Knauf Dritherm Cavity Wall Slab 37 Standard

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.

Guarantee

Worked for only 4 months. Now produces metal shards. Dangerous
Pros: Can be used with one hand. I bought this to have after surgery that left me without use of one arm for a few months. The light blinks when you need to charge it. Only needs a 2-3 min charge for enough juice to open a can. Cons: IT QUIT CUTTING CORRECTLY AFTER 4 MONTHS. I now have to use both hands to hold it in place to get it to latch on to the can. It also requires a few rotations around the top to cut through the seal, resulting in METAL SHARDS! The metal shards are super sharp and almost invisible. I stabbed myself with one enough to draw blood. This is dangerous as the metal could fall into the food when pouring from the can.

Can opener
It doesn't shut off by itself when done and doesn't shut off when I push the button, so after a while it will shut off but when it wants too after you take it off the can ,like 30 seconds. But I do like the way it cuts, a clean cut and lid removal nice.

Great opener
Color: Blue
Had a battery operated can opener before and was always changing the batteries. Love the safety cut and this works great now that I can just charge it with my phone charger. Fits in my drawer so no counter space used
