Airtightness and Clause H1: Getting the Full R-Value Out of the Insulation

Insulation only performs to its R-value when the air around it stays still. Here's how INTELLO PLUS makes airtightness count in your H1 calculations while keeping moisture out of the structure.

Above Sheathing Ventilation – Part 1: Rise of the Cavity

Above-sheathing ventilation (ASV) uses solar energy to induce airflow between the cladding and the membrane by heating the roof cladding and warming the air in the cavity below.
