About

A heritage of innovation and care, at the heart of Britain.

Hambleside Danelaw’s building products story began in 1975, when an investment opportunity presented itself in the form of a patent for an innovative glass reinforced polyester (GRP) roofing product.

A year later, Hambleside Manufacturing Limited was established; to formally produce and market the GRP products.

After diversifying into rooflights and cladding, in 1983 we began manufacturing valley gutters for a Daventry-based new client, Danelaw Laminates Limited. Having worked closely for several years, discussions on a merger took place between the two companies, and a deal was done in 1992. Subsequently, Hambleside Danelaw was born.

Today, we manufacture a range of pioneering and innovative GRP products on our sophisticated continuous profiling production lines. Products conceived in Britain, made in Britain.

The products are manufactured using a range of raw materials, including glass rovings and mats, varying fire resistant and retardant resins and pigments. In addition, our factory operates vacuum-forming and injection moulding machinery capable of producing products with shot weights up to 1400 grams, of which most products form part of our Pitched Roofing range.

Throughout our history we have led the way in the industry, accommodating legislative and regulatory changes within our product designs and keeping abreast of BS EN ISO standards. We have developed innovative solutions and patented designs, all with the purpose of making our customers’ working life as easy as possible.

All of our products are manufactured to BS EN ISO 9001 Quality and ISO 14001 Environmental standards whilst operating to ISO 45001 Occupational Health and Safety standard.

We have the capability to manufacture bespoke products and welcome all enquiries.
