Improvingtheinsulationefficiencyofbuildings,whetherneworrefurbished,isamajorissueinthereductionofgreenhousegas emissions. Today, insulating your home should be anecological reflex action, beyond energy-saving concernsandmattersofcomfort.Indeed,theprotectionofourplanetrevolvesaroundtwomajor issues: thefightagainstclimatechangeandthereductionofour"fossil"resourceconsumption(oil,gas,minerals,etc.).

Reducing heating consumption by improving insulation isthereforeafirstecologicalaction.Choosinga"bio-sourced"insulation,which is efficientandnatural,made fromhempfibres,providesanadditional,specificresponsetoecologicalconcerns.

This is the gamblewearemakingwith theBiofib’rangeof"Eco-logical"insulationsystems!By controlling the entire production chain (growing hemp,defiberingandburling,packaginganddelivery to the site),Cavac Biomatériaux claims to be unique in combiningtechnicalefficiencywithsettinganecologicalexample:•A"hemp"cropthatisrenownedforitsecologicalvirtues.•A complete production chain: hemp and flax are grownbythefarmersinourcooperativeandprocessedinVendée(defiberingandburlingonthesamesite).

•Low embodied energy needs: observance of a true "shortcircuit"with cropsnear the industrial site, resulting in lesstransportationandaclearlypositivecarbonbalance!

•The quality of an industrial production that meets theexpectations of our partners and customers (quality,consistency,volume,traceability,prices,etc.).

Thesearea fewof thearguments thatback thepromiseofourBiofib’range:efficient, truly durable insulation!

Really ecological solution for floor levelling

Biofib’ pellets (Biofib’ chape) pellet-based insulation boards are made of fine particles of plant matter derived from the separation of hemp and flax fibres which are then compacted in a high-pressure process without binder. A natural insulator, Biofib’ pellets is specially recommended for underfloor renovation work and for levelling floors that are irregular or in poor condition.

Specific qualities of Jetfib’ouate

Jetfib’ouate is a thermal and acoustic insulation made of cellulose wadding from recycled newspapers.It is applied by pouring, blowing, injection or projection. Jetfib’ouate is particularly recommended for insulating inaccessible, cold attic spaces.Its quick and efficient application means savings are made both in time and money.

RECYCLING FOR ECOLOGY

Cellulose wadding is an ecologicaland recyclable material made fromcarefully sorted recyclednewspapersorcutsofnewpaperfromtheprintingindustry.

In addition to its ecologicaladvantages, cellulose waddingprovidesexcellentthermalandphonicinsulation. Micro-organism resistantand rot-proof, it is open to watervapourdiffusion.

All these qualitiesmean that cellulosewadding is one of the best insulationmaterials in terms of ecological andtechnicalvalueformoney.

Compared with synthetic materials,cellulose wadding insulation requiresvery little energy for production andthushelpstoprotecttheenvironment.

Use of cellulose wadding thereforefully complieswith low environmentalimpact sustainable development byreducinggreenhousegasemissions.

Air-tightness & performance

The thermal and acoustic performance

of a building are closely interrelated

with the tightness of the insulated walls,

which depends on the Biofib’ control vapour

barrier, while allowing the materials to breathe

naturally.

Biofib' knife

The Biofib’ range of construction tapes is specially designed to cover all your needs when installing the Biofib’ control vapour barrier. Each tape is suited to a specific application: yellow tape for covering the strips, green tape for sticking the vapour barrier to all types of supports, brown "double-sided" tape for attaching Biofib’ control to the framework (timber or metal).

For quick and clean cutting of the batts and rolls of natural insulation products, use the Biofib’ knife (length 30 cm), which is supplied with its own sharpener. For working areas that require a large number of cuts, you can also use a disk knife equipped with a toothless disk (ø 115 to 230 mm).

The Biofib’ control vapour barrier is a technical film made up of a non-woven fabric and a polypropylene membrane. Impervious to air and water, it prevents seepage and therefore reduces the risks of condensation forming inside the insulation (temperature < dew-point). Although not completely sealed against the vapour barrier (pervious in both directions), Biofib’ control plays an important role in natural moisture control in your home. It provides the perfect complement for Biofib’ insulation products.

Why choose natural insulation products ? The active communication with the general public conducted by the ADEME highlights major issues relating to general energy savings, specifically in construction. In fact, the energy consumed in dwellings (residential and services) represents 43 % of total consumption, ahead of transport. Even more important than the collective efficiency of insulation is the choice of insulation.

Cavac Biomatériaux exclusive: a complete "Eco-logical" system

In terms of natural insulation, Cavac Biomatériaux clearly stands out from the competition, relying on a true complete production system "from the field to the construction site". In fact, as part of the Cavac farming cooperative group, it manages all the hemp cultivation stages performed by the farmers in its territory so as to ensure industrial-quality production of Biofib’ insulation systems (defibering of straw and burling, packaging and delivery to construction sites).

The Biofib’ range of insulation systems claims to haveexemplary behaviour in ecological termsnotonlydue totheefficiencyofitsthermalinsulationmaterial,whichnaturallyresultsinenergysavings,butalsoduetotherawmaterialsituses,which are renewable and plant-based ("carbon sinks")and its "shortcircuit"productionmode (less transportation),producingaclearly positive carbon balance.

This is known as "built-in" insulation since the Biofib’ batts are placed between the wooden uprights in one (or two) layer(s).

When placing a double layer with "staggered joints", it is necessary to place, perpendicular to the supporting uprights, a row of cleats, with their depth depending on the thickness of the second layer of insulation.

Injection is used to insulate walls, partitions or intermediate floors. The walls to be insulated are made up of closed cavities that will keep the insulation in place. They are pierced at the top, in the centre of each cavity, to enable the injection pipe to pass through. Filling is performed from bottom to top while observing the density.Jetfib’ouate is packaged in 10 kg bags (40 bags per pallet): 2 pallets are required to insulate with approx. 180 mm thickness over 100 m2 (corresponding to a R>4).

Blowing is used to insulate cold or inaccessible attic spaces (e.g.: prefabricated roof structure made of industrial trusses). Insulation application involves blowing Jetfib’ cellulose wadding on the floor or suspended ceiling between the tie-beams.Jetfib’ouate is packaged in 10 kg bags (40 bags per pallet): 2 pallets are required to insulate with 240 mm thickness over 100 m2 (corresponding to R>5).

roofInsulation unrolled on the floor

The roof space, which consists of a conventional framework, is ventilated, unfinished and unheated. Installation will simply consist of unrolling the insulation on the floor or between joists and completing the insulation with a second layer staggered perpendicularly if necessary.

Tip:In the event of installation with staggered

joints, in order to avoid walking on and

damaging the first layer of insulation, use a

barge board on which you can walk.

floors & CEilinGs

An intermediate floor, with a light structure made up of wooden joists, separates two volumes, at least one of which is heated. The insulation will consist of filling the spaces between joists with semi-rigid insulation (rolls or batts) or manually deposited fibres.

Tip:To complete the insulation against impact noise,

an acoustic layer made from flax or PE foam with

a thickness of 3-4 mm may be added once the

insulation has been made and before installing the

final floor.

The light building walls are made up mainly of a metal framework, covered with a facing (wood, gypsum, Fermacell, etc.) on either side. Distributive partitions (used for distributing the rooms within the same dwelling) are differentiated from separating partitions (for separating two dwellings). The difference between the two is found in the associated thermal and acoustic requirements.

Tip:

For optimum efficiency, in particular as regards

the acoustics of the partition, it is advisable:

• To add a resilient sole under the rails, on

the floor and the ceiling (reducing the

transmission of solid-borne noise – vibration)

• To place electrical cases (sockets or switches) in

staggered rows.

• To place a double facing on one of the sides

of the partition and to use Fermacell batts.

In the case of a single framework •PleaseconsultpointNb.6:Interior.

In the case of a double framework (dwelling separating partition)

•Placeasecondmetalframeworkatadistanceof40to60mmfromthepreviousone(consultpoint1).
