SIPTEC
Structural
Insulated Panels
SIPTEC 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.
Siptec 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.
Siptec 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
Siptec
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.
The Siptec Eco-Tec Panel facing can accept
the direct application of cement or polymer renders and
plaster internal finishes.

Siptec Sips
are made by pressure injection, a process
that produces a consistent high quality product and
virtually eradicates operator / manufacturing errors,
delamination of Siptec Sips is just not an issue.
Siptec
Systems
maintain an
R-value of six per 25 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.
Siptec
Sips
are made
30, 60 & 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.
Siptec 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.
Siptec 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 / train you or your
builder on site how to proceed, this has proven to be the
most successful cost effective procedure / method of building
with Sips.
Environmental Performance
Sips are
resource efficient, they
use less wood than conventional framing and the facings
provide an efficient use of wood fiber 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 Siptec House gives significant
savings on building shell cost. |
Thermal Efficiency
is
maintained throughout 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 fiber products.
Energy Efficiency
Siptec 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 Siptec 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 fiber batts or cellulose fiber 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 Siptec 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 Siptec 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.
Siptec
Finishes
Any type of wall and roof finish can be
applied to Siptec building shells, concrete tile, slates,
bricks, render, or any type of cladding material.
