\n Multiwall polycarbonate for your project<\/em> <\/h1>\n
\n

Multiwall polycarbonate is a layered material used in structures where light transmission, low weight, and resistance to environmental conditions are important.<\/p>

It is most commonly used in roof and wall systems, greenhouses, industrial and commercial buildings, and lightweight structures.<\/p>

The right solution is selected after assessing the specific structure, loads, dimensions, and required sheet thickness.<\/p> <\/div>\n <\/div>\n

Properties<\/p>\n

\n Key properties of multiwall polycarbonate<\/em> <\/h2>\n <\/div>\n
\n

Properties depend on the specific sheet, thickness, colour, and selected configuration.<\/p> <\/div>\n \n

\n
\n

01<\/p>\n

Thermal insulation<\/h3>\n

The multiwall structure helps reduce heat transfer and provide better thermal insulation in different climate conditions.<\/p>\n <\/article>\n

\n

02<\/p>\n

Light transmission up to 84%<\/h3>\n

Clear sheets can transmit up to 84% of natural daylight.<\/p>\n <\/article>\n

\n

03<\/p>\n

Temperature range: from -40 to +120 \u00b0C<\/h3>\n

The material retains stable properties across a wide temperature range.<\/p>\n <\/article>\n

\n

04<\/p>\n

Filters 98% of UV radiation<\/h3>\n

The protective layer filters more than 98% of UV radiation and helps protect the material.<\/p>\n <\/article>\n

\n

05<\/p>\n

10 \/ 15 \/ 20-year warranty<\/h3>\n

The standard warranty is 10 years. With additional solutions, it can be extended to 15 or 20 years.<\/p>\n <\/article>\n

\n

06<\/p>\n

Behaviour in fire<\/h3>\n

When exposed to fire, polycarbonate melts without producing burning droplets. The specific fire-reaction class depends on the product and is stated in the technical documentation.<\/p>\n <\/article>\n <\/div>\n <\/div>\n<\/section>\n

\n

03<\/p>\n

\n \n 200<\/span>\n \u00d7<\/span>\n <\/span>\n <\/p>\n

more impact-resistant than glass of the same thickness<\/p>\n <\/article>\n <\/div>\n \n

\n

Multiwall polycarbonate sheets offer high impact resistance while remaining lightweight. Depending on structure and thickness, sheets weigh 0.55\u20133.2 kg\/m\u00b2.<\/p>

The stated values are indicative and may vary by product. Project decisions must be based on the technical documentation for the selected sheet.<\/p> <\/div>\n <\/div>\n<\/section>\n
