Window materials to consider in SG13
uPVC — most popular and lowest cost. Excellent insulation, no maintenance, 20+ year lifespan. Suits any property style.
Aluminium — slim sightlines and a modern look. Costs more than uPVC but lasts 40+ years. Best for contemporary extensions and large picture windows.
Timber — traditional appearance, often required for listed properties or conservation areas. Higher cost and needs periodic re-sealing or painting.
Composite — timber inside, aluminium or uPVC outside. Combines the look of wood with low maintenance. Premium price point.
