External Wall Insulation Systems

A range of BBA-approved external wall insulation (EWI) systems and solutions that have been tried and tested for over 30 years. Our range of systems are for use on new-build or refurbishment, low- or high-rise construction and residential or non-residential developments. Facade systems increase the energy efficiency of your home, resulting in less energy consumption and more money saved on energy bills. All of our systems are available in a variety of decorative finishes, – brick effect, silicone render, dash or masonry paint – allowing you to select the most appropriate aesthetic for your construction.

K Systems range of EWI solutions

Expanded Polystyrene (EPS)

Expanded Polystyrene Insulation is an economic lightweight insulation made from Polystyrene, which is commonly used for insulation. Having a closed cell structure enables the insulation to trap air and slows down the transfer of heat towards cooler air.




Mineral Wool Insulation

K Systems Mineral Wool insulation system generates exceptional performance with a non-combustible insulation that is A1 rated.

Mineral wool insulation has excellent acoustic properties reducing the weighted sound index between 5 and 8 db and excellent environmental properties containing no gases with ODP or  GWP and also being recyclable.


Phenolic Insulation

K Systems Phenolic insulation is a fibre-free rigid thermoset phenolic core that is faced with glass tissue. Phenolic insulation is an excellent thermal conductivity (between 0.020 & 0.023 W/mK)  and facilitates more thermally efficient facades or a lower overall construction thickness. This insulation system is generally used for low rise properties which are either new build or refurbished.


Cavity Drainage Insulation

Cavity Drainage System is an external wall insulation system that is suitable for steel and timber framed buildings. The drained cavity behind the insulation ensures that any interstitial moisture escapes without detriment detriment to the performance of the system. It is available using EPS or Mineral Wool insulation with a variety of finishes available.


Ventilated Rainscreen Insulation

This is a decorative rainscreen solution designed for use with timber framed construction, incorporating a fully ventilated cavity. It can be used in conjunction with open or closed timber panels, structural insulated panels (SIPS) or light gauge steel frame.
