Solar Star Roof Ventilation System
When we recommend this product
A hot roof acts like a giant radiator, transferring heat into your living spaces, sending both utility bills and temperatures soaring. In colder climates, heat build-up in a roof causes condensation in colder climates in the roof cavity. Roof ventilation is a great passive way to assist your home cool down, with minimal or no energy use and can complement other cooling systems such as evaporative and air conditioning systems.
Ventilate the roof space where possible to allow built up heat to dissipate. Convective air movement relies on hot air rising and exiting at the highest point. Clerestory windows, spinnaway roof ventilators, and vented ridges, eaves and ceilings will allow heat to exit the building in nil breeze situations through convection.
- Reduces heat build up.
- Reduces air conditioning costs.
Many of today's houses have insufficient ventilation and air exchange. This causes high humidity levels from everyday activities. This moisture migrates through the ceiling towards the roof where it comes in contact with the cold structure. Here, ice and frost form, causing damage to your roof structure. Additionally, moisture can saturate insulation, promote fungal decay and plywood delaminating.
How to get the most from this product
Naturally having good levels of ceiling insulation will slow the transfer of heat from the roof cavity into your home. Insulation will also keep the warm air in your living spaces during winter. To increase the capacity of your roof to reflect summer heat, products like Air-Cell under the tin or tiles provides excellent protection. Other products like Thermalite can be painted onto the exterior of your roof or walls to reflect summer heat.
