SIGA. Your answer for creating an air and weather tight building envelope.


We strive for a world of zero energy loss buildings.

SIGA develops and produces high-performance products free of toxins that are resistant to aging and provide an airtight seal for buildings of all types.

  • High energy losses today

There are many small gaps or leaks in a building envelope, which allows heat and cooled air to constantly escape.

  • Major heating requirements

Powerful heating systems are required to maintain a room temperature at 68°F in winter because of constant heat escaping.

  • Major cooling requirements

Over the next 30 years, 10 air conditioning units will be purchased every second globally. Powerful air conditioning systems are required to keep spaces at a comfortable 75°F because of constant cool air escaping.

  • Leaking buildings intensify climate change

Inefficient buildings create high CO2 emissions, which intensifies the greenhouse effect and accelerates global warming and the threat of climate change.

4 major advantages of airtight buildings

  • Greater living comfort

Live without drafts. Airtight buildings keep heat and cold outside, as well as traffic noise and air pollution.

  • Save money, protect the climate

Energy consumption for heating and cooling of an airtight building is significantly lower than traditional structures, and as a result, reduces climate-damaging CO2 emissions.

  • Preserve value

Airtight buildings are protected from wind, rain, drifting snow, insects and building damage caused by condensation and mold.

  • Active house feasible

The low energy consumption of an airtight building facilitates self-sufficiency with renewable energy. That’s how easy it is to turn a building into an active building.
