4 Tufbloc

Tufbloc is High Density Fibremesh Reinforced (HDFR) magnesia board. The FRalso means Fire Rated as Tufbloc enjoys a very high fire-rating - upto 4 hours!

Tufbloc is an economically viable alternative and superior to existing buildingboards in the market - a technologically advanced, compact construction panelthat does what other products - traditional wood, gypsum and cement basedboards - combinedly do.

Tufbloc has a monolithic core and is the ideal building product for the mostdemanding of projects and has a positive and lasting impact on health andsafety aspects even as it extends the lifecycle of investment in a building.

ManufacturerTufbloc comes from Anutone that has almost five decades of expertise andexperience in similar products.

Right from woodwool boards introduced to India in 1966 to its many variants inthe 1990s and the invention of best-selling microfibre panels in 2000, Anutone’sEkcel division has been at the forefront of innovation in magnesium-basedproducts, refractory chemicals and inorganic bonded composites.

After the mega success of microfibre panels (MAT) in the year 2000, the designand development (D&D) team at Anutone’s Ekcel, since 2005, researchengineered for five years and now after thorough in-house testing andevaluation, has introduced Tufbloc.

Thus Anutone’s Ekcel division, which is ISO 9001 2008 and 14001 2004certified, now boasts of three major product categories:• Woodwool Boards• Microfibre Tiles• Tufbloc HDFR

StandardsTufbloc conforms to all current international building codes and standards.Extensive testing has been performed in-house at the Anutone’s BildwareResearch Facility (BRF) and also submitted to independent testing laboratories(includes CBRI, NPL, IPIRTI in India and TUV SUD overseas) for validation.

8 Tufbloc

Tufbloc is very easy to handle and install. It is easier to work with, using all typesof hand tools and wood working equipment. It can also be cut with a quick saw,and it snaps off faster than plasterboard, as it is paperless.

Tufbloc can be installed on wood and/or metal framing or directly on to steelstructure and masonry work with mechanical fasteners (screws, bolts, rivets,staples, nails) and can also be used to laminate over existing surfaces usingadhesives and cements.

Cutting - Circular saw with carbide blade

Screw fixing – self drilling screws, self countersinking; no pre-drilling necessary

Nailing – Pneumatic nails, pressure dependant on thickness and framework

Tufbloc is installed with a variety of joint fillers for different levels of functionalresistance as desired or demanded by specific applications in projects. These jointfillers are the same as used for building boards and easily available in the market.

Tufbloc is a smooth-finished lining board. It can be painted, stucco, papered ortiled to create complementary design looks. With options of taper edge for flushjointing, smooth and seamless surface is possible.

The front-side of Tufbloc is smooth to take any paint finish. The rear-side isrough, breathable and porous for strong coating and adhesive bond.

COMPARATIVE

Tufbloc is one product that suits everyapplication. It is a hard, inert board thatis integrated (homogeneous),paperless – hence there is nodelamination.

Tufbloc boasts of superiorcharacteristics over cement, gypsum,wood, pulp. Research studies provethe equivalent use of 8mm Tufblocinstead of 12.5mm gypsum or 10mmTufbloc instead of 15mm gypsum.

The ceramic-like properties makeTufbloc superior to cement board,calcium silicate boards, waterresistant drywall, gypsum board,plywood and particle board in diverseapplications. While moisture-resistant(MR or WR grade) gypsum boarddoes not absorb water as fast asnormal gypsum board, it still doesabsorb some water which results inits softening and failing.

There is a dramatic improvement inproject sites when Tufbloc is used inlieu of gypsum drywall and cementboard as it is usable for both indoorand outdoor purposes. It provides avery hard, long lasting surface that

look and feel like hard cementplastering but is fireproof and resistantto damage from water, humidity,freeze/thaw, organisms, salt and more.

As a component for light steel framing,Tufbloc allows structures to be taller,bigger and lighter, much faster thanother board products. With more optionsin thickness, for interior and exteriorapplications, it can be left natural withclear finishes or ready to receivefinishings, better than other boards byinherent superior bonding property.

Tufbloc offers a faster and betteralternative to plastering and henceused to line masonry walls andconcrete roofs. Tufbloc can be installedwith taped joints like a drywallplasterboard; or spliced using specificfillers without taping; or without anyfilling or taping to save time and moneyfor plastered tough walls at less cost. Agreat substrate to receive exterior andinterior decorative coatings directly toits surface.

Tufbloc is used for fast drywallboarding that is installed and paintedwithin hours using fast setting fillers

trimmed with a sharp blade (reducingsandpaper and sanding). Fillers canbe cut flush without a tape over thepanel joints and without needingcorner-bead, metal trims etc. whilegiving perfectly true square cornersand edges naturally. Panels can bespliced between studs withoutneeding to land joints over studs. i.e.,using strips of Tufbloc behind theseam as a back-blocking splicerstapled or screwed together results inseamless flush joints on the front.

A concrete-hard dry wall material idealfor high impact areas, hot wet andhumid areas. It receives paint directlyor as a wall tile or floor tilebackerboard. A backerboard thatprovides a strong substrate for wall tile,screwed or nailed in place without pre-drilling or laminated in layers to obtainany thickness. When nailed in placewith a light nail gun a whole room canbe made ready to tile in minutes. Everythickness from 4mm to 12mm can benailed in place to wood studs, plywoodsubfloors, particleboards ... evenTufbloc to Tufbloc with pneumaticallyapplied nails.

12 Tufbloc

GreenTufbloc is one of the most environment friendly building boards in the industry.

It is made from the world’s eighth largest resource – magnesium mineral –which makes up 2% of earth’s crust. Magnesium mineral is also the third mostplentiful material dissolved in the oceans.

Tufbloc consumes only 50% of energy to manufacture compared to cementboard and gypsum board. It is produced without wasting large amounts of fossilfuel or releasing significant CO2 into the atmosphere in production.

The entire production process is conducted at room temperature, and scraps ordrop-offs are reground and recycled in the production.

Tufbloc does not contain any organic solvents, formaldehyde, asbestos, oils,methyl alcohols or any other toxic substances that adversely impact theenvironment. Further, Tufbloc is non-hazardous, natural, non-toxic, non-radioactive and disposable as crushable clean fill in sites without contaminationor environmental damage to land, streams or bodies of water.

HealthTufbloc is termite, mildew and insect proof. It is non-nutrient and hence does notfeed mould, bacteria, fungus, rodents and other organisms as per ASTM G21.

Tufbloc has no VOCs. Hence it does not adversely affect IAQ (Indoor AirQuality).

StrengthTufbloc boasts very high impact resistance. It can be safely used at pedestrianheight in corridors. It lowers maintenance costs while ensuring higher finish.Thus it eliminates the damage due to rough tenants which is always an issue forspace owners, and helps protect assets.

Impact testing as per ASTM D5628 shows superficial crack from a drop height of150mm and hairline crack from a height of 300mm which meets the standard.

Being stronger and more rigid, it allows thinner material to do the same job andhence is not only economical but space saving – a boon in the current boom ofskyrocketing real estate prices!

BracingTufbloc boasts a high level of bracing ability. All lined areas will provide thesame brace rating when installed using the approved fixing design.

FlexibilityThe diaphragm stiffness is high which means it can be bent like thin plywood.Hence Tufbloc can be used for barrel-vaulted ceilings and other curvedsurfaces, including domes, provided the radius of curvature is narrow.

The screw-holding ability is superb and hence it eliminates the need for plybetween plasterboards which has become the norm in commercial interiorstoday to facilitate suspension of wall fixtures.

DurabilityTufbloc resists swelling, losing strength or deterioration in wet applications.It maintains dimensional stability even when wet and hence is a very durableproduct.

Only Anutone offers an unique 25-year warranty on product life, which is asupreme confidence on its longevity.

Tufbloc is made from refractory xylolith – the same material used to pyrolineblast furnaces in steel mills. Hence it has an inherent, natural ability to resist fire.It is inherently non-flammable.

Tufbloc as a product is non-combustible and as a system offers upto four hoursfire resistance. It qualifies as a Class O/A building material fulfilling all fire coderequirements across geographies.

Tufbloc is Class A1 – Non-combustible material - as per EN 13501-1 Reactionto Fire standard. It is rated Class O as per the older BS 476-4 Non-combustibility test and 476-7 Surface Spread of Flame standards.

As per ASTM

• E136 – Non-combustible

• E84 – Flame spread and smoke developed – 0

• E662 – Smoke density – NA; Non-toxic

The use of Tufbloc results in zero spread of flame and hence it is perfect forfireproofing wooden frame construction, structural steel and concrete. Used as alining material it prevents damage to the structure and hence has the ability toinfluence a reduction in insurance premiums.

FIRE

WATER

Tufbloc is water resistant more than any other building board. Accidental watercontact is no problem as it causes no swelling, melting or delamination.

Water permeability is nil with no water drops observed on the rear when water issprinkled on the front surface.

Tufbloc boasts humidity resistance of upto RH99 and hence suits tropical Asia’shot, humid climate. Can be safely used in coastal regions near the equator thatexperience harsh climates of heat, humidity and excessive rainfall.

Tufbloc does not alter its physical appearance or mechanical stabilitysignificantly after exposure to water. After evaporation or gravity flow of water,Tufbloc returns to its original state.

Tufbloc is weatherproof. It has been subjected to numerous freeze/thaw cyclesand hence is suitable for cold, temperate climes too. No change in the producthas been observed with an accelerated 25 year freeze/thaw cycle. Theprocedure is to subject Tufbloc to controlled immersion test wherein samplesare placed in closed container of water and exposed to continuous freeze thawcycles for 36 months since 2007. In 2010 the sample showed no change inphysical properties.

Tufbloc can be safely used to line the walls and ceilings of wet areas likewashrooms and kitchens.

CHEMICAL

Tufbloc is chemical-resistant. It is an inert material and can be safely used inresearch labs and chemical-intensive spaces.

Tufbloc resists the debilitating effects of salt (sodium chloride) brines and saltwater, chlorine bleach (sodium hypochlorite) and related pool chemicals andhence can be safely used in indoor swimming pools.

Tufbloc also resists ammonia (ammonium hydroxide) & related chemicals.Surface alkalinity is ~10pH.

MSDS data• Magnesia minerals• Natural silicates• Perlite• Wood flour• Water• Proprietary additives• Other trace substances

Anutone will provide detailed data on request.

THERMAL

Tufbloc is made from refractory chemicals that are used to line the blastfurnaces at steel mills. Hence it naturally resists changes in temperature upto800oC.

Tufbloc can be safely used as a refractory material for infrared radiation (heat)assisting to reduce loss of energy when heating or cooling by reducingconductivity.

LIGHT REFLECTIVITY

Tufbloc is available naturally in a off-white colour and hence reflects light.Unlike wood-based boards it does not need excessive paint to render its surfaceinto light-reflectivity.

SIESMIC

16 Tufbloc

Store Tufbloc flat on pallet trays that allow air movement. Stack each lot to amaximum height of 1m and each stack to a maximum of 3 lots or 3m. Protectfrom exposure to harmful environment.

Verify site is ready for install and all wetworks are completed. If Tufbloc isaccidentally wetted then allow to dry prior to installation. Constructionguidelines issued by central, state and local government must be observed atall times. In case of conflict with Anutone guidelines, the government guidelineswill override. Please contact Anutone for clarification.

CuttingPosition cutting station so that wind will blow dust away from user or others inworking area and allow for ample dust dissipation. Always wear protective gearincluding dust mask, goggles and earplugs. Use of gloves is recommended toprevent abrasion injuries.

Use one of the following methods based on the required cutting rate and jobsiteconditions.

Best Under score and snap using carbide-tipped scoring knife or utility knife(Ability to use this method depends on thickness being installed.)

Better Dust reducing circular saw equipped with appropriate blade and vacuumextraction.

Good (for low to moderate cutting only) Dust reducing circular saw withappropriate saw blade.

NOTES• Always use correct tools when executing cutting operations.

• Even though Tufbloc is a non-toxic building material, always wear a duskmask, safety glasses and follow MSDS Guidelines.

• Tufbloc panel ends must always be supported on metal framework. Tufblocmust not be cantilevered.

• Any surface coverings or fixtures must be supported by driving the fastenersthrough the Tufbloc onto the metal framing. Do not fasten such fixturesdirectly and independently on Tufbloc alone.

CleaningDuring clean-up, dust and debris, never dry sweep as it may excite dustparticles into the user’s breathing area. Instead, wet debris down with a fine mistto suppress dust during sweeping, or use vacuum to collect particles.

NOTES

• For maximum protection (lowest respirable dust production), Anutonerecommends always using “Best” level cutting methods where feasible.

• Never use a power saw indoors.

• Never use a circular saw blade that is inappropriate for the specific operationbeing undertaken.

• Never dry sweep - use wet suppression methods or vacuum.

• Never use a grinder or continuous rim diamond blade for cutting.

LIMITATIONS

Though Tufbloc is a strong board and impact-resistant, it is brittle andsusceptible to chipping during handling and installation. So handle carefully.

Tufbloc can only be used for non-load bearing applications. The head channelneeds deflection gap for slab movement when used in wall partitions. Maxheight of partitions is 4000 mm.

Joints between panels, whether used in walls or ceilings, must be aligned to theexpansion joint of the building.

Where exposed to continuous damp or moisture conditions, the panelsincluding edges must be sealed by primer painting or equivalent to preventwater absorption and staining.

When Tufbloc is used as a noise isolating medium care must be taken offlanking noise transmission and other issues related to acoustics. Services of aprofessional acoustical consultant is recommended.

Most of the properties are reported on the basis of laboratory tests undercontrolled conditions. The specifier/purchase must determine the suitability ofthe product to suit site conditions.

Most of the properties are claimed on the basis of complete system that mayinclude metal framing, sealants, infill etc. Use of the product with accessories byothers may render the performance and warranty void.

Tufbloc has been researched by Anutone since five years. It has beenextensively tested in-house and field trials. It is undergoing third party validationand such test reports will be available from October 2010. Being a new productfrom Anutone, its proven use, as an Anutone brand, in projects, is limited.

FREQUENTLY ASKED QUESTIONS (FAQs)

What is Tufbloc?

Tufbloc is a mineral based product that meets the criteria established to beconsidered the best for a building board or construction panel.

Why use Tufbloc?

Tufbloc is a unique product that combines the features of several products inone. It has been engineered to eliminate the toughest problems facingarchitects, engineers, contractors, builders and consumers today: Fire, Water,Sound, Insects, Fungus and Toxins.

Tufbloc is virtually impervious to fire, water and insects; is non-flammable andnon-combustible; does not feed mould or mildew; is unaffected by any insectsand termites; and is non-toxic. Literally crores of rupees or millions of dollarsget spent every year as a result of damage caused by these problems, and moreon the deaths directly resulting from these problems.

Is Tufbloc a green building product?

Yes. Tufbloc is a mineral product, completely free of toxins such as asbestos,formaldehyde or silica. It is manufactured completely at ambient temperature,and is considered a green product.

Has Tufbloc been tested?

Yes. Tufbloc has been subjected to some of the toughest tests conductedon building materials today including the freeze/thaw and 2,000 hourweathering test which is a 20 year accelerated weathering test. It thus farexceeds ASTM requirements. All testing has been done in-house asrequired by AC386 issued by the International Code Council (ICC) and inaccordance with ASTM requirements. Anutone is ISO certified and isaudited periodically to ensure consistent quality in every order. Externalvalidation is under progress.

Is Tufbloc dimensionally stable in freeze, thaw, heat and humidity cycles?

Yes it is. Unlike cement type materials, the coefficient of expansion for Tufblocis extremely low; therefore, when selecting and installing products such as ourexterior lap siding, there is no need to leave gaps between butt joints toaccommodate for such expansion and contraction. This provides a much moreaesthetically pleasing finish for many years to come.

What are the adhesion values of Tufbloc?

Excellent. Allows you to finish with any product you desire such as paint, cementstucco, synthetic stucco, wallpaper, stone, tile, brick, metal as in ACP and muchmore. The excellent adhesion properties of Tufbloc also make it a perfectproduct for Structural Insulated Panels (SIPS), Exterior Insulated Finish Systems(EIFS) and interior wall systems using fabric cladding.

Is Tufbloc cost competitive with other products?

Yes, considering overall installation and lifecycle costs. By using Tufblocyou don’t have to worry about such things as insect damage caused bytermites, ants and other such pests; decay caused by moisture and UV;warping, swelling and rot caused by water; mould and mildew; and, toxinsthat are found in many wood, plastics, gypsum and cement basedproducts. Much thinner panels achieve much higher saving youexpensive space costs.

23Tufbloc

Can I order non-standard sizes?

Yes. But Minimum Order Quantity (MOQ) applies.

How do I store Tufbloc?

Storage and handling of Tufbloc is easy. It does not require the same attentionas wood or gypsum type products do. Tufbloc can actually be submerged inwater for months with virtually no dimensional change whatsoever; and, itleaches water quickly, never feeding fungus or mildew or suffering decay orwarping as do most wood and gypsum products. And since Tufbloc is ahomogenous product, there is no delamination ever.

Is Tufbloc easy to install?

Yes. Tufbloc installs with mechanical fasteners - screws or pneumatic nailers -depending on the application. Always follow the Anutone installationrecommendations. Finishing interior walls and ceilings is also easy using standard jointcompound and glassfibre joint tape. Since Tufbloc is smooth on one side, you canachieve a level 5 trim with much less work (man-hours) than typical gypsum board.

When installing Tufbloc as underlayment or backer board there are no changesin preparation for installation from processes being used today when installingother materials; however, use only thin set materials and not mastics.

Is Tufbloc safe for installers?

Yes. In fact installing Tufbloc is as safe if not safer than installing any othermaterial in the market today. Tufbloc is a mineral-based product free ofcarcinogens and silica. It has been tested and found to be non-toxic. So, Tufblocis extremely safe for installers and consumers alike. You may obtain a copy ofour Material Safety Data Sheets (MSDS).

How can Tufbloc be finished?

Tufbloc can be finished with just about anything in the market today includingpaint, cement stuccos, synthetic stuccos, wallpaper, plaster, brick and stone andmuch more. As with most products, manufacturers of these products will guideand in some cases their authorised applicators will perform the installation.
