Outdoor products: durable and weatherproof solid surface material for architectural challenges

For many years now, spectacular architectural façades and exterior wall-claddings have been made from HI-MACS® all over the world. Iconic architecture has come to life and in doing so, the advantages are often skilfully crafted: Durable surfaces for public building, commercial spaces and private homes, relief milling with writing, surfaces with company logos, combined with spectacular light effects and curvy designs. And every good design inspires even greater projects.
LG Hausys is expanding exterior possibilities with a new and outdoor dedicated product family: HI-MACS Exteria®.

The product category includes HI-MACS®-FR; which has offered increased fire resistance for many years – the first solid surface formulation to receive the ETA certification for public building facades.
Also, a new advanced formulation is available for façades, HI-MACS® S828, offering better UV resistance, which is particularly important when the façade is exposed to high levels of sunlight.

Thanks to this new formulation, HI-MACS® has obtained the French QB certification and CSTB (Centre Scientifique et Technique du Bâtiment) ATec “Avis Technique” for facade applications, earning recognition for its outstanding quality.

HI-MACS® Sheets

The perfect basis for your ideas: our comprehensive range of sheets.

HI-MACS® is available in different thicknesses, formats and sizes. Perfect for maximum cutting and minimal costs.

HI-MACS® dimensions, thicknesses and special formulations available.

Size matters – to increase efficiency and reduce offcuts
HI-MACS® can be supplied in different sheet thicknesses, formats and sizes. Ideal for maximum cutting, minimum wastage and minimal costs. However, not all colours are available in any thickness, please see the colour charts here opposite for exact availability.
HI-MACS® FR - Low flammability
The fireresistant FR version is available in S728 Alpine White and complies with the requirements of the IMO standard modules B + D and M1. This quality is particularly suitable for use in public buildings, façades and shipbuilding.
HI-MACS® Ultra-Thermoforming:
This special formulation can be formed into very small radii (up to 6 mm radius).

Properties and sealing

A living material for shimmering facades

A living material

HI-MACS® has natural contraction and expansion properties related to temperature changes. When HI-MACS® is applied outdoors, thermal expansion is 30 x10-6 m/°C. A suitable fixing system must therefore be selected.

To build the HI-MACS® façades, LG Hausys suggests using a structure made from aluminium sheeting and a ventilated façade system using BWM fixings.

What about seals?

HI-MACS® does not recommend using glue on the outer facade because of expansion. We suggest leaving gaps of 8 to 10 mm between each panel.

Our guarantees

HI-MACS® offers a 10 years warranty on colours' UV resistance and loss of gloss over 40%, 10 years on colour leaching and 20 years on colour peeling, swelling or delaminating. The warranty is applicable after the first installation and is only valid for the sheet material; adhesives are excluded. The conditions for this warranty are based on pratical experience and on-going tests.
