Insulate Roof Trusses

Why should you insulate exposed roof trusses the finish ceiling option.

Insulate roof trusses.

The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow. Like ordinary roof trusses scissors trusses come with or without a raised heel sometimes called an energy heel. For the same reason insulation shouldn t touch the roof s underside. In a warm roof structure the insulation is placed above or above and between rafters in order to avoid heat loss and energy transfer.

This is because the effects of thermal bridging are limited which also results in the elimination of melt lines on the roof surface in cold climates. Encapsulating the rafter or top truss chord roof framing members with spray foam will improve the energy efficiency of the attic space. Isoboard thermal insulation fitted as a ceiling following the roofline allowing the opportunity to create additional space or a liveable loft conversion. A variety of insulation materials can be used to insulate scissors truss roofs as long as.

Staple plastic or foam baffles to the roof sheathing near the eaves to keep the material away. Place the plastic sheeting on top of the rolled insulation. Using panelized roof sections. For rolled insulation place it between roof rafters.

Following ten years of extensive testing isoboard thermal insulation has developed a proven solution to fixing its thermal insulation boards above rafters trusses or beams. If you want to keep your exposed roof trusses visible then the easiest way to add some. In the case of a cold roof structure the insulation is placed between or between and under the rafters or at ceiling joist level and the roof is ventilated by leaving a 50mm gap above the insulation which vents air to the outside. Then feed the rolled insulation under wires and pipe if either is present.
