Beautiful Timber Windows

Crafted By Hand

High Performance Flush Casement Timber Windows

Our high performance flush casement timber windows offer a modern approach to the traditional style of window commonly found throughout Great Britain.

The simplistic design of these windows effortlessly hides the modern features currently available on the window market. They are able to compliment both a modern or period home alike, whilst behind the scenes you can be confident that the windows will not only stand the test of the British climate, but also provide sufficient security for the modern day. This is done by the addition of a high performance rebate for weather protection, using concealed friction hinges and multi-point locking systems, yet still allowing the casements to sit in line with the frame itself, as with the conventional flush casement timber window. We offer both side and top hung variations of our high performance flush casement timber window.

These handcrafted windows are made from the highest quality sustainable timbers. We only purchase timber from suppliers who offer FSC (Forest Stewardship Council) or PEFC (Programme for the Endorsement of Forest Certification) certified products. We also insist on using completely solid timber (not engineered or veneered components). Whilst we are able to offer any timber legally available in this country, we predominantly use Sapele hardwood, with its fine-knit grain giving good durability for external joinery use; and joinery grade European redwood, which has fewer knots than some lesser grades of softwood.

Our high performance windows have undergone and passed rigorous testing in accordance with BS7412: Air and water permeability requirements. The results showed that the windows exceeded the level of resistance required by the test, ensuring that they can more than adequately cope with anything the British weather might throw at them.

The range of ironmongery we use as standard at TimberPlus, offers a very high level of security for our high performance flush casements, with added security features available should you require them. Please ask one of our team at the point of preparing your quote, to ensure that we can meet or surpass your requirements. Our high performance windows have undergone testing in accordance with PAS24:2012 (known formerly as BS7950) : enhanced security requirements for doorsets and windows in the UK. We passed the standards set whilst using our standard ironmongery. For further information on our test results, please click here.

At TimberPlus, we are so confident in the quality of finish of all our joinery items, that we don’t feel the need to ‘cover-up’ our workmanship with a paint or stain finish. We therefore, leave all of our items in the raw timber state as standard, whether they be in hardwood or softwood. That said, we also understand that some of you would prefer to leave the finishing to experts, which is why we are able to offer you a range of finishes from just priming through to full factory spray finish and factory glazing in your choice of colour(s) as an added extra, giving you peace of mind that all you are left to do is fix the window in place. Please note: if you are upgrading to a full factory finish including pre-glazing, we advise you to make sure this will not cause difficulty when it comes to fitting your windows (see our guide on installing timber windows).
