Glasshouse Re-Roofing & Re-Purposing Services
Upgrading your glasshouse roof with polycarbonate, composite panels or sandwich systems offers a wide range of long-term benefits that can dramatically improve performance, safety and usability. These modern roofing solutions provide excellent impact resistance and are far more resilient to harsh weather conditions than traditional glass. Composite and sandwich panels, in particular, deliver superior thermal insulation, helping to maintain stable internal temperatures, reduce heat loss and lower ongoing energy costs.
At Commercial Glasshouse Contracts Ltd, we specialise in professional glasshouse re-roofing solutions using high-performance polycarbonate and composite panel systems, alongside Dutch-manufactured sandwich panel systems supplied through our trusted partners in the Netherlands. Whether you are experiencing frequent glazing repairs, inefficient climate control or ageing roof materials, a modern roof upgrade can provide a durable, cost-effective solution that supports healthier crops, safer working conditions and improved energy efficiency.
Re-Purposing Existing Glasshouses
Re-roofing can also open the door to re-purposing your existing structure. We have successfully worked on projects where glasshouses have been transformed into cafés, retail spaces and other public-access buildings. By improving insulation, light control and weather resistance, an existing glasshouse can be adapted to suit an entirely new function while retaining its structural value.
