Sectional Doors
TDL Insulated Sectional Overhead Doors give guaranteed high thermal performance, avoiding cold bridging compared with traditional roller shutter
COMPOSITION
The use of quality materials and precise manufacturing controls ensure long service life in normal industrial and commercial applications.
Outer and Inner Sheet
0.5mm hot-dipped galvanised steel. Both inner and outer sheets are supplied “V” grooved to provide increased lateral strength, and the whole panel is made up to form a “T+G” joint top and bottom.
Core
39mm thick rigid polyurethane foam, density 40kg/m3.
Seal
Low-density compressible foam at the panel base, and PVC Tape to the panel nose, all factory applied.
THERMAL PERFORMANCE
Sectional door panels that provide high levels of insulation. The foam core between the inner and outer steel sheets of the door panel creates an effective interruption of cold bridges, thus preventing the transmission of heat or cold.
COLOURS & FINISHES
Outer Skin
The outer skin is finished and coloured to match most contemporary building cladding.
Inner Skin
The internal liner skin is finished in RAL 9010 white, polyester coated, stucco embossed galvanised steel as standard. Colour swatches are available on request.
ACOUSTICS
The 40mm insulated door panel gives a sound reduction of (Rw) 25db. Please note that this is for the panel only, and does not include joints, i.e. a fully installed door.
PANEL OPTIONS & ACCESSORIES
A range of windows in various sizes can be incorporated into the panel, the standard being 600 x 300mm with radiused corners. Each panel is fitted with pre-punched galvanised steel end caps and the top and bottom panels are finished with an aluminium retainer which holds the top and bottom EPDM seals.
A range of locking options are available.
