Cladding Flashcards
Understand types of cladding
What is Cladding?
Cladding forms the enclosure of the building, or the skin, and is often used to mask the structural frame.
What are the types of cladding systems?
Cladding systems include:
* metal panel systems
* fibre reinforced panel systems
* concrete panel systems
* glazed curtain walling
* rainscreens
Where are cladding systems typically positioned?
Cladding systems are positioned immediately outside the line of the structural frame, often hiding the skeleton completely.
What are Infill Panels?
Infill Panels are set between the component parts of the structural frame, exposing some or all of the structural members.
What materials can be used for infill panels?
Infill panels can be made from a variety of materials, including:
* timber
* steel
* aluminium
* Brick
What are the functional requirements for cladding?
Functional requirements include:
* Secure fixing to structural sub-frame
* No distortion or ripple in flat panels
* Easy transportation and installation
* Easy replacement of damaged panels
* Accommodation of thermal expansion and contraction
What must cladding panels resist?
Cladding panels must resist:
* metal fatigue
* rust
How should cladding systems address sound insulation?
The system should insulate occupants from airborne sound and impact sound should not be readily audible within the building.
What glazing is required for windows in cladding?
Windows must be double or triple glazed in response to local climate needs.
What should be minimized through windows?
Solar heat gain through windows is to be minimized.
What design features are necessary for joints between cladding panels?
Joints must:
* Resist wind driven rain
* Channel water to safe discharge
* Be regularly inspected for seal degradation
What ventilation requirements exist for windows?
Windows should be openable for ventilation, restricted to 100mm on first operation, and cleanable from inside the building.
What fire safety measures must be in place for cladding?
Fire must be prevented from spreading via the space behind the cladding, and surface spread of flame characteristics must comply with Building Regulations.
What structural requirements must panels meet?
Panels must resist wind suction and surcharge, and metal must be of sufficient thickness to cope with applied stresses.
What is the minimum life expectancy for factory applied paint on cladding?
Factory applied paint must have a minimum life expectancy of 20 years.
