High performance roofing

Passivhaus

Passivhaus roofing support focuses on careful detailing, insulation, airtightness interfaces and high-performance roof build-ups.

Overview

Practical passivhaus support

Passivhaus projects require particular attention to thermal performance, continuity of insulation, airtightness and junction details.

Roofing works on high-performance buildings need to coordinate closely with the wider envelope so roof finishes, penetrations, upstands and interfaces do not compromise the design intent.

What this includes

  • High-performance roof build-up support
  • Insulation and thermal detailing coordination
  • Careful junctions around edges, penetrations and rooflights
  • Support for airtightness and envelope interfaces
  • Suitable detailing for new build and refurbishment projects

Approach

How the work is handled

  1. Review the project requirements and roof build-up
  2. Coordinate with insulation, airtightness and envelope details
  3. Plan waterproofing around penetrations, outlets and upstands
  4. Install roof finishes with careful attention to continuity and detailing

Important details

What to consider

  • Thermal bridges and air leakage risks should be considered early
  • Roof penetrations and rooflight details need careful coordination
  • The roof system should support the overall performance target for the building
