Marlon ST Longlife is a high performance multiwall glazing material manufactured from damage resistant polycarbonate with co-extruded Longlife UV protection. It is light in weight yet robust and resistant to impact. The extensive range of structures and thicknesses available.

Strength & Impact Resistance | UV protection & Weatherability

Hail, vandalism or accidental damage to roof glazing can be hazardous and expensive to repair. Marlon ST Longlife multiwall polycarbonate glazing is up to 200 times stronger than glass and highly resistant to impact damage making it the ideal glazing material in a wide range of applications where the sheet may be exposed to risk of damage.

This strength is maintained over a broad temperature range making Marlon ST Longlife suitable for use in climates that experience hot
or cold temperature extremes.

• Strong and resistant to impact, 200 times stronger than glass
• Reduces the need for costly repairs and maintains safety on buildings with access to the roof
• Ideal for a wide range of applications including factories and industrial buildings, greenhouses and agricultural buildings or buildings and roof structures in extreme climates.
• UV Longlife protection barrier filters out over 98% of harmful UV radiation protecting the people underneath the sheet from the sun
• UV Longlife protection barrier protects the sheets from weathering and yellowing under the sun and prolongs the life of the sheet
• Marlon ST Longlife has a broad temperature range and will maintain its properties even in extreme weather conditions

Roof Sheet Thermal Insulation

A considerable advantage of Marlon ST Longlife is that it is much more efficient at preventing heat loss than traditional glazing materials of comparable thickness. The U value is used to compare the insulation properties of materials. It measures the amount of heat passing through the material for a unit area for every degree of temperature difference across the material. Therefore the lower the U value the better the material will retain the heat within the building.

Condensation

In our experience condensation, correctly understood as arising from the precipitation of moisture from saturated air, is often used erroneously to describe the effects and results of water ingress into the sheet from outside due to deficiencies in installation. While the former is characterised by misting of the surface, the latter is characterised by the formation of larger discrete droplets within structured sheet.Polycarbonate, being hydroscopic, absorbs moisture from the atmosphere and installations depend on ventilation to avoid saturated air in the cellular structure, which will condense under appropriate conditions.

We find that during the first few months after installation there can be tendency for some condensation to appear, but after a 'settling down' period it will disappear again. However given the hydroscopic nature of the material and unfavourable conditions, e.g. high moisture laden atmosphere, large temperature differentials between inner and outer surfaces of the sheet, low roof pitch, poor ventilation, there are some installations where condensation may be a more or less constant phenomenon. (e.g. low pitch North facing roof.)  Learn more about properly installing multiwall polycarbonate.

Energy Efficient Multiwall Polycarbonate Sheet

The combination of quality light transmission and high thermal insulation provided by Marlon ST Energy Efficient structures provides a greener alternative to artificial lighting and promotes more efficient heating and cooling. Available in a range of structures up to 55mm achieving U-values as low as 0.83W/m2K* Marlon ST is one of the most energy efficient glazing materials available, with better insulation properties than most triple glazing or argon filled double glazing, this glazing material offers a highly effective means of reducing the energy consumption and carbon footprint of a building.
