How to Cut Fiberglass
Intro: What Cuts Fiberglass?
Fiberglass is strong, lightweight, and versatile — which makes it great for things like insulation, boat parts, panels, and more. If you’re wondering what cuts fiberglass best, it’s important to know that cutting fiberglass isn’t as simple as slicing wood or plastic. Among various options, laser cutting fiberglass is a precise method, but regardless of the technique, cutting fiberglass can pose serious health risks if you’re not careful.
So, how do you cut it safely and effectively? Let’s walk through the three most common cutting methods and the safety concerns you need to be aware of.
Best for: Clean edges, detailed designs, less mess, and overall safety
If you’re looking for a method that’s precise, efficient, and safer than others, laser cutting fiberglass is the way to go. Using a CO₂ laser, this method cuts the material with heat instead of force — meaning no blade contact, less dust, and incredibly smooth results.
Why do we recommend it? Because it gives you excellent cutting quality with minimal health risk when used with a proper exhaust system. There’s no physical pressure on the fiberglass, and the precision is perfect for both simple and complex shapes.
User tip: Always pair your laser cutter with a fume extractor. Fiberglass can release harmful vapors when heated, so ventilation is key.
2. CNC Cutting (Computer-Controlled Precision)
Best for: Consistent shapes, medium to large batch production
CNC cutting uses a computer-controlled blade or router to cut fiberglass with good accuracy. It’s great for batch jobs and industrial use, especially when equipped with a dust collection system. However, compared to laser cutting, it may produce more airborne particles and require more post-cleanup.
User tip: Make sure your CNC setup includes a vacuum or filtration system to reduce inhalation risks.
3. Manual Cutting (Jigsaw, Angle Grinder, or Utility Knife)
Best for: Small jobs, quick fixes, or when no advanced tools are available
Manual cutting tools are accessible and inexpensive, but they come with more effort, mess, and health concerns. They create a lot more fiberglass dust, which can irritate your skin and lungs. If you go this route, wear full protective gear and be prepared for a less precise finish.
User tip: Wear gloves, goggles, long sleeves, and a respirator. Trust us — fiberglass dust is not something you want to breathe in or touch.
If you’re trying to decide how to cut fiberglass for your next project, here’s our honest recommendation:
Go with laser cutting if it’s available to you.

Yes — if you’re not careful. Cutting fiberglass releases tiny glass fibers and particles that can:
• Irritate your skin and eyes
• Trigger respiratory problems
• Cause long-term health issues with repeated exposure
