Koston Noord BV

What Koston Noord BV does

Koston Noord BV is a regional Dutch insulation installation contractor headquartered in Zweins, Friesland, and operating as a wholly-owned subsidiary of Koston Nederland BV. The company was acquired by the Koston group in March 2013 and rebranded from Sijtsma Isolatie BV to its current name on 1 February 2014. It specializes in cavity wall, floor/crawl space, and roof insulation for both private residential customers and enterprise clients (primarily social housing corporations and regional construction companies) across the Friesland province.

The company's core technology platform is the Termokomfort insulation bead system, for which it holds certified system-processor status. The product portfolio centers on the HR-Termoparels® family — expanded polystyrene (EPS) beads with a latex binder originally developed by Shell/Termokomfort in 1976 — including the upgraded HR++ Termoparels® for narrow cavities, the biobased alternatives BioFoam Pearls® (Cradle to Cradle certified, 70% lower CO2 than standard EPS) and BioXbeads® (100% lactic acid, fully compostable), plus cellulose insulation sourced from EverUse. The proprietary Bodemhygrolatie® floor system combines an HR-Termoparels-filled polyethylene mattress with a vapor barrier for combined thermal and moisture control. Koston Noord holds KOMO, SKG-IKOB, ISSO, and Insula HSB certifications, and its products are registered for ISDE subsidy eligibility.

The business model is one-time installation services billed per project, with quotes provided on request. Distribution is direct field sales — phone, email, and website contact — supplemented by long-term contracts with regional housing corporations (Elkien, Wits Vastgoedonderhoud, Wonen Noordwest Friesland, Wonen Zuidwest Friesland) and partnerships with construction firms (Bouwgroep Dijkstra Draisma, Bouwbedrijf Lont, Jorritsma Bouw). PUR insulation and solar panel services are referred to partner companies rather than performed in-house. Marketing leverages the company website, a Facebook presence, a permanent unit at the Green Experience Centre in Leeuwarden, and trade-show participation (BouwBeurs 2015).
