Pitched Roof System HH – Hybrid System


Actis has developed solutions for warm pitched roof structures which use a combination of insulation between and across timber rafters, which help to create highly insulated, airtight buildings that will meet the most onerous energy performance requirements.

The pitched roof system HH uses Hybris insulation installed between timber rafters and HControl Hybrid installed internally across the face of timber rafters as follows:

  • Tiles
  • Tile battens / counter battens
  • Breather membrane
  • Air cavity
  • Hybris reflective insulation
  • Air cavity
  • HControl Hybrid multifoil blanket insulation
  • Air cavity
  • Plasterboard

Hybrid products combine airtightness and vapour control properties with insulation and therefore offer a complete solution against heat loss through the building fabric: low U-values, minimised thermal bridging and excellent airtightness.
