Lightweight Precast Panels (ALC Panels) for Bird Nests and Swiftlet Houses
vPanel is an aerated autoclaved concrete panel (ALC Panel) – an ultra lightweight precast panel – made by Vodapruf Pte Ltd. vPanel uses a combination of fibre cement board and Lightherm Aggregates.
Ranging from only 35.8kg/m2 to 47kg/m2, vPanel has very high thermal and sound insulation due to the presence of Lightherm Aggregates, making it ideal for insulating bird nests and swiftlet houses – keeping them perfectly cool during peak day temperature – since high temperatures are detrimental to successful bird nests.
With the easy installation of vPanel(ALC Panel), it is both labor and cost saving. The finishing of vPanel is of high quality standard and does not require the need for skim coating. vPanel, commonly known as ALC Panel has also acquired certification such as non combustibility test, toxicity test, fire classification, fire rating and robustness test.
All tests are proudly supported by BCA’s Innovation Grant (iGrant).

Ways of Application
vPanel mainly has two application method for erection of wall as a non-load bearing wall structure. One as an internal wall and the other being external.
Internal Wall: vPanel is ideally used for internal partition wall due to its ultra lightweight properties, high thermal and sound insulation.
External Wall: vPanel can also be used as external wall panel for modular houses, low-cost building, factories, hotel, apartment and villas etc.
Preparation (Based on one of the installation method, refer to our video)
This preparation video is based on one of vPanel’s (L-Bracket and Rebar) method for installation.
Other than the three key features of vPanel which are ultra lightweight properties, high thermal insulation and high acoustic insulation, It has other as important characteristics as well. They are high compressive strength, moisture-proof, fire-resistant and heat insulation (thermal efficiency).

The key unique selling point (USP):
- Well-opened groove TOP and bottom
- Cut-To-Size (No wastage)
- Waterproof treatment to prevent cracks between joints and seepage
- Manufactured in Malaysia, thus shorter lead time
- Ultra lightweight, thus high productivity, less intensive labour
- Different thickness 50mm-200mm
- Lightest panel in the industry with a density of only 750kg/m3
vPanel has a wide range of thickness that caters to different specification and technical requirements, from 75mm thick to 200mm thick. The most commonly lightweight precast wall panel used are 75mm thick and 100mm thick. Below is a comparison table between the two most common thickness used in the construction industry. Vodapruf is working towards a new development in 25mm thick, 50mm thick and 250mm thick in the near future with test reports in the midst of developing and finalizing.
|Technical Specification||vPanel 75mm thick||vPanel 100mm thick (Common Demand)|
|Per m2 weight (kg)||35.8kg||47kg|
|Panel width (mm)||600mm||600mm|
|Standard Panel Length (mm)||2400mm||2400mm
|Sound Transmission STC, ISO 140-3:1995||STC 35||STC 38|
|Thermal Conductivity (W/mK)||0.125 W/mK||0.125 W/mK|
|Water Penetration (BS 5234 Part 2)||No evidence of water penetration||No evidence of water penetration|
|Strength & Robustness (BS 5234 Part 2)||Pass||Pass|
|Fire rating (BS 476, Part 22:1987)||3 Hours||4 Hours|
