BIO PLUS POINTS WITH BRETT MARTIN
Brett Martin says it is set to reduce the
carbon footprint of buildings around the
world with a remarkable new Polycarbonate
glazing product largely based on bio-circular
attributed material, such as used cooking oil,
produced in an ISCC Plus certified mass
balanced approach.
Called Marlon BioPlus, the new sheet offers a
major carbon footprint reduction by cutting the use
of fossil-based material by 70%. This raw material
delivers an 84% decrease in carbon emissions,
and in addition Brett Martin achieves further
reductions in carbon by producing the sheet using
100% renewable energy, generated at its own site.
Marlon BioPlus has already achieved International
Sustainability & Carbon accreditation with ISCC
Plus certification. ISCC PLUS is a globally
recognised sustainability certification program for
bio-based and bio-circular (recycled) raw
materials with a focus on the traceability of raw
materials within the supply chain.
What makes Marlon BioPlus unique is the
combination of this certification and Brett
Martin’s 100% onsite renewable energy which
together represents a huge step towards a zerocarbon
polycarbonate sheet.
This new low carbon alternative retains all the
physical and performance properties of the
company’s other Polycarbonate ranges and will be
available to be specified in any of Brett Martin’s
Marlon polycarbonate multiwall, corrugated or
flat sheets for use in roofs and walls.
Employing over 1,000 people in total and with
sales of £220 million, Brett Martin is already one
of Europe’s largest plastic sheet producers for
the construction industry, and the new range is
expected to create strong demand from a
construction market eager to reduce its
environmental impact.
Brett Martin Director, Paul Martin said: “This
development of this new product reflects the
Brett Martin anticipates strong demand for Marlon BioPlus,
which will be available soon.
newest technology in the plastic industry to
introduce bio-based material. The process,
known as mass-balancing, certifies the input of
the material through the production system,
similar to the way renewable energy enters the
power grid. Importantly, the material is a
recycled source and therefore the bio-based
content does not compete with food production.
“And because the substitution occurs at the earliest
stage of the resin production process, all the visual
and mechanical properties of the finished sheet
remain completely unchanged,” he added.

SLIM SOLUTION FOR INVERTED ROOFS
Kingspan Insulation has launched the OPTIM-R E Inverted Roofing System, the latest evolution in its
innovative vacuum insulation panel (VIP) range, providing a thin solution for challenging
applications. The VIPs feature a protective spray coating, providing a robust finish
which allows easy handling around site.
With a declared thermal conductivity as low as 0.008 W/mK, and a design thermal conductivity as low
as 0.009 W/mK, Kingspan OPTIM-R E offers an excellent solution on new and refurbishment projects where a lack
of construction depth or space is an issue. These include applications where the upstand height is already set or where an
even transition is needed between internal and external spaces.
The system combines OPTIM-R E VIPs with infill strips of the same thickness which can be cut to size to fit around the perimeter of the roof, to fill any
awkward gaps between the VIPs and to allow for penetrations through the roof.
Each project is supported by Kingspan’s dedicated design service, tailoring the solution to ensure the target U-value can be met with the slimmest
possible insulation depth.
Each layout clearly illustrates the size, number and location of the OPTIM-R E VIPs, facilitating a fast, dry installation on site.
The system, manufactured at Kingspan Insulation’s facility in Pembridge, Herefordshire, also provides excellent protection for the waterproof membrane
and is compatible with most green roof systems.
