30 Euston Square is a stunning Grade II* Listed building dating back to 1906. Maintaining the legacy of the health related professionals who have occupied the building since it was constructed; in 2010 the building was acquired by the Royal College of General Practitioners (RCGP). Selectaglaze has a long standing relationship with RCGP and has carried out a number of installations to different areas of the building over the years. Located in an extremely busy part of London and having only single glazed steel or timber casements, thermal and noise insulation needed to be upgraded to improve the environment for the users. The option of double glazing was explored for all the treatments, but as the building is Listed, the original windows had to be retained. The State Room on the top floor is often let out for private functions, yet suffered from noise ingress through the beautiful roof lights spanning the length of the room. Side hung casements were specified and installed which meant full access was maintained for cleaning and maintenance of the roof lights and also gave an uninterrupted view of the original glazing. On a few of the lower floors there are study rooms where GP members can stay when they are on College business. Secondary glazing has been installed to prevent noise from passing traffic. The lower floors contain examination rooms, where around 3,000 GPs a year take their final assessments. These rooms required optimum noise reduction to enable complete concentration for students who were near to gaining their medical qualifications. A mixture of units were installed, including vertical and horizontal sliding units and side hung casements. The local area has changed dramatically in recent years, with Euston Station set to become the end point of the new HS2 high speed rail link. In 2016 Selectaglaze was approached to install secondary glazing to areas of the RCGP building on Stephenson Way and Euston Street to help combat any noise from the HS2 Enabling works.  Works were carried out over a number of floors to a vast number of openings, creating quiet reflective spaces for those working in the offices.
