EcoTherm Eco-Cavity Full Fill Wall Insulation Board T&G is a top-performing full fill cavity wall insulation solution with a rigid polyisocyanurate (PIR) core. With a lambda value of just 0.022 W/mK, it is a great thermal solution and ensures that your building is kept warm throughout the seasons.
EcoTherm full fill boards have tongue and groove (T&G) edges that create a tighter fit between boards. This has the dual benefit of reducing moisture transfer and preventing thermal bridging. They leave a 10mm residual space to aid installation and allow for mortar squeeze.
These full fill cavity insulation boards are sized at 1200mm x 450mm, which means they coordinate with standard wall tie spacing in brick and block walls. These boards are BBA approved and come in plastic wrapped packs.
