The THERMO-LAG 330-660 Flexi-Blanket Thermal Barrier Material has sucessfully i

However, we believe that based on the formulation, composition and similarity of the material to the MEILMO-LAG 330-1 Subli=ing Material, that this material vill produce similar results to those of the THERMO-LAG 330-1 Subliming Material.

TSI proposes the use of a conbination of the THERMO-LAG 330-1 semi-rigid fire barrier system (pref abricated panels and preshaped conduits sections) and the TdERMO-LAG 330-660 Flexi-Blanket System, in order to provide the most cost effective usthod of instellation. The IEERNO-LAG 330-1 efficient, semi-rigid system is recommended for the vast majority of the areas to be protected, due primarily to the substantial installed cost savings of the one There are selected areas where the THERMO-LAG layered pref abricated system.

l Tieri-Blanket System would prove to be a more efficient system, such as 330-660 bare cables in bundler in areas under the sanvay.

If TSI is awarded the contract to sep;17 the THERMO-LAG 330 Fire Barrier System Materials to Millstone Units 1 and 2, we vill provida - on a no charge basis -

a Field Service Engineer for a period of one (1) week to assist the facility in i

l de:er=ining the most efficient THERMO-LAG 330 Fire Barrier System Design for l

j cach area to be vrapped and the total quantity of materials required.

TSI vill require a minimum of two (2) veeks advance written notice prior to l

dispatching its Field Service Engineer to the jobsite.
