Client Leading property developer

On what is the oldest continually industrialised site in the UK and close to Leeds city centre, the Kirkstall Forge mixed-use development will comprise 1050 new homes, 300,000sq ft of high quality offices and 100,000 sq ft of leisure, shops and restaurants. The first phase includes Number One, Kirkstall Forge, an award-winning, seven storey Grade A office building.

For the office entrance suites, Planet installed the LOFT54 industrial framed double-glazed partitioning system in banded, crittall style whilst offering an impressive 45 dB(Rw) acoustic rating. To provide a unified appearance, these were complemented by integral LOFT IsoPro 42 double-glazed doors with a 42 dB (Rw) rating for single doors and a 36 dB(Rw) for double doors. As part of the security requirements, these doors feature concealed electric locks.

Within office suites, the design of a number of meeting rooms saw Planet providing the PURE54 frameless double-glazed partitioning system which was installed in conjunction with the IsoPro 36 single-glazed doors. The scheme also featured Planet’s industrial style LOFT FireTec fire-rated door product in the corridor area. Incorporating electric hold-open floor springs, the doors are linked to the fire alarm system which keeps fire protection doors open in the event of a fire. Offering superlative fire performance of up to 60/60 (Ei60) fire rating, FireTec doors require minimal framing, whilst allowing for maximum transparency and stunning aesthetics.

    Project insights.

    To complete the package, reeded manifestation has been applied to a number of glazing sections whilst PPC black steel-faced plasterboards have been installed within the LOFT54 framework to provide specialist signage and to mount access control panels. To allow for movement, +/-25mm deflection heads were required above all screens and doors. Planet has played its part in the creation of a stunning and inspirational office workspace which ensured acoustic, aesthetic and fire performance requirements were met on this landmark office development.

    As part of their complete package, Planet were able to offer the desired crittall style glazed partitioning which successfully combined acoustic performance and design aesthetics. The team from Planet were very accommodating on-site, delivering a high quality solution that met the client and architect’s brief. We look forward to working with them again on future projects
