Wonderglas GC
Overview
Greenhouse growers often believe that it is easier to grow moss
on top of a fibreglass greenhouse than plants inside it! “Fibre-show” has
plagued the perceptions of fibreglass for years. Ampelite’s revolutionary
Wonderglas GC however, is set to change how the world sees fibreglass.
Wonderglas GC features a unique gel coating which prevents fibre-show
and maintains high levels of light transmission for many years.

Testimony
“I first experimented with Wonderglas GC in 1995. To date, I have
been more than satisfied with the product living up to claims that the “gel
coating” would prevent the sheet from eroding, whilst maintaining light
transmission over a long period of time. We now have over 3 acres of Wonderglas
GC on a range of buildings from propagation sheds to growing sheds.”

Available Profiles
All current profiles such as
Corrugated, Trimdek, and
most superseded profiles are available. Ampelite can also supply the unique
“greenhouse profile”. This profile features shallow, steep ribs to maximise
spanning capacity, whilst minimising light transmission loss through shade. The
unique connection between sheets is also designed to maximise light transmission
through minimal overlap on side ribs.
Custom profiles are often produced for applications such as
growing trays.

Spanning
Wonderglas GC features excellent spanning capabilities, unmatched
by other translucent materials such as glass, polythene film and profiled
polycarbonate.

The above spans are recommended for wind loads up to 1 kPa. For
high wind or cyclonic areas, please contact Ampelite.
Thermal
Insulation
Wonderglas GC has a K-Value of 5.8 W/m2.K. When
incorporated into the Dual Roof system, this reduces to 2.0 W/m2.K –
the lowest of any greenhouse cladding material!
Wonderglas GC is compatible with anti-condensation coatings and
white wash.
Light
Transmission
Ampelite’s range of Wonderglas GC sheeting for greenhouses
includes special additives to aid light diffusion. This reduces shaded areas
within the greenhouse and minimises plant damage associated with sun burn.
For applications where maximum light transmission is not
favourable, Ampelite can manufacture Wonderglas GC sheeting with customised
light transmission figures.

Ampelite’s unique Dual Roof System combines the excellent
spanning and solar optical properties of Wonderglas GC, with thermal insulation
unmatched by other cladding materials.
Light transmission: 82%
K-Value: 2.0 W/m2.K
The Ampelite Dual Roof
System uses the fundamental principals of double-glazing to create a simple, yet
functional skylight system. Dual Roof has specifically been designed for the
Australian climate, with simplicity and ease of installation a high priority.
Whilst the system is not unique in theory, in practice it provides a long-term

Cost-effective alternative
Ampelite’s Grow Tray is an innovative new product that overcomes
many of the shortcomings of other alternatives. The excellent spanning
capabilities and corrosion resistance make it a long-term alternative to metal
trays.
Some Grow Trays utilise rotationally molded plastics that are
both costly and difficult to customise. Ampelite’s Grow Tray is easily
customised for individual applications and can be installed on any basic
roll-tray system for maximum efficiency.
