PuraSoundAcoustic Rated Doorsets
Whilst all doors will offer a level of sound attenuation, there is increasing awareness and compliancy requirements to achieve in the construction of doorsets and screens to restrict the passage of sound. Dorplan’s PuraSound timber doorsets can be supplied with a variety of door cores, seals and glazing types to achieve dB ratings up to 43dB.
Acoustic perimeter seals are often combined with intumescent strips where on fire doors but surface fit options are available. Automatic drop seals are installed into the bottom of such doors and concealed form view. When the door closes into the frame, a projecting lug in the jamb is pushed in by the frame and a neoprene seal drops to cover the gaps between the door and the finished floor. This also is beneficial for draughts, light penetration and odour barriers.

The benefits that having doors pre-hung in frames with relevant hardware morticing works carried out in the factory is increasingly seen as the obvious solution to the demands on contractors. This reduces the labour force required on site, the level of skill required to install, the management resources required to oversee and the installation time required on site. This all helps in projects where programmes are tight and excellence of carpentry works is borne by CNC machinery in the factory which take the onus of responsibility from site level to production level.
