Insulating Shed Roof Trusses

A roof is like a hat.

Insulating shed roof trusses. The minimum rating of r38 in a roof requires some creative planning in the roof design of a new shed with 2 x6 minimum roof construction. Care is needed to ensure that there is sufficient ventilation space between the underside of the roof deck and the top of the insulation. In areas with a cold climate part of the year r38 is the minimum and r50 is recommended. These foam pieces are as wide as the rafter spacing and form a channel for air to flow between the top of the insulation and the roof sheathing.

The gable shed has a roof like a house so the roof trusses will have a peak in the middle. Each roof style has some different insulating challenges. The truss sides will be equal in length and width to fit equally on the shed walls. Insulating a shed roof is typically done using insulation below the roof deck and between the rafters.

Cut batt or blanket insulation that has an attached vapor barrier an r 20 or greater value and a thickness of about 6 inches to fit the spaces between roof trusses inside the shed. In addition to the lean to shed there is a gable shed roof. For a heated shed warmer air inside rises and can have a relatively high moisture content. Such roofs lack maintenance as well.

Keep in mind also that the longest lasting shed roofs are usually made of such metals as aluminum steel or copper. You can insulate your shed roof to enhance more energy savings but make sure that you insulate the roof properly. Because of limited space between the roof sheathing and ceiling joists a low slope shed roof can be difficult to insulate properly. It keeps everything under it warm.
