Winter garden construction

One of the most popular methods of roofing a winter garden is a glass roof or a roof made of solid or cellular polycarbonate. In the first case, the roofing of the garden is often exposed to an unsightly appearance after rain or snowfall, which results in the need to frequently wash the roof from its outside, which, let’s face it, is not one of the most pleasant activities. The roof of the winter garden is also exposed to mechanical damage caused by, for example, falling tree branches or hail balls. Therefore, the glazing is most preferably made of toughened or laminated glass.

Roofing of the winter garden and winter garden walls

The solution to the above problems may be the construction of the roof of the garden pavilion with a rigid, light Classic-Therm® panel, our production. Ostrowski sandwich panels for winter gardens provide excellent thermal insulation, and hence – a comfortable temperature in the interior, shade and, importantly, sound attenuation (acoustic insulation) from the environment as well as absorption of noise from precipitation. The issue of the board’s resistance to damage is also important.
