Building Regs. only came in in '92 I believe.Hollow blocks in a gable wall? I'm pretty sure this would have been against the building regulations even 30 years ago
Just my tuppence worth but to my knowledge (and certainly last time I checked) there are no external insulating and finishing systems (EIS as these systems are technically called) that have an Irish Agrement Certificate- which is why these systems are not approved by Homebond. I'm no big fan of Homebond- but if EIS aren't good enough for them i'd be more inclined to look at the reasons why. EIS systems are a quick fix solution which are not suited to our climate- driving rain and high levels of precipitation are not kind to these systems. Surface crazing can allow minute amounts of water to penetrate the insulation, this combined with freeze/ thaw action can lead to a rapid disintegration of the render and insulation over time. Also mechanical damage is a huge problem- if damage isn't properly repaired and done so quickly water ingress will accellerate the breakdown of the system.

An IAB cert would give me more peace of mind and an assurance that a particular product was suitable for use in the Irish market. A product or system that performs well in Germany (to DIN standards etc) may not translate in terms of performance in the Irish context. Our expectations of building performance, maintenance cycles etc are very different from our European neighbours. And if you want Homebond approval you can forget about EIS- unless you can produce an IAB cert.
