Definitions

  • This invention relates to a sealing adaptor for use in installing windows in an external surface of a building.
  • Velux-type windows can be used above a roof pitch of 22 degrees. These low profile Velux windows can be fitted on a roof with a suitable covering material having a roof pitch between 15 degrees and 90 degrees.
  • a low profile window for example a low profile Velux roof window can only be installed retrospectively on a loose laid tiled roof.
  • Low profile Velux windows lend themselves to low pitch roofing where standing seam zinc or copper or stainless steel sheet material is used because the metal flashings (which can be colour coordinated to suit the roof covering) are in-keeping with a metal roof.
  • low profile Velux-type roof windows may be prone to leakage when installed at a pitch of less than 15 degrees.
  • roof windows in low-pitched roofs (typically having a roof pitch below 15 degrees) by incorporating an upstand into the roof to allow the roof window to be mounted at an angle of at least 15 degrees to the ground, even though the pitch of the roof is less than 15 degrees.
  • an upstand into the roof to allow the roof window to be mounted at an angle of at least 15 degrees to the ground, even though the pitch of the roof is less than 15 degrees.
  • such an approach may look unsightly, and/or block out some of the light which would otherwise enter into the building through the roof light were the roof light mounted substantially flush to the rest of the roof.
  • the low profile Velux window typically has an inherent up-stand of approximately 80mm when installed. This up-stand can be problematic when using standing seam roofing. In the case of zinc, copper and stainless steel roofing sheets, gussets must be soldered at each corner, which can be complex in this situation. Furthermore, the standing seams are typically 25mm in height and the window is 80mm high. Therefore, the seams must be staggered around the up-stand of the low profile Velux window and the seam that will finish behind the up-stand is cut out, hammered down flat and soldered. Though note that aluminium and zinc coated aluminium cannot be soldered, which means an alternative solution must be found for these materials.
  • One current way to use the low profile Velux windows with zinc standing seam roofs is to tuck up the sheet roofing material under the metal flashing provided as part of the installation kit for the low profile window. This allows for installation of the window, but does not solve the problems caused by windows which project too far from the roof, and still may not provide a sealed window in a low-pitch roof. Furthermore, care must be taken when positioning these windows as they have no allowance for thermal movement in the sheet roofing material due to thermal expansion and/or contraction as a result of temperature changes of the roof.
  • Another type of roof window or non opening roof light for low pitch roofs is a fixed deadlight which is typically mounted on a kerb or up-stand of approximately 200mm which is usually formed from powder coated aluminium. Again, this solution does not solve the problems caused by windows which project from the surface of the roof.
