Structures & Tints

Multiwall polycarbonate sheet is a lightweight insulating glazing material manufactured from damage resistant polycarbonate. Co-extruded UV protection provides resistance against the effects of UV weathering. Marlon ST multiwall sheets are available in a range of thicknesses, structures and options for a wide range of roofing, cladding and glazing applications.

Natural Daylight with Minimal Heat Loss.

Clear multiwall polycarbonate sheets can achieve excess of 80% light transmission making it an ideal material for providing maximum daylight into a building. A range of tints are also available for varying degrees of solar control. The thicker, thermally insulating sheets bring free natural daylight into the building with minimal heat loss increasing the overall energy efficiency of the building.

Multiwall Properties

Incredible Strength to Weight Ratio

Polycarbonate’s strength to weight ratio makes it an ideal material for roofing and glazing applications and an excellent alternative to heavier building materials. 

200 times stronger than glass at only a fraction of the weight

Long term durability means lower maintenance

Superb glazing solution suitable for even the most extreme of climates

Excellent impact
resistance

Weight allows for architectural designs that could not be realised with heavier materials

Light weight for reduced transport costs and ease of handling.

Multiwall Properties

Excellent Light Transmission

Polycarbonate’s optical qualities make it ideal for applications requiring maximum daylight. Clear Marlon ST can achieve more than 80% light transmission reducing the need for artificial lighting and reducing the running costs of a building. A range of standard and non-standard tints are available offering a more controlled light transmission,

Achieves light transmission in excess of 80%

Natural daylight increases productivity and performance in schools, workplaces and sports facilities

Natural daylight has been proven to promote health and wellbeing and improves mood

Reduced need for artificial light cuts building energy costs

Range of tints offering differing levels of light transmission and light diffusion to meet the designer’s requirements

The ideal choice for a range of construction, horticulture, agriculture and DIY applications

Multiwall Properties

Outstanding Technical Performance

Polycarbonate offers a wide range of technical properties that make it an ideal solution in even the most challenging environments. It is a thermally insulating glazing material which brings natural light into a building whilst reducing heat loss through the glazing. 

Service temperature up to 100°C - suitable for high temperature internal or external environments

The multiwall structure of Marlon ST sheet provides a thermally insulating glazing solution.

Co-extruded UV protection layer filters out over 98% of UV rays for enhanced weatherability, preventing yellowing and loss of strength.
