Why ICF is gaining ground
Insulated Concrete Formwork (ICF) construction is growing in popularity across Ireland thanks to its speed, strength, and high energy efficiency. Once the ICF walls are poured and cured, the exterior finish becomes critical for both performance and appearance. That’s where Baumit renders and finishes come in.
- Fast build: ICF blocks slot together quickly and are then filled with concrete.
- High insulation: Built-in EPS forms give excellent thermal performance.
- Strong & airtight: Solid concrete core provides durability and airtightness.
- Finishes: Can cater for a range of finishes.
Render compatibility with ICF
ICF needs a finish that adheres well to the EPS surface, resists cracking, and protects against Irish weather. Baumit Render systems are ideal because they are designed for external insulation substrates, including ICF. This suitability is backed by Baumit NSAI, ETA, BBA & KIWA certifications.
Baumit render options for ICF
- Baumit StarTop: Enhanced silicone-based render. Premium protection against algae and mould. Ideal for harsh and coastal environments.
- Baumit SilikonTop: Silicone-based render that is water-repellent and weatherproof.
- Baumit CrystalTop: Outstanding durability and Baumit’s premium render for dirt and extreme conditions.
- Baumit systems: Can also cater for Dry Dash, Brick Slip, and more.
Design & detailing considerations
- Ensure ICF is installed as per manufacturer details.
- Always use NSAI-certified systems and trained installers for ICF finishes.
- Pay attention to junctions, reveals, DPC, and window sills—ICF requires the same detailing care as EWI.
