Polyfoam ECO Cut-To-Falls

For the thermal insulation of new and refurbished flat roofs

Description

Polyfoam ECO Cut-To-Falls are rigid extruded polystyrene boards with Zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of less than five. Polyfoam ECO Cut-To-Falls is a specially designed system of pre-cut tapered high performance lightweight extruded polystyrene boards (xps) with high compressive strength.

Typical board sizes are 1250 x 600 and cut to suit any fall system. The boards are straight edged and can be supplied with a foil facing to suit pvc single ply membrane applications.

Application

Polyfoam ECO Cut-To-Falls is used for thermal insulation of new and refurbished flat roofs. Their built-in fall ensure good drainage of completely flat structural roof decks. Through an expert design and specification service Knauf Insulation can satisfy most projects requiring a cut-to-falls system. Each project will have an individual design to best suit the needs of the building.

Standards

Polyfoam ECO Cut-To-Falls is manufactured in accordance with BS EN 13164:2008, EN 16001:2009 Energy Management Systems, OHSAS 18001:2007 Occupational Health and Safety Management Systems, ISO 14001:2004 Environmental Management Systems, and ISO 9001:2008 Quality Management Systems,as certified by Bureau Veritas.

Durability

The continuous service temperature limits of Polyfoam ECO Cut-To-Falls are -20 to +70º C.

Environmental

Polyfoam ECO Cut-To-Falls is manufactured with a GWP<5 and is free from CFCs,HCFCs and any other material with ozone depletion potential in it’s manufacture and content and represents no known threat to the environment.

Polyfoam ECO Cut-To-Falls is non bio-degradable and 100% recyclable.

Compression resistance

Polyfoam ECO Cut-To-Falls is highly resistant to compression and withstands both occasional and long term static loads. Load bearing construction elements should be designed to adequately support the combination of imposed and dead loads without creating excessive deflection.

Moisture resistance

Polyfoam ECO Cut-To-Falls is resistant to moisture absorption and can be laid in standing water or up against wet concrete with negligible impact on the performance of the product.

Moisture absorption

Polyfoam ECO Cut-To-Falls has a moisture absorption of 1.1% by volume when tested in accordance with EN 12087.

Vapour Resistivity

Polyfoam ECO Cut-To-Falls has a vapour resistivity of 600MNs/g.m.

Fire performance

When Polyfoam ECO Cut-To-Falls is installed in a roof construction it will not contribute to the development stages of a fire. When overlaid with a single ply membrane the performance of the finished roof will depend on the membrane used. Please consult the membrane manufacturer for more details.

Handling and storage

The boards are easy to handle and special protective clothing is not required when installing them. Polyfoam ECO Cut-To-Falls schemes are supplied in component parts in polythene packs, labelled with identifying product and manufacturing data. Ensure the boards are not stored close to open flames or other ignition sources, also avoid volatile compounds and chemicals such as solvents. Polyfoam ECO products should not be left exposed to prolonged sunlight as this will result in surface degradation. Where outside storage for extended periods is required cover with opaque/light coloured sheeting.
