Insulation Saw Blades
Insulation saw blades are designed to slice through fibrous and foam materials without tearing or binding. Ideal for PIR board, Rockwool, fibreglass and acoustic slabs — these blades cut fast, clean and with minimal mess on site.
What Are These Blades Used For?
Perfect for shaping, sizing and trimming insulation products on site:
- Mineral Wool – Cleanly slice through Rockwool and glass wool batts
- PIR & Foam Boards – Cut dense PIR, Celotex or Kingspan with smooth edges
- Acoustic Panels – Shape soundproofing boards for tight cavity fits
- General Site Insulation – Fast-fit foam, fibreglass or rigid insulation for walls, roofs and floors
Used By:
- Builders and retrofit installers fitting floor and wall insulation
- Roofers cutting foam and acoustic slabs to size
- Dryliners and HVAC trades shaping duct and ceiling insulation
Choosing the Right Insulation Blade
Match the tool, material and blade tooth type to reduce snag and dust:
1. Recip vs Hand Saw
Use recip blades for quick, powered cuts. Hand blades offer control for tight areas or delicate acoustic panels.
2. Tooth Design
Wave-set teeth glide through fibrous materials. Serrated or scalloped edges prevent snagging on PIR and foams.
3. Blade Length
Longer blades (300mm+) help cut thick slabs in one pass. Shorter blades give control in shallow installs or ductwork.
Insulation Saw Blade FAQs
Can I use a standard recip blade on insulation?
You can, but it’ll likely snag or tear the material. Insulation blades have wave or scalloped teeth to minimise mess and ensure accuracy.
What blade is best for Rockwool?
Use a wave-set or serrated blade around 300–400mm long. These handle dense fibre and reduce airborne particles when cutting.
Can I cut foam board with a hand saw?
Yes — use a fine-toothed or scalloped blade to avoid crumbling and ensure straight, dust-free cuts.
Are these blades reusable?
Yes — insulation blades typically last multiple installs, especially when used with care and kept clean of adhesive residue.
