Alexey, city of Odessa

 I have long dreamed about building my own house. So, I decided to search the Internet for the information on technologies and companies that provide construction services. I found Rainbow Ecosystem, learned that they were engaged in eco-construction and wrote to them in chat, requesting a detailed information. Initially I thought that all this was somehow  “not serious”…  straw, clay… but while talking with their manager, I received full information about their technology. I was offered a few house projects, and received calculation of prices for the one I liked. The quality of service was good, as I have been quickly provided the necessary information. Now I’m choosing the best building option for my house, and I will also consider the Rainbow Ecosystem technology.

Sergey, city of Kiev

I have accidentally discovered Rainbow Ecosystem by watching their video in Youtube. To be honest, I was surprised that the traditional Ukrainian building technology, proven for centuries, is still being actively used, while everything looks stylish, modern and even energy-efficient!
This sounded interesting to me, and, after having a conversation with my family, I ordered a project of a house of 120 squares. The Rainbow Ecosystem architects worked out and calculated the whole project in a few days.
Speaking about  the price, it turned to be even a little cheaper than a building from gas concrete. What is more, the heater would not be necessary.
Finally, we have decided to build this and our next houses with this company.

Jurij, AtlandBud SP Z OO, Krakow city

I have been working in a construction company in Poland for 2 years. We mainly build from SIP panels in the Canadian technology. We buy some materials in Ukraine. Three months ago, we learned about Rainbow Ecosystem, contacted Sergey - their representative, and decided that we would work together. Now we also build houses from their eco-blocks. I think that their eco-blocks are a unique building material, because it has a high level of heat preservation, besides, the consumption of electricity in a house made of such blocks, which is 15 kWT / m2 per 1 rock ... most of Ukrainians today can only dream of such a house ... I should add that the production of Rainbow Ecosystem blocks in Ukraine, with the cost of transportation to Poland, is cheaper than building a similar energy-saving house in Poland.

We strongly recommend Rainbow Ecosystem for cooperation to other building companies.

Artem, Zaporozhye city

I am really satisfied with the work of the company. I have been interested in the theme of energy-saving houses for a long time. I wanted to build a big house with minimal expenses for its maintenance. The guys from Rainbow Ecosystem described to me their product and its quality in details. I received a house layout according to all my wishes, along with calculations of the costs of such house. After visiting the production (I was surprised to discover they do not try to keep the production process secret), I realized that this is exactly what I was looking for. I am grateful to the guys for the good work.

12 advantages of building from Rainbow Ecosystem Ekoblocks

1. 100% ecological, healthy microclimate

Our panels for walls, floors, ceilings and roof are made of natural materials only. No harmful fumes, mold or dust. The walls of such house have high vapor permeability, and provide constant natural humidity level of 60%. Eco houses are “easy-breathe”, which improves health and well-being.


2. Maximum thermal insulation, minimum costs for heating and air conditioning.

Warm in winter and cool in summer. Energy consumption of our houses is up to 15 kWh / m2 per year, which is 8 times less than that of the houses built from traditional building materials.

3. Reliability and durability

A double wooden frame with a high safety factor, a wall panel with a width of 1.2 m, a thickness of 0.45 m and a height of 3.0 m withstands a load of 27 tons, which allows construction of buildings up to 3 floors. The panels are covered with moisture resistant clay-lime plaster of 4 cm. Additional protection is also possible with a ventilated facade. Many houses that were built according to this technology in Europe and the US about 100 years ago are still “livable”.


4. The highest fire resistance level among the frame-panel houses

Ekoblocks by Rainbow Ecosystem are protected with clay-lime plaster on both sides. They are able to resist open fire 800-1000 ° C for 1 hour. Their fire resistance rate is REI 60.

5. Protection against rodents

The cellulose is highly compressed inside our panels that the rodents are unable to penetrate into it. This fact has been confirmed by laboratory tests and our operational experience.
There are also additional protection methods, like in other types of houses. One of them is installation of metal mesh at the bottom of the wall.


6. Excellent sound insulation

The sound insulation of the straw wall, 40 cm thick, is equal to 56 dB, which is equivalent to a soundproofing of a brick wall of 2.5 m. Due to the dense structure of the walls, any external noise will not disturb You.

7. Earthquake resistance

Seismic stability of our panels is equal to 9 points on the Richter scale, just like in houses in Japan. Laboratory tests have proven this.


8. Worldwide popularity

In 2017 in France, more than 1500 frame buildings were built with the use of straw as an insulation material. In the US, more than 100,000 of similar houses have already been built. 

9. Autonomous energy

There is no need in gas connection in our Rainbow Ecosystem houses. Solar panels, heat collectors, recuperators, furnaces and solid fuel boilers are especially justified in warm energy efficient homes from our straw panels.


10. Universality, adaptability to any conditions

Rainbow Ecosystem lightweight prefabricated structures can be built on any ground (foundation), at any time of the year. The construction is fast and easy.

11. Construction time: 3-5 months

Development of drawings of a set of panels takes up to 15 days. An average production of a set of panels lasts 30 days, installation takes up to 10 days, internal and external turnkey finishing -  50 - 90 days, depending on complexity. The whole process takes up to 3-5 months.


12. Production by a certified manufacturer, quality assurance

We work according to the technologies patented in the EU. Our production is certified in Ukraine. Our product has all certificates of fire safety, strength, thermal conductivity and sanitary standards. Installation of panels is carried out by professional building brigades.
