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.

What R rating should ceiling installation be?
There are a range of insulation R rating requirements depending on the climate zone the project is being built in.
This table shows recommended R-values for roofs, walls, and floors based on climate zones, colour of the roof (indicating absorptance), and direction of heat flow. The values vary depending on these factors to help optimise insulation for different environmental conditions.
Insulation FAQs
How many different insulation types are there?
There are 2 main types of insulation products:
- bulk: which primarily affects conduction heat flow between objects that are touching
- reflective foil: which primarily affects radiation heat flow.
What is the best type of insulation?
The most effective type of insulation is bulk insulation. It works by capturing millions of tiny pockets of still air within its structure. These air pockets create resistance to heat flow, giving the material its insulating power. It’s essential not to compress bulk insulation, as this reduces the air pockets and diminishes its ability to insulate. Bulk insulation comes in forms such as batts, blankets, and boards, or as loose fill.
Insulation benefits
Insulation offers numerous benefits, enhancing comfort, energy efficiency, and sustainability in homes and buildings. Here are some key advantages:
- Improved Energy Efficiency
- Enhanced Comfort
- Noise ReductionEnvironmental Impact: Reduced energy usage lowers greenhouse gas emissions, making insulation a sustainable choice that contributes to environmental conservation.
- Condensation Control
- Increased Property Value
- Fire Protection
- Extended Lifespan of HVAC Systems
