Domes
The domes are made of acrylic glass (PMMA) or polycarbonate (PC). Depending on the shape, the domes are classified as convex and pyramidal. On a regular basis, the domes are delivered clear or opal, made from one, two or three layers.

Individual layers are glued and sealed with silicone cement. The domes are fastened to the supplied sleeves by means of stainless bolts; the joint itself is protected by a plastic cap.
The domes can be supplied individually without the bottom sleeves. When mounting individual domes on the current rims or sleeves, it is important to adhere to the mounting manual attached to the dome. Domes can also be supplied in other colour shades.

New material of the domes
We extended our assortment by domes made of the HEATSTOP material. If this material is used, the dome has excellent thermal reflection properties; it reflects up to 2/3 of incident heat radiation, which eliminates overheating the building interiors in the summer months (a standard dome reflects just 1/3 of the heat and 2/3 of the received heat warms the building interior).
