6MM Multiwall Polycarbonate

Reference: 6mm Multiwall Polycarbonate
Structure: Twinwall
Colour: Clear
Length: 6m as standard, other lengths cut to size
Width: 2.1m as standard, other widths cut to size

Our 6mm multiwall polycarbonate sheet combines high light transmission, thermal insulation and excellent weather resistance.

The sheet is lightweight, impact resistant and easy to install. It features a co-extruded UV-protective layer on one side of the sheet which provides almost total resistance against degradation caused by UV radiation in sunlight and almost no UV radiation passes through the sheet. This UV protected side must be installed facing outwards.

Our range of multiwall sheet carries a Ten Year Limited Warranty against discolouration, loss of light transmission and/or loss of strength due to weathering.

  • Non-standard lengths are available to order, minimum quantities will apply
  • Non-standard colours may be available, minimum quantites will apply
  • Cut-to-size available, all sheets are blown free of dust and taped
  • Due to orders for 6mm not being a regular occurence, we will cut to size for you, however, you will always be charged for the full 2100mm width by either the 3m or 6m length.

Maximum Service Temperature (without load)

Our multiwall polycarbonate sheet can be installed in a diversity of applications with varying temperatures. The material’s mechanical performance is known to remain stable in prolonged service in temperatures between -40°C up to 120°C.

Fire Performance

Our multiwall polycarbonate sheet has good fire behaviour characteristics, and receives high ratings in several major European fire performance tests. As a thermoplastic, our multiwall polycarbonte will melt under the intense heat of a fire, however, it will make almost no contribution to a fire through flame spread.
