Renovation plaster (white) for filling vapor-permeable and frost- and waterproof renovation plasters, for interior and exterior use.
EKOR 41 R plaster is designed for thin-layer filling of renovation plasters:
EKOR 44R,
EKOR 44RM,
INTONACO WTA,
ANTOL RISAN ONE.
EKOR 41 R (renovation) mortar is a dry mixture of cement, silica and lime aggregates, modified synthetic resins, and air-entraining admixtures. After mixing with water, it is easy and convenient to use. It has excellent adhesion to the substrate, allowing for easy filling in any direction.
The product is characterized by hydrophobicity, porosity, and diffusion, compatible with vapor-permeable and renovation plasters.

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.
