Domes are made of PMMA (polymethyl metacrylate, acrylate glass). The PMMA thickness is 2 - 3 mm. The dome is made by thermal moulding. Individual layers are screwed together into one compact block. There is also a double side sticking waterproof adhesive tape between individual layers. Each dome has a sealing, which is in contact with the collar. All domes are delivered with necessary screws and fixtures.


Thermal insulation properties of domes:

  • single layer dome       U=5.6 W/m²K
  • double layer dome      U=2.4 W/m²K
  • triple layer dome        U=1.8 W/m²K
  • four layer dome         U=1.3 W/m2THERMOPUL energy efficient domes

Color schemes:

We manucture our domes in two various color schemes

  • Transparent (clear) - light transmission 92%
  • Opal (milk) glass with practically similar light transmittance (81%) but not transparent
If you need different colors or design do not hesitate to specify your needs and we shall make a dome in a color of your choice.
Alternative materials
  • PC (polycarbonate) in comparison to glass polycarbonate is 300 x more resistant. Demonstration - see Fig. 2 Colour - clear (transparent)
  • Heatstop - when using this material, the cupola gets excellent heat reflecting properties. This material reflects up to 68% of the sun rays, which eliminates interior overheating. Colour - pearly white (non transparent but translucent)
  • Solar control IR this material combines advantages of PC (polycarbonate) and Heatstop. It is very resistant against mechanical damage and reflects up to 65% of sun rays. Colour - bronze (smokey), translucent.
Flammability classes (European classes):
  • Dome made of PMMA: C3
  • PVC frame: C1
  • Glass fiber collar: B

Base shapes

  • Square
  • Rectangle
  • Circular
