FAQ's
Frequently Asked Questions.
How do SIPs react to fire?
SIPs have passed every Standard fire test that is required. A key element of fire safety is protection of the SIPs and any other underlying structure with thermal barriers like gypsum wallboard. One 12.5mm Fire Plasterboard on the Hemsec Sip panel can achieve 60mins fire rating. Another reason to use the Hemsec SIP system less plasterboard!!
How do SIPs save so much labour?
SIPs are manufactured efficiently and to high quality and accuracy in SIP Build UK factory. They are transported direct to site in much larger dimensional sizes than other building materials. Erection is fast and easy using SIP Build UK spline jointing system that rigidly locks the panels together. The building is weather proof faster and other subcontractors can get a head start on the work that needs to be done.
What are the options for external finishes?
Almost total choice from bricks, natural stone, brick tiles, polymer and cement renders, timber cladding and metal cladding and probably some we haven’t listed!!!!
Who can design SIPs?
Professionals are increasingly aware of SIPs and there should be no problem designing a building from scratch to use SIPs or modifying an existing design. SIP Build UK and its partner companies will be happy to provide technical advice and support to professionals and self-builders.
Is planning a problem with SIPs?
SIPs is an accepted building technology and will not cause problems with planning approval. In the same way a well detailed and engineered SIPs design will not raise difficulties with building control. SIPBuild UK is always available to give advice.
Are SIPs houses covered by warranty schemes?
All the companies offering warranty schemes accept SIPs construction. A well-designed and constructed SIPs house should have a life expectancy equal to present types of construction. In addition, most lenders are able to offer mortgages on SIPs houses.
What foundation should be used?
Any construction can be used but the tolerance to level must be +/- 5mm to ensure the most efficient erection of the SIPs panels.
What is the best heating system for a SIPs house?
Any conventional heating system can be used although SIPS are also ideally suited for more innovative and energy efficient solutions. Your ventilation strategy will have a big impact on your heating decision but we would generally advise a mechanical vented heat recovery system be installed (MVHR).
Can services be installed in the Sip Walls?
No. The sip panel is a thermally efficient airtight product that is better without services running through. We would always recommend the use of a counter batten to create a service void for the services to be positioned in.
Why are sips so popular now?
With higher energy costs and increased performance required to meet Building regulation requirements Sips are seen as the most cost effective way to achieve these. Thermally efficient, airtight, fast to erect, lightweight and made offsite in a factory as a modern method of construction.
Will I need to use MVHR?
All new homes need a supply of fresh air not just for the health and comfort of the occupants, but also to control condensation, remove pollutants and to ensure efficient operation of various appliances. We do recommend the use of MVHR but this will need to be discussed with main designer of the building.
