Pitched roof Insulation

The simple, effective combination for warm pitched roofs Platinum Warmsark and Platinum Warmsqueez are two highly efficient, exceptionally cost-effective products for insulating warm pitched roofs at the rafter line. Used together or individually these products will make a significant contribution to energy efficiency.

Both products are manufactured from Platinum EPS – material which incorporates a graphite component called Neopor®, manufactured by BASF to provide significantly improved thermal insulation performance, for example, to achieve higher levels of the Code for Sustainable Homes or just to improve SAP ratings.

Platinum Warmsqueez

Platinum Warmsqueez is a versatile thermal insulation panel that is specially cut to compress and then expand into position between the rafters and trusses to become self-retaining. It is available in 1200mm x 600mm boards and in a wide range of thicknesses.

Platinum Warmsark

Platinum Warmsark is a high duty thermal insulation panel with tightly interlocking tongue and groove joints on all edges developed specifically for use over the rafter plane in pitched roofs. The Warmsark layer completes the thermal envelope and combines with Warmsqueez to provide an exceptionally efficient thermal barrier with no cold bridging.

Sustainability

The environmental integrity of Platinum Warmsark and Warmsqueez products is exceptional:

  • Zero ODP (Ozone Depletion Potential)
  • <5 GWP (Global Warming Potential)
  • A+ BRE Green Guide rating for generic EPS products
  • CFC, HFC and HCFC free
  • Contain recycled content
  • Boards are 100% recyclable

Durability

The thermal insulation properties of Platinum Warmsark and Warmsqueez products will remain effective for the life of the building. The cells in the board contain air, ensuring consistent performance during the lifetime of the products.

They are dimensionally stable products, which are resistant to attack from bacteria, moulds and fungi, and will not provide nutrient value for insects or vermin. They are also non-toxic and non-irritant.

Certification

Platinum Warmsqueez and Platinum Warmsark have been awarded BBA certificate No: 94/3051. The products are manufactured to the requirements of BS EN 13163:2001 and under an ISO 9001:2000 approved quality management system.

Behaviour in relation to fire

Platinum Warmsqueez and Platinum Warmsark do not prejudice the fire performance properties of the roof if used as recommended in BS 6203:2003 and are unlikely to become ignited when properly installed.

The Reaction to Fire Classification of the boards as supplied to the market is Euroclass E. However, the classification of construction works incorporating Platinum Warmsqueez and Platinum Warmsark boards (end use conditions) will be considerably better. When used in warm roof constructions Euroclass B can be expected.

Services

Platinum Warmsqueez and Platinum Warmsark boards must not be used in direct contact with PVC sheathed electrical cables or hot water pipes. Electrical cables should be enclosed in suitable conduit.

Handling and Storage

Springvale Platinum Warmsqueez and Platinum Warmsark panels are delivered to site wrapped in opaque polythene. Store panels in the original wrapping under cover and protect from direct sunlight. Keep panels above ground level and out of contact with solvents and materials containing volatile organic compounds such as coal tar, pitch or timber recently treated with creosote. Do not expose to naked flame or other ignition sources during storage or installation. Combinations of Platinum Warmsqueez and Warmsark will achieve the following values:
