Customized solutions, Doors, Enclosures, PVC Carpentry, Windows


As a synonym of future, energy savings and efficiency of the buildings through the enclosures of metal carpentry, in Disper we bet on the manufacturing of windows, balconies and PVC doors, we count with the support of a major manufacturer as CORTIZO, the Italian leader for PVC systems, innovating with special blends appropriately enriched with high level components.

We seek the desire to satisfy your project through carpentry which is respectful to the environment and taking care of timeless lines of design and aesthetics.

The Alphacan enclosures also offer us a barrier against acoustic pollution, and safety and protection for our home.

The PVC as a material, is already self-insulated, thus the multi-chambered profiles of carpentry keep us inside with the adequate conditions, independently of the external conditions without requiring high energy supply by the transmittance of cold and/ or heat generated by the outer enclosure and saving energy and greenhouse gas emissions to the atmosphere.


It is environmentally friendly and can be completely recycled. The energy consumption for the production of this material requires less energy than the majority of materials.


The action of time and atmospheric agents do not alter the PVC that only needs a water cleaning with neutral soap and periodical greasing of its fittings.


Extremely safe for any construction, the PVC is fireproof and self-extinguishing. This reduces the danger of new points of ignition induced by a fire.


The values of acoustic insulation are far superior to carpentry made with other materials, thanks to the property of the profiles that absorb the sound waves.
