Traditionally wooden materials have been used extensively as a construction material, both for exterior beauty and interior decor. However, in spite of its many advantages, usage of wooden materials have some serious shortcomings. Firstly, being a natural material, cutting of trees for wood impacts our environment and lead to climate change also. Hence usage of wood is not eco friendly. Secondly, being a natural material, it has a very limited life and requires extensive maintenance.
Recognizing these challenges, the Citybond has introduced Citybond HPL, a High Pressure Laminated (HPL) Aluminium Composite Panel. Citybond HPL is more durable and elegant in looks as compared to wooden materials and is also highly weather resistant. It can be easily used for any exterior cladding application or for interior decoration purpose.
Citybond HPL helps mitigate the shortcomings of wood as it is manufactured using Aluminium coil with a double-layered PVDF / Lumion Coating that is resistant to dust. It also has a Polyethylene Core that makes it resistant to water, fungus and termite.
Citybond HPL is manufactured at our plant state-of-the-art facility using stringent quality processes, resulting in a high quality premium panel, which is highly robust and effective under extreme weather conditions, much more than other brands of High Pressure Laminates or any wooden material.
And adding to this, Citybond HPL comes in a wide variety of colours, textures and sizes to meet every need and shade. Citybond HPL also offers the facility to provide you with customized colours and sizes, as per your individual bulk requirements. Our wide distribution network and efcient team ensures that you get the prompt service that you need. Citybond HPL is brought to you at a very competitive price to meet your needs. Coupled with its unmatched quality, Citybond HPL has today redened the concept of high-end façade, exteriors and also interiors. Whether it is a villa, housing society, corporate ofce or a resort, Citybond HPL is your perfect choice, instead of wood.
With Citybond HPL, you can now get premium wood like interiors or exteriors. Choose from a wide range of natural shades and textures to give your design that extra edge. Citybond HPL is super flexible and can bend, fold and turn easily. Straight and angular routing assists in bending the panels to cover angles, clad columns, create linear ‘caps’ or trays.
