Mineral-wool stitching mats on synthetic binder MMPB
ДСТУ Б В.2.7-167:2008
Stitching mats are made of mineral wool (BMT, VM) of brands M-30, M-40, M-50, M-60, M-70, M-80, M-90, M-100, M-125. They are a heater in the form of rolls: without lining, with one-, two-sided lining of fiberglass, metal mesh, fiberglass mesh, fiberglass. Stitched with glass roving, glass fiber.
Dimensions
Length – 2000-4000mm
Width – 1000mm
Thickness – from 40 to 120mm
Sizes of mats can be agreed.
MMPB mats are a non-combustible heat-insulating material, chemically resistant, non-toxic, do not rot, are an unacceptable environment for microorganisms and rodents, do not absorb moisture. Mats have good thermal insulation properties. They are an inexpensive, easy-to-install heat-insulating material.
Scope and features of application:
- As a heat-insulating material for pipelines of cold and hot heat, water supply.
- Thermal insulation of boiler equipment.
- As unloaded thermal insulation of pitched roofs, attics, ceilings.
