As bi-folding doors and larger openings continue to be specified in modern conservatories and glazed extensions, Prefix Systems have launched Bi-span, the industry’s first universal support kit. This has been engineered for the vast majority of conservatory roof systems, including Eurocell, Synseal, Ultraframe and Wendland.
The first generation eaves beams in conservatories were not designed to cater for such applications and the newer beefed up sections add significant extra cost in areas that don’t need additional structural support. The Bi-span support kit is used only in the areas where it’s needed and can be integrated into new installations or indeed Retro-fitted into existing ones. Thanks to a clever design the kits can be seamlessly integrated into installations with no loss of height.
The Bi-span support kits have been specifically designed to reduce bounce and deflection. Each kit comprises of a horizontal support beam which is fixed onto the eaves beam during roof fabrication and is supported either side of the opening with aluminium support posts. These fix to the support beam with a 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 the necessary connecting brackets.
Feedback from existing customers has been overwhelmingly impressive and it has proven to be a simple to install and complete solution for large openings. The kits are available in a wide range of colours including 2 shades of white, whitegrain, golden oak, irish oak, rosewood, fir green, chartwell green, black and grey. Alternatively, there’s the option of a bespoke colour through the new painting facility at Prefix’s head office.
Bi-span is perfectly suited for bi-folding door openings and can be run across one side of the conservatory or the front face. A typical kit provides reduced sightlines, offer identical returns for more uniform aesthetics and eliminates the need for any window frame add-ons. Importantly, it’s also the most cost effective support solution available.
