    Product detailed description

    🏠 EXTERIOR THERMAL INSULATION COATING

    Imagine buildings that reflect heat away in summer and keep warmth inside in winter without major renovations. THERMISEAL EXTERIER is a thermoactive and thermal-insulating coating compound with aerogel technology – it limits overheating in summer and heat loss in winter.

    Proven on façades = year-round energy savings – suitable for concrete structures, metal surfaces and wooden materials. On hot days it reflects solar radiation away; in winter it helps prevent heat from escaping from the building. Ideal for façades, balconies, loggias and all exterior building surfaces.

    ⚡ RESULT: A cooler interior in summer, warmer in winter, and significant savings on heating and air conditioning.

    Thermiseal Exterior - thermoactive coating for façades

    🌌 WHAT YOU MAY BE EXPERIENCING RIGHT NOW

    We know you may be dealing with buildings overheating in summer and high heating costs in winter. Perhaps you struggle with a hot façade that heats up in the sun, or cold walls through which heat escapes in winter. You may dread every hot day, every freezing winter, and astronomical energy bills.

    THERMISEAL EXTERIER is designed exactly for these situations. It addresses problems quickly and effectively with aerogel technology. Applying the coating creates a layer that reflects heat away in summer and helps prevent heat from escaping from the building in winter. It is not just a paint – it is year-round protection against energy loss.

    Thermiseal Exterior - principle of the thermoactive coating

    🎯 WHY CHOOSE THERMISEAL EXTERIER

    While ordinary façade paints heat up in summer and let heat escape in winter, THERMISEAL EXTERIER with aerogel technology works all year round – reflecting heat away in summer and keeping warmth inside in winter.

    What you can expect:
    ✅ Reflects heat away in summer – the façade does not overheat even in extreme heat
    ✅ Keeps warmth inside in winter – helps prevent heat from escaping from the building
    ✅ Year-round energy savings – less heating and air conditioning
    ✅ Aerogel technology – the world’s most effective insulating material
    ✅ Application thickness of 0.8–1.0 mm – maximum effect, minimal thickness
    ✅ Limits overheating and heat loss – protects structures all year round
    ✅ Hydrophobic and vapour-permeable – moisture resistance
    ✅ Minimum service life of 15 years – when the application technology is followed

    🌡️ MAIN BENEFIT: Instead of an overheated façade in summer and cold walls in winter, you get optimal thermal comfort all year round!

    AEROGEL - structure of Thermiseal technology

    ing. Miroslav VALÁŠEK, developer of the THERMISEAL concept

    “We use THERMISEAL EXTERIER for year-round energy-saving projects. Aerogel technology in a thin 0.8–1.0 mm layer can reflect solar radiation away in summer and help prevent heat from escaping from the building in winter. It works like an intelligent barrier. The result: significant savings on heating and air conditioning. Tip: The greatest effect is on south- and west-facing façades – where temperature fluctuations are the highest.”

    Miroslav Valášek

    ✨ HOW THERMISEAL EXTERIER WORKS

    THERMISEAL EXTERIER is a thermoactive and thermal-insulating coating compound based on a water-dilutable filler enriched with aerogel technology. An application thickness of 0.8–1.0 mm creates a surface layer that regulates heat flows all year round.

    🔬 How year-round thermal protection works

    1. Thermal reflection in summer: Special components reflect solar radiation back into the atmosphere. The façade does not overheat even in extreme heat – instead of a scorching wall, you have a cool surface.

    2. Thermal insulation in winter: Aerogel technology helps prevent heat from escaping from the building. It keeps warmth inside and reduces heating costs – working like an invisible insulation layer.

    3. Intelligent barrier: It responds to temperature conditions – protecting against heat in summer and cold in winter. It helps eliminate thermal shocks and protects structures all year round.

    🖌️ TWO APPLICATION METHODS

    1. APPLICATION WITH A STAINLESS-STEEL TROWEL:
    • Use a stainless-steel trowel with 6 mm teeth
    • Apply with the notched side, then smooth with the flat side
    • Suitable for smaller areas and details
    • Absorbent substrates must be primed

    2. STŘÍKÁNÍ:
    • Naředte do konzistence umožňující rovnoměrné stékání
    • Použití nízkotlakých i vysokotlakých stříkacích zařízení
    • Rychlá aplikace na velké fasádní plochy
    • Ideální pro celé budovy a bytové domy

    💡 Pro tip: The greatest effect is achieved on south- and west-facing façades – where temperature fluctuations are the highest!

    ⚠️ IMPORTANT NOTICES

    For maximum year-round thermal protection, follow these guidelines:

    🚫 DO NOT APPLY TO:

    • Permanently damp substrates – rising damp or damaged waterproofing
    • Unsound old coatings – always remove unsound layers
    • Contaminated surfaces – must be free of grease, dust and dirt
    • Frozen substrates – apply only at temperatures above +5°C

    ⚠️ PAY ATTENTION DURING APPLICATION:

    Correct application is essential for year-round thermal protection:

    • Application thickness 0,8-1,0 mm – pro optimální termoreflexní i izolační účinek
    • Kovové podklady natřete základovou barvou – lepší přilnavost
    • Savé podklady penetrujte – dřevo, sádrokarton, beton
    • Nesavé podklady ošetřete adhezním můstkem – plastové povrchy

    ✅ IMPORTANT TIPS FOR MAXIMUM YEAR-ROUND PROTECTION:

    • Start with the south- and west-facing façades – where temperature fluctuations are highest
    • Apply over the entire surface – partial application reduces the year-round effect
    • Mix to a thick cream consistency – gradually add clean water
    • Apply at temperatures from +5°C to +25°C – optimal conditions
    • Protect from rain during drying – for at least 24 hours
    • Tinting is not recommended – it may reduce thermal-reflective properties

    ❓ Frequently Asked Questions:

    ❓ How does THERMISEAL EXTERIER work all year round? >
    V létě odráží sluneční záření zpět do atmosféry a zabraňuje prohřívání fasády. V zimě aerogel technology blokuje únik tepla z budovy. Funguje jako inteligentní bariéra – automaticky reaguje na teplotní podmínky.
    ❓ What are the year-round energy savings? >
    THERMISEAL EXTERIER significantly reduces heating and air-conditioning costs. In summer it keeps the façade cool, and in winter it helps prevent heat loss. Year-round energy savings thanks to aerogel technology.
    ❓ Does it work in extreme temperatures? >
    Ano! THERMISEAL EXTERIER je navržen pro extrémní podmínky – od -20°C do +80°C. Aerogel technology a termoreflexní vlastnosti fungují spolehlivě v létě i v zimě.
    ❓ Where is the year-round effect greatest? >
    The greatest effect is on south- and west-facing façades – where temperature fluctuations are highest. Also ideal for flat roofs, balconies and loggias exposed to weather.
    ❓ Co je aerogel technology? >
    Aerogel is the world’s most effective insulating material, with exceptionally low thermal conductivity. In THERMISEAL EXTERIER it provides maximum year-round thermal protection in a minimal layer thickness.
    ❓ Will it solve moisture problems? >
    Yes! The hydrophobic yet vapour-permeable structure repels water while allowing water vapour to pass through. It helps eliminate moisture condensation caused by temperature differences in summer and winter.
    ❓ How long does the year-round protection last? >
    THERMISEAL EXTERIER má minimální životnost 15 let při dodržení technologie aplikace. UV resistance zajišťuje dlouhodobou stabilitu termoreflexních i izolačních vlastností.
    ❓ Can I overcoat it with paint? >
    Yes, but tinting is not recommended – it may reduce thermal-reflective properties. THERMISEAL EXTERIER can be overcoated with façade paints after consultation with the supplier.
    ❓ Is it enough to apply it to only part of the façade? >
    For maximum year-round effect, we recommend applying it over the entire surface. Partial application will reduce the effect. Start with the south- and west-facing façades – where temperature fluctuations are highest.
    ❓ How much THERMISEAL EXTERIER do I need? >
    Spotřeba: cca 1 litr/m² aplikované plochy. Pro jižní fasádu RD 10×8 m potřebujete 80 litrů. Packaging 5L, 12L, 30L pro různé velikosti projektů.
