agRoc SIPS (structural insulated panel system) is New Zealand’s highest quality building system by a wide margin. A bold statement granted, but easy to verify. MagRoc Structural Insulated Panel System are highly insulated with low thermal bridging, airtight and contain no organic material that is vulnerable to moisture degradation.
Insulated panels are laminated using MagRoc magnesium oxide board on either side of fire retardant rigid foam insulation to engineering tolerances in a factory environment, assembled into wall, roof and floor sections complete with services within walls, and when delivered to site and erected you can immediately install windows and roofing and you are closed in, ready for finishing. This can happen in a matter of days from having your floor or slab down. Using a fraction of the manpower by comparison with conventional construction, saving weeks of construction time.
What Are SIPS?
MagRoc SIPS are Structural Insulated Panel System, an extremely strong, well insulated and economical construction system. The panels can be used to construct floors, walls and roofs delivering the highest performance homes available on the New Zealand market.
MagRoc SIPS replace traditional timber framing with interconnecting composite panels that are manufactured in New Zealand from a combination of MagRoc magnesium oxide board and rigid foam insulation. The MagRoc board is a totally inert fibre reenforced mineral cement board that is impervious to fire, water and pests while being hypoallergenic and containing no chemical binders.
Why Choose SIPS?
MagRoc SIP structures simply work better than conventional timber framed buildings in almost every way. They have better insulation, airtightness, strength, fire and mould resistance.
SIP panels have a core of rigid foam meaning they are incredibly well insulated and because all connection joints are foam sealed for airtightness the thermal performance of a SIP home is significantly better than timber framing – whether you want to keep warm in the winter or cool in the summer.
What does a SIP house look like?
Any house you like!
Unlike some modular or prefabricated construction systems which dictate what your home must look like MagRoc SIPS can be used to turn any design into a high performance home.
Want a classic villa with a high pitched roof and gable ends? Not a problem. How about a Scandinavian style modernist house with a flat roof? MagRoc SIPS can handle that too.
If you can imagine it then you can probably build it with MagRoc SIPS!
How about council consents?
MagRoc SIPS have received CodeMark certification meaning the system has been rigorously tested for New Zealand conditions and meets the requirements of the New Zealand building code. This is an unchallengeable assurance meaning there will be no additional delays in your consenting process.
(this applies to all elements of your design that fit within the constraints of the MagRoc CodeMark. Any SED – specific engineering design – will require additional input from an engineer)
All Magroc SIP panels – floors, walls and roofs – are available in three standard sizes (height x width)
- 2440mm x 1200mm
- 2745mm x 1200mm
- 3050mm x 1200mm
