PW SYSTEM (Prefabricated Wall)

PW is a structural ,composite wall panel system combining regular hardrock concrete ,approximately one inches thick on the exterior and Gypsum board on the other side ,and standard light –gauge steel framing on the inside .PW patterned structural , composite shear connector bond these two common construction element to create an engineered, load-bearing wall designed to carry floor and roof load , and Non load –bearing wall ,and to rapidly enclose the building .

Type of the PW wall panel

Class “A” EX- NLBwall : composite wall panel system combining regular hardrock concrete ,approximately one inches thick on the exterior and Gypsum board on the other side ,and standard light –gauge steel framing on the inside.

Class “B” EX- NLB wall : composite wall panel system combining Boardex sheet on the exterior and Gypsum board on the other side ,and standard light –gauge steel framing on the inside.

Class “C” EX- NLB wall : composite wall panel system combining Cement board sheet on the exterior and Gypsum board on the other side ,and standard light –gauge steel framing on the inside.

Class “D” EX- LB wall : composite wall panel system combining regular hardrock concrete ,approximately one inches thick on the exterior and Gypsum board on the other side ,and standard rectangular steel tube framing on the inside.

Class “E” EX- NLB wall : composite wall panel system combining Gypsum board on the both side ,and standard light –gauge steel framing on the inside.

Class “F” EX- NLB wall : composite wall panel system combining Gypsum board on the both outer side and bonded by MDF on the iner side ,and standard light –gauge steel framing on the inside.


Reuse External and Interior Walls

Green and 100% able to reuse and recyclable product

This kind of the wall are distinct due to Reuse .Because of panels .

A building ‘s façade in the face to the public and a protective skin on the outer wall of new or renovated building. This exterior envelope of the building creates the first impression that identifies the purpose of the building .Hence , the façade is a critical part of the building’s design statement.

The facade is the climate shield for the building .It must protect the building and occupants from environmental effect such as UV , moisture , wind , fire , noise , and temperature differences .Rock wool insulation is an ideal material that solves many of these challenges for a wide variety of external wall constructions.

With construction technology moving towards fast pace and light weight construction , dry wall exterior and partition has been widely adopted across residential , commercial , industrial and warehouse buildings. Besides the lightweight construction , panelized wall is versatile in creating interior spaces while enabling high building performances in thermal , acoustic and fire properties.

Insulation to provide performances

Typically , panels system comprises of galvanized steel stud frames lined with gypsum and concrete on each sides of the frame .However , to provide performances to the dry wall partition such as acoustic , thermal and fire properties ,non-combustible stone wool insulation is employed inside the cavity of the wall system .ThermalRock S range of stone wool insulation provides the ideal solution as it is designed to give a perfect fit within the wall frames. Dry wall partition with ThermalRock S can achieve up to STC 56 sound transmission value with varying configuration of the panels system .Due to the thermal conductivity of thermalRock range of products a 50mm thick ThermalRock S80 insulation is equivalent to 1 meter brick in terms of thermal performance.

Panel systems are very fact to erect and provide huge labour saving and flexibility in construction. Globally, panel wall system are used as replacement of brick and mortar construction.

Benefits:

1. Light weight systems- 8 to10 times lighter than conventional system like Brick /Block work.

2. Faster construction- Five to eight times faster.

3. Superior acoustics performance in times of insulation with insulation rating up to 74 dB.

4. Tested and certified system to give between1/2-4 hour fire rating.

5.Smooth finish , aesthetically beautiful crack free surfaces.

6. Flexibility in terms of modifications and refurbishment at some point in time.

7.Green and 100% able to reuse and recyclable product.

 

 

When to USE PW

Pw walls are designed for load –bearing and shear-wall conditions such as, office buildings , schools , malls hospitals , and other commercial structures . Used as a cladding panel, PW is an excellent solution to enclose pre-engineered structures or mid-rise or high –rise building with either a concrete frame or structural steel superstructures .PW wall panels , with a hard exterior concrete surface , and steel studs on the interior , afford rapid enclosure of any building type , while also supplying cavities for utilities , insulation and dry wall.

Why Use PW

PW panels are lighter than conventional precast concrete .When planning your mid-rise or high rise project utilizing steel or concrete as the structural frame you may realize substantial saving in the superstructure , footing and foundation cost , because PW can reduce the load of the exterior skin. Conventional precast panels weight 100-140 Ibs per square foot . PW panels weight 35-40 Ibs per square foot .PW panels offer the same architectural features as conventional precast .PW panels will not require the extra cost of furring the inside walls to accept interior finishes , as the lighter weight of PW panels offers the precaster the option of making larger panels to cover the same area of the building . This advantage means there are less pieces to fabricate , ship and erect .This equated to an overall saving for design builders , architects , developers and eventually the building owner.

How The Composite Wall Panel system works

PW walls are framed and cast .utilizing standard construction materials and methods.PW structural shear connectors are attached to standard light –gauge steel framing with ICBO-approved self –tapping screws. Specifically , the connector strips are fastened to the metal studs and track. These PW connectors , protruding from the framing assembly , are embedded into the wet concrete facing , creating a composite building panel of specified size and finish when the concrete is cured .PW panels can be precast or site cast ,and are installed utilizing a light –weight crane or by worker depend on size and dimention .

Building Code Compliance

PW MSC is an engineered building system . pre-approved for use under Uniform building Code requirement and ICC review have verified that full composite action is achieved by the bonding of the concrete to the metal framing assembly through the use of PW MSC shear connectors .PW MSC panels can be engineered for seismic Zone IV and hurricane –type wind load. Refer to ICC Report No ER5446 and LA. Research Reprot No 25419 for shear –flow analysis and other engineering data.
