ACoustic Rated
Acoustic rated access panels and riser doors tested to BS EN ISO 10140, with sound reduction up to 48dB Rw.
Lead Time: 3-5 working days | Bespoke: Made to measure as standard
An acoustic rated access panel is a hinged or removable panel that has been independently tested and certified to reduce the transmission of airborne sound through walls and ceilings. Acoustic rated access panels, riser doors and loft hatches are designed to maintain the sound insulation performance of the surrounding construction, preventing noise from travelling through service openings and compromising the acoustic separation between rooms.Acoustic performance is measured using the weighted sound reduction index (Rw), expressed in decibels (dB). The higher the Rw value, the greater the sound reduction. Rapid Access acoustic products achieve ratings from 36dB Rw up to 48dB Rw, tested to BS EN ISO 10140 at an independent UKAS accredited laboratory. Many of our acoustic products are also available with combined fire ratings, providing dual performance for projects that require both sound insulation and fire compartmentation.

UNDERSTANDING Sound rating
Acoustic ratings use two key metrics, laboratory performance and field performance. Understanding the difference helps you specify the correct product.
Tested to BS EN ISO 10140Rw is the weighted sound reduction index measured under controlled laboratory conditions. This is the standard metric used by manufacturers to classify the acoustic performance of individual building elements. Laboratory testing isolates the product from flanking transmission, giving a repeatable baseline measurement that allows direct comparison between products. All Rapid Access acoustic ratings are expressed as Rw values.Access Panels: up to 48dBRiser Doors: up to 45dB
Measured to BS EN ISO 16283-1DnT,w is the standardised level difference measured on site between two rooms. This accounts for real-world factors including flanking paths, junctions, and construction quality. Field values are typically 5 to 10dB lower than laboratory Rw values. Building Regulations Approved Document E sets minimum DnT,w requirements for separating walls and floors in residential buildings. Specifying products with a strong laboratory Rw rating provides a margin of safety to achieve the required field performance.Part E minimum: 45dB DnT,wTypical site loss: 5 to 10dBour acoustic range
Acoustic rated options are available across our access panel and riser door ranges, in metal faced, tile faced and plasterboard faced configurations.
Applications
Any building where sound insulation between spaces is specified will benefit from acoustic rated access panels and riser doors.
