or plywood boards, plaster-fibre boards, etc.
• sandwich filling between the boards which consists of thermal and acoustic insulation, moisture stop or, as the case may be, air gap, and the facade thermal insulation system is usually attached from the external side on the boards.
• the steel load-bearing structures have higher strength, better fire-protection properties, smaller condensation of humidity (higher dew point) and also better acoustic insulation properties.
• the metal structures consist of a set of vertical and horizontal beams with reinforcements and jacketing.
• the beams may be thick-walled, e.g. with the cross-section "L” or "U”, as it is described e.g. in the utility design no. 17 159, which proposes the elimination of cold bridges in connections and proposes to relieve the beams by means of relieving holes.
• the pre-fabricated profiles are thin-walled sheet "C” profiles and "U” profiles, which have different shapes at the webs, crossbars and beams.
• Some profiles are provided with relieving holes but their disadvantage consists in the fact that the load-bearing system does not comply with some requirements for acoustic insulation.
• peripheral wall systems consists in the fact that they do not include such combination of load-bearing, filling and jacketing items, which would feature a simple and easy installation directly in the construction site and, at the same time, high thermally and acoustic insulating properties, long service life and high applied value, which would be suitable for application to energetically economical or low- energy buildings.
• peripheral wall of the energetically economical or low-energy building which consists of a frame from thin-walled galvanized "C" profiles and "U” profiles, and its nature consists in the fact that the inner coverage layer consists of two layers of plasterboard attached to the frame, behind which a moisture stop is applied; the insulation layer consists of the board from mineral felt with the thickness of 150 mm and the external layer consists of load-bearing plaster-fibre boards or wood-fibre boards, on which the mechanically anchored and additionally glued contact thermal insulation system is applied with thermal insulation boards from mineral felt with the insulation thickness from 100 to 240 mm.

• the first layer of plasterboard covers the connections of the second layer of plasterboard.

• the thickness from 12.5 to 18 mm is sufficient for anchoring the contact thermal insulation system and covering the joints improves the thermal and acoustic insulation.
• the advantage of the peripheral wall according to the technical solution in comparison with other known solutions, consists especially in the fact that simple and easy installation directly in the construction site is possible and the peripheral wall features extraordinary fire resistance in case of fire outside the building and very good fire resistance of the actual load- bearing structure in case of a fire inside the building.
• the material composition of the peripheral wall complies with the standard requirements for energetically economical and low-energy buildings, including the accumulation nearing the traditional materials (brick etc).
