Aluminium windows have a design life of 30 years. This is because, aluminium

is considerably more resistant to the outside elements compared to other frames. Aluminium also has a high strength-to-weight ratio, making them more resilient and less  susceptible to accidental damage.



While also being durable, aluminium windows have the added advantage of being easy to maintain.  Available in all popular frame styles. Fixed, casement, tilt & turn, flush sash, sliding sash, bay and vertical sliding.

UPVC Windows

Supply only

We supply a wide range of uPVC windows available in all popular frame styles. Fixed, casement, tilt & turn, flush sash, sliding sash, bay and vertical sliding.


The robust and resilient built of uPVC windows makes them exceptionally durable against tensile stress and wind impacts while their ability to resist corrosion, and temperature variations makes them long lasting.


uPVC Windows are a low-maintenance, long lasting and secure choice for developers. When equipped with advanced multi-locking systems, uPVC windows also provide enhanced security against forced entry.
