The RW5 range of insulation is made of high-quality resin bonded slabs which are available in a range of densities and thicknesses that are designed to be used in a wide range of applications including walls, floors, roofs and more. The RW range can be customised with mineral black tissue (60gsm), mineral white tissue (100gsm), and aluminium foil facings, made to order.

The RW5 is 600mm by 1200mm, available in thicknesses from 25mm and 150mm. With a thermal conductivity of 0.035W/mK and a density of 100kg/m3.

The advantages of Rockwool RW5 include:

  • Excellent thermal, acoustic and fire insulation
  • Water repellent and non-hygroscopic
  • Resists high temperatures
  • Easy to handle and install
  • Cost effective
  • No maintenance
  • Durable/ Long lasting

The durability of this product gives you high-quality insulation that is long-lasting and will continue being effective for as long as the building/ structure is intact. These slabs are extremely lightweight and be can cut to any size required using a sharp knife which can make transportation and application of the product simple and easy.

Acoustic Performance: Rockwool products work in two ways to reduce noise which include either absorbing the sounds at the surface or impeding the transmission of sound through an element of the structure. The way Rockwool RW slabs are made, make them ideal for use as a sound absorber, with characteristically high coefficients over a wide frequency range. When thicker Rockwool is used and paired with a sheet of plasterboard the noise control can be improved further. These noises include conversation, video equipment, mechanical rooms, and ventilation systems.

Fire Reducing: RW5 has fire reducing qualities and will not burn or smoke which provides extra protection and reduces damage and fire spreading within houses and buildings.

Water Repellent: Rockwool RW5 also has water repellent qualities that can prevent moisture building up which can be the cause of damp, condensation and rot that can damage the property’s structure and affect the performance of the insulation.

Thermal Performance: Rockwool is mineral wool that provides insulation to the building/ structure by reducing the air flow throughout the building/ structure. Its high thermal efficiency can help reduce energy bills for heating and cooling in residential and commercial buildings. This is due to the outstanding thermal resistance of the wool used in RW5.

Rockwool RW5 can be installed in a range of methods. These methods include:

  • Walls – metal partitions
  • Roofs
  • Floors
  • Partition panels
  • Boiler rooms
