KNAUF GYPSUM PARGE COAT SET FOR MORE PART E SOLUTIONS
Knauf Drywall’s Gypsum Parge Coat – a key solution for Part E compliance in
residential masonry separating walls – has gained further approvals that allow its use in a
wider range of applications. After extensive on-site acoustic testing, Knauf Gypsum
Parge Coat has achieved Robust Detail status for use on cavity separating walls of dense
aggregate blocks (1,850-2,300kg/m3) and Besblock Star Performer general purpose
cellular blocks. This follows earlier RD approval for its use with medium density
aggregate blocks (1,350-1,600kg/m3).

KNAUF GYPSUM PARGE COAT SET FOR MORE PART E SOLUTIONS

Knauf Drywall’s Gypsum Parge Coat – a key solution for Part E compliance in

residential masonry separating walls – has gained further approvals that allow its use in a

wider range of applications. After extensive on-site acoustic testing, Knauf Gypsum

Parge Coat has achieved Robust Detail status for use on cavity separating walls of dense

aggregate blocks (1,850-2,300kg/m3) and Besblock Star Performer general purpose

cellular blocks. This follows earlier RD approval for its use with medium density

aggregate blocks (1,350-1,600kg/m3).



The latest approvals mean that housebuilders and drylining contractors can ensure Part E

compliance without pre-completion testing by using Knauf Gypsum Parge Coat on

separating walls of types E-WM-3 and E-WM-5 – in addition to the common E-WM-4

type approved previously. This makes Knauf Gypsum Parge Coat suitable for use in

houses, flats and all other residential buildings where masonry separating walls of these

types are specified.



Knauf Gypsum Parge Coat is used in place of traditional sand-cement renders to seal

masonry prior to finishing with Knauf plasterboards. As a gypsum product it is easy to
mix and to apply – by hand or machine – and its fast two-hour drying time is a boost for

site productivity as Knauf Wallboards can be direct bonded on the same day.



Part E of the Building Regulations requires that in new-build houses, separating walls

must provide at least 45dB reduction of airborne sound on site. Robust Details provide

conditions for constructions to comply with Part E, without pre-completion testing. With

the new approvals, builders have three options for compliance using 100mm blocks with

a 75mm cavity; each outer face is parge-coated and finished with 12.5mm Knauf

Wallboard on dabs of Knauf Bonding Compound.



Gypsum Parge Coat from Knauf Drywall is available from builders merchants in 25kg

bags – each covering 4.25m2 at a minimum thickness of 6mm. Further details on Gypsum

Parge Coat and other Knauf Drywall solutions for Part E compliance in residential

applications can be found in the Design Partner series Housing brochure, available free

from 08700 613700 or www.knaufdrywall.co.uk/literature



Knauf Drywall manufactures a full range of plasters, plasterboards, insulating laminates,

drywall accessories, metal sections and steel building systems, for domestic and

commercial applications, from factories at Sittingbourne in Kent and Immingham on

Humberside.
