Insulate Roof Trusses

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

Insulate roof trusses.

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. Using panelized roof sections. Isoboard thermal insulation fitted as a ceiling following the roofline allowing the opportunity to create additional space or a liveable loft conversion. Encapsulating the rafter or top truss chord roof framing members with spray foam will improve the energy efficiency of the attic space.

Like ordinary roof trusses scissors trusses come with or without a raised heel sometimes called an energy heel. Place the plastic sheeting on top of the rolled insulation. The right way to insulate attics and cathedral ceilings with batts using certain t. If you want to keep your exposed roof trusses visible then the easiest way to add some.

Make sure it is flush against the wood as even a 1 inch gap can cause a 20 percent heating loss. Then feed the rolled insulation under wires and pipe if either is present. For the same reason insulation shouldn t touch the roof s underside. For rolled insulation place it between roof rafters.

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. Staple plastic or foam baffles to the roof sheathing near the eaves to keep the material away. 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. The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow.
