Heat-proof block stone buildings makes life more comfortable
By Surekha GALAGODA
Sembakutti Arachchige Ranjith Canute Tissa Silva who hails from
Katana, a mechanical engineer by profession has a eye for detail and
helps people to make their lives more comfortable and healthy.
This led him to manufacture a cement block which does not retain heat
due to the unique way it has been shaped.
A person who looks at the cement block manufactured by Silva may
wonder what the difference is? The answer is simple, it does not retain
the heat as there are holes in the block.
He said that normally a house built using cement blocks gets warm
during the day as the blocks get heated. But my blocks don’t get warm as
the air is circulated due to the holes in the block.
Therefore, people living in houses built using the cement blocks
turned out by me will save on electricity and thereby become environment
friendly in the process.

He said that as the house is cool people will not need fans or
airconditioners and this would save electricity. Silva says that
electricity consumption can be reduced by more than half in these
Silva says that his invention is the world’s first heat-proof
cellular block stone and he is planning to market it. He said that he
has received all the certificates from the relevant institutions and is
ready to go for commercial production.
The Sri Lanka Inventors’ Commission has promised to promote the
product and also provide some funds.
Silva said that plans are under way to open a factory in Bokundara,
Piliyandala to produce the blocks on a commercial scale. It will be
known as High Tech.
The only delay is the funding which he is expecting from some private
In 1998 he found that a vehicle could be operated using wind power
but I could not produce it on a commercial scale due to lack of funds
An old boy of Marie Stella College, Negombo, he said that he has
worked in the best companies around the world and in Sri Lanka as well.
One of his brothers is an accountant while the other brother is a
Silva proffered his thanks to all those who supported him including
the Sri Lanka Inventors’ Commission.
