Why Climate Matters
South Africa’s regions vary widely. The right aluminium window style, glass and sealing can improve comfort, durability and energy use. Below we match common climates to practical choices.
Hot & Sunny (e.g., Gauteng summer)
- Top-hung or sliding windows for controlled airflow.
- Low-E or tinted double glazing to reduce heat gain and glare.
- Quality rubber gaskets + brush seals to limit dust ingress.
Windy / Exposed (Highveld & coastal headlands)
- Side-hung casements with strong friction stays and multipoint locks.
- Laminated safety glass for stiffness and security.
- Reinforced frames; ensure AAAMSA/SAGGA-compliant hardware.
Coastal / Corrosive Air (Garden Route & KZN coast)
- Specify marine-grade powder coating and stainless steel hardware.
- Silicone sealing and regular rinse maintenance schedule.
- Prefer top-hung to shed rain and protect the opening edge.
Cooler Regions / Winter Comfort
- Double glazing with argon fill (where possible) to improve U-value.
- Consider fixed lights alongside operable sashes to reduce drafts.
- Use EPDM gaskets and close tolerances for best airtightness.
Quick Match Guide
- Max airflow, modern look: Sliding / top-hung
- Strong seal + wind resistance: Side-hung
- Thermal comfort: Double glazing (see Double Glazing)
- Coast: Marine-grade coat + stainless hardware
