Particle board flooring

Also referred to as chipboard or low density fibreboard (LDF), particle board flooring is frequently used for interior flooring in residential builds. Structural grade particle board sheet flooring is suited for installation in platform construction projects where the floor is laid prior to the walls. As it’s made from waste products such as wood chips, shavings and sawdust, particle board is an affordable and accessible option.

Dahlsens supplies STRUCTAFlor green, red and yellow tongue particle board products.

This durable alternative to particle board flooring is moisture resistant and resilient. HardiePanel has also been found to be non-combustible in accordance with the provisions of the Building Code of Australia, so can be used for flooring in bushfire prone areas.

Autoclaved Aerated Concrete (AAC)

An extremely versatile product, AAC (Autoclaved Aerated Concrete) is a popular structural flooring product made from concrete and aluminium powder. During production, the aluminium powder causes the concrete to rise (similar to bread dough) and the resulting concrete product is about 80% air, making it strong yet lightweight. AAC is available in both slab and block form.

Not limited to structural flooring applications, AAC can also be used for internal or boundary walls, external cladding and even fencing for residential and commercial buildings. If your clients are seeking a sleek look without the hefty price tag, AAC is an attractive option. Customers who value sustainability will love that AAC is recyclable, and budget conscious clients could enjoy lower heating and cooling costs thanks to AAC’s high thermal mass.

Other benefits of AAC products include:

  • Easy installation
  • Excellent soundproofing qualities
  • Termite resistant
  • Fire resistant
  • Easy to cut for plumbing and electrical access

Hebel PowerFloor

Hebel PowerFloor is made from prefabricated AAC panels reinforced with 75mm steel, which significantly improves the strength and durability of the product. PowerFloor can be easily installed over steel or timber joists, providing an ideal base for floor coverings such as carpets and tiles.

PowerFloor has no bounce or flex that is often present in particle board flooring, and is an ideal option for first floors, suspended ground floors, decks and balconies. Help your clients keep their home warmer in winter and cooler in summer by using PowerFloor products for your next project.

Power floor is available in size 1800x600x75.

All Hebel products and systems are compliant with AS 5146 (Parts 1-3)
