External Wall Insulation Systems

The StoTherm range of external wall insulation systems significantly reduces this energy loss by wrapping the building in a thermally resistant envelope, maximising internal space and maintaining comfortable internal temperatures all year round. And you don't need to compromise on aesthetics: Each system can be finished in a wide range of renders and architectural elements.

Sto Render Systems

The StoRend range of render systems allow you the flexibility to realise even the most demanding designs: whether flat or curved, concave or convex, white or vibrantly coloured.

By specifying Sto thin-coat synthetic renders, you avoid the problems associated with traditional cementitious renders, such as cracking and colour fading. Sto renders feature greater durability, exceptional flexibility and are through-coloured to reduce maintenance requirements.

StoRend synthetic render systems assist in overcoming many substrate issues to provide an attractive, through-coloured and long lasting render finish. System options available for a wide range of substrates, including standard masonry, substrates with poor absorbency and existing render backgrounds.

Ideal for new build and refurbishment projects - Sto synthetic renders are available in a wide selection of textures and grain sizes, and in a range of over 1,000 colours.

Rainscreen Glass Systems

StoVentec Glass can be used both as an external rainscreen cladding system, and as an internal decorative option.

The StoVentec Glass system is bespoke designed to meet the requirements of each project, from the colour and design of the glass panels through to the sub-construction that will hold it in place.

StoVentec Glass has been BBA tested and approved for all standard applications. StoVentec Glass has also received rigorous testing under extreme conditions, and has proven itself to be the safest, most robust system available on the market today.

Fire Testing

The StoVentec Glass system has undergone stringent emissions testing to ensure the system components do not release harmful fumes under intense head. The positive test results surpassed both UK and European safety requirements.

Impact Testing

StoVentec Glass is suitable for specification within high traffic areas. The system has passed all industry standard soft-body impact tests, plus hard-body impact tests in accordance with BS EN 356. StoVentec Glass currently holds the highest impact test rating of all glass rainscreen cladding systems in the UK and Europe.
