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.

Genuinely One of My Favorites Sunscreens in Existence
I use stick sunscreen around my eyes on a daily basis. It's less likely to run into my eyes and sting than regular sunscreen. However there can still be issues. Sometimes it still irritates my eye area, looks weird under makeup, pills, or (as with most mineral sunscreens) leaves a weird cast around my eye area. I was very pleasantly surprised by this sunscreen. It feels like very light weight balm that feels heavenly on the skin. It isn't sticky, greasy, and doesn't have a weird sunscreen smell. It's moisturizing without being too moisturizing, if that makes sense. Given the price point I am absolutely amazed at the quality. If you repackaged this sunscreen and sold it as a luxury product I would be none the wiser. This will be a new staple in my daily routine.

Good for on-the-go sun protection
This is a solid purchase because the compact size makes it easy to carry around. The velvety finish feels nice on the skin and blends in clear, which is great for all skin tones. It’s also quick and easy to apply.

I recommend this product for daily use
I recommend this product because it's gentle on my skin and works well for daily use. The compact size makes it easy to carry around, and it provides good UV protection with a velvety finish. Plus, it layers under makeup nicely and adds a subtle glow. The moisturizing formula keeps my skin hydrated. Overall, a great travel-friendly sunscreen that's non-comedogenic and suits all skin tones.

Great appearance but fumes burn eyes
I like the easy application and shear appearance. Slightly dewy look. I have been using for over a year but had to stop. Each time my eyes would become more sensitive to the “fumes” wafting off my cheek bones. Unfortunately I bought three sticks because I liked it so much, but now I just apply it to my legs.
