Hemsec SIPs - 11 mm OSB Facings

Application

  • SIPs for all internal and external walls and roofs in domestic, industrial and commercial construction. An entire building can be manufactured using SIPs for walls, floors and roofs.
  • Suitable for applications where there is a need for thermal efficiency. Depending on how they are used, a building manufactured using SIPs can out-perform most Passive House measures for low-energy use.

The SIPs are suitable for the following applications:

  • Housing.
  • Education.
  • Hotel and Leisure.
  • Retail.
  • Commercial and industrial.

Warranties for SIPs construction are available from companies that offer warranty schemes. Hemsec SIPs are BBA/ National House Builder Council (NHBC) approved and are eligible for Premier Guarantee.

Description

Structural insulated panels (SIPs) manufactured using British Board of Agrément (BBA) approved 11 mm internal and external oriented strand board (OSB) grade 3 facings.

Manufactured to EN 13986 and EN 300:2006 standards, OSB/3 comprises of strands of softwood bonded together using a formaldehyde-free synthetic resin. The OSB boards are responsibly sourced and comply to Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC) chain of custody requirements.

Features and benefits:

  • CE and BBA Certified product, extensively tested for Structural, Acoustic and Thermal properties, including Fire Resistance.
  • Easily integrated with a wide range of construction materials as a load or non-load bearing structure.
  • Combined structure and insulation reduce wall thicknesses, maximising internal build space without compromise.
  • Loss Prevention Certification Board (LPCB) certified.

Applications:

  • SIPs for all internal and external walls and roofs in domestic, industrial and commercial construction. An entire building can be manufactured using SIPs for walls, floors and roofs.
  • Suitable for applications where there is a need for thermal efficiency. Depending on how they are used, a building manufactured using SIPs can out-perform most Passive House measures for low-energy use.

The SIPs are suitable for the following applications:

  • Housing.

Panel core:

  • A closed cell Polyurethane rigid foam system with zero ozone depletion potential (ODP) supplied by BASF Polyurethanes Europe.
  • The PUR core is chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFC) free providing a <5 value for global warming potential (GWP), as specified by various regulatory bodies.

Fire performance:

Panel Internal and External OSB and CPB facings have Class 3 surface spread of flame to BS 476-7: 1987. When Hemsec SIPs are used as part of a through-wall build up they pass the requirements of BS 476-21 fire resistance of load-bearing walls and have achieved up to 75 minutes fire rating. Non-Load bearing walls can achieve up to a 90 minute fire rating (BS 476-2:1987).

Acoustics:

Please refer to Hemsec SIPs BBA certificate, Section 12 – Resistance to Airborne Sound.

Jointing:

Materials used to join panels should be selected to meet the structural requirements of the construction and be approved by the projects’ Structural Engineer. Standard SIP panel splines provide low air leakage and enhance thermal performance. Solid timber splines should be responsibly sourced, and the suppliers must provide evidence of its sustainability credentials through FSC/ PEFC certification.
