In response to the increased demand for larger openings in conservatories Prefix Systems have introduced the Bi-span support kit to cater for additional loadings as a result of more flamboyant conservatory designs.
Simply put -The first generation eaves beams were not designed to cater for large openings, yet the more recently developed heavy duty sections add additional cost in areas of the conservatory that don’t need the extra structural stability. Bi-span is used where it’s most needed on conservatories and can be integrated within new installations or on existing ones, to reduce bounce and deflection – it can perform a number of tasks.
Bi-span kit comprises of a horizontal support beam which is fixed into the eaves beam during roof fabrication, prior to despatch (or into the existing eaves on site if used as part of a refurbishment project), the beam is supported either side of the opening with Aluminium support posts which fix to the support beam with purpose designed ‘L’ section bracket and into the face of the door / window profile. A load bearing spreader plate is also supplied for the foot of the posts along with brackets to connect – A simple to install complete solution.
Bi-span is perfectly suited for bi-folding door openings and can be run across one side of the conservatory. It has reduced sightlines, provides identical returns for more uniform aesthetics and eliminates the need for any window frame add-ons – it is the most ‘cost effective’ support solution available.
