Merx Windgo llp doors and windows are designed to withstand the harshest weather conditions and high-velocity storm winds and to block rainwater seepage. Made using powder-coated aluminium (lightweight with a high strength-to-density ratio) and uPVC, the products retain their shape, colour, and lustre for long even when exposed to temperature variations or intense UV radiations. With negligible thermal expansion/contraction and very low thermal conductivity, the materials deliver superior performance, excellent energy efficiency, and environmental sustainability. Merx is the only company providing ROTOI doors and windows that are designed and simulated for wind loads of different cities, building height and topography.
