Slide Folding Doors.
High Performance Thermally Enhanced Bi-Folding Door
Metal Technology's thermal range of Bi-Folding doors are the perfect
solution to open up your home and bring the outside in, while
keeping the elements out. Our Bi-Fold doors offer a wide range of
designs from two to seven panes and up to 6 metres in width giving
architects, clients and specifiers total design flexibility. The
door can also be used in a single door application. Door sashes can
accommodate either open in or open out applications, with an option
of either curved or flush profile door leaves or fully rebated or
low thresholds.
Thermal Performance
Metal Technology's Bi-Fold doors offer exceptionally low U values
using bespoke polyamide thermal isolators designed to minimize heat
transfer across the door profiles. This can be further enhanced with
a high insulation (Hi+) option of uniquely designed cellular foams
which enclose internal cavities within the profile, further reducing
heat loss and providing one of the most thermally efficient systems
available.
* Door U values based on 3000 x 2200m three pane Bi-fold using warm
edge swiss spacer V bars and fully rebated thresholds.
Metal Technology can provide tailored U-value calculations using
their dedicated estimating software to calculate overall project
average door U-values for their full range of systems.
Construction
Frame and door sash members are mitre cut at 45 degree. Corners are
reinforced with extruded aluminium crimping cleats and corner
braces. A secure joint is formed by pneumatically crimping into the
extruded crimping cleat. Mullion and transom bars are square cut,
shaped and fixed securely to the frame by means of stainless steel
screws and fixing cleats. All frame joints are sealed during
construction against entry of water using Metal Technology's two
part adhesive. Metal Technology recommend that only A2 or A4
austenitic (300 series/class 70) stainless steel fixing screws are
used in the assembly of their products.
Glazing
This system offers internally glazed sashes and can accommodate
glazing units from 28mm to 50mm units.
