Timbertherm's Windows are the right choice.
Keeping style and security in mind, our sash windows incorporate modern, concealed safety features and are supplied as standard with insurance compliant, key-lockable fasteners. With customisable features available, our windows can be designed to suit your project’s needs, while providing secure locking systems and optional security features, such as child locks and restrictions..
Custom Design & Bespoke Features
We offer a multitude of customisable and bespoke features so that our windows can be designed to match any existing style. With options like Georgian bars and swept or arched styles available, we aim to meet the needs of your project.
As standard, all of our sash windows use high-performing, Argon gas filled, double-glazed, sealed units. This means our products achieve low energy u-values, which can be upgraded by using coated glazing.
To achieve a durable and superior finish on our products, we fully immerse the product in primer before painting with a spray system, to eliminate any potential brush-marks. Our finishes are custom mixed to match any paint or stain specification suitable for your project.
We only use stable, engineered timber - proven to be much more stable than solid wood. Any natural defects, such as knots and sap, are removed from the wood to avoid bleed-through later on, and the timber is laminated with opposing grain to avoid any warping or twisting.
Our unique profile allows for extremely high weather-sealing all around our sash windows to avoid heat loss and improve efficiency, while holding the product securely to prevent any rattles or movement.
