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.

Handling and storage

DriTherm Cavity Slabs 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 Slabs should not be left permanently exposed to the elements.

Commercial grade divider suitable for many needs
Color: Beige, Size: A-132''W-6 Panel
This item will be used at a future event where we need to separate a single locker room into two large areas, without any construction. This divider is perfect for the job because the partitions can be 1 to 6 panels and it will roll into place. When the event is over, the divider will fold/roll away and the locker room will return to its original design. The unit is very heavy, which will ensure that it is sturdy and stable. All the components arrived, wrapped in plastic to prevent damage. The screen material is a woven polyester in a cream color that will occlude any visibility but it may be possible to see shadows on the opposite side. The height is about 6ft, which would require a very tall person to "peep over" the divider. I needed a quality unit for this project and the frame, screens, and mobility will meet the needs. The divider is not the same as the small decorative dividers -- it is more of a commercial grade product, yet tasteful. If you want/need a small divider as an accent piece, this is not the best choice. This item could be used in a medical office, treatment/massage room, to divide an office room into two, or block a hallway in a building.

Great option for a professional looking backdrop
Color: Black, Size: B-102''-3 Panel
I decided to try these wall dividers for my home office space since it does not have a door. I wanted to have my video calls without the rest of the room in the feed to give it a more professional feel. These being on castors make them super easy to move into position and roll off to the side when not in use. They are stable, much more than the folding screens I have tried in the past. That they are connected by the middle piece and not the top/bottom of each other allows you to adjust the positioning to your needs. Overall, this did exactly what I needed and was an affordable option. I also like that they are highly portable: if you want to take them for a booth or event, the poles all disassemble into manageable lengths that easily fit in a car and take very little time to set up again. The only thing I would change is to include a bag to store them in for transportation.

if you are going to be moving them a lot, buy something more sturdy.
Color: Black, Size: Wheel-6 Panel
I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.
