Ecotherm Eco PIR Full Fill Cavity Insulation – All Thicknesses



Eco-Cavity Full Fill


Eco-Cavity Full Fill is a cavity wall insulation board with a thermal conductivity of 0.022 W/mK. Eco-Cavity Full Fill is ideal for use with masonry walls and is suitable where the requirement is for insulation to completely fill the cavity, whilst maintaining a residual 10 mm cavity to resist moisture transfer.

Product Highlights

  • Suitable for use in full fill cavity wall applications, allowing for optimal thermal performance to be met.
  • Tongue and groove edges allow for easy installation
  • Lightweight insulation – easy to transport
  • High performance rigid polyisocyanurate (PIR) insulation core
  • Aluminium composite foil facing to both sides

Application – Eco-Cavity Full Fill allows users to optimise the full cavity with high performing thermal insulation, meaning U-values and Building Regulations can be met without altering standard construction designs.

Thermal Conductivity – the thermal conductivity (or lambda value) illustrates how well a material conducts heat. The lower the thermal conductivity, the better the insulator.

Eco-Cavity has a thermal conductivity of 0.022 W/mK across all thicknesses.

Insulation Material – Eco-Cavity is a high performance rigid thermoset polyisocyanurate (PIR) insulation.

Facings – Eco-Cavity has an aluminium composite foil on both its inner and outer facing. This is bonded to the insulation core during manufacture.

Dimensions – 1200mm x 450mm

Thicknesses – Eco-Cavity Full Fill is available in the following thicknesses: 90 mm, 115 mm and 140 mm.

Pack Quantities – 90mm 4 boards per pack, 115mm 4 boards per pack, 140 mm 3 boards per pack.

Fire Class – Reaction to fire is measured with a Euroclass rating. ecotherm-eco-cavity-full-fill-brochure-en-gbUnder System 4 AVCP, Eco-Cavity Full Fill has a Euroclass rating of F.
