CLST®: The strong, sustainable, alternative to Gen 1 mass timber.
USA 2022
CLST® has successfully completed testing, and was analysed by Northland Engineers who provided their report stating outstanding performance results.
See this PDF file for all the details.
CLST® from Aspen has been independently proven to be up to 3 times stronger in the major axis and up to 5 times stronger in the minor axis than commercially available CLT in the U.S.
Laminae used in CLST® are treated holistically for termite, moisture, fungal and fire resistance, unlike the envelope treatment of planks used in CLT.
Lignor’s Aspen CLST® has been proven to have far lower risk of delamination in fire, unlike conventional CLT which can produce chimney effects which further fuel fires.
CLST® has superior fastener performance and holding strength when compared to conventional softwood CLT.
It is strong and lightweight, with high ductility which makes it ideal for building in earthquake zones.
Unlike LVL and plywood, it can be sawn, routed, profiled, turned, milled, nailed or screwed in any plane.
It is available in thick and thin formats.
Thin CLST®
Made with laminae thinner than 16mm has multiple applications in the transport sector, in commercial and industrial construction and for use in domestic housing as an alternative to OSB. and plywood.
Suitability:
Truck, railway wagon and bus floors
Container floors
Industrial flooring
Roofing and flooring panels/cassettes in domestic housing
Concrete shuttering boards
An alternative to plywood
An alternative to LVL
Lignor CLST® 3 layer E-nitens South America MOE C-1.27-E
Thick CLST®
Thick CLST® with laminae thicker than 16 mm is designed to be a lower cost and better performing alternative to CLT, for use in mass panels in large structures and concrete slabs.
Suitability:
Construction of domestic housing, multi-storey apartment and industrial buildings, and warehouses.
Self-supporting roofing and flooring panels
Low-cost housing supplied in “flat pack” form
Posts and beams cut to order from large billets
Lignor CLST® Thick. 3 Laminae total 132mm thickness.
“Preventing deforestation is potentially one of the simplest ways to reduce global emissions. At the moment, carbon emissions from deforestation account for some 18% of global greenhouse-gas emissions, more than all the world’s trains, cars, lorries, aeroplanes and ships combined.”

ESL®
ESL® or eucalyptus-based Engineered Strand Lumber has up to twice the stiffness of softwood and performs exactly the same as sawn timber.
Suitability:
Posts and beams cut to order from large billets
Industrial flooring
Manufacture of CLST™
LST®
LST® or Laminated Strand Timber (LST®) is made by laminating layers longitudinally to make beam members larger than the original press.
Suitability:
Posts and beams
Buildings requiring longer spans
