Selman from ISOSEL carried out two forms of insulation in my house: (1) floor insulation (vloerisolatie) and (2) cavity wall (spouwmuurisolatie) insulation. He - and his team - were extremely efficient, reliable and friendly. I am very pleased with the way Selman communicates and with the work that he and his team carried out.

Isosel installed the TONZON floor insulation. The company was fantastic. Quick to come to my home and make an offer. They performed and fully completed the work on the day that was planned to a very high level. The people are very friendly and you can see that they really take pride in what they do. The TONZON insulation seems to be working very well as the ground floor heats up very quickly now.

After the installation in our house earlier this year, of the TONZON floor insulation system, we are now enjoying during the colder days, a warmer marble floor for longer periods of time, with lower usage of gas and a turned-down thermostat for a more comfortable and relaxed living environment. The entire process was flawless - from the initial chat and system demonstration at our home to final material delivery, neat installation and provision of the necessary system documentation. The stunningly high inflation and exorbitant higher energy and consumer goods' prices at the moment are hurting everyone, no doubt. Turning off the gas used for floor heating during winter is no-one's desirable option, but lowering it is better and possible. Additionally, the higher gas prices mean that the return on investment period eventually becomes less. With all the advantages and finally, the almost-one-third government subsidy off the purchase price, made our decision to have the floor insulation system installed in our home, a 'non-brainer'. In view of everything stated, I strongly recommend that you seriously consider having a floor insulation system installed in your house and reap the benefits like many others have done before you. In doing so, you will also become, like many others before you, a small, active and essential contributor to saving our precious planet through using less gas, lowering dangerous emissions and improving the quality of our environment. The continuing climate change issues are affecting us ALL. Therefore, let us not aim for a DESTRUCTIVE but a CONSTRUCTIVE goal.

I got the crawl space insulated from this company. They did a very nice job. The response was timely. They provided complete details for all the work that was done. The post installation service is also great.
