Performance

Thermal

DriTherm Cavity Slabs have thermal conductivities ranging from 0.032 to 0.037 W/mK.

Fire

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

Benefits

    • British Board of Agrément approved for use in all exposure zones
    • Excellent thermal and fire performance
    • Water repellent
    • Slabs ‘knit’ together, thus eliminating air gaps between adjacent slabs



Application

DriTherm Cavity Slabs are for the thermal insulation of masonry cavity external walls and are installed to fully fill the cavity. They are approved 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 Slabs represent no known threat to the environment and have zero Ozone Depletion Potential and zero Global Warming Potential.

Knauf Insulation mineral wool products with ECOSE Technology benefit from a revolutionary, bio-based, formaldehyde-free binder technology, based on rapidly renewable materials, instead of petro-based chemicals. It reduces embodied energy and delivers superior environmental sustainability.

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 – the colour is completely natural.

Additional

Standards

DriTherm Cavity Slabs are manufactured in accordance with BS EN 13162, EN 16001 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 Slabs are odourless, rot proof, non-hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

Moisture resistance

Tests by the British Board of Agrément confirm that DriTherm Cavity Slabs 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 Slabs offer negligible resistance to the passage of water vapour and have a water vapour resistivity of 5.00MNs/g.m.

Guarantee

DriTherm Cavity Slabs are guaranteed* for 50 years to resist the transmission of liquid water from the outer masonry leaf to the inner masonry leaf in new cavity walls and to have a thermal conductivity of 0.032 to 0.037 W/mK at normal building temperatures

*Available by application to Knauf Insulation Ltd

Certification

DriTherm Cavity Slabs are certified by British Board of Agrément Certificate 95/3212. Approval can be sought from Knauf Insulation Ltd and the British Board of Agrément for DriTherm Cavity Slab’s use in buildings over 25m high.

Enjoyed by puppy
Excellent puppy teether. Stands up to games of tug-o-war, satisfies the need for chewing on the "bone" and she likes it when it's been cooled. I wet the fabric part before popping it in the fridge. So far, it's held up well to her sharp puppy teeth. Definitely a repeat purchase item.

Puppy is obsessed, so are my adult dogs!
These were a life saver while my puppy was teething. He absolutely LOVED these and somehow the little cloth attached to it held up extremely well. I'm not sure if it was the textures or the flavor/scent but this was by far his favorite toy. He's 6 months now and will always run to this. Our adult dogs have accidentally gotten ahold of these a few times and it holds up well to them too (thankfully). Super soft and great to also throw in the freezer to soothe their teeth while teething. This is a great value and if it's something that keeps the pup occupied, I'm all for it!

Probably best for medium to large dogs
I got these for my teething Japanese Chin pups & they can’t really chew the blue part because it’s too large for small dogs. I usually just barely wet the rag & wrap treats up inside, tucking it inside itself before freezing to make something more enriching for them. They like it overall.
