June 2025 – New Details

We’re excited to announce a fresh set of technical details focused on skylights and flat roof assemblies in house extensions — designed to help you integrate daylight, performance, and aesthetic flexibility into your projects. This month’s upload features a suite of rooflight configurations from Roofglaze, along with carefully coordinated flat roof junctions, including options for walk-on rooflights and green roofs.

Highlights from this set include:

• Flat Roof to Existing Wall Abutment
  A flexible detail showing options for steel support at the junction of new flat roofs and existing walls—ideal for retrofit scenarios requiring fire-rated construction and clean ceiling transitions.
• Fixed Skylights in Flat Roofs
  Multiple variations of fixed skylights, including hidden or visible frame options. These details are designed for thermal performance and adaptability across roof finishes.
• Walk-On Skylights
  Designed for terraces and roof gardens, these walk-on options integrate units with either paved or green roof finishes. They include considerations for drainage, substrate build-up, and accessibility.
• Sliding Rooflights
  A detail showing a mechanically operated sliding skylight, perfect for spaces where ventilation, roof access, or dramatic daylighting is needed.
• Low Embodied Carbon Skylight Roof
  A sustainable flat roof detail using wood fibre insulation, paired with skylights—ideal for projects targeting reduced environmental impact.

All rooflight details are designed with performance and buildability in mind, and each includes guidance on thermal bridging, airtightness, and compatibility with standard roofing systems. As always, we recommend consulting with structural engineers and manufacturers for project-specific design coordination.
