FAQs, facts and tips
World Group Casement Windows

Casement Windows

The practical, versatile window most houses need. Styles, finishes and ironmongery to suit, with security that goes past the usual tests, and a warmer U-value than most local makers.

Tilt and Turn Windows from World Group

Tilt & Turn Windows

Easy to clean, a fire escape when the opening is large enough, and ventilation you can set. Tilt in for airflow, or turn the sash in and reach both sides of the glass.

Sliding Sash Windows from World Group

Sliding Box Sash Windows

The classic look, without the draughts and poor security of an old timber sash. Made here, not bought in, with a run-through horn and an anti-jemmy bar.

Flush Windows from World Group

Flush Windows

Keep the traditional timber look. Gain the warmth, the seals and the security of PVC, in colours that include the woodgrains.

Shaped Windows for all shapes and sized from World Group

Shaped Windows

For a house that is not like the one next door. Arches, circles and one-off shapes, colour-matched so the special window still belongs with the rest.

Double or triple glazing?

Double vs triple glazing

Double glazed: U-value 1.2

Two panes with an argon-filled gap and an energy-coated pane. Building regulations ask for 1.6; many local makers offer 1.4 or 1.3. It's about 65% of what we install, and does a good job for most homes.

What would it save?

Triple glazed: U-value 0.8

Three panes, two argon-filled gaps and two coated panes: warmer, quieter, and less prone to condensation inside. Ideal on a busy road, or for the best possible return.
