Screedflo dB easily achieves Robust Detail standard performance allowing you to obtain 2 Eco-points. However, the inclusion of an optional acoustic quilt also allows you to achieve the 8dB level required in the Code for Sustainable Homes, and obtain 3 Eco-points.
While Screedflo dB is significantly faster to install than current acoustic floor systems, the realities of site mean that typically only a proportion of any block of apartments can be released for work at any one time. Consequently, a normal phase will be around 400m2 to 500m2 at a time, or 6 to 8 flats. This would take approximately 3 days to complete.
Screedflo dB is installed as soon as the building is weathertight, so there is no plasterboard or other materials to damage during installation. The screed can be walked on 48 hours after being poured, with heavy traffic allowed four days later.
During the drying period the screed will require a surface sand if the floor is to have a bonded or adhered finish this will remove any surface laitance that may have formed, it will also provide the necessary key for the adhesive/primer. This can be carried out 1 - 2 weeks after the screed has been laid depending on site conditions. It is advisable to use a light industrial sander with integrated vacuum system to avoid dust inhalation. If a floating or non bonded covering is to be used then the requirement for sanding is at the customers’ discretion. N.B. sanding the floor will improve drying times as a textured surface provides a larger surface area to give off moisture.
Primers - When applying adhesives or cement based products such as levelling screeds and grouts, the screed surface must first be primed with an appropriate primer as recommended by the manufacturer.
Most manufacturers will only guarantee their finishes when used in conjunction with their own products.
The sales appeal and environmental credentials of underfloor heating make it an increasingly popular option for developers. However, it is not at its most effective in timber floors. Screedflo dB allows both electric and water based underfloor heating systems to be cast into the screed as currently done on ground floors. Dependant on the bore of the piping systems, this can often be achieved with no increase in screed depth.
The use of screed in the acoustic floor, even in timber frame buildings, results in prospective buyers feeling that they are walking on solid floors. Screedflo dB minimises any sensation of movement within the floor, and virtually does away with any noise resulting from that movement.
Screedflo dB helps the environment as well as building performance. Not only does the screed largely consist of recycled waste from the flue gas desulphurisation process at coal fired power stations, but because of the unique batching process used with Screedflo, the screed also uses at least 30% less water than alternative screeds. The dBoard itself, is also FSC certified.
