System components
Danskin Park Bearers
Park Bearers comprise softwood battens 47mm (Nom.) wide by 1800mm long with a specially developed resilient foam strip 9mm thick adhered to the underside. They can be preservative treated if required. Standard heights including the 9mm insulant are 31mm, 45mm, 54mm, 61mm and 70mm. Other sizes are available to order.
Danskin Flanking Strip
This is placed at the perimeter of each floor. The 6mm thick preformed “L” shaped acoustic foam is supplied in strips 1.8m long and packed in bags containing 100 linear metres. The innovative “L” shape makes the flanking strip easy to fit and one size fits all floors. It is lightly trapped between the bottom of the skirting and the top of the flooring board with the excess neatly trimmed off.
Danskin Acoustic Quilt (As required)
Where required to achieve a particular acoustic performance Danskin can supply acoustic quilt. 25mm thick, the quilt has a density of 36kg/m2 and is paper faced on one side. Each roll is 1200mm wide x 10 metres long.
