CSR Bradford Fireseal

The Bradford Fireseal range is made from non-combustible Rockwool, an insulation material specially formulated to provide fire protection. It is manufactured by spinning a molten mixture of natural rock and recycled blast furnace waste products into fibres which are bonded with a thermosetting resin.

The Bradford Fireseal range includes products that meet fire regulations for specific applications, such as:

  • Party walls
  • Curtain walls
  • BAL – 12.5 to BAL – 40 and BAL – FZ rated

Insulation blankets

Kingspan AIR-CELL

Kingspan AIR-CELL is a versatile range of fibre-free flexible reflective insulation for roofs, walls and floors. The reflective foil reflects up to 97% of radiant heat away from its surface. The small amount of heat absorbed is then further reduced by the conductional resistance of the polymer air cell structure, keeping you cool in summer and warm in winter. Kingspan AIR-CELL‘s resistance to all forms of heat flow translates into energy cost savings of up to 50% for the building occupier and reduced greenhouse gas emissions for the environment.

Bradford Anticon

Bradford Anticon combines two very effective forms of insulation into a single product to provide these benefits.

The reflective foil acts as a barrier, which reduces the radiant heat entering the roof space by up to 97% and also controls condensation, while the insulation blanket absorbs outside noise and dramatically slows the transfer of heat into and out of a home.

CSR Polyair Insulation

Bradford Polyair™ is a range of thermo reflective insulation products that reduce radiant heat gain in roofs and walls. The products can be used in a range of residential and shed applications.

Multitel BAL 12.5-40 Blanket

Bradford Multitel™ BAL 12.5-40 is used to seal off areas from potential ember ingress in bushfire prone areas.

Bradford Multitel™ is manufactured from an engineered glasswool insulation blanket. The blanket is manufactured by spinning molten glass, containing up to 80% recycled content, into fine wool like fibres.

These are bonded together using a thermosetting resin. The product can be identified by its golden appearance.

Roof sarking

Acting as a protective second skin under your roof, roof sarking provides benefits such as:

  • Protecting against mould and ceiling damage caused by roof leaks
  • Limiting the amount of dust that can enter a home

Roof sarking is available in a range of insulation types with additional capabilities such as improving a homes thermal performance or providing a secondary form of ember protection for BAL regions ranging from 12.5 to 40.

Roof sarking regulations

According to the Building Code of Australia (BCA), it is mandatory to sark all tiled, residential roofs with a rafter length over 6 metres. This regulation applies regardless of roof pitch. The BCA has other requirements relating to how a building is protected from external moisture, so it is considered best practice in the building industry to sark all tiled and metal roofs during the initial build.

Ask Dahlsens about our competitive pricing for roof sarking installation services. Roof sarking is installed under tiles and helps to minimise water damage caused from weather events such as wind-driven rain.
