Casement windows: Options in Devon and South Hams

Casement windows are the UK’s most popular window style, and for Devon homeowners, they offer a practical, good-looking solution whether your property faces the sea at Torbay or sits in a rural South Hams village. if you want draught-free, energy-efficient windows that work in almost any property type, a casement window is the place to start.

What are casement windows and why are they so popular in Devon?

A casement window is a glazed panel hinged at one side (or the top) that opens outward. The design is simple, which is exactly why it performs so well. When closed, the sash presses tightly against the frame seal to create an airtight, weatherproof barrier. When open, the full aperture is clear for ventilation.

Across Devon, from Newton Abbot to the South Hams coast, this style suits a wide range of homes. Period cottages in Kingsbridge, modern new builds in Paignton, and 1960s semis in Exeter can all accommodate casement windows with the right material and profile choice.

uPVC or aluminium casement windows in Devon: which is right for your home?

The two main materials available from Renaissance Conservatories are uPVC and aluminium. Each has strengths that suit different properties and priorities.

uPVC casement windows

uPVC is the most widely chosen material for replacement windows in the UK, and it’s easy to see why. The frames are low-maintenance, won’t rot, and hold their shape in wet Devon winters without needing painting or treating.

Renaissance Conservatories’ uPVC casement windows feature a four-chambered profile as standard, which traps air to prevent heat loss and keep draughts out. For properties that need even higher performance, a six-chambered profile is available and achieves an A+ Window Energy Rating (WER), the second-highest band on the scale run by the British Fenestration Rating Council (BFRC).

Key uPVC facts:

• Four-chamber standard profile; six-chamber upgrade available at A+ WER
• Colours include Rosewood, Chartwell Green, and a full range of foil finishes
• Georgian bars can be added for period properties
• Choice of chamfered or sculpted profiles
• All frames are lead-free and accredited to British and European standards
• Side-hung or top-hung opening configurations

Aluminium casement windows

Aluminium offers a slimmer sightline than uPVC, which means more glass area and wider views. The frames are strong enough to carry larger panes without needing thick profiles, making them a popular choice for more contemporary South Devon properties where clean lines and light matter most.

Aluminium is also the smart choice for coastal homes. Properties in Teignmouth, Salcombe, or anywhere on the South Hams coastline face salt air and wind that would degrade less resilient materials over time. Aluminium does not rust or corrode, and a simple wipe with soapy water is all the maintenance it needs year round.

Thermally-broken aluminium profiles prevent heat from conducting through the frame, keeping indoor temperatures stable regardless of the weather outside. Aluminium is also 100% recyclable, making it a sound choice for homeowners who want to reduce their environmental footprint.

Key aluminium facts:

• Thermally-broken profiles for year-round heat retention
• Rust and corrosion resistant; ideal for seaside properties
• Powder-coated finish available in any RAL colour
• Slim frames allow larger glazed areas and better views
• Advanced multi-point locking for improved security

Design options for Devon and South Hams properties

Devon’s housing stock is one of the most varied in England. Newton Abbot has terraces and Edwardian villas. The South Hams has thatched cottages, barn conversions, and modern waterside developments. The right casement window for a granite farmhouse near Totnes looks nothing like the right window for a 1990s new build in Ivybridge. Renaissance Conservatories offers a wide range of customisation to match any of these scenarios.

Colour and finish choices

White remains the most popular colour for uPVC casement windows, but it is far from the only option. Available finishes include Rosewood, Chartwell Green, Anthracite Grey, Cream, and various woodgrain effects. For aluminium, any RAL colour is available as a powder coat, including dual-colour finishes where the external face can be a dark contemporary tone and the internal face is white or light grey.

Profile and glazing bar options

Georgian bars can be added to uPVC frames to replicate traditional glazing patterns, giving a period aesthetic without the maintenance of genuine timber. Both chamfered and sculpted profiles are available, allowing the depth and shadow line around the frame to match the character of the surrounding property.

Glazing choices

Standard double glazing is included as the base specification. Upgraded glazing options can improve acoustic performance, which matters for homes near the A38, the A380, or the busier coastal towns. Argon-filled units provide better thermal performance than air-filled equivalents for no visible difference in appearance.
