AHPL Vs HPL: Making Informed Choices for Interior and Exterior Surfaces


Contemporary and traditional home designs have gone backdated and people are welcoming more sleeker, modern, and aesthetic ideas. Therefore, to achieve unique looks and styles, the two cladding materials that are in high demand in the architectural world are HPL and AHPL sheets.

However, at first glance, these two sheets have a similar visual appearance but have multiple differences as well. To understand the differences in AHPL vs HPL, continue reading…

AHPL Sheets

AHPL what is it? Aluminium High-Pressure Laminates, are HPL sheets but instead of paper, they use aluminium which makes them more sturdy and sustainable.

In texture and colour, AHPL sheets imbibe the beauty of nature. If you want to have the look and feel of stone, wood, and marble altogether, choose the AHPL sheets.

Now, let’s discuss the composition part. These high-pressure laminates are the cladding materials made of aluminium and thermoplastic core. This process makes it of the best quality while comparing it to paper HPL boards. Moreover, these sheets are easier to bend, nearly to 90 degrees.

HPL Sheets

HPL sheets are the acronym for High-Pressure Laminate. When HPL sheets are manufactured with the right amount of pressure and heat, they become extremely strong. In contrast to PVC laminates, HPL sheets do not cut corners on quality and provide long-term assurance. It makes up 70% of the paper in the core, with thermosetting resin covering up the remaining area to boost the HPL sheets’ strength. Thus, HPL sheets are a preferable option than PVC laminates.


Dissimilarity in Coating

The UV coating on the HPL board or HPL sheet provides it with a glossy appearance and stain-resistant qualities. It means applying an appearance or design to the surface of paper that has been printed and freezes when placed under UV radiation. However, metallic coatings and 3-D illusion finishes are not affected by this.

FEVE/PVDF coating, also known as powder coating, is applied to AHPL to improve characteristics like corrosion and weather resistance. A building’s external appearance can be improved with the use of AHPL, which is available in a variety of hues and textures.

Standard of the Sheets

The HPL board, or regular HPL, is not immune to bacterial or fungal infections. Neither are they resistant to strong pressure, impact, scratches, or abrasions. Hence, the absence of all these traits makes it vulnerable and can cause harm to the structures. As a result, it eventually loses its high-quality appearance.

AHPL sheets from reputed manufacturers do not react to moisture and do not stain, yet they are resistant to heavy pressure or impact. When compared to paper-based HPL sheets, Viva’s AHPL offers minimal moisture absorption and termite and bacteria-proof sheets, making it a more durable product.


The HPL (High-Pressure Laminate) sheets require more care because they are prone to damage. Cleaning stains and contaminants from the HPL board’s surface is a difficult option, Due to its UV coating. In addition, it is more challenging to replace a single HPL board sheet than it is for AHPL (Aluminium High-Pressure Laminate) sheets.

On the other hand, AHPL sheets are stain and filth-resistant, making long-term maintenance easier. You can use wet wipes to clean the surface area quickly and easily. Furthermore, as an AHPL sheet is secured using rivets and nuts, changing it in case of damage is an easy process. This is very different from the tedious replacement process that comes with HPL sheets.

Difference in Installation Procedure

One of the critical processes in facading is the installation. When we talk about AHPL vs HPL in the installation process, we need to understand the material features.

As HPL is heavier, it is challenging to install them. You may want to avoid them for the fact that they cannot bend at a 90-degree angle. For this drawback, HPL sheets are less appropriate for use in rooms or sidings where material flexibility is required.

However, AHPL sheets provide a more flexible option. They are made with an aluminium base, which makes them flexible to bend at a ninety-degree angle whenever needed. Besides they are lightweight, making the installation process easier. It enables AHPL sheets to be easily fastened onto wall siding or in areas where an L-shaped design is necessary. Hence, for their broad range of applications, AHPL is a recommended option from an expert end. If you are looking for items to accomplish projects requiring both resilience and adaptability, choose AHPL sheets.

For example, AHPL sheets are highly suitable for a range of construction and design requirements when used effectively in architectural projects with complex angles or curved surfaces.

Bottom Line

When compared to an HPL sheet, AHPL is a better material because of its greater resistance to cracking, superior designs, and ability to bend 90 degrees. You must choose the leading producer’s AHPL sheets that beholds strong physical characteristics, offering reasonably priced items, and acoustic sheets for your house.
