New acoustic liner ensures great acoustics and easy handling


B


oth a building’s users and its developers have a good reason to get excited about the new Troldtekt Plus 25 panels. This specially developed acoustic panel sets a high standard for both sound absorption and building effi ciency. Danish manufacturer Troldtekt


A/S introduces yet another innovative solution for the construction industry: Troldtekt Plus 25 is an acoustic panel that combines high sound absorption with signifi cant practical advantages such as low weight, space-saving design and low overall costs.


In practice, Troldtekt Plus 25 is a two- layer panel but only 25 mm thick, just like Troldtekt’s traditional single-layer panels. A special acoustic liner made of non-woven acoustic fl eece is applied to the back of the panel and ensures high sound absorption. As a suspended ceiling, Troldtekt Plus 25 has a so-called alpha value of 0.9 (w = 0.90), which means that it can achieve Class A sound absorption at a suspension depth of 200 mm. The fact that the panel excels in the low frequencies (125-250 Hz) makes it perfect for applications such as classrooms and meeting rooms. The acoustic fl eece itself is so thin that the panel measures and weighs the same as


a traditional 25 mm Troldtekt


acoustic panel – without a backing layer. This makes it signifi cantly easier to stack, cut, lift and assemble on site. With a thickness of only 25 mm and a weight of 11.5 kg, Troldtekt Plus 25 offers signifi cant logistical and practical advantages including


transportation, storage and installation. Depending on the panel specifi ed, reaction


to fi re is classed in accordance with EN 13501 as B-s1,d0 or A2-s1,d0 respectively. Cradle to Cradle Certifi ed®


at Gold level,


Troldtekt wood wool acoustic panels are manufactured using wood from certifi ed forests (PEFC/09-31-030 and FSC®


C115450)


and can contribute positively to a building’s BREEAM, WELL or LEED points. Samples, case studies and technical guidance are available from Troldtekt’s

Advanced moveable wall systems maximise space fl exibility at leading London fi rm


At the offi ces of Russell Reynolds in London, Style worked with contractor, Thirdway, to add adaptability to the main meeting room whilst contributing to an interior decor that delivers the ‘wow’ factor demanded by the client. A Skyfold moveable wall gracefully descends from the ceiling cavity at the touch of a button, allowing two smaller meeting rooms to be quickly created. Dividing the meeting area from the large open-plan breakout space, a fully automatic Dorma Huppe Varifl ex glass wall system, fi nished with Interpon Bronze frames, runs the entire length of the room. With exceptional acoustic ratings of 59 dB for the Skyfold and 52 dB for the Varifl ex, concurrent meetings can take place entirely undisturbed, while the glass moveable wall maintains a light, open plan feel. Style’s combination of Skyfold and Varifl ex moveable wall systems allows the room to be reconfi gured in several different ways, depending on the daily meeting schedule. The quality of the fi nishes ensures both walls add to the overall interior design of this very stylish offi ce space.

A comprehensive Mapei system has been used in the refurbishment of tiled and rendered areas at Kentish Town Underground Station. The application, carried out by Cleshar for Transport for London, forms part of an upgrade of the north London Tube station. The specifi cation included Mapei mortars, adhesive, grout, sealant and UltraCare maintenance products – featuring very low VOC EMICODE: EC1 Plus formulations – and protective paint system, Silancolor Tonachino Plus. An interchange station located in the London Borough of Camden, Kentish Town Underground Station had 1,786,866 entries and exits in 2023/24, making it the 293rd most used, out of 2,581 stations in Great Britain. In addition to an upgrade of escalators, removal of a redundant ticket offi ce and realignment of ticket barriers, other essential works at Kentish Town include deep cleaning, painting, installation of new wall tiles, and new signage. Mapei systems played a key role in the refurbishment works, being used to repair wall surfaces through tunnels, install ceramic tiles and protect the fi nished render.
