Description

Knauf Dritherm Cavity Wall Slab 37 Standard is a slab of non-combustible, glass mineral wool with a water-repellent additive, designed for reliable and long-lasting effective insulation. They can be used to either full fill or partially fill wall cavities in buildings up to 12 metres high.

Knauf Dritherm Cavity Wall Slab 37 Standard is created with a special additive to become water repellent, with Slab 37 Standard having a thermal conductivity of 0.035 to 0.037 W/mK on average. These long-lasting slabs are designed to not sustain vermin, are odourless, and do not encourage the growth of fungi, mould or bacteria within your wall cavity.

The slabs have no vapour resistance and allow for vapour to freely pass through the cavity slab, with slabs forming together to leave no air cavities within the build. Knauf Dritherm Cavity Wall Slab 37 Standard is available to purchase from BSO in sizes from 85mm to 100mm x 1200mm.


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.

Very Bright, Easy to Put Up / Take Down
Color: White, Color: White
This light is very bright, and more than meets our needs. In addition, it has a nice easy to use latch that allows you to quickly put it on and take it off. It takes 4 batteries, which is a bit more than most, but given the brightness and number of LEDs, it seems to make sense. So far, we’re beyond thrilled to have such an affordable option that made our patio more usable at night.

Whish it was brighter
Color: White
It is ok, but I thought it would illuminate better. It provided some light right underneath, but it does not open up more lighting around. It barely expends to the whole length of the table.

Excellent lighting
Color: Warm
Highly recommended! I actually reordered one because I forgot one night to bring it in, then a severe storm came through and stole the umbrella, turning it upside down in the yard. Water got into the battery bays, so they rusted. I'm sure other connections inside rusted too, because after cleaning the contacts, I could not get the light to work again. But the reason I purchased a new one is because it looks so classy. Its warm light can be adjusted to three levels just by pressing the On button through the levels. Very simple. The ambiance it provides is lovely! Next to the On button is the clip that flips open to swing open the light. Place the light around the umbrella pole and snap shut the clip. The light is secured, but you can also slide it up or down to whatever height you prefer. It still remains stable and in place until you move it again. Until I left my first one out in the rain, the light worked beautifully and reliably, as does its replacement. Battery life is excellent unless you forget to turn off the light. I can't tell you exactly how long they last because inevitably after a few weeks, I do forget to turn it off. This is an inexpensive and beautiful upgrade to your patio experience. Excellent value, excellent quality, excellent lighting.

Great light, great price!
Color: White, Color: White
I'm a Carnivore who does all of my meat and fish cooking outdoors, adjacent to my kitchen. For the winter, I've put up a half-umbrella to keep the rain off of my cooktop. This light rounds out the kitchen by providing GREAT light for my alfresco kitchen. It works like a charm and is easy on the batteries.. I LOVE it!

Good price, easy to install
Color: Warm
First, the price is right. It is easy to install. My biggest problem was within a few hours, one of the bulbs already burned out. We are still using it and the rest work great.
