Timber Sash Windows London – Key Features

Classic Design with Customization

Timber sash windows are distinguished by their characteristic glazing divisions, which can be tailored to the building’s style (e.g., Viennese or applied glazing bars). Available in an extensive RAL color palette or wood stains that highlight the timber’s grain, they complement both traditional and modern facades.

High-Quality Materials

Manufactured from carefully selected timber such as pine, oak, or meranti, these wooden sash windows are protected with eco-friendly lacquers or oils. The wood is impregnated to ensure resistance to moisture, UV rays, and varying weather conditions.

Excellent Thermal Insulation

Available with frame depths of 146 mm and 150 mm, these wooden sash windows in London support double or triple glazing units, achieving high energy efficiency. For special requirements, single glazing options are available for conservation areas or listed buildings.

Smooth and Convenient Operation

The counterweight system (traditional with lead or steel weights) or modern spring mechanism ensures easy lifting and lowering of sashes, even for large and heavy structures. Optional sash position locks allow precise ventilation control.

Security and Durability

Equipped with anti-burglary hardware (PAS 24) and options for toughened or laminated glass, these double glazed timber windows enhance protection against break-ins.

Wooden Box Sash Windows London – Precisely Tailored to Your Project

We process every order based on technical documentation or field measurements of openings. We take into account the width, height, sash configuration, and details such as glazing beads and muntin proportions. For projects in townhouse developments or for additions to single-family homes, it is important to maintain consistency with the existing facade. Therefore, before production, we confirm all parameters and submit shop drawings for approval.

We work with both construction companies and private investors. We provide technical support during the planning stage to minimize the risk of installation errors and accelerate project delivery.

Sash Windows Timber – How They Work and Safety

The movement of the sashes is vertical, using a counterweight system with steel or lead weights, or a spring mechanism. Proper balancing makes it easier to lift even larger glass panels. Position locks can be used to stabilize the sash at a selected height.

Safety glass comes standard. Solutions that meet PAS24 requirements are available on request. This configuration enhances protection against break-ins in residential buildings and for projects undertaken by smaller real estate developers.
