Premier Inn chooses Granada’s secondary glazing for new Llandudno hotel

Secondary glazing manufactured and installed by Granada Glazing was specified to provide modern levels of comfort for guests at a new Premier Inn built on a Grade II listed former hotel site in Llandudno town centre.

The £12m redevelopment of the former Tudno Castle Hotel site comprises a 90-bedroom hotel, one restaurant and three retail/restaurant units and a gym/business unit. It opened in Spring 2022 following a protracted planning process and delays.

The Tudno Castle is a Grade II listed building built in the 1870s. It had been derelict since 2008 and six years later, planning permission was granted for the demolition of the building behind a retained façade and the erection of a new hotel and extension.

Work started in 2017 but had to be put on hold when partial demolition work of the structure revealed that the Grade II listed façade of the building was unstable. This meant that the developers Tudno Developments Ltd had to come up with revised plans which would allow the demolition of the Victorian façade followed by its reconstruction on a like-for-like basis.

Faithfully recreating the historic façade meant installing timber single-glazed sash windows which were treated with Granada Glazing’s latest high-specification secondary glazing range to reduce outside noise intrusion and improve the thermal efficiency.

A total of 46 units were installed – a combination of traditional-looking Balanced Vertical Sliders and Hinged Units – all with 6.4mm laminate Low E glass that reflects heat back into the rooms. Both products deliver 21st century standards of thermal and acoustic efficiency for single glazed primary original, or in this case, replica windows.

“Where double glazing cannot be installed due to planning regulations, secondary glazing is often the preferred solution. It offers a cost-effective and efficient solution in reducing external noise by up to 80% and improving thermal insulation by up to 65%,” says Robert Cottam, Granada Glazing Commercial Sales Manager.

“In establishments such as hotels, creating a warmer and quieter environment is essential for guests’ comfort and this is where secondary glazing scores very highly.”

Premier Inn’s initial plan was for a 63-bedroom hotel but after considering the best format for its guests, decided to add a further 27 bedrooms by occupying the vacant retail space in the development. Construction contractor Medlock FRB Ltd was appointed to add the new rooms and their site manager Martin Blundell has noticed the difference that secondary glazing has made.

“It has definitely made the rooms a lot quieter, and you can’t hear the traffic outside,” he observes. “The system looks very neat, and the Granada team did a really good installation job. The transoms on the window match the transoms of the secondary glazing so it doesn’t interrupt the look at all.”

Suitable for all property types, Granada’s slimline aluminium secondary glazing frames can be powder coated in over 200 RAL colours. Virtually invisible, they blend in with any interior décor. The Granada Glazing product range encompasses hinged, sliding, vertical sliders, including tilt back, and lift-out options.
