Ursa 10 Diverso Loft Roll is a lightweight, non-combustible, unfaced glass mineral wool product. It has perforations enabling the width to be split to either 2 x 570mm or 3 x 380mm. Common applications are for use as loft insulation in ventilated and unventilated cold roof spaces.
When used in new buildings or upgrading existing buildings URSA 10 loft insulation is the most cost effective way to reduce heat loss through the roof and may be used in multiple layers to achieve very low U-values.
Length : 7.5m.
Width : 1.14m - perforated at 570mm (x2) and 380mm (x3).
Coverage : 8.55m2.
Thickness : 150mm.
Thermal conductivity : 0.044 W/mK.
Ursa : 10 diverso.
Fire rating : A1.
Non combustable.
To minimise the condensation risk a vapour control layer is required when insulating between the rafters at ceiling level, this can either be a polythene sheet (minimum 500g) or a foil-backed plasterboard. The use of the vapour control layer also creates an air barrier that helps to improve the air tightness of the building and so limit air infiltration. The type of roofing underlay should be carefully considered. Breathable membranes (Type LR) may not require roof space ventilation provided they are covered by BBA certification. More traditional bitumen or polythene based membranes (Type HR) require provision for eaves and ridge ventilation.
