More than 12,500 UK window and door companies buy in sealed units, Insight Data reveals

New analysis from Insight Data has identified more than 12,500¹ window and door companies across the UK that buy in insulating glass units (IGUs) rather than manufacturing their own.

The findings highlight the scale of the addressable market for sealed unit manufacturers at a time when supply relationships across the sector are coming under renewed scrutiny.

Insight Data’s specialist Fenestration database distinguishes between companies that manufacture sealed units in-house and those that source them externally, giving suppliers a detailed picture of the market and where potential opportunities exist.

The data goes further than simply identifying businesses. Insight Data also records estimated production and purchasing volumes, company size, product activity, key decision-makers and other commercial intelligence, allowing manufacturers to identify and prioritise the prospects most relevant to them.

Andrew Scott, founder and CEO of Insight Data, said: “The IGU sector has consolidated significantly in recent years with the rise of automation and economies of scale, but there are still thousands of window and door companies buying-in sealed units. Knowing who they are, what they buy and the likely volumes involved is what turns market potential into a genuine sales opportunity.

“Markets change quickly. When they do, suppliers need accurate intelligence that allows them to respond immediately rather than relying on historic customer lists or waiting for enquiries to arrive.”

The information is available through Insight Data’s Salestracker platform, enabling users to segment the market, identify relevant contacts and target prospective customers through sales and marketing activity.

Insight Data continuously researches and updates businesses throughout the UK fenestration sector, providing suppliers with a live view of the companies operating within their target markets. To discover more, visit: https://www.insightdata.co.uk/
