Dual Roof Anti
Condensation System

Overview
In today’s environment of conservation, the
reduction of energy consumption and the importance of environmentally friendly
products cannot be overlooked. The savings and benefits in supplying natural
daylight is very much an effective tool in preventing energy consumption. Heat
penetration however can diminish the benefits derived from natural daylight.
This is where the Ampelite Dual Roof Anti
Condensation System provides a solution. The system provides natural daylight
whilst also ensuring minimum transmission of heat.
Sports stadiums and multi-purpose halls will benefit
the most from Ampelite’s Dual Roof Anti Condensation System. Condensation
forming on the skylight panel due to internal warm moist air meeting with a cold
skylight surface is fully eliminated. Condensation will form on any surface
having a temperature below the dew point temperature of the air under
consideration. The relative humidity (amount of water vapour in the atmosphere)
within a sports stadium can rapidly change with large numbers of occupants. At
normal ventilation rates, a body of air will absorb moisture from the occupants
at the rate of 50-60g/person/hour. This may result in a moisture content
exceeding that of the external air by about 2g/kg of dry air. Therefore the
risk of condensation forming on cool surfaces increases dramatically.
The Ampelite Dual Roof Anti Condensation System uses
the fundamental principals of double-glazing to create a simple yet functional
skylight system. Overseas countries with colder climates use complicated double
glazed skylights to prevent heat loss. The Ampelite Dual Roof Anti Condensation
System 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 saving and
environmental benefit for years to come.
Independent engineers’ testing has established the
benefits of the Ampelite Dual Anti Condensation System. When compared to other
sky lighting products, the Ampelite Dual Roof Anti Condensation System displays
superior thermal properties. Please refer to the table below.
