NyRock® Rainscreen 032 is a stone wool insulation product specifically developed for use within ventilated cladding systems, as well as sealed systems such as curtain walling.


Manufactured using patented technology, NyRock Rainscreen 032 has a more efficient fibre structure that increases the density of air pockets trapped within each slab. This results in an improved thermal performance when compared to traditional stone wool products.


Once installed, the product’s high density works in combination with a factory applied water repelling agent to give improved resistance to rain ingress during construction.


The product can be fitted around brackets and other awkward details, and when tightly butted, adjacent slabs effectively ‘knit’ together to provide a continuous insulating layer, reducing heat losses that would otherwise be caused by gaps.


For optimum thermal performance in framed structures, combine NyRock Rainscreen Slab 032 with NyRock Frame Slab 032.


Features and benefits:

  • Low thermal conductivity of 0.032 W/m·K.
  • BBA pending.
  • Non-combustible Euroclass A1.
  • Independently tested acoustic benefits.
  • Water repellent yet breathable.
  • Can be recycled and reprocessed, reducing landfill costs, with zero ozone depletion potential (ODP) and global warming potential (GWP).
  • Stone wool is dimensionally stable and has been proven to provide the same performance for more than 55 years after installation.
  • Compatible with masonry restraint systems.


For use on steel frame, timber frame, or masonry walls in

conjunction rainscreen cladding:

  • Slabs should be close-butted at all vertical and horizontal joints. The horizontal joints of the insulation should be staggered in accordance with good practice.
  • Fixings should have a minimum head diameter of 70 mm. A typical fixing pattern has three fixings per square metre with one metal fixing at the centre of every slab.
  • The product should be cut and tightly fitted around cladding support elements.
  • For a typical installation, a breathable membrane is placed between the sheathing board and the product A vapour control layer (VCL) is placed between the plasterboard and the frame.


For use on steel frame or timber frame with a brick outer leaf:

  • The slabs should be close-butted at all vertical and horizontal joints, and at corners. The horizontal joints of the slabs should be staggered, in accordance with good practice.
  • Slabs should be carefully cut to fit around any protrusions into the cavity.
  • A VCL is placed between the plasterboard and the frame. A breathable membrane is placed between the sheathing board and the product.
  • The insulation should be installed to coincide with the frame, with retaining discs used in conjunction with the wall ties at no more than 600 mm horizontally and 450 mm vertically.
  • After each section of the leading leaf is built, excess mortar should be removed from the cavity face and mortar droppings cleaned from exposed edges of the installed board, before installation of the next run of boards.
