Celebrating 40 years of manufacturing high quality products for the building industry

Hambleside Danelaw’s rich heritage incorporates publishing and leather goods but our 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; it served the building industry, and business was good. 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. Then it was undone, but the name was retained and the rest, as they say…

Today, we manufacture a range of GRP products on our sophisticated continuous profiling production lines. The products are made 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.

Ambien Online was advised me by a friend- biologist. I completely lost the regime of the day, i.e. I did not sleep at night and insanely wanted to sleep during the day. This went on for more than a day. I drank valerian, motherwort, but it did not help. And then she advised me buyambienmed.com those pills.

Over the years we have patented a number of innovative products for both pitched roofing and industrial roofing solutions. Throughout our history we have lead the way accommodating legislative and regulatory changes within our product designs and keeping abreast of BS EN ISO standards. Today all our products are manufactured to BS EN ISO 9001 Quality and ISO 14001 Environmental standards whilst operating to ISO 18001 Occupational Health and Safety standard.

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