119 Ebury Street is situated in the central location of Belgravia. It was originally built as a single dwelling and was then renovated into a hotel. Recently it has been converted into three energy efficient apartments which led to 119 Ebury Street becoming the first Listed building to receive a BREEAM ‘Outstanding’ rating in the UK.

Grosvenor sought to create highly sustainable apartments which feature whole house ventilation and heat recovery; this was accomplished using the most recent engineering systems and low carbon technologies. Grosvenor asked Selectaglaze, based on their long working relationship, for an advanced secondary glazing solution.

Once the designs were agreed, Selectaglaze installed a total of 18 Series 25 units, which are a vertical sliding system with high capacity spring balances, ideal for treating larger windows that require thicker glass. The units were glazed with Pilkington Spacia, which is an evacuated sealed unit only 6mm thick with a centre pane U-value of 1.0. The secondary glazing treatment dramatically improved the overall U-value and assisted in achieving high airtightness levels.

Founded in 1966, Royal Warrant Holder Selectaglaze has worked on all types of buildings, from museums to new build hotels. Selectaglaze has a range of RIBA approved CPD seminars, which provide a better understanding of the applications and implications of specifying secondary glazing.
