WarmCore aluminium  folding doors  were created out of a desire to combine the desirability and durability of aluminium with unparallelled insulation.
 25% more thermally efficient than traditional aluminium bi-folding door systems 

Strong Construction Built for unparallelled Security

From the unique 5 point lock, designed to run the full length of the door sash, to the high strength hinges and rollers; each element of the WarmCore door combines to ensure optimum security.

WarmCore’s aluminium construction, custom-made roller assemblies - sitting deep within the top and bottom tracks - and extruded aluminium hinges make them inherently strong and secure. Added security features such as integral dog bolts bind the door sashes together when closed, protecting against forced entry.

A custom designed door lock, available on no other door system, uses a 5 point locking system with 3 opposed hook locks and twin shoot bolts - that engage fully into the aluminium top and bottom tracks - helping keep you and your family safe and secure. For added peace of mind choose the optional laminate glass upgrade – giving WarmCore doors Secured by Design accreditation - the official UK Police initiative ‘designing out crime’ through physical security.

Every WarmCore door is independently certified to PAS24:2012, the benchmark in enhanced security performance requirements for doorsets and windows in the UK.

  • PAS24 and Secure By Design (SBD) compatibility as standard provides peace of mind for end users. WarmCore doors have been independently third party tested by a UKAS laboratory to prove impressive structural strength and security credentials
  • Double-strength sash corners are mechanically jointed and use a combination of internal aluminium cleats and a wrap-around corner moulding block to ensure secure rigidity and robustness in use
  • Custom-engineered extruded aluminium hinges are designed with security in mind
  • Hinges clip-fit for ease of on-site installation
  • Integral dog-bolt feature for high security
  • Multiple screw fixings are sited at the knuckle and in the main body
  • Run-through gasket grooves allow for continuous weather-seals
  • Robustly designed to take the weight of triple glazed units as standard
  • Custom-designed sash corner blocks cater for plain corner, shoot bolt, roller casting and pivot hinge applications and these hardware components ensure high quality installation and operational performance
  • Added reassurance for both installers and homeowners is delivered by our custom-designed hardware development partners who underwrite and provide an ERA “Five-Star” security guarantee against forced entry for a period of 10 years.
