Sundolitt releases new UK specifier support literature for XPS

Sundolitt – the UK arm of Sunde Group, Europe’s leading polystyrene products manufacturer – has launched a new set of specifier support literature aimed at helping construction and civil engineers, building contractors, architects and building materials distributors to select quickly and easily from a wide range of options of density, thickness, size and format of XPS board to suit every application. 

Sundolitt XPS is an extremely durable, thermal insulation board which is not only lightweight but is also able to withstand extreme loads. Its water resistance means it can be stored and installed in severe wet weather conditions with no risk of deterioration throughout its life. XPS is easy to cut and customise on site with no special equipment or tools required.

XPS has proven performance in a wide range of construction applications including commercial and domestic flooring, inverted roofing, cold stores and civil engineering projects such as car parks, landscaping, rail, airport and road building activities. XPS is also ideal as a large void fill where strength and durability are essential to safety, stability and longevity.

Philip Cheshire, Sundolitt’s UK General Manager said, “XPS is an outstanding product and is already well accepted by many construction and civil engineers across the UK but we wanted to make specification easier for those who may not be fully aware of its potential. We have launched a new six page overview of the credentials of the material as well as a new product data sheet which outlines all of the options available to the professional specifier as well as indicating which of the popular specifications are available ex-stock for urgent projects.”

XPS from Sundolitt comes as a rebated (ship lap) board to minimise thermal bridging as well as a butt edge board. It’s available in compressive strength/densities from 250 to 700kPa (EN826) and thicknesses from 20mm – 180mm. Other options include an embossed surface to facilitate adhesion to coatings and finishes, a tongue and groove edge and drainage lined boards with non-woven membrane. Thermal conductivity starts at 0.033W/mK to EN13164.

The new specifier literature also stresses the strong environmental credentials of Sundolitt XPS which – being 100% CO2 blown - uses no harmful greenhouse gases during manufacture. The material can be recycled when recovered at the end of its life. The company also states that with the built-environment accounting for 40% of Europe’s energy consumption, the greater energy efficiency that comes from using products such as Sundolitt XPS can, in some cases, reduce total energy consumption in buildings and structures by 75%. 

The new specifier literature is available by contacting Sundolitt’s UK expert team who can also help and advise architects and specifiers on the most appropriate specification for their needs.
