Isolatiemes KWB 015920 270 mm – KWB gereedschap voor het snijden van isolatiematerialen

The KWB Insulation Knife 015920 is a 270 mm hand tool designed for cutting insulation materials with precision and control. Featuring a long 270 mm blade, the tool is intended to make straight, even cuts in mineral wool, foam boards and other common insulation products used in construction and renovation. The knife balances cutting length with hand-operated control to help users achieve clean edges and faster fitting of insulation sheets and panels.

Advantages

The extended blade length enables long, continuous cuts that reduce the need for repeated passes and improve cutting consistency. Its ergonomic handle provides secure grip and safer handling during manual cutting tasks. The tool’s design focuses on delivering straight cuts across full insulation widths, helping to minimise waste and speed up installation work.

Key specifications

How to use

Place the insulation material on a stable surface and mark the cut line. Hold the knife with a firm grip and align the blade along the marked line. Apply steady pressure and draw the blade through the material in a single smooth motion when possible, or use multiple controlled passes for thicker sections. Maintain a consistent angle to ensure straight edges and check the fit against adjoining panels or framing as you work.

Recommendations

Use appropriate personal protective equipment such as gloves and eye protection when cutting insulation. For denser or thicker insulation, make several light passes rather than forcing the blade in one stroke. Keep the blade clean and replace it if it becomes dull to maintain cutting performance and reduce material tearing.
