Important steps before you lay Regupol® 6010BA Acoustic Screed Underlay

Prepare the base floor. It is important that the base floor is clean (free from loose dirt and concrete dust), flat (within National Building standards +/-5mm over a 5m span) and where possible, dry.

Unroll the Regupol®. When the product is rolled up it stretches slightly. Unwind each roll where it
is to be installed and leave it for a few hours before measuring or cutting to length.

Laying Regupol® 6010BA Acoustic Screed UnderlayRegupol 6010BA Acoustic Screed Underlay Perimeter Strip

Regupol®6010BA perimeter strips must be installed first, with the dimpled face of the material butted against the perimeter walls. These strips can either be cut to the required width on site using a sharp knife and straight edge or pre-cut strips can be ordered individually.N.B. The perimeter strips should be at least 10mm above the finished screed. Excess material to be trimmed after the screed has set.

The Regupol® 6010BA Acoustic Screed Underlay must then be laid dimpled side down. Use a sharp knife and straight edge for cutting to size.

Joints to be butt jointed (both along and across the roll). Butt joints to be taped down using Regupol®Hi-tack tape.

Everyman Theatre

Noises Off at the Everyman Theatre, Liverpool

When a client envisions a major redevelopment project that will “allow the whole building to become a vibrant, creative hub, by day and night” acousticians, naturally, get a little bit nervous. To an acoustician, vibrant is just another word for noisy. As for creative? That’s just another word for chaos. When the client proceeds to announce that this vibrant, creative hub is to include an assortment of quiet and loud spaces, nervousness may turn to panic.

Such was the case with the £28 million redevelopment of Liverpool’s treasured Everyman Theatre. Alongside such vibrant and creative spaces as the theatre’s famous wraparound auditorium, basement bistro, cafes, bars, rehearsal rooms, workshop facilities and a bustling front-of-house are such noise-sensitive features as a recording suite, meeting rooms and a writer’s study. Add to this an anticipated footfall well in-excess of 100,000 each year, and the acoustic challenge becomes more demanding still.


Enter: The Seasoned Performers

The client, Liverpool and Merseyside Theatres Trust, brought in architects Haworth Tompkins, with their considerable experience of theatre soundproofing work, including the Bush Theatre, the National Theatre Studio, the Young Vic, the Ustinov Theatre, the Royal Court Theatre and the Chichester Festival Theatre. In tackling the various soundproofing issues, Howarth Tompkins worked with acousticians Gillieron Scott Acoustic Design. Gillieron Scott have an equally impressive roster of theatre soundproofing projects, including the Apollo Theatre, the Royal Shakespeare Courtyard, the Almeida, the Chaucer Theatre and the Theatre Royal.


Enter: Regupol 6010BA

The decision was made to specify 900m2 of CMS Danskin’s Regupol 6010BA under screed acoustic insulation material, with its potential to provide 42dB of impact sound insulation and 62dB of airborne sound insulation. Just as importantly, with a maximum load bearing capacity of 50kN/m² (5000kg/m²), Regupol 6010BA is designed to provide acoustic insulation beneath screed in areas where extreme loads and heavy traffic volumes are anticipated. As with all of Regupol’s acoustic under-screed products Regupol 6010BA is designed and expected to last the lifetime of the application. This is particularly important when heavy loads are a factor as compression over time can measurably reduce the acoustic effectiveness of a soundproofing material.

Just like architects Howarth Tompkins and acousticians Gillieron Scott, CMS Danskin are no strangers to the world of theatre. Regupol and a variety of other products have been successfully deployed in theatre soundproofing projects including The Globe Theatre, the Chichester Festival Theatre, the Royal Shakespeare Theatre and the Edinburgh Festival Theatre.

Regupol 6010BA also contributed to the project’s BREEAM ‘excellent’ aspirations. Regupol 6010BA is manufactured from a recycled rubber crumb and has Zero GWP (Global Warming Potential) and Zero ODP (Ozone Depletion Potential).
