Definitions

• This invention relates to an outer wall intended for buildings, preferably dwelling houses, the wall comprising an outer portion, an intermediate portion comprising insulating material and an inner portion.
• Outer walls in houses built in later time as a rule are constructed in that way that the intermediate portion comprises an insulating layer of inorganic material, the layer having a plastic foil on its innerside, which foil is impermeable to air.
• the known wall is very complicated regarding its construction and is different from that one according to this invention.
• the known wall construction has for instance a centrally positioned partition wall, which is impermeable to air and moisture.
• This invention intends to eliminate the problems with known technique and provide a wall construction, which to a high extent improves the air environment indoors for persons having allergic, asthmatic and similar troubles. Due to this invention the fresh air environment existing in houses of old time is provided, but with the essential difference that the drawback with a draughty environment is eliminated.
• the new wall construction is characterized by the fact that the intermediate portion on that part, which is directed towards the outer portion, and on that part, which is directed towards the inner portion, has a cardboard material, which is made in such a way that it can allow air to pass through, and that the insulating material comprises an organic material, preferably sawdust or the like, with the quality to be able to receice and emit moisture while maintaining its insulating ability.
• the new outer wall comprises an outer portion 1, an intermediate portion 2 and an inner portion 3, which is intended to represent a wall in the room 4.
• the intermediate portion 2 is delimited on its outer side as well as on its innerside of a ventilating cardboard 5, 6, which are made in that way that they can allow air to pass through.
• the intermediate portion 2 further comprises outer, vertical beams 7 and inner vertical beams 8, which are held together by means of horizontal distance plates 9, whereby there is a predetermined distance between the two cardboard layers 5, 6, which distance accordingly constitutes the width of the intermediate layer 2.
• the space, which accordingly exists between the two cardboard layers, is intended to be filled with an insulating material.
• the insulating material comprises an organic material, preferably sawdust or wood fibre dust, and this material fills out the entire space between the two ventilating cardboard layers 5, 6 and accordingly also the space between the two opposite beams 7, 8.
• the beam construction leads to that the sawdust/wood fibre dust can expand and shrink without creating air pockets between the inner- and the outer side of the intermediate portion 2.
• the distance plates 9 are vertically displaced in relation to each other, which has the consequence that the sawdust is allowed to move everywhere in the insulating intermediate layer. Due to that fact the risk is eliminated that cavities/air pockets shall be able to arise and by that a reduction of the insulating ability.
• the insulating material has the ability to receive and emit moisture in connection with the air movements through the wall but still maintain its insulating ability. Due to the mentioned air movement all tendencies to mould formation in the insulating material are eliminated, and therefore the indoor air becomes very tolerable for persons having allergic or asthmatic problems.
• the outer portion comprises a cover board 10, a gypsum wallboard 11 and intermediate, horizontal beams 12, which parts are fastened to each other in a suitable way.
• the outer cardboard layer 5 of th ⁇ intermediate portion 2 is connected with the gypsum wallboard 1 1 of the outer portion 1.
• the inner portion 3 comprises a gypsum wallboard
