WALL SYSTEMS

Wall systems for interior works are non-
load bearing constructions that enclose
the space.
Typology:
1.Masonry
2.Reinforced concrete
3.Stud walls
4.Glass partitions
5.Demountable partitions
Heavy-weight
Light-weight

Requirements:
1.Space dividing
2.Integration of technical systems: heating,
cooling, electrical …
3.Architectural & aesthetic
4.Fire resistance,
5.Thermal insulation
6.Sound insulation
7.Acoustic requirements
8.Load-bearing, structural requirements of
heavy equipment
9.Substrate for specific finishes

Selection criteria for wall
construction:
1.Thickness of the wall
2.Height of the wall
3.Weight of the wall
4.Flexibility & demountability
5.Integration of technical services
6.Integration of windows, doors, openings
7.Site operation aspects

Architectural requirements:
1.Shape: straight, irregular, curved,
coves and niches
2.Integrated lighting (cove lighting)
3.Minimum footprint, slender
partition with adequate sound
insulation and fire resistance
4.High moisture loads
5.Enhanced structural
requirements: TV screens, shelving,
hang furniture, paintings etc

Shape:
Straight
Irregular
Curved
Coves & niches

Design principles
1.Non load-bearing walls:
lightweight partitions, flexible, drywalls
2.Stud wall systems and walls:
made from preformed parts (wooden)
assembled on site
3.Demountable partitions and
glass partitions: prefabricated
elements or segments, erected and
joint together on site

Aplications:
• standard construction (partition)
• fire rated boundary walls
• multi-residential dividing walls
• acoustic walls and ceilings
• home cinemas
• curved walls
• wet area walls
• Impact wall and hardness needs

Stud wall systems and walls
System:
• Supporting frame metal of timber
sections
• Cladding with board materials to
form interconnected whole
• Filling insulating (thermal, sound,
fire) materials and space for routing
pipes

Stud wall systems and walls -
metal

timber

Stud wall systems and walls
Wall thickness: 75 – 150 mm
Wall grid: 125 mm
Wall height: up to 12 m
Sound insulation and fire
protection
Cladding and enclosure: wooden
boards, Cement-bonded boards, OSB

Criteria for choosing board
material:
1.Mechanical properties and strength
of drywall structure in whole and
surface (compressive and impact
strength, TV installation, sound systems
etc)
2.Building physics properties (fire
protection, sensitivity to moisture, vapor
permeability, extension behavior)
3.Surface finish and materials, type of
cleaning, application of finishes
(painting, plastering, wallpapering etc)
4.Design requirements (shaping,

installations:

Potentially soundproof critical
moments
1.Built-in items such as power sockets,
inspection openings, luminaries
2.Door, high level windows, glazing,
openings
3.Weak points of junctions and
transitions, skirting boards, floor level
etc)

Criteria for choosing floor system
1.Appearance
2.Geometry
3.Surface characteristics
4.Load-carrying capacity
5.Acoustic properties
6.Fire protection properties

10.Type and properties of structural
floor

Floor systems typology
1.Dry floor : dry subfloor layers, impact
sound insulation, dry flooring materials,
suitable for refurbishment and offices)
2.Hollow floors : screed floor and seamless
surface with void bellow, space for technical
services
3.Raised access floors : flexible flooring
systems made from panels supported above
structural floor n pedestals, 60 x 60 cm grid.
Void for technical services, suitable for offices
with high service density

1. Structural floor
2. Multitherm floor
heating pipes
3. Heat-conducting
4. Dry screed slabs
5. Tiling
6. Wood
7. Carpet

Dry floor

1.Resilient floor: PVC, linoleum
2.Textile: carpeting
3.Hard floor covering: ceramic tiles, wood
laminated, wood block flooring
Floor coverings for dry subfloors

- A raised floor (also raised flooring) or
access floor(ing) are types of floor that provide an
elevated structural floor above a solid substrate (often a
concrete slab) to create a hidden void for the passage
of mechanical and electrical services.
- Consists of a gridded metal framework or
substructure of adjustable-height supports (called
"pedestals") that provide support for removable
floor panels, which are usually 60×60 cm in size.
- The height of the legs/pedestals is dictated by the
volume of cables and other services provided beneath,
but typically arranged for a clearance of at least six
inches or 15 cm.
Access floor

• The panels are normally made of steel-clad
particle-board or a steel panel with a
cementitious internal core.
• Each panel is supported by four corners on
height-adjustable pedestals which are fixed
to structural floor.
• In the void are installed sound insulation and
technical services
• Panels may be covered with a variety of flooring
finishes to suit the application such as carpet
tiles, high-pressure laminates, marble,
stone, and antistatic finishes.
