EWP Roof Applications

All of our EWP products free your architect and your imagination to create unusual features such as curved ceilings and exposed beams.

EWP systems can act as free-spanning rafters between a ridge beam at the roof apex and the wallplate at eaves level to create open roof voids or to create.  And Metal-Web joists offer an alternative to attic trusses to create a completely open and vaulted ceiling without any need for ridge beams.

EWP Floor Applications

The performance of a floor is matter of opinion.  The “feel” that satisfies one individual may not satisfy another.  Many factors affect the perceived performance of a floor. They include:
Joist depth and spacing:  the stiffness of a floor can be markedly improved by increasing joist depth, for example, a 25% increase in joist depth will double the floor stiffness.  While floor stiffness increases in inverse proportion to space between joists.
Continuous or simple spans: Allowing joists to span over, rather than breaking at, internal load-bearing walls can increase floor stiffness by up to 240%.
Decking / flooring material:  Thicker decking slightly improves floor performance for example 22mm chipboard increases floor stiffness by approximately 2% compared to 18mm chipboard and means less ‘local’  deflection under foot.
Fixing of decking material:   Gluing your floor deck to your joists can improves floor stiffness by as much as 70%.
Ceiling material:  Directly applied ceiling boards below the joist can improve floor performance by up to 3%.
Level bearings:  Unlevel bearings can mean joists feel "springy" under foot near bearing positions.
Location of walls and furniture:  the position and size of dead loads on floors can either dampen or exaggerate the dynamic response of floors under foot.
