Lattensystems

Lattensystems refer to assemblies of battens arranged in a grid or lattice pattern to form a supporting framework for cladding, insulation, or decorative elements in buildings. They are commonly used to create ventilated facades, allowing air flow behind the outer layer while supporting the exterior or interior finish.

Common configurations include horizontal, vertical, or diagonal battens, sometimes forming two- or multi-layer lattices. Materials vary: timber battens (softwood or hardwood), metal battens (aluminum or steel) with protective coatings, and composite or polymer-based battens. Material choice depends on climate, fire safety, load, and aesthetics.

Functions of lattensystems include supporting cladding, enabling drainage and ventilation to reduce moisture buildup, providing daylight and shade control, and sometimes contributing to acoustic performance by creating spacing and cavities. They are used on building facades, ceilings, interior partitions, and in pergola or roof screen applications.

Installation considerations include proper detailing to manage moisture and thermal movement, fire safety and compatibility with cladding materials, corrosion resistance for metal options, and correct spacing to achieve drainage and ventilation. Building codes may specify fire ratings and wind-load requirements for exposed battens.

Advantages of lattensystems include lightweight construction, ease of installation, and design flexibility. Limitations include limited structural load-bearing capacity, potential maintenance needs for timber (decay, rot, pests) and corrosion or wear for metal options, and possible thermal bridging if not designed with proper detailing.
