Perfect window. Perfect installation.
To be perfect, a window requires best-practice installation. For this, we at Finstral recommend the two-stage installation method with mounting frame: this frame is fitted during the wet construction phase and the window only installed when all the “messy” operations have been completed. This virtually eliminates any risk of damage to the window.

New-build homes and wholesale refurbishments are milestones.
Apart from shaping the architecture and daylighting of your home, the decision to install new windows will also dictate its energy efficiency for decades to come. Yet, many clients underestimate the complexity of the design process – which covers everything from correct window sizing for new-builds and good-practice installation to the appropriate choice of sunshading. With Finstral, you have an expert at your side that integrates all components into a holistic concept. Not only do we guarantee maximum design freedom, we also vouch for RAL-certified installation that rigorously eliminates any risk of later damage to new-build windows, e.g. through mould.
FAQ
What is the right time to install windows in a new-build?
Windows are traditionally fitted after completion of the building shell and roof, though prior to interior plastering and screed laying. To prevent any damage to the new windows, we recommend our two-stage installation method with mounting frame. This involves incorporation of the frame in the masonry at an early stage, with the finished windows only fitted at the very end during the “clean” construction phase. This virtually eliminates any risk of damage to the window.
Who is responsible for window measurement at the structural works stage?
For a new-build scheme, measurements should never be based simply on estimates or the sizes shown in drawings. Finstral tasks its own technicians or certified specialist partners to take the final detailed measurements on site. This is normally performed once the masonry has been completed and the so-called “datum line” (important reference level for flooring) has been marked out by the site supervisor. In this way, we can guarantee an inch-perfect fit for our custom-made windows.
How long is the warranty period for windows in new-builds?
The statutory warranty period applies. For further details, please visit: Warranties/certificates - Finstral Planner.
Do I need planning permission for new windows?
On a standard new-build project, the windows are already covered by the approved drawings. In case of major alterations or wholesale refurbishment, you will not normally need additional planning permission for the simple replacement of existing windows. Planning permission is, however, required for any significant changes to the size of window openings, the formation of openings in structural walls or works to listed properties.
