Materials Available for Casement Windows

Choose the right window frame material


For most homeowners, uPVC keeps costs low while performing reliably year after year. The weather-resistant plastic requires little maintenance - just an occasional clean with soap and water keeps uPVC looking fresh.

Versatile uPVC suits traditional or contemporary homes. Though slightly less durable than aluminium over decades, uPVC delivers hassle-free, cost-effective protection.

Aluminium Double Glazing Installers Hampshire, Berkshire, Surrey, Dorset & West Sussex


With the highest sustainability, security, style, and viewing potential, aluminium window frames bring unique advantages. The durable, low-maintenance nature provides long-lasting, hassle-free performance.

For a more sustainable, ethical window with several custom styling possibilities, superior views, and military-level robustness, aluminium frames are the superior choice.

Hampshire, Berkshire, Surrey, Dorset & West Sussex Wooden Window Company


Wooden window frames were the most common choice before the introduction of low-cost uPVC. Wood has the lowest heat conductivity of the common frame materials, whilst also being environmentally friendly.

Listed buildings often require a timber-look window installation, however modern aluminium and uPVC can perfectly mimic the appearance and options of wooden windows.
