Unión Carpintera

Company with more than 50 years of experience in the manufacture of doors, windows and enclosures with materials such as wood, aluminium, iron or PVC.

Our company is environmentally conscious. We work with manufacturers with a social conscience, which is why our products save a great deal of energy, achieving sustainable consumption.

PVC, thanks to its non-conductive properties, is a natural insulator with insulation levels superior to those of wood and, of course, to those of aluminium with or without thermal break. If you change your old windows to our PVC windows, you will save up to 70% energy in your home according to IDAE (Institute for Energy Diversification and Saving) data. In addition, we handle subsidies to change old windows and save on heating and electricity.
