  • SIPs BUILDINGS are AIRTIGHT. Good practice is to use HRV or ERV equipment.

    Building tight is right. Buildings can never be to tight. A tight building eliminates to the minimum the air changes and drafts, enhancing comfort and positive impact on your energy bills. However airtight buildings can be under ventilated. SIPs buildings provide airtight enclosures. SIPs components are straighter and flatter than conventional timber frame building components. The tolerances for SIP construction are more precise. The joints are fewer and smaller. The windows are manufactured in controlled environments and only dropped in on site. We use glue and sealants to reduce the number of gaps and lower the air change. The lower the air change, the less the dilution of internal pollutants such as moisture (from people, soil and appliances), formaldehyde (from particle boards, fiberglass insulation, kitchen joinery and bathroom cabinets) and carbon dioxide (from people). Formaldehyde and other emissions can be harmful. It is best to lower the VOCs used within the building and make sure the SIPs enclosure achieves low airtight levels. As air changes go down, interior moisture levels rise causing condensation problems on windows where the surface is cold, mould on walls, dust mites in carpets and decay in wall cavities and roof areas.

  • EPS FLAME RETARDANT to INHIBIT FIRE OCCURRENCE on all EVISSA SIPs

    Flame retardants (FRs) play a crucial role in protecting homes, hospitals, schools and other buildings from the life threatening consequences of fire. In order to reduce the risk of fires and meet building and consumer protection codes, FRs are incorporated into many building and commercial products to accomplish one or more of the following functions: Raise the ignition temperature and the burning rate Reduce flame spread and the smoke generation
