THE MEDITERRANEAN BLEND OF COMFORT IN DIATHONITE SCREED, CORK PLAYS AN ESSENTIAL ROLE IN THE PERFORMANCE OF THERMAL AND ACOUSTIC INSULATION . ITS UNIQUE PROPERTIES LIGHTNESS, MECHANICAL STRENGTH AND POROSITYARE WHAT UNDERPIN THE EXCELLENCE OF DIATHONITE SCREED Cork has always been the trademark and distinguishing feature of the Diathonite line. Our Screed is no exception, offering outstanding protective and insulating properties. Cork limits heat loss, by improving thermal comfort when used in a product that serves as a screed. Thanks to its natural resilience it guarantees acoustic...

THE DIATHONITE SCREED FORMULATION COMBINES ALL THAT NATURE HAS TO OFFER IN ORDER TO PRODUCE A MATERIAL WITH THERMAL AND ACOUSTIC INSULATION PROPERTIES COUPLED WITH MINIMUM THICKNESSES AND A LOW ENVIRONMENTAL IMPACT. NHL5 HYDRAULIC LIME: THE AGE-OLD WISDOM DIATOMACEOUS EARTH: TREASURE FROM THE OCEANS OF MEDITERRANEAN BUILDING All the raw materials used in the formula are of natural origin, allowing the product to meet the most stringent requirements of environmental and ecofriendly certification. Produced by heating (calcining) limestone that naturally contains clay and other impurities, it...

DIATHONITE SCREED: THE ECO-FRIENDLY MULTI-PURPOSE MORTAR DIATHONITE SCREED OFFERS A SMART, INNOVATIVE RESPONSE TO A TWO-FOLD NEED: TO IMPROVE THE THERMAL AND ACOUSTIC COMFORT OF LIVING SPACES. THE MATERIAL'S THERMAL CONDUCTIVITY VALUE CHARACTERISES DIATHONITE SCREED AS A MORTAR WITH EXCELLENT THERMAL PERFORMANCE WHICH GREATLY OUTPERFORMS TRADITIONAL SCREED SOLUTIONS. Diathonite Screed is a mortar providing strength that makes the surface walkable, meaning it can be applied as a finish screed, even with minimum thicknesses and without overloading the floor. Thanks to the natural materials...

DIATHONITE SCREED: APPLICATION FIELDS FOOTFALL SOUND INSULATION FOOTFALL SOUND TRANSMISSION IS CAUSED BY VIBRATIONS THAT PASS THROUGH THE SLAB, TRANSMITTING THE SOUND TO ROOMS BELOW. TO ELIMINATE FOOTFALL SOUND, A MAT IS LAID BETWEEN THE SLAB AND THE SCREED: MADE OF RESILIENT MATERIAL, THE MAT SEPARATES THE LOADBEARING STRUCTURE FROM THE FLOOR, PREVENTING THE TRANSMISSION OF VIBRATIONS. Diafon is a soundproofing mat which is used in conjunction with Diathonite Screed to effectively insulate against the sound of footfall by creating a “floating floor”. Slabs on grade Slabs above unheated...

THE NUMBERS BEHIND COMFORT INSULATING, THERMAL AND ACOUSTIC PROPERTIES THERMAL CONDUCTIVITY λ = 0.060 W/mK Thanks to the right mix of carefully selected natural raw materials, the product achieves impressive levels of acoustic insulation. ACOUSTIC INSULATION ∆Lw = 22 dB L’nw = 58 dB Cork and its porous structure allow the achievement of excellent levels of footfall sound insulation. REACTION TO FIRE CLASS A1 Classified as class A1 according to European standard EN ISO 13501-1. No production of flaming and no emission of smoke.

STRUCTURAL VALUES MECHANICAL PROPERTIES FLEXURAL STRENGTH The aggregates contained in the matrix make the product extremely light, facilitating applicability. COMPRESSIVE STRENGTH Given the presence of natural hydraulic binders, the product is classified as class CS5 that is declared to be a suitable mechanical strength for finish screeds, in accordance with the CE marking and EN 13813. Highly flexible, the product can be applied to supports or slabs which may produce movement.

PERFORMANCE WITH SUSTAINABILITY Diathonite Screed performances are guaranteed by the product certification, issued by certified bodies, which are universally renowned for their reliability and rigour. DIATHONITE SCREED HAS OBTAINED IMPORTANT ENVIRONMENTAL AND PERFORMANCE CERTIFICATIONS THAT ANALYTICALLY VALIDATE BOTH THE PRODUCTION PROCESS AND THE RAW MATERIALS CONTAINED IN THE FORMULATION. THESE CERTIFICATIONS CONTRIBUTE TO THE PRODUCT’S INNOVATION AND ENVIRONMENTAL COMPATIBILITY. SUSTAINABILITY CERTIFICATIONS The product complies with the procedures, properties and values of EPD...

INSULATING SCREED ON UNDERFLOOR PIPEWORK SUBSTRATE THE SYSTEM ENSURES THERMAL AND ACOUSTIC INSULATION WITH MINIMUM THICKNESSES, WITHOUT OVERLOADING THE FLOOR OR CAUSING TECHNICAL PROBLEMS WITH MEASUREMENTS OF DOORS AND WINDOWS.

UNDERFLOOR PIPEWORK WITH INSULATING SCREED 2 WITH UNDERFLOOR PIPEWORK, THE BEAUTY OF THE DIATHONITE SCREED SOLUTION IS THAT IT OFFERS EXCELLENT THERMAL INSULATION WITH MINIMUM THICKNESS, A MERE 3CM. IN THE CASE OF UNDERFLOOR PIPEWORK, DIATHONITE SCREED CAN BE APPLIED ON TOP OF THE PIPE SLEEVES WITH A THICKNESS OF JUST 3 CM, WITHOUT ANY RISK OF CRACKING. No matter how well heated a room is, in case of traditional screed the indoor ambient will always have temperature differences between high and low areas in the room, creating the feeling of a cold floor and, thus a thermal imbalance. Slab...

INSULATING SCREED ON SLAB ON GRADE OR ON EXISTING FLOOR THANKS TO COMPLETE FUNCTIONAL COMPATIBILITY, THE DIATHONITE SCREED - WATSTOP SYSTEM IS A SMART AND FUNCTIONAL SOLUTION FOR APPLICATION OF AN INSULATING SCREED WITH MINIMUM THICKNESS DIRECTLY ON A SLAB ON GRADE OR ON AN EXISTING FLOOR, AVOIDING COSTLY REMOVAL OPERATIONS. a. Flooring b. Traditional screed c. Slab 20 If not suitably protected, a slab on grade can present problems of rising damp, leading to the appearance of damp spots, heat loss, a cold floor and the formation of condensation on the floor surface. Slab/Existing floor...
