Nordian Capital acquires growth company De Isolatieshop

Zevenaar, May 12th 2021 – De Isolatieshop, a young and fast-growing specialist in insulation materials for consumers and businesses, will become part of the Nordian Capital portfolio. With this acquisition, De Isolatieshop and Nordian Capital aim to expand the success in the Dutch market to the Belgian and German markets.

Since its founding in 2010, De Isolatieshop has shown impressive exponential growth in the Dutch consumer market. The success of De Isolatieshop is driven by the combination of its broad and deep assortment, the large inventory, next day delivery and customization possibilities which is unique in the Netherlands. To accelerate its growth and to expand to the Belgian and German markets, De Isolatieshop has opted for a sale to Nordian Capital.

Room to challenge new markets
Tim van Haaren and Martijn Aaldering, founders of De Isolatieshop: “Our company has experienced incredible growth, which is not about to stop anytime soon. This is confirmed by the significant developments in the insulation market. We want to give the company all the space it needs for this further growth. Nordian is equally minded and has a shared ambition. They have the track record of guiding companies that combine e-commerce and logistical services to the next phase, assisting them in internationalization and that is where the great opportunities lie. Firstly, the Belgian market - which has many similarities with the Dutch market and secondly, the mature German market which is known for its sustainability and has more subsidies. In both countries we are an innovative challenger for both consumers and businesses.”

Joost Sars, managing partner at Nordian: “This is a true Nordian transaction. A young company, rapid growth, internationalization, e-commerce and an operation on-the-ground. With these characteristics, De Isolatieshop has become the largest online supplier of insulation materials in the Netherlands. The company is now entering a new phase, focusing its growth and further professionalization of the business. From the start there was a click with the two founders, who are driven, fast, decisive and down-to-earth. They also mentioned the need to find new general management as their successors for this next growth phase. Tim and Martijn will eventually step down and remain involved with De Isolatieshop as strategic advisors. As true entrepreneurs, they reinvest in the company as shareholders. Their commitment remains unchanged.”
