Solutions for construction since 1836
Heinrich Meyer-Werke Breloh GmbH & Co. KG is a family business founded in 1836 in the Lüneburg Heath, today run by Volker and Moritz Meyer in the 6th and 7th generation. The portfolio includes custom-made windows made of PVC, PVC-aluminium, wood and wood-aluminium, entrance doors, lift-and-slide doors, sun shading systems, the series-production wall element HM Modul®, carports including PV carports, patio covers (Sunports), garden sheds (Gardenports) as well as calcium silicate brick. Everything is manufactured exclusively in Germany: windows and doors at the modern plant in Bispingen, wood products at the plant in Munster/Breloh. The entire value chain – from the company's own forestry and gravel and sand extraction to the in-house haulage company with just-in-time delivery and installation – is provided from a single source. Customers include property developers, construction companies, prefabricated house manufacturers, dealers, real estate companies and end customers. Innovations such as the HM Modul® have received the TOP 100 seal several times.

As aluminium cladding on windows, for external venetian blinds, powder-coated elements and sun shading.
Steel
For wood-steel versions of the patio covers, powder-coated in RAL colours.
Glass (laminated safety glass, multiwall polycarbonate sheets)
Laminated safety glass and multiwall polycarbonate sheets for glazing with high weather and UV resistance.
Calcium silicate brick
Produced in the HANSASTEINE group for solid construction.
Gravel & Sand
Own gravel pits as a raw material source in northern Germany.
