Description
TopEcoStud (patent pending) is a thermally engineered composite of high performance extruded polystyrene bonded to Oriented Strand Board 3 (OSB 3). The OSB 3 component is sourced from FSC certified forests.
EcoStuds are used for the thermal insulation of solid walls and are installed as part of the ThermoShell Internal Wall Insulation (IWI) System along with Earthwool EcoBatt.
They are available in a variety of sizes to suit the thermal performance requirements of individual projects.
Standards
The extruded polystyrene component of EcoStud is high performance, 100% ozone friendly, lightweight, rigid insulation. It has excellent structural strength, high compression resistance, unaffected by moisture and is manufactured in accordance with BS EN 13164: 2008 and BSI Quality Assurance Standard BS EN ISO 9001: 2008.
The OSB component of EcoStud is manufactured to the specification detailed in BS EN 300: 1997 for OSB/3.
Durability
EcoStuds are tough, thermally engineered products and suitable for use in the temperature range of -50 to +75º C.
Thermal
The extruded polystyrene in EcoStud has a thermal conductivity of 0.030W/mK, the Oriented Strand Board has a thermal conductivity of 0.130W/mK.
Benefits
• Excellent thermal performance
• High compressive strength
• Highly resistant to water absorption
• Structurally stable in the long term

Vapour Resistance - resistivity
The extruded polystyrene component of EcoStud has a water vapour resistivity of 480 MNs/gm. The OSB component of EcoStud has a water vapour resistivity of 250 MNs/gm.
Environmental
EcoStud is free from CFCs, HCFCs and any other material with ozone depletion potential in its manufacture and content, represents no known threat to the environment and is recyclable.
Moisture Resistance
The extruded polystyrene component of EcoStud is unaffected by moisture. Before installation EcoStud should be conditioned as close as is practicable to the environmental conditions likely to occur in service. The moisture content of the OSB component should under no circumstances exceed 15%.
Handling and Storage
EcoStuds are easy to handle and install, being lightweight and easily cut to size. They are supplied in polythene packs which are designed for short term protection only. For longer term protection on site, the product should either be stored indoors, or under cover and off the ground. EcoStuds should not be left permanently exposed to the elements.
