The MBC Passive Roof system delivers a U-Value of 0.10W/m2K. The Passive Roof & Wall Junction detail shows how the 400mm Cellulose Insulation in the roof is precision fitted to overlap with the 300mm Cellulose Insulation of the Passive Twin Wall System at the eaves juncture. This overlapping arrangement of both the roof and wall insulation, safeguards that the structure is completely wrapped, and free from any thermal breaching.
The MBC Passive Roof System is suitable for all roof designs (flat, pitch, barrel vault, etc), ensuring your building design remains uncompromised. A typical pitched roof sees engineered timber trusses set @ 400mm centres with 25mm x 125mm diagonal bracing and longitudinal binders providing truss stability in accordance with BS 5268 Structural Use of Timber. The truss system utilises the tooth plate systems in which gangnail plates are hydraulically pressed into machine stress graded European whitewood, ensuring structural integrity.
