Design Table for maximum wall height without horizontal bracing.
These table is just for reference, many more combinations are possible considering height and spacing.
Fire Resistance
Pared Frame provides minimum 2 hours of fire rating due to certain unique properties like:
- Paustic board itself is a fire resistant.
- Pared Frame uses 10mm thick Paustic board as its sheathing material on each side.
- 100mm thick Rockwool is placed in the cavity, which is non-combustible and possess superior insulating properties which helps in retaining the fire to a great extent.
- Studs are non-combustible.

Acoustics
‘Sound not desired by the recipient’ can be defined as Noise. It’s source of origin could mainly be from two places outdoor and indoor.
Typical sound levels (in dB)
- Outdoor noise mainly consists of road traffic, railways, aero planes, loudspeakers etc.
- Indoor noise is generally generated due to conversation between occupants, footsteps, banging of doors, playing of radio and T.V, ringing of phones, flush tanks etc. which generate noise levels up to 70db. We are always more concerned about the indoor noise levels.
Paustic boards and insulating material which are parts of the Pared Frame system are the key elements which help to reduce noise level significantly. Pared Frame
system can achieve noise reduction of up to 54db.

Sound transmission
Every wall is a flank wall when it comes to sound transmission in a closed area.
As and when sound is generated in a closed place it directly faces the adjacent walls.
Flanking sound (or flanking noise) is sound that transmits between spaces indirectly, going over or around, rather than directly through the main separating element. This can allow sound to transmit between spaces even though the main separating element itself provides good acoustic insulation
1. Sound passing through wall
Direct transmission occurs when the sound generated inside the room is more than it tends to transmit through the wall.
2. Sound passing from adjoining structure
Not just the walls but it also gets transmitted through the adjacent structures.
3. Sound passing through floor, ceiling voids, ducts, etc.
Sound also tends to transmit through the floor and other ducts conduct provided in the system. As people travel on the floor it tends to generate the sound and it will definitely transmit some amount to adjacent place.
4. Sound passing through gaps in doors, windows and ventilations
When any sound is generated in a closed room it definitely travels through the opening and the gaps available in the openings of door, window, ventilation, duct etc.
