Looking for sash window replacement in Slough? S&K Glazing has been installing across Berkshire for over a decade. Sliding sash windows are the architectural signature of British period properties — Georgian, Victorian, and Edwardian terraces, townhouses, and cottages. For Slough properties near Heathrow Airport (LHR), we can specify acoustic-grade glass to reduce aircraft noise alongside thermal performance.
Sliding sash windows are the architectural signature of British period properties — Georgian, Victorian, and Edwardian terraces, townhouses, and cottages. Original timber sashes often suffer from rot, draughts, rattle, and single-glazed inefficiency. S&K Glazing manufactures and installs replacement sash windows that match the original sightlines, glazing bar layouts, and sash horn profiles, but deliver modern U-values from 1.3 W/m²K and acoustic reductions up to 42dB. Available in engineered timber or slim-profile uPVC for conservation areas where uPVC has been approved.
Slough sits directly under Heathrow's western flight paths — extreme aircraft noise affects nearly every property in SL1, SL2 and SL3. Our acoustic glazing is the dominant install locally. Many properties qualify for Heathrow's noise insulation grant scheme.
For heritage and listed-property work in Slough, planning constraints frequently dictate the spec — we work within Berkshire council's conservation area rules and listed-building consent requirements, using putty-glazed timber sashes, slim-sightline secondary glazing systems that sit invisibly behind original primary glazing, and steel-window restoration for Crittall-style frames. Most commonly we're working across SL1, SL2 and SL3 postcodes. We prepare the heritage statement and Building Regulations submission alongside our quote where it's needed for South East conservation areas.
We measure the original sash, photograph architectural details (horns, beading profiles, glazing bar widths) and confirm conservation status with your local authority where applicable.
Each replacement sash is manufactured to your exact original dimensions and profile. Timber units use engineered redwood or accoya with factory micro-porous paint. uPVC units use slim heritage profiles.
Installation works elevation by elevation, typically 1-2 sashes per day. We retain original architraves and reveal mouldings wherever possible.
