Materials for conservatories
The choice of construction material for the supporting structure is determined by the customer’s requirements and static requirements. In most cases aluminium is used due to its convincing advantages.
Aluminium
Extruded, thermally separated aluminium composite profiles made of AlMg-Si 0.5 F22, with controlled prechamber drainage and APTK centre seals or thermally decoupled systems for mullion-transom construction (driving rain resistance according to DIN 18055 group C).
Material properties
- corrosion-resistant
- Surface finishing by anodizing or painting (e.g. powder coating)
- high strength at low weight
- filigree look
- suitable for welding (additional static and design possibilities)
- Profile variety through extrusion technology
- easy to clean and durable
- Halogen or LED spotlight possible in rafters
- high energy consumption for material extraction and production, relativized by considerable longevity
- good thermal insulation due to thermal separation (multi-chamber systems)
- Thermal expansion of the panes is absorbed very well, as the glass is glazed without any putty
- non-combustible / recyclable
Steel
Cold or hot formed hollow steel sections or rolled shaped steels (made of S235JR, corrosion protected)
Material properties
- high load-bearing capacity and elasticity
- small, but simple cross-sections
- susceptible to corrosion
- filigree look
- high firmness
- suitable for welding
Aluminium - wood
Wooden conservatory with weather protection by aluminium outer profiles.
Material properties
- see wood and aluminium
Wood
Laminated deciduous or coniferous woods; woods for window construction according to DIN 68360. Only laminated spruce-fir beams are approved by the building authorities for load-bearing structures.
Material properties
- good thermal insulation
- Natural product (renewable raw material)
- good workability
- large cross-sections (due the low strength and creep deformation)
- weather-sensitive
- Wood works
