POLYTECH®MP Thermally-Insulating Masonry Mortar

It is a two-component mortar with above-average thermal insulation performance. It is intended primarily for the construction of single-layer walls.

• Component A: a cement-and-lime binder, regranulated (or granulated) polystyrene foam, mineral additives and chemical admixtures
• Component B: construction grade sand with a grain size of up to 0.2 mm, PN-EN 12620:2004-compliant, to be used as a filler.

Intended use

• construction of residential buildings, industrial premises and public utility buildings,
• inside and outside buildings, except for surfaces exposed to moisture (cellar walls, foundations below the frost line),
• connection of bricks, building blocks or other ceramic or concrete elements.

Features

• The thermal insulation consistency of the wall is increased, with λ≤ 0.2W/m·K (for the binding material).
• Thermal bridges are either eliminated or significantly reduced.
• The compressive strength after 28 days is good: category M5.
• The material adheres to the surface well.
• It is a malleable material.
• The process of preparing the wet mortar is low labour intensive.
• It can be used for bricklaying work using traditional tools and techniques.

Process parameters

• temperature of application (except for the surface and the environment): +50C°-250C°
• recommended mix proportions: 8 (± 5%) litres of water for each pack of component A (18 kg) and each pack of component B (10.5 L)
• mixing time: 4 min
• suitable for use when mixed with water: 2-3 hours
• recommended binding layer thickness: approx. 1 cm
