How We Built the UK’s Top Fenestration Supplier Database

When the construction industry relies on precise, up-to-date information, your data supplier can’t afford to cut corners. At Insight Data Ltd, we’ve built the only genuinely dedicated Fenestration Database for the UK fenestration sector—providing the most comprehensive information for companies targeting fabricators, installers, and glazing firms.

Whether you’re in sales, marketing, or commercial operations, having direct access to accurate prospect data is no longer a luxury. It’s a necessity.

A Database Designed for the UK Glazing Market

The Insight Data fenestration supplier database contains over 13,000 active contacts, including:

Window and door fabricators (uPVC, aluminium, timber)
Installers and home improvement companies
Glass processors and IGU manufacturers
Trade counters and glazing suppliers
System companies and commercial fenestration contractors

Each record includes key contact information, product ranges, regions served, business type, and credit rating.

Integrated with real-time business intelligence sources
