Definitions

  • This invention relates to a flashing construction for forming a weatherproof seal at the junction of a wall and a roof and in particular to an insulated flashing construction providing thermal insulation as well as forming a weatherproof seal at the junction of a wall and a roof.
  • Flashings are used when a roof of abuts against an adjacent wall to inhibit water ingress at the junction of the two.
  • a lead flashing is provided.
  • the flashing extends along the top edge of a roof where it abuts an upstanding wall.
  • the flashing has a portion which is angled down the roof and which is moulded into configuration with the tile contours.
  • a flashing tends to be of a width to cover a number of tiles as there is no requirement for the flashing to be overlapped except at its side edges where it may overlap with an adjacent flashing.
  • One or more sheets of lead may be provided, each having a lip formed along its upper edge to be received in a chased groove in the brickwork of the wall.
  • the upper edge of the flashing may be anchored to the wall by a render or suitable adhesive applied thereover to provide a seal.
  • Insulation is often added to buildings to conserve energy by preventing heat loss through floors, walls, ceilings and lofts. With ever increasing fuel and energy costs there is a continuous drive to improve the thermal efficiency of both old and new build buildings.
  • a weatherproof render or other substantially weatherproof layer may be applied to or may be provided on an outer face of at least one side of the panel, preferably the side forming an exposed face of the panel.
  • Insulation by such external panelling is especially done in the field of modernising buildings.
  • This solution leads to excellent heat insulation with a non-destructive intervention, which is relatively rapid and economically advantageous.
  • installation is done outside of the building and therefore does not interfere with normal activities inside the building and does not reduce the internal area of the building, unlike panelling applied to the interior walls.
  • a flashing construction for forming a weatherproof seal at the junction of a wall and a roof comprising a first layer formed from a sheet of deformable weatherproof material, and a second layer formed from a thermally insulating material, said first layer defining an outer layer of the flashing construction and at least a portion of said first layer being bonded to the second layer, wherein said first layer extends beyond said second layer at an upper edge thereof to enable said first layer to be anchored to a wall.
  • At least a portion of said first layer, preferably adjacent a lower edge thereof, is not bonded to said second layer to enable a further sheet of deformable weatherproof material to be inserted between said first and second layers.
  • said further sheet of deformable weatherproof material comprises an apron adapted, in use, to be located over the top edge of a roof where it abuts an upstanding wall.
  • Said second layer may extend below the lower edge of said first layer, such that a lower edge of said second layer may be cut or otherwise shaped to conform to the shape of an adjacent roof covering (e.g. tiles).
  • an adjacent roof covering e.g. tiles
  • said second layer is formed from a sheet of thermally insulating material having a thickness greater than that of the first layer.
  • said insulating material defining said second layer comprises one of Aerogel, PIR (polyisocyanurate) or phenolic resin.
  • a method of forming a weatherproof seal at the junction of a wall and a roof wherein composite insulated panels are applied to said wall comprising the steps of providing a flashing construction comprising a first layer formed from a sheet of deformable waterproof material, and a second layer formed from a thermally insulating material, at least a portion of said first layer being bonded to the second layer, wherein said first layer extends beyond said second layer along an upper edge of said second layer, applying the flashing construction to the wall adjacent the junction of the wall with the roof, and chasing in or otherwise fixing the upper edge of the first layer to the wall.
  • the method may comprise the further step of shaping a lower edge of the second layer to conform to the shape of a profiled roof covering against which it is applied.
  • the method may comprise the further step of applying an apron flashing to the roof covering adjacent the wall, an upper end of the apron flashing being returned up under the first layer to be located between the first layer and the second layer to form a weatherproof seal therebetween.
  • Figures 1 and 2 illustrate a building having a pitched tiled roof 2 abutting a wall 4. Sections of insulated flashing 10 constructed in accordance with an embodiment of the present invention are applied to the junction between the roof 2 and the wall 4.
  • Each section of insulated flashing 10 comprises a sheet of thermally insulating material 12, formed from Aerogel, PIR (polyisocyanurate) or phenolic resin, to which is bonded a sheet of deformable weatherproof material (flashing) 14, for example a lead sheet or any suitable natural or synthetic material as is known in the art, to define an outer surface of the flashing construction 10.
  • a sheet of thermally insulating material 12 formed from Aerogel, PIR (polyisocyanurate) or phenolic resin
  • flashing deformable weatherproof material
  • the weatherproof flashing material 14 is bonded to an upper edge of the sheet of thermally insulating material 12 and to a front face of the sheet of thermally insulating material 12 over approximately an upper half or upper third A of the sheet 12.
  • a lower region B of the deformable weatherproof flashing material 14 remains unbonded to the insulating material 12 so that a further layer of material, such as apron flashing 6 or soakers, can be returned up under the deformable weatherproof material to be located between the flashing material 14 and the insulating material 12 to form a weatherproof seal therebetween.
  • An upper edge 16 of the flashing material 14 extends beyond the insulating material 12 so that it can be received in a chased groove 8 in the brickwork of the wall 4 or can be anchored and sealed to the wall 4 by suitable adhesive to form a watertight seal against the wall 4.
  • the lower portion 15 of the sheet of thermally insulating material 12 may extend beyond the lower edge of the flashing material 14. Such lower portion 15 may be cut to conform to the shape of profiled tiles or other profiled roof coverings so enable the sheet of thermally insulating material 12 to form a close fit against the profiled roof covering to prevent thermal bridging. Where the flashing is intended to be used with a flat roof, the bottom edge of the flashing material 14 may terminate flush with the bottom edge of the insulating material 12.
  • Figure 4 illustrates the insulated flashing constructed in accordance with the present invention in use to form a weatherproof seal at the junction of a flat roof 2B and a wall 4. Again, a further sheet of flashing material (apron) 6 is returned up under the flashing material 14 to be located between the flashing material 14 and the sheet of thermally insulating material 12.
  • apron flashing material
  • FIG. 5 illustrates the flashing construction in use with composite insulated panels 22 applied to the exterior walls of a building.
  • the flashing construction 10 would be fitted to the wall 4 adjacent the roof 2B, the upper edge 16 of the flashing material 14 being chased in or sealed against the wall with a silicon "Lead sealant", before a base rail 20 is fitted to the wall, prior to installing insulated panels.
  • the base rail 20 overlaps the flashing material 14 so as to form a weather tight seal behind the insulation.
  • An apron flashing or soaker 6 may be returned up under the flashing material 14 to be located between the flashing material 14 and the insulating material 12 to form a weatherproof seal therebetween.
  • the thickness of the insulated material 12 may be selected to suit the thickness of the insulating panels 22 being used and to alter the projection of the flashing.
  • insulated flashing constructed in accordance with the invention may be installed over existing lead on bay windows or porch roofs as an insulated roof covering indistinguishable from the original. As is best practice, no section of flashing would be supplied more than 1500mm long.
