• The Timber Alternative

    Heritage Flush Sash Windows & Doors

    We offer the most authentic PVCu Flush Sash System on the market. While the Timberlook range is perfect for period properties, its minimal flush appearance is also ideal for contemporary projects.

What is Timberlook?

Wood-effect uPVC Flush Sash

We replicate traditional wooden windows and doors with energy-efficient uPVC profiles. Timberlook flush sash windows are mechanically-jointed, with the most authentic-looking square joints. This system mimics original, heritage flush casement designs but without the tell-tale diagonal welds used by our competitors.


The flush style is ideal for period or historic projects, and Timberlook windows are accepted in conservation areas by local planning authorities. The minimal aesthetic is also really popular in more modern properties and is often used in new build homes and contemporary house renovations.


Timberlook wood-effect flush sash windows and doors are more suited to modern living than timber windows. We can achieve the flush, period character look you want, with modern, thermally efficient materials.


They are undoubtedly more affordable than real wood frames and will significantly impact the comfort and appearance of any property. You can also forget about the costly and time-consuming maintenance typically associated with older windows, as uPVC does not deteriorate in the same way as wood.




Tradition & Technology


With unique patented Timberweld technology, Timberlook window sashes are not only completely sealed but have corners that closely resemble a carpenter’s traditional butt-joint – they are easily the most authentic-looking uPVC windows on the market.


The Timberlook Range

Both the Heritage Flush Window and Flush French Door systems are available in the same colours and finishing options, with a curated range of matching ironmongery, handles, and hardware.

New Windows in Conservation Areas

Satisfying Planning Permission


When we designed Timberlook flush sash windows, we were careful to consider all aspects of Article 4 Conservation Area guidelines for windows. We combined those design principles with the latest technology and most cost-effective materials.

Timberlook Flush Sash windows are modern, thermally efficient, and secure. They are beautiful to look at and, most importantly, preserve the traditional look of your property. Our flush casement windows are virtually maintenance-free, do not warp, swell, or flake like wooden frames, and will not need sanding or painting over time.


Timberlook Colours


The Timberlook range of colours and finishes has been carefully selected to complement and suit buildings of any age and is made from various materials – whether stone, brick, or mortar. With the exception of Smooth Anthracite Grey, our coloured foils have a subtle woodgrain textured finish to add extra authenticity.


Realistic wood effect finishes, such as Oak and Rosewood may be most effective for older properties or as new cottage windows, while anthracite grey windows match modern aluminium glazing. Dual-colour options help seamlessly blend with existing decor, or match a new scheme.

Finishing Touches


Timberlook flush sash windows come with contemporary handles as standard, but can be enhanced with our Premium Regency Furniture. This range includes Teardrop and Monkey-tail Handles, each with matching dummy stays. They are all available in a wide selection of material finishes that can imitate real ironmongery.

Windows have built-in security features, such as key-locking handles, sash locks, and child safety restrictors. Our furniture options further enhance the period looks, authentic frame proportions, and the chamfered edges that replicate putty lines.

New Build Projects



When specifying windows for any new build property, it is important to remember that they will need to conform to the latest stringent building regulations. This is applicable whether designing a single home or building an entire housing development.


Timberlook windows can be specified to the new Document Q standard, having passed independent testing. The glass and hardware we use are uprated, and windows are certified to PAS24 to satisfy the building inspectorate.

These are separate standards and should be specified when discussing your project with your local installer.
