(3 Products)

EcoTherm Eco-Cavity Full Fill Wall Insulation Board T&G is a top-performing full fill cavity wall insulation solution with a fibre free rigid polyisocyanurate (PIR) insulation core and aluminium foil composite facing. Boasting a thermal conductivity of 0.022 W/mk, this product provides up to 60% improved thermal efficiency over competing insulation products of the same thickness. What's more, the boards comprise a tongue and groove edge design - this engineered jointing system aids installation and prevents thermal bridging.

The Eco-cavity full-fill insulation is perfect for insulating full fill cavity wall applications whilst maintaining a residual 10mm cavity. This residual space is essential as it aids in reducing the transfer of water and moisture - two things which can wreak havoc on your walls' structural integrity. As an added bonus, it also works to accommodate mortar squeeze. 


With Eco-Cavity Full Fill, you won't have to enlarge your cavity or wall width to make room for traditional, thicker insulation materials. This ensures users can maintain a smaller cavity while still adhering to current Building Regulations. 

EcoTherm Eco-Cavity Wall Insulation Specifications

EcoTherm Eco-Cavity Wall Insulation Boards ensure a continuous layer of insulation in cavities where heat retention is a main priority. 

For insulating internal walls, products like Rockwool RWA45 100mm are the insulation of choice due to their sound-deadening properties.

Let's check the specs:
