GENERAL SYSTEM MANAGEMENT
Aluminium Fins are commonly used in façade design to add architectural interest as well as control the solar heat gain in a building.
Fins are generally vertical, although can be horizontal in certain circumstances, and are either perpendicular to the façade face or can be set at an angle. Fins are set at an angle to more effectively control heat gain whilst directing visibility from the building in a certain direction or to give privacy where it may be required.
The greatest challenge with Fins in Facade Design is accommodating façade / building movement whilst fins are often designed to look continuous across movement joints. This is controlled by carefully analysing connection details, cantilevers and movement capacity within the fins themselves.
OPTIONS AND FEATURES
Fins can be made from a number of different aluminium designs. Smaller “Blade” fins may be made from rolled plate or extruded solid lengths – up to 16mm thick.
Wider fins – generally up to 80mm wide – to match the curtainwall mullion width, - are generally extruded hollow box sections up to 400mm deep.
Where the fins are considerably larger than this, they are made from an aluminium subframe with aluminium panel cladding.
Being generally formed from aluminium fins are available in a variety of surface finishes to compliment or offset the curtainwall / window finishes.
