Mr H’s apartment is located on the top floor of a handsome white stucco period residence. On a property such as this it is vital that the traditional elements are maintained when carrying out any upgrading works. This is why Wandsworth Sash Windows is an excellent choice for such works. We have fantastic experience working with and improving on original windows and doors.
Given the historical importance of Mr H’s building it was necessary to submit a planning application with Westminster Council. The client took advantage of the Wandsworth Sash Windows bespoke planning service. This means we did all the necessary admin, form-filling and communication with the council.
We managed to get the planning application over the line and Westminster Council gave us the green-light to fit 4 new pairs of timber sashes into the existing box frames of the windows glazed with ultra-efficient Fineo glass. All sashes had a glazing bar design which matched the originals as this was a strict requirement of the council. This is called our Sash Replacement service. In conjunction with this service, we carry out full draught-proofing and overhaul of the sash windows. For a useful video explainer on our Sash Replacement service click this link – LINK.
The thermal-efficiency of a window is based on its U Value. The lower the U Value the better. It is estimated that a single-glazed sash window has a U Value of 4.0 – 4.5. The centre-pane U Value of Fineo glass is 0.7. This therefore represented a serious upgrade on the thermal insulation of Mr H’s windows.
