Rigid extruded polystyrene (XPS) boards for inverted, blue and green roofs.

Jump to:
BOS
+44 (0)142 9855100 Website

Application

Thermal insulation of a wide variety of flat roofs including:

  • Inverted roof below ballast or paving slabs;
  • Green/ garden roof;
  • Blue roof;
  • Conventional warm roof.

Description

A rigid extruded polystyrene (XPS) board for use in inverted and green roofs.


Features and benefits:

  • Excellent thermal performance.
  • 15 mm lap joint.
  • High compressive strength.
  • Highly resistant to water absorption.
  • Able to resist repeated freeze/thaw cycles.
  • Lightweight and easy to install.
  • Tough and durable, not easily damaged.
  • Dimensionally stable.
  • Thermal performance of an inverted roof is improved when used in conjunction with ‎Polyfoam Slimline Zero Membrane (specified separately).
  • Has a low Global Warming Potential (GWP) of less than five and zero Ozone Depletion Potential (ODP).


Technical characteristics:

  • Vapour resistivity: The XPS content of Polyfoam Roofboard Extra has a water vapour resistivity of 625 MNs/g·m when tested in accordance with EN 12086.
  • Moisture absorption: 0.7% by volume when tested in accordance with EN 12087.
  • Durability: Continuous service temperature limits up to +70ºC.


Typical project types:

  • Mixed use.
  • Domestic.
  • Industrial.
  • Commercial.
  • Education.

Specification data - Extruded polystyrene (XPS) boards

Standard

To BS EN 13164.

Guidance for specification option:

Manufactured in accordance with BS EN 13164, ISO 50001 Energy Management Systems, OHSAS 18001 Occupational Health and Safety Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management Systems, as certified by Bureau Veritas.

Third-party certification

BES 6001, UKCA, UKNI & CE Marked to BS EN 13164 and conforms with the Construction Products Regulation, BBA 17/5454, Environmental Product Declaration; BBA Certificate 17/5454.

Fire performance

To BS EN 13501-1, Class F.

Compressive strength (minimum) at 10% compression

300 kPa.

Guidance for specification option:

Highly resistant to compression and withstands both occasional and long term static loads. The high compressive strength and rigidity of the product allows a range of ballast material including gravel, soil and concrete slabs to be used as part of the construction.

Load bearing construction elements should be designed to adequately support the combination of imposed and dead loads without creating excessive deflection.

Thermal conductivity (maximum)

0.033 W/m·K.

Thickness

50 mm.

Face size (length x width)

1250 x 600 mm.

Edges

15 mm lap joint.
