PRODUCT PERFORMANCE

THERMAL
The thermal conductivity of the Sip Build polyurethane core is typically 0.025 W/m.ºK Using the Sip Build panels can provide extremelylow U-values for walls. Depending on detail of construction this can be in the range 0.21 to 0.14 W/m².ºK. For roofs designs can deliver U-values in the range 0.20 to 0.12 W/m².ºK.
Thermal Performance Table


FIRE
Sipinfill panel will meet all the requirements in the
Building Regulations with regard to fire resistance when lined with plasterboard. These requirements are
similar to those for timber frame construction. A single layer will provide 30 minutes rating and a double layer 60 minutes rating. SIP Build can provide standard construction details and results from independent fire tests.


AIR TIGHTNESS
Use of the SIP Build SIPs panel and jointing system can create a near airtight structure that will exceed the
requirements in the new Building Regulations and can
be designed to 0.95 air changes / hour @ 50 Pa
(1m3/h/m2). Such is the effectiveness of the system
that positive ventilation methods should be considered.
At the same time positive ventilation systems can be
linked to heat recovery that can save energy costs.
SIP Build will be pleased to advise.


ACOUSTIC
Typical acoustic performance circa -45 dB rating.


STRUCTURAL PERFORMANCE
Tests on a 4m single span of 150mm thickness
SIP Build SIPs showed ultimate failure at 18KN/m².
Assuming serviceability deflection at a nominal L/200
the the load for the 4m span was 2kN/m². It is therefore
the deflection of the panel that routinely becomes the
limiting factor in the design process. This increases
user confidence knowing that safe working loads are
well in excess of standard deflection limits.SIPs form a light and strong structureExcellent for in-plane loads
SIPs buildings actually behave as thin shell structures,
dispersing point loads throughout the entire surface area.

SIP Build panels have been subjected to a number of
testing procedures. These include loading the panels
with a uniformly distributed load (‘U.D.L’) to measure
strength and deflection between two supports, axial
loads centrally and eccentrically placed, racking loads
and shear and bending loads on the panel joints.
The strength of the joints between the individual panelsis such that panels can be used to span over openingsand be supported by the panels each side.Its easy toincorporate additional timber to support localizedconcentration of loading.Routinely this is done at thejoints in the panels. However, with careful detailing,much of this can be avoided.SIP Build will be happy to provide guidance tostructural designers.
