Warm roof construction utilising Masonite, is able to provide complete usage of the roof void and thus more value from the footprint of the dwelling.

Construction Examples:
Pre-Insulated Roof cassettes and A-Frames have been used to create valuable storage or habitation space.
- Beacon Edge. An example of a traditional block and stone garage with a Masonite roof providing u-values in excess of 0.16. This provides an easily heated workspace during the winter months.
- Beacon Edge. Eaves extensions using plywood inserts to the Masonite web, 100 x 50 spar ends attached to the Masonite. Note the panelvent barrier to contain the Warmcel insulation to the outside of the timber frame ensuring a complete envelope of insulation.
- Beacon Edge. Masonite Portal Frames or trusses to construct the roof. A mid-way between stick build and pre-fabrication.
- Becklands. Converting an existing bungalow into a house with first floor accommodation. A stick built project forming a roof over the existing roof to maintain protection from the elements during construction.
- Becklands roof over roof.
- Becklands roof over roof.
- Prickwillow. Securing the gable panels and linking to the dwarf walls. Note the 11m Glulam ridge beam.
- Prickwillow. Construction of roof panels in the factory. Apertures are formed for velux windows Note the plywood inserts to the Masonite web, birds mouth to fit the wall plate and additional lifting stability timber. The 4” hole in the aperture is to allow Warmcel insulation to be injected to fill the panels under pressure.
- Prickwillow. Glulam Ridge beam connecting gable panels and internal gable panels.
- Prickwillow. Ridge Detail.
- Prickwillow. Fixing opposite roof cassettes.
- Prickwillow. Eaves detail. Note the triangular wall plate to locate the roof panels.
- Prickwillow. Masonite ridge cassette connectors.
- Shipley. Ridge and A-Frame construction to the roof.
- Shipley. Eaves detail showing roof cassette sitting on first floor cassette. Note triangular wall plate and double birds mouth to assist in panel restraint and the plywood stiffeners fixed to the web of the Masonite beam. These beams were 400mm deep.
- Shipley. Roof panels located between the A-Frames. Note the openings at the eaves and ridge to allow mechanical fixing between elements. These will be boarded and insulated on site.
- Hall Hill. A stick built roof utilising the 11m lengths of Masonite and high levels of insulation. Steel purlins and flitch-plates were utilised in this roof construction. Note the spar ends being added on site.
- Hall Hill. Noggins on site are time consuming and awkward to fit requiring endless amounts of internal scaffold for access. Pretty cold too, and cost savings over factory built are questionable.
