colours for aluminium conservatories, windows and doors

 Every KELLER home conservatory and every KELLER window system is manufactured to the individual needs and requirements of our customers. Their individuality is manifested in unique form and future use but also in the right choice of materials, the surface quality and the colour. Our products thus merge perfectly with your expectations and budget framework.

Floor plan and roof shape

The KELLER GLASSHOUSE® is striking for its clear, simple basic form. The unique feature of the KELLER ORANGERIE® lies in its various four or more-sided constructions. The resulting circumference determines the form, design and quantity of the glass dome/s, which can be strictly symmetrical, round, L-shaped or (weight-bearing) flat glass.

The eaves profile

The eaves profile dictates the style of the KELLER ORANGERIE® or the KELLER GLASSHOUSE®. The PRESTIGE profile lends the conservatory a classic, elegant air while the STRAIGHTLINE and GLASSHOUSE® profiles have clean modern lines and emphasise the timeless discretion of the conservatory construction.






The special flat roof structure

a KELLER innovation

The special flat roof structure opens up whole new possibilities in home conservatory construction. It offers a variety of advantages compared to the conventional glass single-pitch or gable roofs. Where footprint or room depth is limited by a low cornice, the special flat roof structure allows you to extend your floor area as much as you like. This construction method allows large footprints and flexible connection to the existing building



Energy saving and efficiency

Particular attention is paid to energy saving and energy efficiency. The roof design especially allows high thermal insulation at the passive house level. The special flat roof construction achieves a U-insulation coefficient of 0.40, which is the equivalent of a brick wall. Lighting, audio, climate control and sun protection can all be flawlessly integrated on request. Furthermore, the roof construction can be designed to be weight-bearing and used as a patio.

Glass and special glass

Glass as a material plays a key role in conservatory and window constructions. Firstly, glass lets in light and maximum transparency. Secondly, modern glazing meets the requirements for increased energy awareness. Triple insulated glazing is used more often nowadays. In combination with thermally-insulated aluminium profiles, it offers excellent thermal insulation, even up to passive house level.



Special glass types with special characteristics are also available:

1. Sun-protection glass HEAT MIRROR® for side, roof or flat-roof glazing (can take human weight)

2. Safety glass types from P4A (burglar-proof glass)

3. Safety glass for overhead and roof glazing (LSG)

4. Noise insulation glass

5. Bullet-proof glass (on request)

6. Privacy protection glass with or without sandblasting

7. Decorative glass

8. Glass-to-glass corners made of insulation glass

9. Glass with controllable transparency (privacy glass)



Colours & surface finishes

As well as the shape, profiles and design details, one thing in particular influences the appearance of your personal home conservatory and window system: the colour.

We offer a wide range of RAL and anodised colours and coatings in stainless steel look. . Whether gloss, matt or textured surfaces in your desired colour, style and appearance are perfectly and harmoniously matched to the existing building and to your personal taste.



Aluminium, a top quality material

For our conservatories and window systems we work exclusively with aluminium. Aluminium offers precisely the properties needed to create products of enduring quality and strikingly slim lines:

  • Extremely slender and narrow profiles
  • High stability and rigidity
  • Flawless fit and finish
  • Excellent insulation values for great living comfort
  • Long-lasting
  • Weather-resistance
  • Minimal care and upkeep



Fittings, uprights and decorative elements

Like our customers, here at KELLER we pay extra attention to details. You can choose between different fittings types and KELLER’s own decorative elements, or between different decorative uprights. These details turn your home conservatory into a unique structure, never to be repeated.
