EDILANA MAT3

EdilanaNeedle-felt mat in pure virgin wool from indigenous sheep of Sardinia for its thermal-acoustic insulation and hygrometric wellbeing.

Description of the product

MAT 3 Edilana is a needle-felt mat in pure virgin wool from indigenous sheep of Sardinia with its thermal insulation, sound-insulation and hygrometric regulation of the environment. It is recommended for ventilated and non-ventilated roofs, exterior walls, interior walls, floors, false ceilings, for the insulating and the filling of window and door frame airspaces. MAT 3 has mothproof protection, has no anti-combustion additives, no allergens, to be laid without dustproof coat. It is particularly simple to lay. The MAT 3 mat has a thickness of 3 cm and is supplied in rolls of 10 ml, 0.60 mt wide and upon request can have widths up to 2 mt.

Features of MAT 3

The wool of the MAT 3 Edilana product is obtained from white and black sheep raised in Sardinia that live in the wild in semi-uncultivated fields, spread from the sea to the mountains. The mixture of white hair and black hair strengthens the quality of the product.

EdilanaThermal Insulation

Thermal insulation is provided by the amount of air that a material manages to trap: the scales of the Sardinian sheep’s wool give the fibre a certain coarseness and with their interstices increase its surface. Its insulating power remains constant even when there is humidity. The Giordano Institute has certified a thermal conductivity of 0,0339 W/mkm standard UNI EN 12667:2002.

EDILANA Soundproof Power

Edilana Mat 3 has excellent acoustic insulation power capable of creating an effective barrier to sound. The fibre of the wool (the Sardinian one in particular) has a very rich sinuous hook, with strong spiral shape that not only permits the reduction of auditory pollution but of acting on the structure of the sound improving it. The Giordano Institute (Standard UNI EN ISO 140-3-2006 and UNI EN ISO 717-1:2007) has certified a reduction of 54 dB by inserting a single layer of Mat 3 between two bricks of 8 and 12 cm respectively with exterior plaster.

Hygrometric Control of the Environment

Sheep’s wool is the most hygroscopic fibre that exists in nature. That is, it is capable of absorbing water vapour up to a third of its weight without appearing wet, without swelling or changing its structure. At the same time it is capable of slowly releasing the water absorbed regulating the humidity in the environment. The waxy material (lanolin) that coats the fibres made the wool water-repellent. The excellent control of the humidity, with development of heat during the absorption phase avoids phenomena of condensation. With humidity, some waterproof insulating materials block perspiration causing unhealthy phenomena of condensation and development of
moulds. Other transpiring insulating products instead replace the trapping of the air with that of the water, thus losing insulating capacity. In fact, it is the presence of water in the material that transmits towards the inner part the outside temperature. The excellent insulation-transpiration properties of the Edilana product is due to the ratio between lambda(0,0339) and the coefficient of resistance to the diffusion of the water vapour: value µ equal to 2,3 certified by the Giordano Institute (standard UNI EN 12086 – 1999).

EdilanaResistance to Moulds and Bactericidal Power

The fibres of sheep’s wool (lactiferous) thanks to the strong protein structure, are not only resistant to moulds but actually fight their development. The mothproof treatment which it is put through is non-toxic and its efficacy has been certified by the Giordano Institute Standard ISO 3998:1977. The Sardinian sheep’s wool of the Edilana mat maintains intact its natural features over time. It is bactericidal and thanks to its scarce static electricity it does not attract nor accumulate dust, is non-toxic, devoid of glue, resins, polystyrenes, can be recycled, does not rot, is biocompatible, does not irritate the skin, and does not produce breathable fibres or those that can be inhaled.

Fire-Retardant Capacity

Sheep’s wool has a high fire-retardant power: it catches fire with difficulty, is self-extinguishing, does not melt, does not drip, chars quickly and does not spread flames, produces little heat and little smoke. The wool fibres suffer damage at temperatures greater than 250°C and combustion occurs at a temperature of 660°C.

Installation

The fastening can be done by using various plugs with wide washer, used also for insulating panels of other types, by making on the brick wall a hole with a 10 awl and putting the plug in directly. In the case of brick without plaster a nail with washer can be inserted between one perforation and the other. It is no advisable to pierce the wool by using a drill since it resists the rotation wrapping around itself. We do not recommend the use of any type of adhesive. Always use mechanical fasteners.
The EDILANA Mat 3 has two sides: one side smoother and more uniform and one side coarser and shaggy. This feature is a strong point of the product since it permits greater ease of installation especially on rough surfaces, a better bond in the overlapping of several mats and consequently a reduction of the thermal bridges. The installation of the mat on a support must be done with the coarser side turned towards the support (see figure).
The roll is supplied with the coarse side out.
We recommend storing in covered warehouses.
