Patented active / passive Coldins cooling insulation

A revolutionary Finnish innovation to slow down global warming


  • 37% of all global CO2 emissions stem from construction and use of buildings.
  • The use of air conditioners and electric fans account for 10% of all global electricity consumption today.
  • 3,7 billion people, or 48% of the global population, live in warm areas where the Coldins innovation potential is found.
  • There are approximately 2 billion buildings worldwide. There is a need for 12.000 new buildings every day, anr the need is increasing with population growth.
  • The global need for renovating existing buildings is ca 83.000 buildings per day.
  • The global insulation market is expected to grow from euro 58 billion in 2021 to 103 billion in 2030.

Our global challenge

Areas in 🔴 are heavily affected by global warming and are also the home for 48% of the world population.

Climate change and population growth necessitates the need for novel solutions to improve energy efficiency and living comfort.

Coldings patented active / passive cooling insulation provides cooler living conditions and increased comfort for the inhabitants.

Patented insulation system that allows warm air flow only in one direction.

During daytime the insulation
keeps heat out.

At night the insulation allows heat
to flow out, cooling the interiors.

Challenges with traditional
insulation in warm climates

  • After a hot day, the buildings with traditional insulation do not cool down during night, because the insulation prevents the heat flow out.
  • For example, with the outdoor temperature 35°C during day and 20°C during night, the indoor temperature can still be 30°C in the morning.
  • Additional mechanical systems are required to satisfy the increased cooling demand.
  • The solutions are expensive to purchase and operate.
  • They cause unnecessary energy demand and environmental impacts.

Benefits of the
Coldins system

Automatic active/passive cooling

  • Improves cooling while maintaining insulation from exterior heat
  • Improves living conditions due to global warming
  • Increases living comfort without power consumption
  • Can be used alongside active cooling solutions like ventilation or air conditioning

Environmental considerations

  • Partially hollow panels reduces material consumption
  • Decreases environmental impact by shipping of lighter panels
  • Reduces cooling cost by adding fully automatic active / passive Coldins insulation

Ease of use

  • Current insulation materials can be used
  • Cost-effective: less raw
    material compared to
    existing insulations
  • Does not change means of installing insulation


We are creating a method to modify the current insulators; with the new solution, the cooling of buildings is simplified and less expensive, while also saving energy and making a major international environmental act.
