CEILING AND FLOOR
INSULATION
SUPPLIER SOLUTIONS – GREENSTUF
GreenStuf has developed a range of insulation solutions to meet the increased
insulation requirements
50% previously recycled polyester fibre (from PET
plastic) and are reusable and recyclable at end of life.
THE POWER OF POLYESTER
G
reenStuf 100% polyester insulation is
a powerful product that has helped keep
Kiwis warmer, healthier, and drier all year
round, and there are clear benefits for using it.
For anyone installing them, GreenStuf products
are safe to touch. Being made from 100% polyester
means there’s no nasty itching or scratching. It’s
completely safe and does not require protective
clothing when handling or installing.
However, the benefits don’t stop there, as you can
rest assured that the insulation is built to last. With
a 50-year product durability warranty, no slumping,
and not affected by moisture, this polyester insulation
is perfectly suited for homes all over New Zealand.
On top of this, GreenStuf has been independently
endorsed by Asthma New Zealand and accepted
into its breathe easy programme.
GreenStuf is also environmentally friendly. Its range
of solutions are manufactured using a minimum of
GreenStuf views waste as a resource with potential,
not something to be disposed of. With this in mind,
it operates zero-waste production lines; all product
trimmings and offcuts are reused, and all waste
|material is re-integrated back into production.
TAKEBACK PROGRAMME
GreenStuf strongly supports circularity in the
New Zealand construction sector and gladly accepts
any GreenStuf offcuts and packaging back for
recycling. GreenStuf believes that, as a manufacturer,
it is responsible for understanding the life cycle of its
products and providing a safe end-of-life solution
for its customers. To ensure returned material can
be recycled, the takeback programme requires all
material to be uncontaminated.

THERMAL UNDERFLOOR R2.6 AND R2.9
140MM
To reduce the
heat lost through
floors, GreenStuf
recommends the
use of GreenStuf
Thermal Underfloor
Insulation.
THERMAL CEILING INSULATION R3.4
ROLL FORM 140MM
Under the new H1 energy efficiency clause, in most cases, a single-layer insulation
method will no longer meet the required standards for ceiling insulation. The next
solution to achieving the expected R-value is to use a double layer of insulation.
There has been uncertainty raised by
some about the use of a two-layer
system reducing the R-value that the
insulation is able to achieve. However,
the GreenStuf two-layer system has
been rigorously tested to ensure the
accuracy of the claimed R-value.
To provide an additional level of
assurance, GreenStuf has the first
BRANZ-appraised, double-layer
system currently in the market. With
the double-layer system, you will
be able to achieve a minimum
construction R-value of R6.6 and meet
the H1 requirements for ceilings.
The beauty of a double-layer is that
the two layers can be laid
perpendicular to reduce thermal
bridging. Alternatively, with 90mm
trusses, the bottom layer of insulation
will pillow over to reduce thermal
bridging. Either of these solutions
works.

Additionally, our Thermal Ceiling
Insulation R3.6 Blanket 140mm can
be used in a double-layer system.
This will also allow you to achieve
a minimum construction R-value
of R6.6.
This is designed to
insulate residential and
commercial spaces with
exposed joist floors in
new and existing homes.
