Knauf Prices For South African Homes
The price of Knauf insulation per square meter can vary depending on the specific product, thickness, and application.
On average, the price of Knauf insulation ranges from R100m² to R120m². Thicker insulation products or those requiring more complex installations will typically cost more. For instance, higher R-value products, which provide better thermal and acoustic performance, may have a premium price.
When calculating the cost of Knauf insulation for your project, it’s important to consider both the thickness of the material and the area you need to cover. Additionally, the installation complexity can also impact the final price.
For example, insulating a flat roof or an area requiring additional work, such as removing ceilings or lifting the roof for installation, will generally incur a higher cost per square meter compared to a standard pitched roof with easy access to the installation area.

How to Install Knauf Insulation
Installing Knauf insulation is a straightforward process, but it’s essential to follow the correct steps to ensure maximum performance and energy efficiency. Whether you’re insulating a roof, walls, or floors, here’s a general guide to help you with the installation of Knauf insulation.
1. Prepare the Area
- Safety First: Before starting, make sure to wear the appropriate personal protective equipment (PPE), including gloves, goggles, and a dust mask.
- Clear the Area: Ensure the area where you’ll be installing the insulation is clean and free from obstructions. If you’re working in a roof space, check for any exposed wires, plumbing, or other obstacles.
2. Measure and Cut the Insulation
- Measure the Space: Start by measuring the dimensions of the area you plan to insulate (e.g., roof cavities, walls, or floors). Knowing the size of the space will help you determine how much insulation you need.
- Cut to Fit: Knauf insulation comes in pre-cut rolls or batts, but if you need to cut the material to fit a specific space, use a sharp utility knife. Measure and mark the desired length and width, then carefully cut the insulation to size.
3. Install the Insulation
- Roof Insulation: If you are installing Knauf insulation in a roof cavity, begin by placing the insulation between the rafters. Ensure that the material fits snugly between the beams without being compressed, as compression can reduce its thermal performance.
- Wall Insulation: For walls, simply slide the insulation between the studs, ensuring it fits snugly and covers the entire space. If necessary, staple or secure the insulation in place to prevent it from shifting.
- Floor Insulation: For floors, lay the insulation in a similar manner between the floor joists. Ensure that the insulation is evenly distributed across the space and fits tightly without gaps.
4. Ensure Proper Coverage
- Make sure the entire area is covered with insulation, and ensure there are no gaps or spaces where heat could escape. If you’re working in an area with difficult corners or angles, trim the insulation as needed to fit.
By following these steps, you can successfully install Knauf insulation to enhance your home’s thermal and acoustic performance, improve energy efficiency, and create a more comfortable environment. If you’re unsure about the installation process, it’s always a good idea to consult a professional installer to ensure the best results.
