Intended use: SPIRAL mixer by COMENSAL, intended for mortars. Cup diameter 100 mm
Raw material: Made of steel. Coated with thick zinc for protection against rust.
Construction: The stirrer's cup is made of flat thick metal sheets twisted in a spiral towards each other. It is ruthless at work and willingly chosen by builders.
Recommended direction of mass movement: from the bottom up, which ensures reaching the lower layers of the mixed substance and its precise connection in the entire container with mixing water.
Mounting type: SDS
At other auctions, the same construction model of the stirrer with different diameters of the cup and the method of fastening

FAQ
Welcome to polystyrene insulation EPS boards FAQ! Here you'll find answers to our most asked questions. Still can't find quite what you're looking for, or have something we should know? Use Q&As section or send us an email, we're happy to help!
Q1: What are EPS polystyrene boards used for in external wall insulation?
A1: EPS (Expanded Polystyrene) boards are used as thermal insulation in External Wall Insulation (EWI) systems. They are mechanically fixed and adhesively bonded to external walls, then reinforced with basecoat, mesh, and decorative render to improve energy efficiency and façade appearance.
Q2: Is EPS insulation good for external walls?
A2: Yes â EPS is one of the most widely used façade insulation materials because it offers: - Excellent thermal performance - Lightweight handling - Cost efficiency - Easy cutting and installation - Compatibility with most render systems
Q3: What thickness EPS boards are used for EWI?
A3: Common thicknesses in the UK: - 50 mm â minimal upgrade - 70â90 mm â standard retrofit - 100 mm â popular energy upgrade - 150â200 mm â low-energy / passive targets Thickness depends on U-value requirements and building regulations.
Q4: What is the thermal conductivity (Lambda) of EPS?
A5: Standard white EPS is Euroclass E (combustible). However: - It is always encapsulated within render systems. - Fire-retardant grades are used. - System fire ratings depend on the full EWI build-up. For high-rise buildings, mineral wool may be required.
Q6: How long does EPS external wall insulation last?
A6: Properly installed EPS EWI systems last 30â50 years+ with maintenance of the render finish.
