Covers designing compliant roof and loft insulation under PAS 2035:2023, managing cold roof moisture risks, thermal bridging and ventilation requirements.
This technical course provides a comprehensive guide to designing and managing compliant roof and loft insulation projects under PAS 2035:2023. It equips Coordinators with the knowledge to identify "hidden" cold roof risks, manage critical junctions to prevent thermal bridging, and balance conflicting requirements for fire safety (Part B), ventilation (Part F), and thermal performance (Part L).
Cold Roof vs. Warm Roof, Sloped Ceilings, Thermal Bridging, AVCL (Air and Vapour Control Layer), Interstitial Condensation, Ventilation Strategy, Approved Documents L/B/F, Pre-Installation Inspection, Handover.
This lesson covers the governance of roof retrofit. You will learn to integrate thermal targets with mandatory ventilation and fire safety rules. Crucially, it explains the moisture risks in "Cold Roofs" and "Warm Roofs," teaching you to identify when a 50mm continuous air gap is mandatory to prevent structural rot.
Here, the focus shifts to the physical specification. You will learn to evaluate materials based on the "trade-off triangle" of thickness, breathability, and fire safety. The module details how to enforce the "Principle of Continuity" at critical junctions (like eaves and reveals) to eliminate thermal bridges and cold spots.
The final lesson covers the practical management of the installation. You will learn the specific pre-installation checks required for safety (e.g., electrical cables, water tanks) and the mandatory "hold points" for inspections. It concludes with the requirements for a compliant handover, ensuring residents understand how to operate their home's new thermal balance.
