UNDERSTANDING R-VALUE
What is R-Value?
R-value measures how well insulation resists heat flow. The higher the R-value, the better the insulation’s ability to keep heat out in summer and retain warmth in winter.
Why R-Value Matters
Choosing the correct R-value helps to:
Improve energy efficiency
Reduce electricity bills
Increase indoor comfort
Reduce strain on heating and cooling systems
In South Africa, minimum R-value requirements vary depending on climate zones and building regulations. Installing insulation that meets or exceeds these requirements ensures compliance and optimal performance.
CORRECT INSTALLATION IS KEY
Even the best insulation will underperform if installed incorrectly. That’s why our team follows manufacturer guidelines and SANS building standards to ensure your insulation delivers the results it’s designed for.
