Structural Insulated Panels (SIPs)
What are SIPs?
SIPs are structural insulated panels used to construct
buildings. SIPs have been used extensively in the USA over the
past 50 years but are now becoming a popular choice in the UK for timber-based construction.
SIPs are environmentally friendly and ecologically sound.
SIPs are the innovative building construction method of the twenty
first century allowing the rapid deployment of buildings for domestic
and commercial use.
Schools, hotels and retail developments are realising the benefits SIPs can bring
to a project, we are providing SIP solutions for buildings reducing or in some cases
eliminating the need for a structural frame using the inherent strengths a SIP can
provide.
A SIP provides an ideal substrate for overfixing rainscreens (see
Architectural Cladding for more information). This can be done on site in
the traditional manner or off site providing quicker system build techniques. These
Modern Methods of Construction (MMC) solutions are becoming increasingly popular
on time sensitive projects.
How are SIPs made?
A basic SIPs panel is made from Orientated Strand Board (OSB) facing
boards with a CFC free/ ODP zero closed cell Polyurethane core. SIPs
can be used to construct the floor, walls and roof of a building enabling uniform
detailing at interfaces providing continuity of insulation and minimal air leakage.
Historically sandwich panels have been used in the UK mainly for buildings with
high thermal requirements. At McVeigh Insulations we have been using this technology
for the construction of Cold Stores, Real Snow Ski Slopes
and Ice Climbing Walls for many years (see photograph of 1940s cold stores built by McVeigh Insulations
using early SIPs technology). As the Building Regulations are demanding more energy
efficient structures the sandwich panel solution is becoming more favourable.
Why Choose SIPs? Benefits of SIPs
SIPs are used all over the world because of their superior
strength and quality build. Homes and commercial buildings
that use this innovative technology have survived hurricanes, earthquakes and tornados,
when other buildings around have not. In the UK SIPs are more than
capable of withstanding climate extremes as well as maintaining their strength throughout
the years and providing a safe and secure living environment.
Benefits of SIPs
- Environmentally Friendly
SIP timbers are used from a sustainable source and are made with an ODP zero
insulated core.
- Speed
Quick installation is made possible by using large pre-fabricated units. Envelope
completion allows following trades to start earlier.
- Strong and Lightweight
Rationalise foundation design. Nature of the panels means open spaces can be
constructed without the need for additional framing.
- Rooms within Roofs
Fully utilise the roof space of buildings with the long span capabilities of
SIPs.
- Defects and Shrinkage
Buildings made in factory conditions helps reduce defects. Comparable to timber
frame construction shrinkage and subsequent making good is minimal.
- Minimal Waste & Maximum Recyclability
All panels cut to length and apertures formed in the factory result in minimal
site waste. Off cuts from engineered panels in our workshop can be recycled.
- Keep your energy for longer
Highly insulated buildings with minimal thermal bridging air leakage.
- External finishes
Many external finishes can be applied to SIPs. From render, rainscreen and
weatherboards to brick slips, tiles or conventional brick outer skin. All can be
applied off the critical path of the overall project duration.
How can I use SIPs in my building project?
SIPs can be bought in kits that can be customised to a particular customer's needs.
