Choosing between PVC windows and aluminium windows often comes down to what matters most: thermal efficiency, design, durability, and budget. Both materials can deliver excellent results when paired with the right profiles and glazing—but they perform differently depending on the application and the building type.

PVC windows are known for strong thermal insulation, helping reduce heat loss in winter and keeping rooms cooler in summer. This can support lower energy use and a more stable indoor temperature. They’re also a great option for homeowners who want a cost-effective upgrade without compromising comfort. Aluminium windows, especially thermal break aluminium systems, are ideal when you want slim frames, modern aesthetics, and high structural strength—perfect for larger openings and contemporary architecture.

To get the best outcome, focus on the full system: profile quality, sealing, installation, and double or triple glazing. If your priority is maximum warmth and energy efficiency, PVC is often the first choice. If you want a premium modern look with excellent performance, thermal aluminium is a top contender. At MK Aluplast, we help you choose the right system based on your home, your needs, and your budget.
