FAQ

The range includes made-to-order timber windows and doors, timber-aluminium windows, selected window constructions for historic buildings, and rustic or aged-look joinery. The catalogue also includes products for particular opening methods and applications. The construction should be selected to suit the dimensions, the character of the building and the project requirements, rather than by profile name alone.

For an initial joinery quotation, provide the opening sizes, quantities, preferred divisions, opening method, glazing and finish. Photographs, drawings or a window schedule are also helpful. This information makes it possible to identify a suitable construction and the points that require further agreement.

Traditional Polish frame windows have two sashes fitted to the frame: one opening outwards and the other inwards. Box windows use a different construction and should be specified separately. Rustic or retro windows are new joinery with an intentionally aged appearance; they are not automatically a reconstruction of a historic window or the repair of existing sashes.

Please provide photographs of the existing joinery and elevations, available drawings, dimensions, and details of the divisions, proportions and features that must be retained. Where the building is protected, include any conservation guidance already issued for the project. A manufacturer’s quotation does not replace any consent or approval required for the property. See also our windows for historic buildings.

A timber-aluminium window has a timber construction with aluminium cladding on the external face. The internal and external appearance, cladding colour, glazing, hardware and other specification details must be agreed in the quotation. A timber-aluminium window is not the same as a window made entirely from aluminium.

Ug describes heat transfer through the insulating glass unit, while Uw applies to the complete window. A lower value indicates better thermal insulation for the element being assessed, but Ug and Uw are not interchangeable. Compare values for the same, clearly defined window size and specification; the value relevant to an order should be stated in the quotation documentation. Learn more in our technology section.

Start with the required level of protection from external noise and the conditions at the installation site. Performance is affected by the window construction, glazing, airtightness, dimensions and correct installation. Any declared acoustic value must be confirmed for the offered specification — the profile name alone is not sufficient. See our acoustic window solution.

An opaque coating covers the grain and gives the surface the selected colour. A translucent or stain finish leaves the grain visible while adding colour. The final appearance also depends on the timber species and its natural variation, so the colour and finish sample should be agreed before the order is placed. Our technology section explains the finishing context.

Please provide the dimensions and quantities, divisions, opening directions, glazing, finish, colour and project location. Historic joinery also requires photographs, drawings and any available conservation guidance. In the quotation form, state whether the enquiry should include a survey, removal, installation or other additional work.

Pricing is project-specific. It is influenced by the construction, dimensions, number and shape of units, timber species, glazing, hardware, finish and service scope. A reliable timber window quotation requires at least a basic window schedule; the size of a single window is not always enough to compare different solutions.

Lead time depends on the type and number of units, the level of customisation, finish, material availability and the agreed service scope. The current lead time is confirmed in the quotation for the specific order. A general range shown on a website should not be treated as a binding production date.

The availability of surveys, removal, installation and related work must be confirmed for the project location and scope. Please state the location and required services in the quotation form. The offer will define the scope, responsibilities and conditions.

The guarantee period and scope depend on the product and are stated in the current documents supplied with the quotation or order. Correct installation, proper use and regular maintenance in accordance with the instructions are important for durability and compliance with the guarantee conditions.

There is no single renewal interval suitable for every window. Inspect the coating regularly and clean, maintain or renew it in accordance with the instructions. The required frequency depends on exposure to sun, rain and moisture, as well as colour, construction and previous maintenance. The condition of the coating — not the age of the window alone — determines when renewal is needed.

They are new joinery products whose timber surface is treated to create a rustic, aged appearance. This is a finish and does not automatically mean the restoration of an old element or a historic reconstruction. Technical performance depends on the selected construction, glazing and complete product specification. See our rustic timber windows.
