Back in 2006 Scheltema was the roofing contractor for the new head office for Pick n Pay in Kenilworth. Now 18 years later Scheltema again is the contractor appointment to replace the tiled roof with a concealed fix metal roof sheeting system.
The roofing project for the Pick n Pay head office in Kenilworth marks a significant upgrade from the original tiled roof to a concealed fix metal roof sheeting system. This transition highlights a growing emphasis on energy efficiency and sustainability in commercial buildings, particularly as electricity costs in South Africa are projected to rise sharply in 2025.
The concealed fix roof design is not only modern but also highly compatible with solar installations. Utilizing a non-penetrating mounting bracket is crucial to preserve the integrity of this roof system, preventing leaks and damage that could arise from invasive installation methods.
The installation of properly sized purlins was necessary since the existing battens from the tiled roof could not support the new sheets. These purlins create a strong framework for the concealed fix system, ensuring durability and stability. Additionally, the incorporation of 75mm blanket insulation with an R-value of 1.92 K/W significantly enhances the building’s thermal efficiency. The high R-value indicates effective heat retention, leading to substantial reductions in energy consumption, which is especially beneficial during extreme weather conditions.
With the rising electricity rates, investing in energy-efficient insulation and solar energy is becoming increasingly vital for businesses. A relatively small solar installation, such as a 5 KW system, can yield significant financial savings—up to R 23,000 annually. When considering the expansive roof area of 7000m² available at the Pick n Pay head office, the potential for solar energy generation and subsequent cost savings grows substantially.
Adopting these modern roofing and insulation solutions not only offers immediate financial benefits through energy savings but also represents a commitment to sustainability and reduced environmental impact, encouraging other businesses to follow suit in enhancing their energy efficiency strategies.
