Monarflex Monarsound FlameSafe Acoustic Insulating Scaffold Sheeting

Monarflex MonarSound FlameSafe Acoustic scaffold sheeting provides an effective system for controlling noise breakout on construction sites. It is ideal for use in minimising noise pollution in sensitive areas like schools, hospitals, residential areas etc.

MonarSound FlameSafe Scaffold Sheeting is made from a 5 ply composition incorporating a weather resistant LDPE flame retardant co-polymer that encapsulates a multifilament polyester grid which helps forms a weather protection layer. On the underside there is a thick 10mm PU fire retardant special sound absorbent foam. The sheeting is equipped with the unique Monarflex fixing eyelets for superior and long lasting fixing points .

Features & Benefits

Weather protection with additional acoustic absorption.
Suitable for long term projects up to 12 months.
Enhances security for the workers on the scaffold.
Serves as a climate shield to protect workers, machinery and open constructions against rain, wind, snow etc.
Ensures a stable working climate on the scaffold so deadlines can be respected regardless of the weather.
Protects surroundings from any inconveniences e.g. particles or building dust from sandblasting or water jetting from façade works as well as the noise levels associated with using high dB machinery.
Helps reduce noise levels and provides a climate shield in colder periods.
Tested to BS EN ISO 717-1 at Napier University for sound reduction.
Provides a climate shield on scaffolding not just against rain and snow but also against the effects of cold weather thanks to its high performance foam.
Flame retardant in accordance to DIN 4102-B1.
Tested as road noise barrier to BS EN 1793-2: 1998 and classified as B1 barrier.

Product Range

Monarflex MonarSound FlameSafe Scaffold Sheeting is made from a 5 ply composition with the top layers consisting of a weather resistant LDPE fire retardant co-polymer that encapsulates a strong multifilament polyester (PET) grid which forms the weather protection layer. On the underside there is a thick (10mm) PE fire retardant special sound absorbent foam layer that provides the “bounce” effect of the acoustic scaffold sheeting. The sheeting is equipped with the unique Monarflex fixing eyelets for superior and long lasting fixing points.

Durability

Monarflex MonarSound FlameSafe Scaffold Sheeting can be used for all types of long term projects up to 12 months. The combination of high quality components forms a tough and durable sheeting for very extreme working conditions i.e. sandblasting and water-jetting. By using Monarflex MonarSound FlameSafe Scaffold Sheeting you can meet deadlines and avoid economical surprises regardless of the weather and be safe in that it fulfils all relevant British Standards like BS7955:1999 and BS 8410:2007 in accordance with HSE requirements to sheeting performance.

Quality Assurance

Monarflex MonarSound FlameSafe Scaffold Sheeting is manufactured under a Quality Management System approved to ISO 9001: 2000 by BSI Quality Assurance.

Acoustic Assesments, Controls & Test Data

The Code of practice for noise and vibration control on construction and open sites BS 5228-1 2009, refers to the need to reduce noise levels, which local Authorities often requires to be considered as part of planning permission. By introducing a noise barrier that provides a at least 10 dB noise level at low frequency (like at 100 Hz) the general noise level is cut in half. Breakout noise is the biggest concern as this may account for 5-10dB noise level, so correct installation is as crucial as the noise reduction from the sheeting material itself. Breakout noise often comes from gaps or the actual installation fixings, so sealed fixing points or overlaps are crucial and Monarflex MonarSound FlameSafe acoustic scaffold sheeting provides these.

Acoustic Control

There are no guidelines for rating the performance of scaffold sheeting. However, BS EN-1793-2: 1998 “Road traffic noise reducing devices - Test method for determining the acoustic performance” allows for the method for categorising the sound reduction performance of barriers that may be used to control road traffic noise.

Application
Take care to overlap the lower sheet externally for weather protection. Fixing the sheeting to the scaffold must be done according to calculations, taking factors such as wind, building season and height of the surrounding buildings into consideration. We recommend the use of x 1 Monarflex Anchor & Strap fixing/m² but any fixing must be placed according to calculations for each project.
