We use practically all kind of glazed glass. We usually use double glazing units with the overall heat transfer coefficient U-value U= 1,1 W/m2K. On the roof we mount tempered and laminated and safety glass VSG 33.1. We can use tinted or reflective glass. We are able to mount double or triple panes, also with unusual shapes (trapezoids, triangles, arcs, circles and other shapes by customer template).

On the roof terrace we also use five chamber polycarbonate sheets. Features are the following:

• high thermal insulation (U- value to 1.0 W/m2K),
• resistance to weathering,
• high light transmission (gives almost as much light as glass, ensures uniform dispersion of light),
• light weight,
• anti-UV protection layer,
• high temperature resistance: an operating range of -40 to 135 ° C,
• easy to form (it can undergo plastic deformations without cracking or breaking).
