This company currently has ("February 2020") an "offer" in which they claim to offer 25% cheaper because it happens collectively. Don't fall for it!

I have compared their offer with other companies and now I get better insulation for a 25% * lower * price than the offer from Nederland Isoleert.

The consultant who visited me was otherwise friendly and had enough knowledge, but he must also be aware that it is not a real offer.
