At the onset of every project you will need to define the design parameters, such as wall condition / type and project windloads. What type of wall construction is being used on the project? (In North America, stud/ sheathing or block/tilt-up are the most common.)

During the Design Phase, we start working through The 5 Principles, beginning with the cladding material selected. It is critical to understand the material deflection and thermal properties, spanning capabilities and water absorption of the cladding material, as these factors will influence the engineering of the substructure and the overall wall assembly. Next, comes consideration for the panel joint design and depth of cavity space behind the wall cladding. During this process you must consider the degree of water infiltration within the system and panel joint design. As you consider cavity depth, you will need to evaluate the goals for insulation, R-values and depth of system.

After these criteria are evaluated, the focus can now turn to which attachment system will best suit your project. Depending upon what type of wall construction is being used, you need to select a horizontal or vertical system. Next, do you prefer a visible or concealed mounting system? (As a rule of thumb, visible or face-fastened systems tend to be less expensive to install than concealed systems.)


How to Design a Rainscreen

By selecting a Cladding Corp System5 fully-engineered rainscreen solution, you can rest assured that each of The 5 Principles of a properly designed drained and back-ventilated rainscreen is adequately addressed per your project’s unique criteria.

Principle 1 principle1_cladding– CLADDING MATERIAL SELECTION

Cladding Material Selection: Select and understand the performance characteristics of the cladding product

principle2_outermoisturePrinciple 2 – OUTER MOISTURE CONTROL

Outer Moisture Control: Design cladding and joints to deter water from entering system cavity

principle3_cavity2Principle 3 – CLADDING CAVITY DESIGN

Cladding Cavity Design: Design the cladding cavity with a specific focus on ventilation, thermal and acoustic performance

principle4_subframePrinciple 4 – ENGINEERED SUBFRAMING

Engineered Subframing: Design substructure system with a focus on material, structural and seismic performance

principle5_innermoisturePrinciple 5 – INNER MOISTURE CONTROL

Inner Moisture Control: Design air/water barrier with a focus on flashing details and backup wall type
