HPL requires Very low maintenance is required for the building facade as the cladding forms a protective layer throughout the building. This makes the building more durable than a traditional building finished with wall paint.
The HPL coating protects the building from pollution, dirt can make the building look very shabby when an only paint is used as a finishing surface.
Coating materials such as metal, stone, would give a very good aesthetic and texture to the building.
HPL makes the building weatherproof because it is very resistant to outdoor weather conditions such as wind, sunlight, and rain. It also acts as a protective layer and prevents water infiltration into the interiors.
It creates a very good layer of thermal insulation that protects the interiors from the absorption of extreme heat.
HPL coating acts as a soundproofing layer that prevents outside noises from entering.
This is an expensive proposition because it includes significant material and labor costs, but it makes the building more sustainable in the long run.
