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.

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

Best Book on Improving Communication in Relationships

Such a helpful book, with concrete tips for improving communication in relationships. I find myself returning to this book whenever things become challenging in a relationship. I also attended a retreat based on the book’s teachings. Incredibly helpful.

Interesting, but not empirically validated, and written explicitly for straight people (why?!)
Format: Kindle
This one’s the 500-pound gorilla of the healthy-couple self-help genre, with thirty years in print, scores of Oprah appearances by the authors, thousands of therapists practicing the Imago framework. The main thing that I need to tell you about this updated edition, from the year 2019, is that it does not mention or acknowledge the existence of queer or same-sex couples even one time. In fact, it really doubles down on the husband and wife stuff, takes gender roles pretty seriously, which is not a thing I realized we did anymore, except as a joke. Anyway, talking only to straight people is not too relevant to my interests, and while the conservative Christian viewpoint is pretty subtle in the advertising, just be aware of that PROBABLY NOT ACCIDENTAL omission going in, queer friends. (This is made even more impressive by the fact that the heart of the Imago approach is based on childhood trauma, about the ways in which our parents caused us to suppress or hide or ignore parts of ourselves in order to be accepted and loved. Just let that sink in, because I’ve been reading this book for the past week and I am still reeling from the irony that people who have been thinking for the past three decades about the ways that parents cause trauma to kids by failing to accept parts of them have missed the VERY OBVIOUS AND RELEVANT EXAMPLE of queer folks.) That aside, for me the book was a mixed-bag of some interesting and provocative ideas (I’d put these in the category of poetic notions, or interesting narrative ideas), alongside some really kooky 20th century neo-Freudian stuff (rooted in part in Freud’s theory of repetition compulsion.) I’m no fan of Freudian approaches, and after I started this book, I decided to see how empirically-validated this Imago approach is: based on what I found, there seems to be basically no evidence that this therapy is effective. Am I glad I read it? I think so?? It was thought-provoking, with the pretty significant grain of salt that there’s not much evidence to support that Imago therapy is much better than doing nothing at all. Also, I feel a little gross giving my money to relationship experts who (in 2019!!)) won’t even acknowledge the existence of queer people, even when doing so would obviously strengthen their core arguments and provide better examples than some of the meek ones they give.
