Thermo Breaking A Metal Roof

The upper layer of fiberglass between the roof sheets and the purlins serve as a thermal break to reduce thermal conduction in addition to the thermal spacer block if applicable in standing seam roofs.

Thermo breaking a metal roof.

However common issues to look out for include discontinuities in the insulation particularly at junctions and around openings. Double layer systems are used in screw down roofs standing seam roofs with or without thermal spacer blocks. In metal and wood framed buildings wrapping a building s envelope with a layer of continuous insulation cuts off thermal bridging. In cold climates the ventilation prevents moisture freezing into damaging ice dams.

A thermal spacer block is placed between the metal roof sheet and the roof purlin or between the wall girt and wall sheeting and isolates the outer shell from the inner steel frame of the metal building. Reduces the flow of thermal energy between conductive materials such as lightweight metal cladding and a steel frame. On the outside face of all external steel wall framing studs plates and dwangs between top plates and bottom truss chords or rafters on the outside edge of the purlins fix a 40 12 mm thick strip of eps.

Unfaced insulation is simply cut to fit the girt spacings and then impaled onto fast r rigid insulation hangers which prevents the insulation from sagging. Thermal break tape helps to establish a vapor seal and acts as a vapor barrier break between the exterior walls and inner framing on metal buildings. In single layer double layer and filled cavity roof insulation systems thermal blocks are placed between the metal roof sheet and the purlins. The simple saver wall insulation system is installed completely from the inside out of the wind and weather.

In warm climates this saves cooling costs by reducing rooftop temperatures. Achieves a material r value of r0 20 to satisfy national construction code ncc thermal break requirements relating to steel framed structures. With its 95 open structure enkaroofvent creates an unbroken air space acting as a thermal break between metal roof panels and sheathing. Placement on top of the purlins is key as this creates a thermal break at the structural members.

Thermal blocks use of the sealed n safe thermal block can easily save a metal building owner thousands if not tens of thousands of dollars in energy and building maintenance costs.
