Broad incumbents

• Knauf Insulation: Global manufacturer of mineral wool and blown-in insulation products under the Supafil and Timberframe brands that Plus Isolatie installs. Indirectly comparable as the upstream supplier and broader category incumbent.
• Kingspan Group: Global building envelope manufacturer with substantial residential and commercial insulation product lines. Not a direct installer competitor, but a broad incumbent whose products and pricing shape the Dutch insulation market.
• Saint-Gobain (Isover): Major global insulation manufacturer whose Isover brand supplies glass wool and other materials commonly used in Dutch residential retrofit work. Comparable at the category level rather than as a direct service peer.

Direct peers

• ENOVA Isolatie: Specialized Dutch installer focused on spouwmuur-, vloer-, dak- and kruipruimte-isolatie for residential customers. Comparable service portfolio, customer base, and ISDE subsidy-assisted sales motion.
• De Isolatieshop: Netherlands-based residential insulation installer offering spouwmuur- and vloerisolatie with similar pricing tiers and Dutch homeowner targeting. Comparable scale and customer segment.
• IsoPlus Isolatie: Dutch residential insulation installer offering cavity wall, floor, and roof insulation with similar ISDE subsidy support and field sales model. Closely comparable in size and customer focus.
• Isolatie.com: One of the largest Dutch residential insulation installers, offering spouwmuur-, vloer-, dak- and kruipruimte-isolatie for homeowners. Operates the same sales-led, free-quote GTM and targets the same 1910-1991 Dutch housing stock as Plus Isolatie.
• Homij (VolkerWessels): Dutch technical services and installation subsidiary of VolkerWessels performing residential insulation and HVAC work. Larger and broader than Plus Isolatie but operates in the same residential installer space with comparable certifications.
• Comfortabel Wonen: Dutch residential insulation company offering cavity wall, floor, roof, and attic insulation with on-site advisory visits and subsidy support. Direct overlap with Plus Isolatie's product and service model.

Others
