Window and Door Styles

uPVC Double-Glazed Windows and Doors We Install

Every home has different requirements. Redwood supplies and installs made-to-measure uPVC windows and doors based on your property, available space, ventilation needs, access and preferred appearance.

uPVC Casement Windows

Casement windows are a popular choice for residential properties. They can combine fixed panes with sections that open from the side or top.

Each window can be configured to suit the size of the opening, the ventilation required and the exterior style of your home.

Sash and Flush Sash Windows

Vertical sliding sash windows provide the traditional appearance of timber sash windows with the practical benefits of modern uPVC frames.

For a cleaner, more streamlined look, flush sash windows sit level with the outer frame when closed.

Tilt-and-Turn Windows

Tilt-and-turn windows can tilt inward from the top for ventilation or open fully from the side for easier access and cleaning.

They are especially useful where outward-opening space is limited..

uPVC Front, Back and Side Doors

Our made-to-measure uPVC entrance doors are available in panelled, partially glazed and fully glazed designs.Side panels and fanlights can also be included to suit the layout of your existing entrance.

French, Sliding Patio and Bifold Doors

Glazed doors can create a wider, brighter connection between your home, extension, patio or garden.

French doors open on hinges, patio doors slide along a track, and bifold doors fold and stack neatly to one side of the opening.
