Description

DriTherm Cavity Slabs are semi-rigid or rigid slabs of non-combustible, glass mineral wool with a water-repellent additive. They are 455mm wide to suit standard vertical wall tie spacings, ensuring a closed joint with adjacent slabs.

DriTherm Cavity Slabs have a special additive to make the product water repellent and are produced in three grades:

  • DriTherm Cavity Slab 37 Standard has a thermal conductivity ranging from 0.035 to 0.037 W/mK
  • DriTherm Cavity Slab 34 Super has a thermal conductivity of 0.034 W/mK
  • DriTherm Cavity Slab 32 Ultimate has a thermal conductivity of 0.032 W/mK

DriTherm Cavity Slabs are for the thermal insulation of masonry cavity external walls, either partially filling or fully filling 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.

Standards

DriTherm Cavity Slabs are non-combustible inorganic glass wool, defined as mineral wool in BS 3533: 1981 and are manufactured in accordance with BSI Quality Assurance Standard BS EN ISO 9001: 2000.

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.

Vapour Resistance

DriTherm Cavity Slabs offer virtually no vapour resistance, allowing water vapour to pass freely through the slab.

Fire

DriTherm Cavity Slab is classified as Euroclass A1 to BS EN ISO 13501-1.

Benefits

  • British Board of Agrément approved for use in all exposure zones
  • Excellent thermal and fire performance
  • Water repellent

DriTherm Cavity Slab is certified by British Board of Agrément Certificate 95/3212 which approves its use in buildings up to 12m in height in any exposure zone, and in multi-storey applications up to 25m in height.

DriTherm Cavity Slabs have been used in many buildings over 25m in height, including exposed coastal sites. 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.

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 external cavity walls and to have a thermal conductivity of 0.032 to 0.037 W/mK at normal building temperatures. Masonry includes bricks, blocks and dressed and reconstituted stone. The guarantee is available by application from Knauf Insulation Ltd.

High Transfer, Bright Colors & No Ghosting
Size: 8.5"*14", Color: 150 sheets, Size: 8.5"*14", Color: 150 sheets
This HTVRONT sublimation paper 8.5x14 inch has been excellent for my sublimation projects. The 120gsm weight feels sturdy and feeds smoothly through my inkjet printer without jams or curling. It holds ink well, which helps produce clean, sharp prints before pressing. The transfer results are impressive. Colors come out vibrant and true, with strong detail and no dull or faded areas. I’ve had very little ghosting, and designs transfer evenly onto shirts, mugs, and other sublimation blanks. The claimed high transfer rate really shows in the final results. I also like the larger 8.5x14 size, which gives extra space for bigger designs or multiple smaller prints on one sheet. The paper releases well during pressing, leaving minimal residue and clean edges. Pros: ✔ Bright, vibrant color transfer ✔ Minimal ghosting or smudging ✔ Smooth printer feeding ✔ Great for shirts, mugs, and hard blanks ✔ Good value for the sheet count Cons: – Must be used with sublimation ink – Requires correct heat press settings for best results Overall, this HTVRONT sublimation paper is a reliable choice for anyone doing sublimation printing who wants strong color transfer, crisp detail, and consistent results. Great for both beginners and small business use.

Thin but with extra step works great
Size: 8.5"*11", Color: 150 sheets
It sublimated great but it’s thinner than what I normally use so it take an extra step to not have over lapping but it’s cheaper and you get more so definitely worth the price

My Go-To Sublimation Paper — Flawless Results Every Time
Size: 8.5"x11", Size: 8.5"x11"
This is hands down the best sublimation paper I’ve used and the only one I continue to buy. I get a perfect transfer every single time—no fracturing, no fading, and no uneven results. The paper dries fast, which makes my workflow so much smoother, especially when I’m producing items in batches. I use this regularly to make air fresheners and tote bags for my small business, and the color payoff is always vibrant and crisp. The transfer rate is excellent, and it works beautifully on light-colored, high-quality polyester and other sublimation-ready surfaces. If you’re a small business owner or crafter who values consistency, quality, and ease of use, this paper is absolutely worth it. I highly recommend it and will continue to repurchase.
