Stone farmhouse with golden oak woodgrain windows and a cottage garden

Windows

Windows made for northern weather

A-rated uPVC and slim aluminium windows, made to the millimetre and fitted with care. Warmer rooms, quieter evenings and a house that looks its best.

Made to measure

The right window does three jobs at once

It keeps the heat in and the weather out. It keeps the house secure. And it looks as though it has always belonged there. Get all three right and you stop noticing your windows at all, which is exactly the point.

Our uPVC windows are made in our own factory from a 70mm, six-chamber profile with A-rated glazing as standard, and are usually ready in 5 to 14 working days. For slimmer frames and bigger panes, we supply and install thermally broken aluminium.

  • A-rated double glazing as standard
  • Key-locking handles and multi-point locks
  • Eight colours, single or dual
  • Fully fitted or supply-only

As standard

What every uPVC window includes

No optional extras dressed up as upgrades. This is the specification before you have chosen a thing.

A-rated glazing

28mm argon-filled double glazing with a low-emissivity coating and warm-edge spacers.

Built-in security

Multi-point shootbolt locking, key-locking handles and internally glazed frames.

Six-chamber frame

A 70mm profile with six insulating chambers, reinforced where the size calls for it.

10-year guarantee

Frames guaranteed against discolouring, warping and cracking, in writing.

Opening styles

Decide how each one opens

Which panes open, and which way, is up to you. These are the layouts we make most often.

  • Side hung

    Hinged at the side and opening outwards. The everyday casement.

  • Top hung

    Hinged at the top, so it can stay open in light rain.

  • Fixed

    A non-opening pane for the most glass and the best value.

  • Opener beside fixed

    One opening sash next to a fixed pane. The most common two-pane layout.

  • Top light over fixed

    A small top-hung vent above a larger pane, ideal for night ventilation.

  • Opener, fixed, opener

    A fixed centre pane with a side-hung sash on each side.

  • French casement

    Two sashes that open from the middle with no central post in the way.

  • Tilt and turn

    Tilts inwards at the top for air, or swings fully in for cleaning.

Drawn as seen from outside. The point of each triangle shows the hinged side. Almost any combination of these can be made in one frame.
