We are now experiencing some of the warmest summers on record which
are expected to continue and increase in the future. Macrolux have
developed a new technologically advanced - Polycarbonate sheet to
reduce excessive heat build up in conservatories and delay the time
for achieving the maximum temperature. |
The revolutionary Macrolux ‘ATHERMIC HEATSHIELD’ is a
special reflective finish which is co-extruded into the upper surface
of Macrolux Multiwall polycarbonate sheets. To further reduce internal
glare, the underside is Opal finish and also gives a bright internal
appearance. Conservatories, especially those with clear roofs
experience an excessive heat build up and are limited to installing
roof vents and/or blinds - options which can potentially exceed a
customer’s budget and in many instances detract from the beauty of the
conservatory. |
Macrolux ATHERMIC
HEATSHIELD has been independently tested by TNO Centre, Netherlands
and comparisons made with standard 16mm triplewall polycarbonate
sheets. These independent tests confirm that by utilising ATHERMIC
HEATSHIELD the total heat/solar energy transmission penetrating
through the sheet can be significantly reduced.

ATHERMIC HEATSHIELD is available on the extensive range of Macrolux
products (up to 2100 mm wide) including Twinwall, Triplewall and the
new 5 Wall, ‘M’ Structure and ‘X’ Structure Range. |
Macrolux ATHERMIC HEATSHIELD has a UV absorber co-extruded onto the
outer surface of the sheet. This forms a barrier against UV radiation,
and ensures exceptional resistance to ageing without affecting the
sheet’s mechanical properties or impact strength. |
Although light in weight all Macrolux polycarbonate sheet is approx
200 times stronger than glass and virtually unbreakable when subjected
to heavy storms, hailstones or falls of ice and snow. |

not emit poisonous toxic gasses and complies with most European
standards, including a Class 1 fire rating to BS476 part 7 and BS476
part 6 and can be recommended for use as a Class ‘O’ building
material. |
