SIPit-FR
Magnesium Oxide SIPS panels (MGO) represent a significant advancement in the field of structural insulated panels, offering a superior fire rating compared to traditional fiber cement and OSB SIPs.
​
The SIPit-FR panels adaptability ensures that MGO panels meet the demands of diverse building environments while maintaining structural integrity.
​
Modern construction prioritises sustainability and 'clean' internal environment, and the SIPit-FR stands out as a healthy choice. They contain no organic solvents, heavy metals, asbestos, oils, or other toxic ingredients and are classified as a “Green Building Material.” Furthermore, MGO does not support black mold growth and exhibits high resistance to moisture absorption.
​
The strength and durability of MGO also contribute to its suitability for extreme conditions; it is impact-resistant and designed to withstand extreme weather conditions. ​
​
The SIPit-FR offers superior loading capacity, fire ratings, and acoustic performance.
​​
It is essential to note that not all MGO board products are created equal. and we use only the finest magnesium oxide materials available in the market today. This commitment ensures that our customers receive products that meet rigorous quality standards while delivering exceptional performance across multiple applications.
Carbon Capture
Section Subtitle
Magnesium Oxide (MgO) boards have a unique characteristic that can positively impact their carbon footprint: carbon capture during manufacturing and throughout their lifecycle. This aspect is often not accounted for in traditional comparisons with materials like OSB3.
Carbon Capture in MgO Manufacturing:
1. COâ‚‚ Absorption During Curing:
MgO boards are typically produced using magnesium carbonate, which is calcined to create magnesium oxide.
During curing, MgO reacts with atmospheric COâ‚‚ to form magnesium carbonate again, effectively absorbing COâ‚‚ from the environment. This process is called carbonation.
2. Net Reduction:
The amount of COâ‚‚ absorbed can significantly offset the COâ‚‚ emitted during production. Depending on the manufacturing process, MgO boards can potentially capture up to 40-50% of their embodied carbon emissions during curing.
3. Alternative Production Methods:
Some manufacturers are experimenting with low-carbon production techniques, including renewable energy use and alternative raw materials, which can further reduce the embodied carbon of MgO boards.
Carbon Capture During the Lifecycle:
1. On-Going Carbonation:
Even after installation, MgO boards continue to absorb COâ‚‚ over their lifecycle, as they are exposed to air and humidity in their environment.
Research suggests that MgO boards can absorb an additional 10-30% of their weight in COâ‚‚ over decades of use.
2. End-of-Life Recycling:
When MgO boards are recycled or crushed, the exposed surfaces accelerate carbonation, capturing even more COâ‚‚.
Comparison to OSB3 with Carbon Capture Considered:
1. Embodied Carbon of OSB3:
OSB3 is made from wood, which sequesters carbon during its growth. However, when considering processing, adhesives, and treatments, OSB3 typically has an embodied carbon of 2-10 kg COâ‚‚e/m², depending on sourcing and manufacturing methods.
2. Embodied Carbon of MgO:
Without considering carbonation, the embodied carbon of MgO boards is higher, ranging from 10-20 kg COâ‚‚e/m², mainly due to energy-intensive calcination and transportation.
3. Impact of Carbonation:
Including carbon capture during curing and its lifecycle, the net embodied carbon of MgO can drop significantly. In some cases, MgO boards may achieve a neutral or even negative carbon footprint, depending on manufacturing and installation conditions.
Additional Considerations:
Durability: MgO boards often last longer than OSB3, reducing the need for replacements and lowering the overall environmental impact over a building's lifetime.
Recyclability: MgO is fully recyclable, which further supports a circular economy and reduces waste.
Transportation Impact: Locally sourced MgO would significantly reduce emissions compared to imports, improving its carbon reduction potential.
