Definitions

  • the present invention relates to the thermal insulation of building structures.
  • One method of insulating building structures involves securing to the rafters, walls or ceiling joists, layers of sheet material which are spaced apart over a substantial part of their area.
  • the air trapped between the layers has favourable insulating properties attributable to limited convection.
  • a significant improvement is obtained by employing a sheet material which is thermally reflective, at least on one face, and thereby reducing the transmission by radiation.
  • An object of the present invention is to provide an improved material for use in the method aforesaid.
  • a material for the thermal insulation of building structures which comprises a plurality of webs of a flexible sheet material and a pair of side members, to the central portions of which the edge ⁇ regions of the webs are secured, with the faces of the webs in spaced-apart relationship, the side members having border parts which project beyond the central portions and are foldably linked to the central portions, the arrangement being such that the webs and the side members may be arranged in a substantially flat state with at least one of the webs pleated, may be opened from the substantially flat state to produce the spaced-apart relationship and the border parts of the side members may be folded away from the webs for securing the material in an operative position.
  • the border parts and the central portions of the side members join together along creases. It is then a simple matter to fold the border parts, usually through 90 * , to lap them over struts between which the material is fitted.
  • At least one side of the material is provided with a longitudinally-extending strut and the border parts are secured thereto.
  • This arrangement renders it a simple matter to apply the material to existing structures, e.g. to line the v-shaped, or other shaped, roof of a factory building or to install a suspended ceiling.
  • the plurality of webs provides a pair of outer webs, the depth of the strut between a pair of opposite faces thereto is substantially equal to the spacing between the pair of outer webs, and the border parts of the pair of outer webs are secured over the opposite faces of the strut by pinning means.
  • the material may be located in the required position by hanging it by means of wires, chains or other tensile material connecting the struts with .the roof or other support and, for this purpose, may be provided with projecting heads adapted to be secured to means for suspending the material.
  • One convenient arrangement is to provide the heads in the form of hooks or eyelets.
  • a metal facing is provided for at least the upper side of the strut, the facing having, distributed along its length, pairs of communicating' slits, the material between which is deformable to provide spikes for securing the border parts of the material to the strut.
  • This facing may also be provided with holes for insertion, through into the strut, of components for attachment to means for suspending the material.
  • Figures 5 and 6 as used in a modification of the arrangement of Figures 3 and 4, and Figure 8 shows, on an enlarged scale, components used in the arrangement of Figure 7.
  • the material of Figures 1 and 2 is in the form of a pair of lengths 1 and 2 of stout card material, e.g. chipboard, formed with longitudinal creases 3. Secured to the region of the card material between the creases are three webs 4, 5 and 6, all of the same width, formed of kraft paper to one face of which is laminated a layer of aluminium foil for the purpose of reflecting thermal radiation or reducing the emission thereof. Webs 4 and 6 are arranged with the foil facing outwardly. Web 5 has the foil on the face which faces web 4.
  • Reflective layers of metal other than aluminium may be employed.
  • paper webs there may be employed webs of a resinous material, e.g. polyvinyl chloride, polyethylene or polypropylene.
  • the webs may have a metal layer physically or chemically deposited or sprayed thereon.
  • the webs are secured to the lengths 1 and 2 by an adhesive applied in bands along the edges of the webs.
  • the adhesive is indicated, for convenience, by points 7. It will be understood however that the bands of adhesive have a finite width.
  • Longitudinal creases 3 enable the outer parts 8 of the lengths of card material to be folded through 90" to be secured to the tops 9 and bottoms 10 of longitudinal struts 11.
  • the width of the outer parts is substantially equal to the thickness of the struts, the two outer parts 8 protruding from opposite faces of the struts overlap. This is a convenient condition in that it allows the two outer parts to be secured in position over the tops and bottoms of the struts in a simple manner, e.g. in the case of wooden struts, by nailing through the outer parts in a single operation.
  • Figure 1 shows slots 12 formed in outer parts 8.
  • the struts 11 are formed of a soft material, e.g. foamed polystyrene
  • the slots of two outer parts may be registered together and then secured by fixing devices 13 and 14 of the generally flat configuration shown in Figure
  • Devices 13 have a locking portion 5 which is pushed through two slots registered together and then rotated through 90 * to join the material.
  • Devices 14 have a similar locking portion 15" which is employed in a similar manner but have a generally circular head 16 formed with a convergent slot 17 leading to a central aperture.
  • the assembly is secured in the required position by wires 18 engaged with the central aperture by sideways passage through slots 17.
  • These wires are readily arranged to position the assembly as required.
  • the wires may have ends which are attached to a roof structure for the construction of a false ceiling.
  • Figure 5 shows a metallic channel structure which may be fitted over the top, and usually also over the bottom, faces of the struts.
  • the sides 19 of the structure receive the struts therebetween and the base 20 fits in contact with the struts' top and bottom faces.
  • Holes 21 permit the passage of the stem parts 22 of securing eyes 23, e.g. for supporting wires.
  • the stems of these eyes have cross-pieces 24 which limit penetration of the card material and the struts.
  • the stems When the stems have been passed through the holes 21, they are secured by self-clamping washers 25 ( Figure 8).
  • the base of the channel is also formed with a series of pairs of slits 26 converging to a common point 27 from a transverse line of weakening 28. This arrangement allows the material between slits 26 to be bent to project outside the channel from base 20 to provide spikes for holding the card material in position.

Abstract

Des matériaux d'isolation thermique de structures de bâtiments comprennent chacun une pluralité de bandes (4, 5, 6) de matériau flexible en lames et une paire d'organes latéraux (1, 2) dont les parties centrales sont attachées aux bords des bandes, les faces de celles-ci étant écartées les unes des autres. Les organes latéraux (1, 2) ont des bords (8) qui s'étendent au-delà des parties centrales et y sont reliés de manière pliable. Les bandes (4, 5, 6) et les organes latéraux (1, 2) peuvent prendre une position sensiblement aplatie, avec au moins une des bandes (4, 5, 6) plissée, et peuvent être ouverts de façon à écarter les bandes les unes des autres. Les bords (8) des organes latéraux (1, 2) peuvent être repliés de façon à s'écarter des bandes et attachés à des solives, par exemple, pour retenir le matériau dans sa position de fonctionnement, où les bandes écartées (4, 5, 6) agissent comme une barrière d'isolation thermique. Les matériaux sont utiles pour des assemblages de plafonds suspendus.
