Insulation Batts vs. Other Types of Insulation: Which Is Best for Your Project?

Abner Cruz Herrera • May 21, 2025

When planning an insulation upgrade, choosing the right material is crucial. In this guide we’ll compare high-performance insulation batts to other common options—focusing on what Construct Ramsay offers—so you can select the best solution for your home or commercial build.


What Are Insulation Batts?

Insulation batts are pre-cut, rectangular slabs designed to fit neatly between studs, rafters and joists. Construct Ramsay supplies CSR batts (backed by a 70-year warranty) as well as top brands like Kingspan and Bradford, all with a minimum rating of R6.0 HP. These products deliver excellent thermal performance, fire resistance for bushfire-prone areas and acoustic insulation.


How Do Insulation Batts Compare to Rigid Foam Boards?

Rigid Foam Boards

Best for: Flat surfaces, under slabs or externally on walls

Rigid boards such as Kingspan Kooltherm or Bradford Thermaboss offer very high R-values in a slim profile—ideal under concrete slabs or over timber cladding. However, they tend to be more expensive per m² and require precise cutting and fixing.
✔️ High thermal resistance per thickness
❌ Higher material cost
❌ Professional installation only


Why Insulation Batts Are the Most Versatile Option

Insulation batts deliver the best balance of performance, cost and installation speed—especially for Melbourne’s climate and construction styles.
🏗️ Professional fit-out: Installed by licenced contractors
💲 Cost-effective: Competitive rates on R6.0 HP and above
🔥 Fire-rated options: Compliant with Australian bushfire standards
♻️ Multiple brands: CSR (70-year warranty), Kingspan & Bradford

Location Ideal Batt Type
Walls Thermal & acoustic
Ceilings Thermal & fire-rated
Underfloors Moisture-resistant batts
Between floors Acoustic batts

Which Should You Choose?

If you want a cost-effective, high-performance insulator with straightforward installation by professionals, batt insulation is your all-rounder. For specialised applications under slabs or slim external retrofits, rigid foam boards may be more suitable.
