Our Services

At Keystone Supplies, we specialise in a wide range of window and door services. Our offerings include:

• Timber Windows: We supply and install high-quality timber windows that provide a warm and inviting aesthetic. Timber's natural insulation properties help maintain a comfortable indoor environment while reducing energy costs.

• Aluminium Windows: Known for their sleek and contemporary appearance, aluminium windows offer a versatile alternative to traditional timber or UPVC. They are durable, low-maintenance, and resistant to corrosion.

• Timber Effect UPVC Windows: Timber effect UPVC replicates the natural grain and texture of timber, providing a classic, elegant look that complements various architectural styles. It is exceptionally low-maintenance, requiring no painting or staining.

• Aluclad Windows: Aluclad windows represent a blend of aluminium and timber, resulting in a versatile and high-performance option for modern construction. The exterior is crafted from robust and weather-resistant aluminium, providing a durable shield against the elements.
