DriTherm Cavity Slabs are semi-rigid or rigid slabs 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 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.

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.

Great addition to our home
Model: Model B with Removable Tray
Putting together took a little time but instructions included were easy for me to follow. Putting the screws in for the shelves required a little work to get then started but nothing that I would say would be a problem to do. It is very sturdy and looks great in our room we are transforming into a hangout/bar area. I can't wait to get all my accessories in to add to it and display all my nice bottles I have. Great cart for the price.

My Cart Worked Out Perfectly For Me - Update: I got a second cart
Model: Model B with Removable Tray
Delivered sooner than promised. All pieces were present. All parts were in good condition. Assembly was done by a professional who thought the product was well done and needed very few adjustments. The cart rolls smoothly, is very sturdy, is a great size, looks attractive and is perfect for my needs. I would order one of these again. Update: I did get a second cart and I am just as happy with this second one as I have been with the first one.

Notice it is not real wood!
Model: Model B with Removable Tray
Easy to put together. The biggest complaint is it is not real wood. It looks like it is covered with contact paper!

Looks expensive. Wheels could be better.
Model: Model B with Removable Tray
This got RAVE reviews when I wheeled it into a neighbor’s Thanksgiving celebration. The guests thought it was WAY more expensive than I paid. That said, the wheels aren’t all that great; the cart got stuck going into and out of the elevator. I had to lift the cart to get it over the track. But overall, I really like it. One caution. Read the instructions carefully so that the wine racks fit. I didn’t assemble it correctly, and it became apparent when the wine racks would not fit. But I was able to quickly disassemble the necessary sections, and reassemble them quickly.
