Long utility blades for cleaner cuts

In construction environments, especially on job sites involving thermal and acoustic insulation, builders, roofers, and interior installers frequently rely on toothed and straight-edged long utility blades to cut insulation materials with precision and minimal waste. The correct choice of blade ensures cleaner cuts, better material fit, and ultimately a more energy-efficient installation.

Long toothed and straight blades to cut insulation materials

Buy toothed knife blade 261 for cutting insulation - use with Sollex utility knife 2000Toothed long blades such as Sollex art.nr 261 (180mm long) and 330 (330mm long) are commonly used for cutting insulation materials that are soft, fibrous, or semi-rigid. These blades are particularly effective in situations where standard straight-edged knives fail to deliver clean or efficient cuts due to the texture or thickness of the material. The teeth on these blades allow for controlled, low-dust cutting and help reduce material compression during cutting, which is essential for maintaining the insulating properties of the material.

Mineral wool, also known as stone wool or rock wool, is one of the most common insulation materials cut with Sollex toothed utility blades. Serrated utility blades 261 and 330 can pass through the material with less effort and produce more accurate results, especially when working with thick insulation batts. Similarly, glass wool, or fiberglass insulation, benefits from the use of these toothed blades. The serrated edge reduces fiber scattering and enables straighter cuts without deforming the soft layers of insulation.

Wood fiber insulation is another material where toothed long utility blades are especially useful. The toothing on the blade helps maintain control and precision, reducing edge damage and preserving the integrity of the panel. 

Natural fiber insulation materials such as hemp, flax, or cotton insulation, and recycled fiber insulation, such as cellulose-based mats, are often used in sustainable construction and cut with Sollex toothed utility blades. These materials tend to fray when cut with straight blades, so the sawing motion offered by a toothed cutting edge is more suitable.

While toothed blades are highly effective for the above types of insulation, they are generally not recommended for rigid foam materials such as extruded polystyrene (XPS), expanded polystyrene (EPS), polyurethane (PU), or polyisocyanurate (PIR). These materials are more brittle and can chip or crumble when exposed to a coarse blade. In such cases, use Sollex long straight utility blades art.nr 251 or hot wire cutters, which are typically more appropriate.
