Matrix SF Rainscreen Cladding

The CWCT tested Matrix SF (Secret Fix) rainscreen cladding system is a high tolerance fabricated panel generally supplied in 3mm thick which is dictated by the material type and panel size.

Our rainscreen facade systems provide an aesthetically pleasing external envelope solution whilst also offering rapid installation times. PSP provide a comprehensive range of integrated metal rainscreen facade systems that can be adapted to suit specific client needs and provide a solution for almost any building type.

The CWCT tested Matrix Secret Fix Cladding system is a high tolerance fabricated panel generally supplied in 3mm thick which is dictated by the material type and panel size.

Special features, pressings and louvers can be manufactured from single skin material ensuring it matches that of the panels.

This rainscreen system is ideal for integrating perforations into the panel; these can be designed to integrate anything from uniform lines to random patterns or pictures.

PSP’s Matrix SF rainscreen system is available in a range of materials such as COR-TEN®, Stainless Steel and Aluminium. The most suitable type of secondary support structure is generally dictated by the panel orientation along with the ability to incorporate thermal and floor movements where required.

This Matrix Secret Fix Cladding system offers a variety of benefits:
  • Fully tested and accredited rainscreen system to CWCT standards
  • Quick and easy installation to backing structure
  • Allows for a variety of colours and finishes
  • Panels can be manufactured in lengths up to 6m
  • Allows for both floor and thermal movements

Fixing Details:

Matrix SF Carrier System:

The “T” Rail system is probably our most popular system. Brackets are manufactured in house accommodating most cavity depths. The system is fitted vertically and best utilised where panels are horizontally laid however it can accommodate horizontal panels with rails at each vertical joint and/or the introduction of a z/top hat.

T Rail’ Secondary Support Carrier System:

Our ‘T Rail’ Secondary Support Carrier System is designed for ease of installation and versatility of use. Typical facade systems and materials may be fixed to the secondary support carrier including Honeycomb Core, Coated Aluminium, High Pressure Laminate, Timber and Zinc. Utilising our purpose developed software program we can provide structural calculations and assist with the design for each specific project, backed up with rigorous CWCT testing.

Secondary Support Grid system build-up: When the external facade is attached to the carrier system, allowance is made for the expansion, contraction, dead load and dynamic load. Typically, rails will span from floor to floor with a break in the vertical rail where structural deflection is required.

T and L Rail:

The T and L Rail are manufactured from high quality structural grade extruded aluminium in 6000mm lengths as standard; these can then be cut to length. Both items can be supplied with a PPC finish, or a cover trim can be supplied if required. All facades are fixed directly to the face of the carrier as per the facade manufacturers’ recommendations. The versatility of the Matrix T Carrier Secondary Support Grid System allows vertically orientated facades to be attached using the CNC pressed Z rail where required.


Brackets are manufactured from 3mm Aluminium and consist of 3 types, supplied with a minimum arm length of 90mm in increments of 20mm upwards to 350mm. All bracket types may be fixed to varying substrates including Steel, Block Work, Concrete and Timber.

Thermal Isolator Pads:

Thermal break isolator pads may be supplied where required to your secondary support grid. They feature low thermal conductivity, optional pre-punched pads and all are manufactured from rigid PVC.

Matrix SFM

Matrix SFM is a CWCT tested rainscreen system based on Matrix SF but includes mullions for structural support. Panels are available in a range of materials such as Stainless Steel and are manufactured in lengths up to six metres.

Matrix SFC

Matrix SFC rainscreen system is made of pre-coated metal composite materials such as ACM, ZCM, CCM and is manufactured on our flatbed CNC machine offering high tolerances and sharp folds. Available in a range of finishes.

Matrix SFCM

This CWCT tested Matrix SFCM rainscreen system is based on the Matrix SFC system which uses pre-coated metal composite materials but includes mullions for structural support. Available in a range of finishes.

Matrix IP

Interlocking plank rainscreen system can be laid vertically or horizontally and are developed to provide a single skin panel at an economical price based on narrow face widths. Pressings and louvers can be the same material as the panels.
