These include smaller-sized timber, and longer spans.

Rent to Own Homes Tulsa Zillow. So the Scissor Truss tends to be one of the more expensive trusses we work with at VTW.

By taking this approach, we eliminated dozens of similar home-performance headaches.

Vermont Timber Works custom designs and fabricates beautiful timber frame homes, post and beam barns, heavy timber churches, cathedral ceilings and more.

They sheathed the underside of the truss with an OSB air barrier, sealed with 3M 8067 tape.

We would have to figure out how to insulate and air-seal that wall—and in a typical house built by a typical production builder, that whole wall would show up as a cold spot in thermal scans. Truss framing is quicker and simpler than rafter framing, and it offers better energy efficiency too: You don’t have to run vent channel up the whole length of each bay, you can pile deep blown insulation above the ceiling, and you don’t have a thermal bridge from the ceiling to the roof as you would in a full rafter-framed cathedral.But scissors trusses have drawbacks in terms of home performance.

The house was to be a one-story, three-bedroom, two-bath house built on a slab foundation, and the slab was also going to be the finish floor.

Their appearance is lighter than timber, so opting for steel chords can make a space feel more open.It’s good to have options for consideration.

We are not automated, so we have the flexibility to create structures to our clients exacting details.Vermont Timber Works custom designs and fabricates beautiful timber frame homes, post and beam barns, heavy timber churches, cathedral ceilings and more. With a few thoughtful modifications, a scissors-truss roof system can contribute to outstanding energy efficiency.In this story, I’ll show some tricks for squeezing better performance out of conventional old-school scissors-truss roofs. Then the ceilings were furred down. Solid Beams: Which Is Best For Your Project?Above, is a rustic open pavilion frame that has Scissor Trusses reinforced with steel joinery plates (for people who do like the look of steel).Below, is a Scissor Truss engineered for a great room.

The photos on the following pages come from an advanced custom home project we helped to build a few years ago, but the ideas originally evolved as we worked on the proposal for a similar high-performance Habitat for Humanity project at around the same time. Joinery can be detailed in the isometric drawing as well.

The author’s crews use a custom baffle made of one-inch rigid foam to help contain dense-packed insulation.After attaching OSB to the underside of the scissors trusses and sealing the seams with tape, the author’s crew foamed the gaps in the gable end wall to contain blown insulation.Intello smart vapor retarder fabric was wrapped up the gable wall.A horizontal strip of OSB at wall-plate height tied the inner wall frame to the outer frame.For a practical, high-performance solution, the author’s company devised a raised-heel scissors truss that’s detailed to work well with a double studwall configuration.

Then we designed our trusses with a high heel above the wall plate and with a horizontal shelf projecting inward from the outer loadbearing studwall that could catch the top plate of the inner studwall.

Then I’ll take a look at the improved version of a scissors truss that our company has used to build exemplary high-performance homes. You not only get the speed of framing that you get with common trusses but also the added benefits of an interior sloped ceiling. If we ran the scissors trusses along the whole length of the house, we could construct the air barrier with OSB on the underside of the trusses.

Scissors trusses can be an example of that problem—but they don’t have to be.
