Materials for conservatories
Customer preference as well as static requirements determine which materials are used for the supporting structure. In most cases we use aluminium because of its significant advantages.
These materials can be used:
Aluminium
Aluminium
Extruded aluminium sections, thermally separated (AlMg-Si 0.5; F 22) with controlled pre-chamber draining and APTK center seals. Thermally separated systems for stud and rail constructions. (resistance to heavy rain acc. to DIN 18055 group C).
Material proprieties
- noncorrosive
- surface refinement by means of anodisation, lacquer or powder coating
- high strength but light weight
- filigree look
- suitable for welding (additional static and creative potential)
- large variety of sections
- low-maintenance and durable
- built-in lighting optional
- good heat insulation due to thermal separation (multi chamber systems)
- minimal thermal expansion of glass due to patent glazing (no putty)
- non flammable / recyclable
Steel
Cold or hot formed steel hollow frame sections and/ or rolled shaped steel (S235JR, corrosion-proof)
Material properties
- high load-bearing capacity and resilience
- small but simple cross-sections
- susceptible to corrosion
- filigree look, high strength
- suitable for welding
Timber
Glue-laminated hard or soft wood; timber for window manufacture acc. to DIN 68360. For load bearing structures only glued trusses made from spruce or fir are admitted for use by the supervising authority.
Material properties
- good heat insulation
- natural product (renewable resource)
- good workability
- large cross-sections (caused by low strength and plastic deformation)
- sensitive to weather
- wood keeps moving
Aluminium-timber combined
Timber conservatory with outside aluminium sections for weather protection.
