Definitions

  • the invention relates to insulating elements for cavity walls.
  • a cavity wall generally comprises an inner block course and an outer course such as a brick course with a cavity between the courses. It is known to use foam boards as insulation material for location in the cavity. In some cases the foam board is partially covered by a cover of an impact resistant material. For optimum insulation performance a cavity should be filled with such boards. The joint between the boards however presents a problem as such joints are potential leak paths for loss of heat and are also at risk of water penetration. Attempts to date to solve this problem have not been entirely successful.
  • an insulating element for a cavity wall comprising an insulation foam board having a first facing on one side and a second facing on an opposite side, and an impact resistance cover covering over one of the facings, the impact resistant cover having side overlap engagement portions on opposed sides thereof for overlapping engagement with corresponding overlap portions of adjacent like insulating elements.
  • the insulating element comprises an end overlap portion on at least one end of the impact resistant cover for overlapping with an end portion of the impact resistant cover of adjacent like insulating elements.
  • the end overlap portion may comprise a flange which extends beyond the adjacent edge of the insulation board.
  • the flange comprises at least one slot to accommodate a wall tie.
  • the flange may comprise a plurality of spaced-apart slots.
  • the cover comprises an intumed portion which extends over an edge of the insulation board.
  • the intumed portion may comprise a recess to accommodate a wall tie.
  • the intumed portion may comprise a plurality of recesses to accommodate wall ties.
  • one or both of the facings is perforated.
  • the or each facing may be pre-perforated as described in our GB2436313A .
  • At least one of the facings may comprise a substantially gas impermeable material.
  • the facing may comprise a metallic foil such as an aluminium foil.
  • the facing may be a laminate such as a metallic foil laminated onto a glass tissue or a metallic foil laminated onto a Kraft paper.
  • the invention also provides an insulation system for a cavity wall comprising a plurality of insulating elements according to the invention.
  • FIG. 3 illustrates two of the insulating elements 1 in situ filling a cavity 2 between an inner block course 3 and an outer course such as a brick course 4 of a cavity wall.
  • the insulating element 1 comprises an insulation foam board 10 having inner and outer facings 11, 12 on a foam core 17.
  • the foam board 10 has a first face which is covered by the outer facing 11 and an inner face which is covered by the inner facing 12.
  • the foam board also has two opposed sides 13, 14 and upper and lower ends 15, 16 respectively.
  • the foam may be of a suitable insulating foam such as polyurethane, polyisocyanurate or phenolic foam. Particularly preferred is closed cell phenolic foam because of its high insulation properties.
  • the facings 11, 12 may be of any suitable material. There may be of one layer or a laminate of two or more layers. For enhanced insulation properties it is preferred that the outermost face of the facings 11, 12 is of a metallic material such as aluminium foil.
  • One or both facings is preferably perforated to shorten board drying time on manufacture as described in GB2436313B1 and GB2478228B1 .
  • the outer facing 12 of the board is covered by a pre-formed cover 20 of a high impact resistant material such as HIPS (high impact resistant polystyrene).
  • the impact resistant cover 20 has side overlap engagement portions 21, 22 on opposed sides thereof for engagement, on overlapping with corresponding side overlap portions 21, 22 of the cover of like insulating elements as illustrated particularly in Figs. 5 to 8 .
  • the cover 20 has a flange 25 extending from one side and the flange 25 has an elongate recessed portion 26 which defines the first side overlap portion 21.
  • the second overlap portion 22 comprises an elongate raised rib 27 on the opposite side of the cover 20.
  • the rib 27 is of complementary shape to that of the recess 26 so that on assembly, the rib 27 and recess 26 of adjacent insulating elements are interengaged to form a joint as illustrated particularly in Figs. 6 to 8 .
  • the cover (including the flange 25) has an intumed portion 30 which extends over the upper end 15 of the foam board.
  • the cover also has a downwardly projecting flange 31 extending beyond the lower end 16 of the insulating board. In use, the flange 31 overlaps with the cover at the upper end of an adjacent insulating element as illustrated particularly in Figs. 3 , 4 and 9 .
  • the flange 31 has a plurality of spaced-apart slots 35 which are sized and shaped to facilitate passage of the flange over an arm 37 of a wall tie as illustrated particularly in Fig. 21 .
  • the intumed portion 30 of the cover 20 also has a plurality of spaced-apart recesses 38 which accommodate passage of a wall tie arm 37. The recesses 38 and the slots 35 are located to accommodate wall ties even when adjacent insulating elements are overlapped as illustrated in Fig. 4 .
  • the exposed face of the cover 20 has projecting formations or flutes 40 for moisture run-off.
  • the projecting flutes on the face of the panel have been so located that they interlock when placed face to face ensuring full protection during storage and transport.
  • the cover elements are overlapped and inter-engaged at the joints therebetween they are easy to position and fix, in use.
  • the cover provides complete resistance to potential water ingress via the external brick/block leaf.
  • the provision of the cover element also eliminates the need to form expensive, complicated and potentially vulnerable joints in the core foam.
  • the vertical engineered joint eliminates the risk of horizontal water penetration due to the interlocking feature of the design. This engineered joint also provides strength and stability to the extending cover flange
  • the cover provides a 'hood' over the wall tie recess and protects this vulnerable point, in terms of water ingress, where the cover is penetrated by the wall ties. This unique feature directs any water penetrating the outer leaf away from the wall tie locations and onto the less vulnerable areas of the panel
