INSULATING SCREED OF CORK AND LIME
Premixed for screed containing our own granular blond cork, NHL5 natural hydraulic lime and wheat straw; minor components are cellulose and additive for the machine workability of the dough. With Bioart-Thermal cork screed, a load-bearing insulating screed is made with a high thermal and acoustic insulation value.
ADVANTAGES OF CORK THERMAL SCREED
High insulating value thanks to the presence of only high quality granular cork, as an inert mixture. - High soundproofing value, even for trampling noise. - Breathable and healthy because it is composed of natural cork, vegetable straw and natural hydraulic lime to form a highly macroporous mixture. - Suitable for direct paving: for the bearing capacity of the screed and for the relative regularity that the surface can take. - Ideal for those situations of subfloors with the presence of plants to be covered and little overall space: with the cork thermal insulating screed, the systems are covered and the thermal insulation is achieved with a single intervention.
TECHNICAL CHARACTERISTICS
cork insulator Maximum aggregate diameter: 5 mm Dry density: ~ 500 kg / mc Workability time: approximately 60 minutes Application temperatures: from + 5 ° to + 35 ° Yield: About 5 kg / m2 per centimeter of thickness (for thicknesses from 5 to 12cm) Appearance: hazel color Thermal conductivity (lambda): 0.093 W / mK Conf: bag of 33 LT (1/30 of mc) of around 17,5 kg.
RECOMMENDED USE
1-Thermal underlay formation suitable for tiling.
2-Thermal underlay formation for glued parquet.
3-Formation of lightened substrate for parquet nailed on Chestnut.
INSTALLATION
The surface to be covered must be dry and clean. Mix the product with clean water (approximately 14 L) until a homogeneous, lump-free mixture is reached. For manual applications, mix the mixture in a cement mixer for about 3 minutes. The mixed mortar should be used within a maximum of 60 minutes. The product must always be applied using the reference bands for the thickness of the screed itself, stinging and compacting it to then float to obtain a good flatness. The minimum achievable thickness is 5 cm. Over 10 cm it is advisable to throw the product in two coats of equal thickness. The complete maturing of the screed that gives maximum resistance to compression is achieved in 28 days, in very hot and windy periods it is recommended to protect the screed from drying too quickly, avoiding direct sunlight and ventilation of the premises.
1- FOR TILING
After the curing of the insulating screed and never before 15 days from casting, it is advisable to lay a leveling layer in a thin layer max 5 / 7mm of the T-level Tassullo type for greater regularity of the surface and to increase the compressive strength of the substrate. Item specifications Formation of cork and hydraulic lime thermal insulating foundation of the Bioart-Masetto thermal type of cork Artimestieri. Preparation of the laying surface by spreading a T-level Tassullo type leveler, in a thin layer of 5 / 7mm.
2- FOR LAYING THE GLUED PARQUET
After the 28 days of complete curing of the insulating screed, carry out the first measurement of the residual humidity, when this is within the tolerances proceed with the laying of the T-level Tassullo leveler. After the final check of the residual humidity proceed with laying the parquet. Item specifications Formation of thermal insulating load-bearing screed of cork and hydraulic lime of the Artartestieri type Bioart-Masetto thermal cork. Preparation of the laying surface by spreading a T-level Tassullo type leveler, in a thin layer of 5 / 7mm.
3- FOR LAYING THE NAILED PARQUET
Bioart-cork thermal screed can be cast among the Chestnut slats previously prepared for nailing the parquet. After 28 days, measure the residual humidity: the drying times vary according to the seasonal temperatures and the thicknesses achieved. Lay the parquet only when the lightened substrate is completely dry. Item specifications Arrangement of a thermal substrate suitable for nailing the parquet by placing chestnut slats and then throwing a cork thermal screed in the interstices with the Bioart-riveting system on Artimestieri thermal screed.
