A wrong measurement on site doesn't just cost a reorder. It stops the job, wastes skilled labour, and compromises building safety. Here is how we eliminate the guesswork.
// B2B Feedback
We work with leading residential developers, external wall insulation (EWI) installers, and commercial contractors across Ireland.
"Fabricator.ie and the Cills app have completely transformed our window sill specification. By scanning reveals and locking in 3D dimensions, we eliminated ordering errors entirely. Site measurement and fitting services are flawless."
"For retrofitted external insulation, reveal depths vary constantly. The ability to configure deep reveal aluminium cills (350mm+) with exact welded stop-ends and receive them in 3-5 days is a game changer for our schedules."
"We specify Fabricator.ie for our high-end residential and commercial projects. Their 2mm marine-grade alloy and Qualicoat powder coating finishes meet our strict specifications for coastal wind-load and salt-spray protection."
// Blog & Resources FAQs
We cover material specifications, marine-grade alloys, external insulation reveal weatherproofing, secret-fix capping installations, and CNC fabrication techniques.
We publish technical articles and installation guides monthly to keep contractors and architects updated on Irish building regulations and weathering details.
