uPVC or aluminium? Start with the brief.

The first question is not which material wins in every situation. It is what this particular opening needs to do, how it should look and how it will be operated and maintained.

Compare the proposed profile system, glass, reinforcement where applicable, hardware, drainage, finish and installation arrangement. Thermal, acoustic and weather-performance claims should relate to an identified, applicable configuration—not merely the material name.

Some projects call for aluminium in one part of the building and uPVC in another. A coordinated opening schedule helps keep those decisions deliberate. Magnesta works with aluminium system families and VEKA uPVC systems, allowing both routes to be discussed in context.
