To be read with the Preliminaries/General conditions[ A10-A55 and A90]


Thermal Break Flashing Profile below Eaves, behind Rainwater Gutter & above EWI
275E    THERMAL BREAK FLASHING PROFILE BELOW EAVES, BEHIND RAINWATER GUTTER & ABOVE EWI

  • Drawing Reference(s): [________]
  • Constructive Details Ltd.:
  • CD0109 Thermo-Pro Fascia
  • Reference Documents:
  •             Constructive Details Ltd.:
  •             A handbook of thermal bridging details incorporating Instaclad insulated themal profile solutions
  • Book 8 — Cold bridging solutions for insulating on retrofit External Wall Insulation
  • Purpose: The Thermo-Pro range of profiles has been developed to provide a weather tight and thermal bridging breaking solution for external wall insulation systems around eaves abutments and services.
  • Applications:
  • Abutments with removable and relocatable refixable rainwater gutters and downpipes, etc.
  • Used to insulate up to the roof level behind the gutter, above EWI, when there is no soffit on the property.
  • Preparation:
  • Temporarily remove existing guttering will have to be removed temporarily to allow insulated flashing to be installed,
  • If however the guttering is in poor condition we would recommend that the replace guttering is replaced to protect the long-term performance of the insulation upgrade.
  • Thermal Conductivity Insulation:
  • Vapour Control Layer Foil wrapped Insulation
  • Insulation Material: Aerogel
  • Product Reference: Spaceloft Aerogel
  • Manufacturer: Aspen Aerogels Inc. USA
  • Thickness: 10 mm
  • Bonded to back of metal profiles
  • Profiles: pressed/extruded interlocking profiles
  • Metal: Aluminium

  • Gloss level: [________] %
  • Product Reference: Thermo-Pro® Fascia
  • European Patent No. 2703574
  • Fasteners: assuming brickwork and lime mortar
  • Material: [________]
  • Type: [________]
  • Size: [________]

276E    THERMAL BREAK FLASHING PROFILES BEHIND RW DOWNPIPE SWAN NECK CUTTING INTO EWI

  • Drawing Reference(s): [________]
  • Constructive Details Ltd.:
  • CD0058 Thermo-Pro Soil Pipe
  • CD0109 Thermo-Pro Fascia
  • Reference Documents:
  •             Constructive Details Ltd.:
  •             A handbook of thermal bridging details incorporating Instaclad insulated thermal profile solutions
  • Book 6 — Thermo-Pro Soil Pipe solution for insulating on retrofit External Wall Insulation
  • Book 8 — Cold bridging solutions for insulating on retrofit External Wall Insulation
  • Purpose: The Thermo-Pro range of profiles has been developed to provide a weather tight and thermal bridging breaking solution for external wall insulation systems around eaves abutments and realigned services.
  • Applications:
  • Abutments with removable reclaimable and realigned rainwater downpipes, etc.
  • Allows the thicker EWI insulation to be installed as high up the wall as possible by allowing the slim swan-neck piece of the gutter to cut into the EWI system.
  • The gutter box can also be used at the bottom of the wall to allow the downpipe to drain into the original gully or drain and avoid or prevent overspill during heavy rain.
  • Preparation: remove and reclaim existing rainwater downpipes for reuse
  • Thermal Conductivity Insulation:
  • Vapour Control Layer Foil wrapped Insulation
  • Insulation Material: Aerogel
  • Product Reference: Spaceloft Aerogel
  • Manufacturer: Aspen Aerogels Inc. USA
  • Thickness: 10 mm
  • Insulation VCL Bonded to back of metal profiles
  • Profiles: pressed/extruded interlocking profiles
  • Metal: Aluminium
  • Finish: Powder coated to work section Z31
  • Colour: [______], RAL/BS 4800: [________].
  • Gloss level: [________] %
  • Product Reference: Thermo-Pro® Rainwater Gutter Box
  • Model Reference: [TPGT/TPGB]
  • Application: [Top/Bottom]
  • Size: one size
  • European Patent No. 2703574
  • Fasteners: assuming brickwork and lime mortar
  • Material: [________]
  • Type: [________]
  • Size: [________]
  • Spacing: [________]
  • Completion:
  • [Modify and refix reclaimed or fix new] rainwater downpipes, realigning to fix to face of EWI
  • Coordinate with rainwater gutter outlets, fascia cutout boxes and base cutouts boxes
