The Attic Truss

The Attic Roof Truss is a design that provides a central open space that can be used to accommodate a living space or alternatively a storage space. The timber webbing configuration is engineered above and on either side of this central open space. The attic truss design enables roof loads to be transferred down to the wallplate. Insulation is fitted by MBC running up the slope of the attic roof truss.
