Licata Therm Mineral Wool External Wall Insulation (EWI) Steel/ Timber Frame system - External Wall Insulation System
Verified by manufacturer 2 months ago
External Wall Insulation System on steel or timber frame substrates with mineral wool insulation with a choice of acrylic or clay brick slips, or a coloured render for the decorative finish.
Application
Suitable for both new builds and refurbishment.
Description
The Licatatherm mineral wool EWI system has increased strength and crack resistance, due to the glass fibre mesh. Breathable and fully fire compliant, it’s suitable for both new builds and refurbishment. Choose from brick slips or a coloured render for the decorative finish. EWI systems help improve the appearance and thermal efficiency of properties, reducing overall energy consumption.
Features and benefits:
- Suitable for various substrates.
- Over 700 colour options.
- Weather resistant.
- Energy carbon saving.
- Breathable.
- Protects against algae and mould.
- Fully fire compliant.
Durability:
- This system has an assessed anticipated lifespan in excess of thirty years.
Design considerations:
- Should the proposed project incorporate any unique design elements or curved elevations, please contact the manufacturer for recommendations or assistance.
INSTALLATION
Installer:
The system manufacturer, or a contractor approved by the system manufacturer. Installation shall be made strictly in accordance with Licata Building Systems Ltd instructions. Reference should be made to the project specification, method statement, drawings and all other relevant literature. Consult with LBS Ltd for latest literature and technical bulletins.
FINISHES
Primer:
- Apply the Isolante LG Primer with a roller or brush to the dry base coat in an even pattern. Where possible always use the colour Primer to match the specified Topcoat finish. Allow to dry for a minimum of 12 hours.
Licata Silicone Render:
- Thin coat is a ready mixed top coat for external use, highly breathable, high water resistance and excellent mechanical strength. Silicone render provides a high resistance to algae, fungi, mould and to atmospheric agents. The careful choice of acrylic binders and silicone, ensures good durability and a gloss finish with pearlescent effect to the water drops.
- Licata Silicone Render is suitable as a decorative finish in all work requiring high permeability to water vapour.
Siloxan Color:
A coating made with water-dispersed siloxane binder paste, ready for use and which can be pigmented. Siloxan Color is specifically designed for work on new or existing facades, as well as for the decorative phase of reinforced skim coating, and in LicataTherm external solid insulation. Owing to its formula, Siloxan Color provides complete protection for the facade against rain and atmospheric agents. The special additives contained in the formula guarantees excellent protection against algal and mould growth.
Brick slips:
The brick slip systems can be used across a range of different applications and substrates. Suitable for internal and external application on both new build or refurbishment projects. The brick slip systems are durable and weather-resistant with a 10-year guarantee if installed by a Licata approved applicator. A choice of acrylic or clay brick slips are available.
- Acrylic Brick Slips: provide the traditional appearance of a brick finished building but with technology of a lightweight acrylic or mineral brick slip finish. Acrylic Brick Slips are a suitable finish for external wall insulation systems used on new build or renovation of old buildings. It can also be used with timber-metal frame or modular where speed and weight are important in designs but traditional brick slips would not be recommended.
- Licata Clay Slips: are a versatile thin brick cladding that simulates the look of traditional clay brickwork whilst providing greater insulation and more flexibility of style and application.
