"India's only high-pressure steam cured fibre cement board"
FLEX-O-BOARD is an improved version of fibre cement flat sheets, developed after years of systematic product research and a better understanding
of consumer needs.
FLEX-O-BOARD is the only fibre cement board in India which is cured by the high-pressure steam-curing process known as 'auto-claving'. Thanks to the
physical properties of its constituents and the exclusive process of autoclaving, FLEX-O-BOARD retains all the advantages of conventional water-cured fibre cement flat
sheets and, in addition, offers certain special features.
Tough, flexible and durable, FLEX-O-BOARD combines economy with utility. It proves an ideal material for architects and interior decorators, and
enables execution of imaginative designs. It provides ample scope for both functional and decorative forms, incorporating ideas with colour schemes.
SPECIAL FEATURES
Smoother, Whiter Surface FLEX-O-BOARD is smoother and whiter than conventional fibre cement flat sheets. The smooth surface blends well with any surrounding, as such there is no need for surface
applications. However, if added decor is desired. FLEX-O-BOARD can take in any paint, any shade.
Greater Dimensional Stability
The steam-curing process and special constituents of FLEX-O-BOARD make it crystalline, whereas conventional fibre cement flat sheets are amorphous. This gives
FLEX-O-BOARD greater dimensional stability and makes it warp-free.
Better Paint Retainability
Normal water-cured fibre cement flat sheets contain about 11% free lime. This causes a 'leaching' action, which tends to eat away surface applications. On the contrary,
FLEX-O-BOARD has negligible free lime content, which makes it easily paintable and gives it better paint retaining properties.
The special features make FLEX-O-BOARD tough, durable and flexible. Toughness allows storing and handling outdoors without unusual precautions. Durability ensures lifelong
dependability and economy. Flexibility provides a wider scope of design opportunities.
The Versatile Product FLEX-O-BOARD is ideal for use in both interiors and exteriors of modern constructions, commercial, industrial and residential buildings. It is an easy-to-fix material for
false ceilings and partitioning, wall-lining and panelling.
Fire Resistance FLEX-O-BOARD is non-combustible. Subject to fire hazard test, FLEX-O-BOARD has the following early fire hazard indices.
WARP-Resistance
Being crystalline, FLEX-O-BOARD is not affected by the vagaries of temperature fluctuations and can withstand extremes of both heat and cold. It is, therefore, ideal for
use in cold storages and humidification plants. It is immune to moisture, corrosion, vermin and weather.
FLEX-O-BOARD does not transmit heat or electricity readily and proves an ideal building board especially in high temperature zones.
STANDARDS
The relevant specification for strength and other properties is IS:13000-1990. Silica Asbestos Cement Flat Sheets.
SOME MAJOR APPLICATIONS OF FLEX-O-BOARD
• False-ceilings for offices, factories, textile mills, MES barracks, auditoriums.
• Partitions in offices, workshops,-factories, farm buildings, schools.
• Blackboards in schools, colleges, demonstration units.
• Signboards for dealer shops, outdoor display.
• Background for neon lights and other artificial lighting devices.
• Outdoor hoarding, wall panelling, cladding, curtain wall, etc. especially in warm coastal areas where wood rots in the presence of moisture.
Miscellaneous furniture like pantry and kitchen shelves and back of wardrobes.
• Return air-boxing and enclosures for air-conditioning ducts.
• Cold storages. Side louvres for cooling towers.
• Table tops for textile printing.
• Sandwich Panels.
• Backing material with or without lamination/veneer/surface textures.
CHARMINAR Newkor Roofing Sheets are made from an intimate mixture of Fibre, Portland Cement and binder. Fibre in these sheets acts as reinforcement in the same way
as steel in RCC.
CHARMINAR Newkor sheets are manufactured to exceed the requirements of strength specified in the relevant Indian standards.
STANDARDS
IS:459-1992 Specification for Corrugated and Semi-Corrugated Asbestos Cement Sheets.
IS: 3007-1999 Code of Practice for laying of Asbestos Cement Sheets, Part-1, corrugated Sheets, Part-2, Semi-Corrugated Sheets, IS-1626(P3) 1994 - Roofing Fittings
Newkor Sheets are economical, non-combustible, robust, light-weight, easy to work, resistant to corrosion and salty weather... the qualities which make them an ideal building
material for any requirement.
Newkor Sheets have good thermal insulation properties and do not produce drumming sound during rain or hail storm.
Newkor Sheets are most suitable for roofing and vertical cladding (walling) of industrial and agricultural buildings, warehouses, sheds, poultry farms, houses, etc.
OTHER APPLICATIONS
Charminar Roofing Sheets are an ideal building material for roofing and side-cladding in :
• Industrial Buildings of all types
• Food Storage Godowns
• Warehouses & Cold Storage Godowns
• Poultry Farms, Dairy Farms and other Agricultural Sheds
• Houses
• Garages, Verandahs and Outhouses
• School Buildings
• Public Utility Sheds
• Cooling Towers
• In coastal and hilly areas for Industrial Buildings, Houses, etc.
• Cinema Halls
• Stadia
• Railway & Bus Stations
IMPORTANT POINTS
1. Don't stack more than 120 sheets in a stack
2. Smooth surface of the sheet should be upwards
3. Never punch holes - drill them
4. Drill holes in sheets - at least 3 mm larger than fixing bolts
5. Be sure, sheets are mitred by cutting with a saw
6. Be sure, sheets are mitred correctly
7. Nuts should be screwed lightly first and tightened only after 13 or 14 sheets are laid
8. Tighten the nuts evenly allowing the bitumen washer to merely seal the space between the holes and the bolts
9. Don't overtighten the nuts. Allow for the movement of structure
10. Don't exceed purlin spacing of 1.4 metres for roofing & 1.7 metres for side claddings
11. Provide a purlin at every end lap
12. Don't exceed free overhang of 300mm at eaves
13. Distance between outlets in gutter line should not exceed 15 metres
