Frequently Asked Questions
Expert answers to warm edge vs aluminium spacer questions
Warm edge spacers use materials like stainless steel or composite materials that conduct less heat than aluminium. This reduces thermal bridging and improves the overall U-value of the glazing unit.
Yes, warm edge spacers significantly reduce condensation risk by keeping the glass edge warmer. This prevents the cold spots that cause condensation to form around window edges.
For Bishop's Stortford homes, warm edge spacers typically add £10-20 per window but can reduce energy bills by £30-50 annually per window, providing payback within 2-3 years.
Warm edge spacers can improve whole window U-values by 0.1-0.2 W/m²K compared to aluminium spacers. This represents a 5-10% improvement in thermal performance.
High-quality warm edge spacers have similar lifespans to aluminium spacers (20+ years). Modern composite spacers are highly durable and maintain their performance throughout the window's life.
Visually, warm edge spacers may appear darker (black or grey) compared to silver aluminium spacers. However, the performance difference is more important than the aesthetic difference.
