Application

  • Suitable for new build and refurbishment applications.
  • For brick, blockwork, steel frame and timber frame substrates.

Description

The Licatatherm K5 EWI system benefits from being breathable, weather-resistant and fully fire compliant. With increased strength and crack resistance, due to the glass fibre mesh. It also helps protect against algae and mould. Choose from brick slips, coloured render or resin multi-colour 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.
  • Protects against algae and mould.
  • Energy carbon saving.
  • Breathable.
  • Fully fire compliant. 


Durability:



  • This system has an assessed anticipated lifespan in excess of thirty years.


Movement joints:



  • Where movement joints are present in the existing substrate, it is highly recommended that they are carried through the system. Please consult with the manufacturer for further details on where movement joints are required.


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 is 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 Brickslips 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.

Manufacturer guidance

Designed and tested to meet the current wind load and suction requirements, the system is adhesively fixed with supplementary fixings in accordance with BS EN 1991-1-4:2005. Special consideration should be given to locations with high wind-load pressure coefficients, as additional fixings may be necessary. It is recommended that a load factor of 1.5 is used to determine the ultimate wind load, in accordance with BS EN 1990:2002.
