Under Roof Trusses

Building owners often times would like to eliminate the extra space above the roof trusses for heating and cooling purposes, or to simply give the building a flat ceiling.  A common method for doing this is to insulate to the underside of the trusses.  Fiberglass insulation blankets are cut to fit in between the trusses and are held in place by steel banding.  The steel banding is installed or screwed to the bottom face of the trusses.  The insulation blankets sit on top of the banding.  Whether the wood trusses are covered or not is dependent on the owner and the look that is to be achieved.  It is important to ventilate above the fiberglass blankets, similar to a home attic.  This will help to prevent condensation.BottomTrusses
