DriTherm Cavity 35

DriTherm Cavity 35

DriTherm Cavity 35 are rolls of non-combustible, water repellent, glass mineral wool. They are 455mm wide to suit standard vertical wall tie spacings, ensuring a closed joint with adjacent slabs.

Performance

Thermal

DriTherm Cavity 35 Rolls have thermal conductivity of 0.035 W/mK.

Fire

DriTherm Cavity 35 Rolls are classified as Euroclass A1 to BS EN 13501-1.

Description

DriTherm Cavity 35 Rolls are rolls of non-combustible, water repellent, glass mineral wool. They are 455mm wide to suit standard vertical wall tie spacings, ensuring a closed joint with adjacent slabs.

Benefits

  • Excellent thermal and fire performance
  • Water repellent
  • Slabs ‘knit’ together, thus eliminating air gaps between adjacent slabs

Application

DriTherm Cavity 35 Rolls are for the thermal insulation of masonry cavity external walls and are installed to fully fill the cavity. They are ideal for use in buildings up to 12m high in any exposure zone and for use in multi-storey applications up to 25m in height.

Environmental

DriTherm Cavity 35 Rolls represent no known threat to the environment and have zero Ozone Depletion Potential and zero Global Warming Potential.

ECOSE® Technology

Knauf Insulation mineral wool products with ECOSE® Technology benefit from a no added formaldehyde binder, which is up to 70% less energy intensive than traditional binders and is made from rapidly renewable bio-based materials instead of petroleum-based chemicals.

The technology has been developed for Knauf Insulation’s glass and rock mineral wool products, enhancing their environmental credentials without affecting the thermal, acoustic or fire performance. Insulation products made with ECOSE Technology contain no dye or artificial colours.

Standards

DriTherm Cavity 35 Rolls are manufactured in accordance with BS EN 13162, ISO 50001 Energy Management Systems, OHSAS 18001 Occupational Health and Safety Management Systems, ISO 14001 Environmental Management Systems, and ISO 9001 Quality Management Systems, as certified by Bureau Veritas.

Durability

DriTherm Cavity 35 Rolls are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

Moisture resistance

DriTherm Cavity 35 Rolls will not transmit water to the inner leaf. Nor will they transmit moisture by capillary action across the cavity or from below damp proof course level. 

Vapour resistivity

DriTherm Cavity 35 Rolls offer negligible resistance to the passage of water vapour and have a water vapour resistivity of 5.00MNs/g.m.

Handling and storage

DriTherm Cavity 35 Rolls are easy to handle and install, being lightweight and easily cut to size, where necessary. They are supplied in polythene packs which are designed for short term protection only. For longer term protection on site, the product should either be stored indoors, or under cover and off the ground. DriTherm Cavity 35 Rolls should not be left permanently exposed to the elements.
