Windows, frames and glazing

An enquiry can cover one window, several openings in a property or glazed elements identified in the design, including glazed doors where specified. Identify what you would like to install, replace or retain and its relationship with the indoor and outdoor spaces.

For replacement work, the existing frame, condition of the opening and adjoining elements affected need to be understood. In a new building or extension, installation should be coordinated with the dimensions and junctions defined in the design. The proposal should describe the frames, glazing, opening arrangement and components included, together with removal, preparation and the agreed finishing work.

PVC and aluminium are options to consider within your enquiry. To prepare the selection, identify the openings, intended appearance, colour and any frame references already established for the building. If there is a project specification, send it with the drawings.

Comparison should start from identified systems, with their profiles, components and documentation. The material name does not, by itself, describe the complete assembly to be installed. Objectives for comfort, use or integration with the façade should be translated into requirements for the actual solution, without attributing the same result to every PVC or aluminium window.

Explain how you use each room and the limitations of the current windows. The choice of fixed and opening sections and how they operate should be coordinated with the available space, furniture, controls and access needed for use and cleaning.

When defining the glazing, identify the daylight, privacy and comfort objectives you would like to consider. If thermal, acoustic or other requirements are specified in a design, these should accompany the enquiry and be related to the documentation for the proposed system. The selection should identify the frame and glazing assembly, without using one feature as a promise of performance for the installed window.

Preparation should consider thresholds, sills, walls, finishes and any shutter boxes or other adjoining elements. Send photographs from inside and outside and identify what you would like to retain. Available measurements help prepare the enquiry; dimensions for supply and installation need to be confirmed within the defined scope.

Where replacement accompanies façade refurbishment or insulation work, junctions should be coordinated with those interventions. The proposal should define internal and external making good and repairs to finishes. If there are signs of water or deterioration around the window, describe them: deciding to replace the frames does not, by itself, establish the cause of every observed problem.

The proposal should identify who supplies the elements, the reference dimensions and specifications and the installation work included. If you have already bought the frames or appointed another supplier, send the documentation so that responsibilities and installation conditions can be clarified.

The arrangements should consider removal of the existing elements, access, occupation of the property and associated finishes. At handover, the review should refer to the agreed elements, operation, components and making good, identifying any outstanding points. Operating and care guidance and the product documentation planned should be clear within the agreed scope.

Send the property's location and photographs of each opening from inside and outside, where available. Include:

• The number of elements and known approximate dimensions.
• Existing materials and opening arrangements.
• What you would like to replace, retain or alter.
• Preferences for material, colour, opening and glazing.
• Available designs or specifications and requirements to be considered.
• Planned façade, insulation or renovation work.
• Access arrangements and use of the property.

If you have not yet selected a system, explain your priorities and the problems observed. The enquiry can start from these needs, identifying what remains to be confirmed before supply and installation are defined.

• External thermal insulation — ETICS

  Coordinate window junctions with an external insulation intervention.

• Façade refurbishment

  Coordinate frame replacement with work to the existing façade.

• Thermal and acoustic insulation

  Consider internal insulation work related to the enquiry's objectives.

We welcome enquiries in Lisboa, Oeiras, Cascais, Sintra, Amadora, Odivelas and Loures. Availability and the feasibility of the work are assessed for each enquiry.
