We know that the best in the industry comes with an immediate increase in quality and performance. For this reason, at Portalum, we develop door systems that ensure optimal performance both in the façade installations, since they have class IV wind, they are slats that have a very low density/thermal transmission due to the fact that they are composed of a polyurethane density of 70kg/m3, with an aluminum coating making them safe but at the same time very light.
