Overview

HySSIL has developed a range of Geopolymer roof tiles which are; lighter, stronger and more durable than conventional concrete roof tiles. The key ingredient in HySSIL’s Geopolymer roof tiles, fly ash, in lieu of Ordinary Portland Cement, provides a significant reduction in CO ₂ emissions (approx. 60%). HySSIL Geopolymer roof tiles can be manufactured using existing concrete roof tile manufacturing machinery.

 

Geopolymer Lightweight Roof Tiles

HySSIL and a major US concrete roof tile manufacturer and have been working together since February 2009 to develop a lightweight Geopolymer roof tile for the North American housing market in conjunction with HySSIL’s research and development partner, CSIRO. 

 

Uses and Applications

The potential for this product is not only in the existing lightweight roof tile market but also, at the weights proposed, as a replacement for lighter malthoid and timber shingle roofing systems all without the need to strengthen the roof structure. This is a major market in fire prone areas such as California.

 

Features and Benefits

The key advantages of Geopolymer roof tiles compared to Ordinary Portland Cement (OPC) roof tiles are:

• Lighter and stronger
• Better resistance to the elements
• 60% less greenhouse gas (CO ₂ ) emission from component materials

 

 

 

 

 

 

Geopolymer Conventional weight Roof Tiles

The major US concrete roof tile manufacturer and HySSIL have agreed to commence working together to develop a conventional weight Geopolymer roof tile for the North American housing market in conjunction with HySSIL’s research and development partner, CSIRO.

While these tiles are likely to be lighter than cement based roof tiles due to the higher strength of the Geopolymer matrix, the main economic benefit will come from the sales premium that can be extracted on the basis of the significantly greener materials used in their manufacture.
