Benefits of timber frames and trusses

The truss is a construction invention that enables the roof weight to be evenly distributed to the exterior walls for enhanced support. A truss is usually triangularly shaped or composed of many triangles. This shape provides the building better support and enables the builder to use lesser materials to achieve the same result.

Quick Installation

The first advantage of a timber frames and trusses is that it can be installed cost-effectively and quickly, even without using heavy equipment to place it. Many of timber frames and trusses are factory built and can be delivered to the site as one structure set. The truss is conventionally leveraged on top of the wall. It is then slid into position before being pivoted upright and fastened in place. 

Increased Span

Another unique property of a triangular object is that it allows trusses to span across wider distances. A roof with square sides tend to twist and shift, a triangular roof maintains shape, prevents sag and shift. As an added benefit, the entire truss set combination becomes stable and is more able to support multiple times the weight  when compared to a non-reinforced straight roof.

Load Distribution

The triangular shape allows the whole weight applied to the legs (sides) to be redistributed away and down from the center. In trusses, this transfers the complete roof weight to the exterior walls, and has the benefit of allowing the inside walls to be built promptly, or even omitted or moved.

Accessibility

As the bottom truss rail is usually the ceiling of the rooms right below, the truss’s triangular spaces themselves form reachable paths for the installation of electric, HVAC, and other types of utility applications. The truss’s central void system is generally the home’s attic, with the roof slope forming the triangle legs.
