Good insulation can significantly save energy and of course costs heating / cooling.
Insulation is effective only when the insulation is at least 8 cm. In most cases I encountered in Israel, the insulation layer height ranges from 2-4 cm only. Also, Israel is not common with using steam blocker which prevents the entry and exit of air in and out. without blocking steam, even good insulation will be effective only at the rates of 20% to 30%.


Steam blocking prevents diffusion of steam and or water by being built attic space between the tiles and the roof membrane and interior roof. prevention is important because wet insulation layer does not create another effect of the insulation.


Insulation to perform effectively in terms insulation and vapor blocks in the right places based on the physics of building, Required academic knowledge and experience. Towards the end of the work we perform quality control isolation using the “BLOWER DOOR TEST” test of the density of the air in the roof.


Existing roof insulation, mineral Vella term between roof rafters.
Steam blocks lying underneath which was sealed without any air flowing can enter and exit for maximum insulation. This method is that manufactures complete isolation that results in significant energy savings.

Additional insulation methods

An example of a good assumption blocking Steam
In order to block Steam will work. Well, it should be fixed to the wall with Unique Glue.

An example of a professional connection for steam block for a window.

Most modern insulation system Europe. Insulation is installed over Roof rafters, creating a closed system Allows residential roof without the need Winter heating and / or air in summer

150 mm rigid insulation for roof Flat sheets installed over Bituminous. Installing insulation in this creates a savings of about 40% – 50% in energy consumption

Hemp insulation


This product is a licensed European high technical quality.
Hemp comes in plates and sheets Galilee.
It is used as insulator for walls, roof and floor.
The material is free of components that causes skin irritation and dust-free body
– without concerns to your body this product is 100% healthy.

Hemp has a higher insulating value for heat and cold. Hemp insulation ensures protection against penetration of cold in the winter and protects against heat penetration in summer.Best diffusion is due to the natural material and automatically produces circulation of moisture in the air and the room climate stayes healthy. Isolation Hemp is impossible for mold formation. Attached all the quality certificates and licensing of the product in Germany and Europe.

Additional insulation methods

Free of mold

Safest material for the home owner is hemp insulation.
European Institute for Healthy Living conducted a study which found that in every three building / house exists mold in the house.
When you  put hemp insulation and good ventilation, no mold formation would be in the house.

There is no cost during the evacuation of the product.
Hemp is a natural product and if you decide at some point to replace a new isolation / other, you can throw  him without cost along with the regular trash.
Unlike other insulation materials – glass wool, rock wool, polystyreneconcrete etc. – that a replacement there are many costs evacuation material.

Buildings from the 60’s to the – 80 with a wall thickness of 360 mm are energy balance U-Wert von 2,08 W / (m2lK). As a result, the energy required for heating to get a 22 ° C in room is 16.5 square meter diesel exterior wall. The formula for finding the energy required for heating is (U-Wert * 8 = l Öl je m2 A / a) When using Hemp insulation thickness 150 mm is the “U-Wert” better. It changes to – (0,23 W / (m2lK). Energy savings resulting from the use of hemp isolation wall is by about 90%

energy efficiency table

This is a document of the largest independent organization in Germany. According to the certificate – Checking the 19 insulating materials – Hemp insulation is with a grade of 1.9 – the highest.

This document is from the European Union optimal recycling of natural resources by Hemp.

Hemp insulation recievd in June 2002 a diploma from the European Union for being a natural product isolation at the highest level.
