Definitions

  • the invention relates to an insulation board defined in the introductory part of the independent patent claim.
  • Chipboards having several layers. Each layer is composed of wood chips and adhesive.
  • Chipboards are e.g. wallboards for covering purposes in construction. They are solid and dense in spite of the fact that the chipboard can be bentd to some extend. Insulation elements are normally porous and elastic. That kind of property would be a drawback of chipboards, because covering plates should be strong enough so, that they can be fixed on the wall by nails, screws or so. Insulation property is not important, when we consider utilization of the chipboards. More important is e.g. smooth and firm surface, which is easy to finish such as to paint. Accordingly, the chipboards are not directed to the same purpose as the invention.
  • the prior art FR 887453 discloses a wall construction where multiplied air layers separate in and out parts of the wall.
  • the wall construction has a plurality of wooden frames to each of which a paper sheet is glued and accordingly there are air gaps or layers between paper sheets.
  • a serious drawback of the wall construction is that it is not easy to seal slits between the wooden frames and the support structure around them so, that there are no air leakage; if air can flow through the slits and the whole construction the insulation properties are really poor.
  • the object of the invention is to introduce a novel insulation board manufactured of organic wood fiber pulp pulp, particularly which insulation board has good heat, fire and sound insulation capacities.
  • the insulation board according to the invention is characterized by the novel features enlisted in the characterizing part of patent claim 1.
  • the insulation board therof is moisture resistant and respiring and has good heat insulation capacities.
  • This type of insulation board is particularly suited to be used as heat insulation in wooden buildings; as was mentioned above, the board is made of wood fiber.
  • the insulation board is formed of several porous wood fiber material layers, which are advantageously joined without using any adhesives proper. If an adhesive is used, it is advantageously an ordinary, commercially available wood adhesive.
  • Yet another advantage of the invention is that the wood fiber material layers together form a uniform insulation board without any open air apertures therebetween.
  • the insulation board is porous, flexible and easy to handle. It can be installed in place quickly and compactly as a cut-to-size insulation board for instance in between the vertical spars of a wall.
  • the insulation board 1 comprises a number of overlapping insulation board layers 2.
  • the insulation board layers 2 are made of some porous organic pulp, to which there is possibly added fire retarding agents, anti-rot agents and other similar agents generally used in organic insulants.
  • the said material is advantageously heat fiberized pulp made of pine wood, so-called high-bulk pulp, where the fiber length is in the range 1.0 - 5.0 mm, most advantageously 2.5 - 4.0 mm.
  • the thickness e of the insulation board layer 2 is for instance 2 - 15 mm. In an insulation board layer 2, the fibers are evenly distributed and directed at random to different directions.
  • the insulation board 1 is compiled of for example 10 - 50 insulation board layers 2, in which case the thickness k of the insulation board is for example 25 - 150 mm.
  • the heat insulation capacity of the insulation board 1 is advantageously of the order 0,025 - 0,035 W/mK°.
  • the bulk densiy of the insulation board 1 is of the order 25 kg/m 3 .
  • the border areas 3 of the insulation board 1 are formed of a uniform insulating layer 4; 5; 6, located on a perpendicular plane to the insulation board layers 2, and this insulating layer is made of the same organic pulp.
  • the insulation board 1 is advantageously manufactured as follows. Into wood fiber pulp, such as the said high bulk pulp, there are mixed possible fire retarding agents, such as borax, plus possible anti-rot and anti-mildew agents etc, already at the production stage.
  • the insulation board layers 2 are compressed of wood fiber pulp into porous lamellas with a thickness within the range of a few millimeters, as was maintained above. Thereafter the insulation board 1 is compiled by arranging a number of insulation board layers 2 on top of each other and by compressing the lamellas together and cutting them simultaneously to a predetermined width and length. In between the insulation board layers, there can be provided occasional adhesion spots 7, for instance at spaced points, where some adhesive, advantageously wood adhesive, is applied in order to ensure the gripping of the layers (figures 5 and 6).
  • the border areas 3 of the insulation board 1 are treated with a water spray or a water-glue spray (this being an aqueous glue mixture made of water and a suitable poisonless glue, such as wood adhesive), which decomposes the wood fiber pulp so that the lignin contained therein is at least partly released. In a way it can be said that the border areas 3 melt owing to the effect of the water.
  • the wet wood fiber pulp forms a uniform fiber pulp layer, which at the same time binds the insulation board layers 2 together.
  • a uniform border insulation layer 4 ( Figure 2), transversal to the plane of the insulation board 1 and the insulation board layers 2.
  • the insulation board strip 5 corresponds to the thickness of the insulation board 2 ( Figure 3), or the insulation board strip 6 is wider than the thickness k of the insulation board 1 ( Figure 4).
  • the edges 6a, 6b of the insulation board strip are turned over and attached, for instance glued, to the top and bottom surfaces of the insulation board 1.
