Structural Insulated Panels SIPs are also known as structural insulated
panels or SIP systems; they are a material and labour-saving alternative to
traditional timber framing and masonry construction. The insulation within
the panels is continuous and is not bridged by timber studs. Structural
insulated panels have been in use for more than 50 years, they offer an
energy efficient building system that is simple to build with and thus
substantially reduces on-site labour time and cost.
SIPs can be used as structural walls (including foundation walls), floors
and roofs, either independently or in combination. SIPs can also be used
with timber and steel frame buildings. The greatest savings in time, energy,
and materials used, is achieved when Siptec panels are used for the entire
structure.
SIPs offer excellent structural performance because they are sheathed on
both faces and the sheathing is fully adhered across their entire surfaces,
they behave as an integral composite and resist wind forces and building
loadings far better than timber framing.
The Siphouse Structural Insulated Panel has a PU foam core, faced with
oriented strand board, OSB or Cement Particle Board, CPB. CPB panel facings
are a class 0 building board with superior fire, acoustic and weathering
qualities to other facings. The direct application of rendered finishes is
acceptable on Siptec CPB facings, CPB facings can stand freeze thaw
weathering even without painting. We do not recommend the direct application
of polymer renders to OSB Facings, we believe long term this practice will
create dry rot in the facing.
Siphouse SIPs are made by pressure injection, a process that produces a
consistent high quality product and virtually eradicates operator /
manufacturing errors, de-lamination of Siphouse Sips is just not an issue.
SIP Systems maintain an R-value of six per25 mm thickness, compared with EPS
at four per 25mm. The facings distribute and carry the structural loading
while the bonded foam core provides insulation and keeps the two skins
aligned.
Siphouse Sips are made 30, 60, 90 & 120 cms wide x 2.4, 2.7 & 3 mtrs. Roof
sips are made up to 6 mtrs long and 125,150 & 200 mm thick, there are
several methods of joining Sips depending on the application.
SIP Buildings go up fast and give a weather tight shell early in the
construction process because Sips incorporate both the structural frame and
thermal insulation in a single step, supervision and co-ordination of trades
are simplified. Siphouse offer a full design and engineering service.
Sipthouse can custom produce panels (RTA Panels) by pre-cutting rough
openings, edges, angles, and other complex shapes, these are then delivered
to site ready for installation, or the company can show you or your builder
on site how to proceed.
Environmental Performance Sips are resource efficient, they use less wood
than conventional framing and the facings provide an efficient use of wood
fibre while the foam core material has very high insulation values. Although
the foam core comes from a non-renewable resource, it is an efficient use of
this resource, one litre of an oil refining by-product is converted to
create forty cubic litres of PU foam. Overall, Sips are a resource-efficient
building technology with significant energy efficiency and forest
conservation benefits. A Siphouse home gives significant savings On building
shell cost.
Economies in Time & Material A SIP demonstration house was built at the
University of Oregon, they calculated that using SIPs they saved 2,720 board
feet of wood that’s nearly 50% of the framing timber for conventional
construction and the house required 161 fewer man-hours to build.
Thermal Efficiency is maintained through out the building’s life, the closed
cell foam does not allow moisture ingress to degrade the insulation
performance as occurs with mineral wools and blown cellulose fibre products.
Energy Efficiency Siphouse homes are very energy efficient when sips are
used throughout the whole building envelope. The insulation is continuous
and Sips allow little air leakage, so a SIP house is generally easier to
make airtight than a conventional house. A house built with Siphouse SIPs
will give energy savings of 40% - 60% compared to a timber-frame house of
equal size and Insulation U value. This is largely due to the more efficient
insulation that eliminates any potential for thermo siphoning or wind
washing which can be a problem with glass fibre batts or cellulose fibre
insulation, the panels themselves provide the required air and vapour
barrier however, to ensure a tight (draft free) home, the joints at the
panel to floor, panel to panel, panel to roof, and at penetrations must be
sealed with Siphouse adhesive.
The SipHouse ® roof structure encloses a large volume while creating
interesting living spaces, because the panels do not have open cavities,
they require different approaches to plumbing and electrical installations
Siphouse supply client’s with information on these kinds of details. Sips
faced with 12.5mm of plasterboard meet the UK fire regulations. The UK
government is actively promoting the use of Sip Building and whilst
officials are not necessarily familiar with sips they have generally been
receptive to their use but will ask for a professional engineer to verify
the structural performance. Siptec can supply this service.
Finishes: Any type of conventional finish can be applied to Siphouse Sips. |
