The Boyne House
Brú na Bóinne is one of the most important archaeological sites of prehistoric origin in the world: it is located in the valley of the River Boyne in Ireland, about 40 km from Dublin. It has been a World Heritage Site since 1993 and is one of the most important archaeological sites of prehistoric origin in the world.
The technical pillars of the intervention
During 2019 the archaeological site was the subject of acoustic and aesthetic improvement interventions. The works were concentrated above all in the part that includes the entrance, the museum complex and the refreshment area.
In these areas of the structure the cork-based sound-absorbing mortar Diathonite Acoustix + it was chosen for its acoustic properties and its porous appearance. In some cases the cycle was completed, in black and white colors, with the lime-based paint Limepaint .
NRC
0.75
The low diffusivity value indicates a high degree of heat insulation and therefore greater comfort and savings for summer cooling
Density
400 ± 30 kg/m3
The lightness of the material made it possible not to weigh down the walls of the structure
Reaction to fire
Class A1
The special formula with cork microparticles makes the material fireproof and perfect for fire prevention interventions.
The application, entirely on the ceiling, was carried out using a plastering machine which made it possible to obtain a thickness of 3 cm, accompanied by the plaster holder net Polites 140 and the waterproofing in counterthrust Watstop, as the ceilings are below ground level.
Used products
Diathonite Acoustix+
Acoustic spray-applied plaster for sound absorption and insulation, made of natural raw materials such as cork, natural hydraulic lime, clay and fibers, suitable for applications onto walls, ceilings, rounded surfaces: it absorbs more than 80% of sound waves.
Polites 140
Glass-fibre armor to be used as mesh for internal and external plasters (Diathonite Line); to prevent cracks formation onto inconsistent supports or caused by eventual substrate structural movements; to improve plasters adhesion on many kind of different materials.
WATStop
Waterproofing in both negative and positive pressures, with an excellent resistance of up to 9.5 ATM. Made of three components, the material is perfect for underground walls, garages, cellars and concrete floors, to avoid any problem of rising dampness.
Limepaint
Liquid water based paint, highly covering and breathable, made of lime, to use as finish for walls and ceilings. It is the ideal solution to finish Diathonite plaster because thanks to its high breathability it contributes to the hygrometric balance of premises, avoiding any risk of mould and contributing to indoor comfort.
