Granada’s secondary glazing ensures sound night’s sleep for London hotel guests

  • 11 Nov 2019

Guests at a central London hotel located seconds away from Fleet Street can enjoy a peaceful and comfortable night’s sleep thanks to Granada Glazing.

This is courtesy of bespoke aluminium secondary glazing, manufactured and installed by the company.

Granada was approached to devise the optimum solution to lower external noise levels and improve the thermal efficiency of the 204 guestrooms and suites in the Neo-Georgian four-star Apex Temple Court hotel.

The hotel sits within the inner Temple conservation area of the City of London. Where primary windows cannot be changed or are retained to keep a building’s character, secondary glazing is an effective and efficient way to enhance thermal performance and block out noise.

These are vital requirements within the hotel and leisure sector, as hoteliers are acutely aware of the need to make their guests’ stays as comfortable as possible.

At the start of the project, Granada supplied and installed a test unit in the most affected room. An Apexdirector who resided in the treated room for several nights was delighted by the substantial reduction in noise and the discreet appearance of the secondary glazing.

The success of the test unit led to Granada manufacturing and installing in excess of 320 secondary glazed units, including horizontal and balanced vertical sliders to match the function and style of the existing primary windows.

Some frames were arched to follow the contours of curved windows. Toughened low-E 6mm glass was specified for greater thermal efficiency. This type of glass is often the best choice, as it reflects heat back into the room, reducing heat loss by as much as 65%.

Post installation, the hotel noted substantial energy savings and a decrease in noise issues. As a result of the effectiveness of the installed secondary glazed units, Granada Glazing is working with Apex to replicate the noise reduction and thermal benefits for their other hotels in London.

At the Apex City of London Hotel, Granada Glazing designed, manufactured and installed bespoke secondary glazing in the ground floor conference room to combat noise issues from the busy road outside.

The hotel had received complaints from corporate guests about the noise levels and needed a solution to keep the room quieter.

Brian Tapson, Apex General Manager, commented: “The secondary glazing looks amazing. Since it was installed in the conference room, it does diminish the noise altogether and all of those complaints have now gone. We don’t get any problems at all. It’s excellent and definitely works for us.

“The service from Granada Glazing has been great too. When we call the company, they come back to us promptly. They’re very reliable and get the job done.”
