Reynaers Aluminium has announced that its MasterPatio Bi-Part door has achieved PAS 24 (Performance Assessment Specification - PAS 24:2022).
After undergoing extensive testing to assess the resistance of the doors to forced entry, the MasterPatio bi-parting door configuration is now PAS 24 certified ensuring it can meet enhanced security requirements.
The robust testing behind this certification ensures that it is approved for use in new build projects, demonstrating that the doors can resist a level of attack from opportunist burglars. Now with enhanced security certification, the MasterPatio Bi-Part also offers high performance and design flexibility thanks to its space-saving benefits and a modern, sleek aesthetic.

John McComb, Technical Director at Reynaers Aluminium UK, said: “We understand that modern architecture demands more than a premium appearance - designing for safety, security and sustainability is crucial.
“Through responsible engineering and innovative design, the MasterPatio Bi-Part door system offers slim sightlines and long-term peace of mind thanks to its high-performance security properties and sustainable and efficient production methods.
“The slimline design of the MasterPatio Bi-Part allows architects to specify a four-pane door in a shallow wall structure, where a standard sliding door would not normally fit. With PAS 24 certification, new build residential schemes as well as renovation projects can maximise the feeling of open space, safe in the knowledge that the technical quality of this system stands up to stringent security certification standards.”
Approved Document Q of the Building Regulations mandates that all new build homes in England must feature appropriate security protections robust enough to resist force and stop unwanted entry. MasterPatio has been tested to and achieved PAS 24:2022 to meet this requirement.
Both the MasterPatio Bi-Part monorail and two-rail frames systems have been awarded PAS 24 certification offering refined aesthetics with security and performance for safe, beautiful homes. MasterPatio is also robust enough to be used in commercial settings where its very strong sustainability credentials can support in meeting strict project-specific requirements for the specification of highly sustainable solutions.
“The MasterPatio Bi-Part system with PAS 24 certification represents a no-compromise approach to design and security for architects and specifiers looking for centre opening doors that meet in the middle.” added John.
“The product offer also enables fabricators and installers to meet customer desire to maximise open space from door areas with a PAS 24 compliant solution, backed by technical support and high-quality engineering from Reynaers.”
