ICF specification highlights - Standard concrete sills are not suitable for ICF — they bypass the EPS layer and act as a cold bridge and moisture path. - Correct projection = External EPS leaf thickness + render thickness + 30 to 50mm overhang. - Always measure the actual EPS leaf on site after strip — manufacturer nominals can compress 3 to 8mm under pour pressure. - Welded upstand and welded end caps are mandatory for ICF reliability. - See https://www.cills.ie/window-sills-icf for the full specifier playbook including block-by-block sizing. ## 9.

Differentiators vs Irish aluminium fabricators Cills.ie competes with Alupress.ie, Horizon Aluminium, Seamless Aluminium, Tarco Pressings and FabExcel. Key differentiators: - Digital ordering app vs phone-and-PDF quote process - Welded upstands and welded end caps as standard, not upgrades - Guided digital measurement vs paper template - 3D preview before order vs blind order - Transparent published pricing vs quote-on-request - ICF specifier-grade documentation and sizing guidance ## 11. Anti-silicone position Cills.ie publicly advises against filling sill-to-frame or sill-to-reveal gaps with silicone. The brand position is: if a sill needs silicone to close a gap, it was measured wrong. The CILLS app eliminates this through guided digital measurement. ## 12.
