RAINSCREEN CLADDING

Rainscreen Panels consist of an outer weather-resistant decorative skin utilising many types of lighweight panels such as ACM, PPC aluminium, terracotta tiles, ceramic granite to name but a few; fixed to a primary structure by means of an adjustable supporting grid. This maintains a ventilated and drained cavity between the façade and the structure.

Rainscreen façades are not normally sealed, and a ventilation cavity of at least 25mm is allowed immediately behind the cladding panel. Insulation can be placed within the cavity if required, while openings at the top and bottom of clad areas allow for evaporation of moisture vapour, ventilation and drainage. Composite panels may often provide a quick and cost effective means of providing the insulation. A ventilated rainscreen incorporating insulation will still allow the building fabric to breathe without risk of interstitial condensation or structural decay.

External wall insulation used in this way is superior in performance as it eliminates the condensation risks associated with internal or cavity wall insulation – particularly important for refurbishment schemes. In newbuild, use of back-ventilated rainscreen cladding provides the opportunity to use economical, single skin, load-bearing blockwork for infill walls.

At TASK-UK we are equipped with very experienced rainscreen design capabilities and rainscreen installers. Our design team consists of individuals who have not only worked on existing systems, but have also developed systems that are now in the market place and have been used on large scale rainscreen projects in the UK.

SECONDARY STRUCTURAL CLADDING SUPORT SYSTEMS:-

  • INSULATED COMPOSITE PANELS:-

An insulated sandwich panel consisting of a steel outer and inner skin with an insulated core to give the required ‘U’ Value is fixed to a primary steel support system. The panels are interlocking and also sealed to each other to give an even flat surface. The outer skin can be pre-painted and the joints in filled with joint strips for a finished look; alternatively, decorative panels with our without an adjustable support grid can be fixed to the outer face of the panel to give a more architectural finish as required. This is a very fast system to install and is not weather dependant.

  • SFS (LIGHTWEIGHT GALVANISED COLD ROLLED STEEL FRAMING)

Lightweight galvanised ‘SFS’ stud and track can be used to infill between primary structures such as reinforced concrete floors / columns etc. Deflection needs to be accounted for between floor slabs and our design and installation teams are fully adept at detailing, scheduling and installing these systems. A sheathing board can then be fixed over the external face of the SFS and the gaps sealed. A membrane such as a breather membrane is then fixed over the face of the sheathing board to water seal the outer skin and allow the build-up to breath so that any water left on the inside of the board can evaporate out. Cladding support grids can then be fixed over the face of the sheathing board into the SFS behind and this allows the decorative panels to then be fixed over. Again, thermal and deflection movements need to be accounted for in the design and installation together with interface details between windows, roofs, floors, penetrations, etc. On the inside of the SFS, plasterboards sheets can be fixed directly over taped, jointed and plastered then painted giving a full through wall solution from external facade through to internal decorated walls.

 

WINDOWS & CURTAIN WALLING

We can design and install many types of windows and curtain walling systems.

When glass is used as the curtain wall, a great advantage is that natural light can penetrate deeper within the building. The curtain wall façade does not carry any dead load weight from the building other than its own dead load weight. The wall transfers horizontal wind loads that are incident upon it to the main building structure through connections at floors or columns of the building. A curtain wall is designed to resist air and water infiltration, sway induced by wind and seismic forces acting on the building, and its own dead load weight forces.

Curtain wall systems are typically designed with extruded aluminium members. The aluminium frame is typically in filled with glass, which provides an architecturally pleasing building, as well as benefits such as daylighting.

Curtain walls differ from store-front systems in that they are designed to span multiple floors, and take into consideration design requirements such as: thermal expansion and contraction; building sway and movement; water diversion; and thermal efficiency for cost-effective heating, cooling, and lighting in the building.

 

THROUGH WALL SOLUTIONS

We at TASK-UK are passionate about delivering full through wall solutions from the decorative architectural outer skin through to the internal drylining walls together with windows and curtain walling, closer trims, flashings, copings etc. etc. All that is required is a primary structure by others and we will do the rest. Our management have many years experience in all of the above and we look forward to working with you on your next project.
