Our PVC-U Products

Low maintenance

PVC-u will never flake, peel, rust or rot and is therefore relatively maintenance free.


Unlike wooden frames which usually require frequent treatment or re-painting. PVC-u windows will occasionally need washing down with hot soapy water.

PVC-u is also more environmentally friendly than timber as it can be recycled over and over again to produce new windows. 

Thermally Efficient

Standard windows are 28mm thick insulated double-glazed units for low-e energy rating and thermal efficiency.  We also supply a 36mm triple-glazed option.  


Reinforced with 100% recycled PVC-u bars for added strength and increased thermal performance.

High Durability

Glazing beads are fitted internally for extra security and opening frames are fully weather-stripped.


Modern PVC-u frames have a smooth, consistent and reliable operation.
