Full 70mm frame depth with 3mm wall thickness

Stronger thermal and acoustic performance and better fit with the existing plaster line than 60mm systems.

Multi-chambered construction

Gives the frame added strength and acts as an effective barrier to minimising heat loss through the frame.

Thermally welded frame joints

Unlike some lesser specified systems where the PVCu lengths are joined mechanically, fully welded frame joints give the window tremendous corner and structural strength.

High impact PVCu

The quality of the plastic compound used in the production of PVCu framed windows can vary. A high impact strength means the frame is of high quality, durable and ideally suited to deal with both the heat and the cold.

Load bearing baypole

Makes the framework of windows that have no support walls or heavy loads structurally sound. (Optional)

Galvanised steel reinforcements

Adds strength and dimensional stability. All woodgrain finish windows are fully reinforced as standard. (Optional on white)
