Welcome to Dritherm International Inc. makers of DriTherm™ and DriWrap™ high performance hydrophobic insulations for above and below grade applications.

DriTherm™ Pour-in-Place Underground Insulation

DriTherm™ is a field applied hydrophobic powder type insulation and corrosion protection product designed for below grade applications. First

brought to market in 1967 as Protexulate, DriTherm™ remains one of the most cost effective and environmentally friendly methods of insulating

underground thermal systems. Our self-compacting product insulates and protects all types of thermal systems from -273°F up to 480°F.

DriWrap™ Hydrophobic Blanket Insulation

DriWrap™ is a revolutionary hydrophobic aerogel type insulation and corrosion protection blanket designed for demanding applications. DriWrap™

is a super insulation with low thermal conductivity, low water absorption, and high strength. Corrosion under insulation (CUI) is reduced by creating

a water resistant/vapor breathable barrier which allows moisture to evaporate away. Applications include thermal piping and tanks in above and

below grade applications from -273°F up to 1250°F.
