External Wall Insulation allows a lot of flexibility when detailing such as corner quoins, window bands, keystones etc. This requires some additional work, but RMC Ecobuild’s skilled team are happy to create these features where required.
RMC Ecobuild primarily use GRC Concrete sills on our external wall insulation projects but we also offer Powder Coated Aluminium Sills as an alternative. The GRC sill is simply fitted over your existing sill to bring it out past the external insulation. Our preference is for GRC sills, due to their robust nature, durability and resilience in the Irish climate. They simply replicate traditional concrete sills at the end after external insulation is applied. See the schematic image of how they are fitted in place for further details.
