Defender ModuleX

A highly durable and secure doorset, that’s the ideal solution for modular buildings such as classrooms, meeting rooms, short-term accommodation and much more.


DDA Compliant

The Defender ModuleX doorset has been designed for the modular building industry to provide an ultimate fast-fitting and cost-effective solution complete with a four-sided cloaking frame.

The Defender ModuleX doorset is manufactured from 1.5mm galvanised steel and internal steel strengthening as standard. Frames are 1.5mm galvanised steel and have 1.5mm stainless steel thresholds making the Defender ModuleX a longer lasting, stronger door. The mineral wool core is also more thermally efficient than cardboard honeycomb infill versions.

The unique flange frame design efficiently seals the frame to the building whilst concealing panel cut outs.

Door Leaf

Manufactured from two 1.5mm Galvanised steel skins, folded and mechanically fixed to form a strong and rigid 45mm thick door leaf, filled with internal steel strengtheners and mineral wool for ultimate insulation. Anti-jemmy flanges to the leading edge of the leaf provide excellent jemmy resistance.


90mm frames are pressed from 1.5mm galvanised steel to form a single rebated and an in-built cloaking profile. Profile headers form a smooth butt joint with the vertical posts and are joined together utilising strong M8 bolts to provide positive rigidity. The special fast fit frame is able to compensate for most irregularities in the opening with 16no threaded fixing adjusters per doorset. They permit a tolerance of up to 18mm on each side of the door. Shims and packers are not necessary making an extremely secure fix. Alternative frame depths are available on request to suit your specific wall panel construction.


Door leaves are hung from 4no stainless steel hinges for smooth operation and optimum weather resistance. Security dog bolts secure the leaf into the frame if the hinges are attacked. Additional hardware includes a range of locks, latches, lever handles, panic hardware, closers and door restrictors. On double doors, lever-action flush bolts can be installed within the leading edge of the inactive door leaf.


Available in any standard RAL powder-coat finishes.


DDA compliant 1.5mm stainless steel threshold bolted into the vertical frame posts. Available in inward or outward opening with full in-built cloaking to prevent water ingress into the floor of the building.

Thermal Performance

Tested and achieving a rating of 2.2W/m2K based on a door size of 1090mm x 2090mm WxH – values may vary slightly depending on size and finished colour of doorset.

As per third party accreditation testing by Ceribois (notified body number 2061) to European Standards EN 1007-1 and EN 13126 on 23rd March 2016.


For optimum weather, thermal and acoustic performance, a tubular silicone/rubber is bonded into the frame rebate to ensure effective sealing of the door/frame gap.

Optional Extras

A full range of vision panels are available in various glass types and thicknesses. Louvre panels, closers and door restrictors and emergency exit panic ironmongery are available.
