What motivated us to develop the MG-1900 boards?

Nutec Mineral Grade MG-1900 Board was designed specifically to compete with mineral wool board.

Development of this product started in 2019 and it was introduced at the end of the same year. Sales have substantially grown in the last 2 years.

Advantages of the MG-1900 Boards

Some relevant benefits of these products are:

1.- Higher strength, better durability and insulating properties with higher operating temperatures

Mineral wool board has a use temperature to 700ºC (1,292ºF) and will start to deteriorate above 700 C, whereas MG-1900 board has a use temperature to 1,100ºC (2,012ºF).

2.- Water repellent coating

Available with a water repellent coating for high humidity operating environments that provide increased durability.

3.- Variety of thickness available

MG-1900 boards range in thickness from ½” to 3” in a single piece, unlike mineral wool boards with thinner thicknesses that require layering several pieces to achieve an equivalent thickness. One piece construction provides greater strength and better performance.
