230 mm can be achieved when using a ren- dered system, giving a U-value of 0.20 W/mk2
a brick outer skin with a thickness of less than 300 mm. It is estimated that on a traditional 1,400 ft2 100 ft2
house using SIPs could result in up to more internal space.
A dimensionally stable product, it moves very
little once built meaning that the usual snagging issues of a timber frame are removed. The offsite production allows for accurately constructed, high quality buildings with known performance that is less prone to weather disruption and ‘Friday afternoon’ quality issues. Knowing costs before the work begins and
having a programme that is unlikely to be affected by the weather means budgeting and programming of sites can be more accurate and costly preliminaries reduced. The use of one contractor pulling together a
number of trades also helps the management of small to medium sites, which in turns allows the developer’s management team to spend time on other areas. Major features such as doors and windows
can all be procured in advance, safe in the knowledge that the offsite construction and accuracy onsite will allow the site to be secured faster. A major benefit of this is also that the inter- nal works can progress at the same time as the external works. The removal of brickwork from the critical path during the wet winter period (or even summer!) is also a benefit to many. For tight and contentious sites the use of a SIP
structure can reduce transport movement to site – therefore the muck and debris strewn on sur- rounding roads is limited due to a reduced num- ber of deliveries. The system also produces less site waste which will ultimately mean less skips on site – often a hidden cost. One project recently saw SBUK complete a
five unit development within seven weeks, on programme and with virtually no snagging while the country saw some of the worst winter rain experienced in years. The site at times was a quagmire but SBUK’s site movements were coordinated with the management team to min- imise disruption to the site, the locals and its own works. At completion, this site would have been a little above ground floor level had it
Felmoor Park receives Premium Protection
The Scandinavian log cabins and lodges at the picturesque Felmoor Park in Northumberland have been given a striking new finish thanks to Remmers. Remmers HK Stain was selected to provide not only effective weather protection but protection against blue stain, rot and insects.

leaving it fully breathable and as it doesn’t flake or peel. Available in a wide range of traditional colours or the alternative ‘Grey Protect’ range.

been built traditionally. In summary the only thing that is currently
holding developers and consumers back from using this system are the traditional misconcep- tions and belief that because we have always done it that way, it must be right. Construction is the only industry that embraces innovation and new products with disdain and caution beyond all reason! SIPs have been around for decades now and
the market finally appears to be waking up to the benefits and speed that the system brings. As with all great solutions, once enough people discover and start using it, SIPs can become the norm.
