DCT XPS Thermal Break Strips
DCT XPS Thermal Break Strips distributed by DCTech are made from a high compressive strength 300 kPa S extruded polystyrene (XPS) rigid thermal insulation board. DCT XPS Thermal Break Strips are designed specifically to reduce the thermal loss on metal deck roof applications.
Depending upon the construction method, in some metal deck roof construction, the insulation blanket can be compressed which can reduce the thermal performance of the roof system. The use of DCT XPS Thermal Break Strips on top of each purlin above the insulation blanket will ensure that sufficient room is allowed for the insulation blanket to recover to its nominal thickness and that stated R-Values are achieved.
DCT XPS Thermal Break Strips rigid thermal insulation strips are a closed cell structure meaning that they won’t absorb moisture thus retaining their high thermal performance.
Testing has been conducted by the majority of the manufacturers of roofing systems throughout Australia and the addition of DCT XPS Thermal Break Strips will not affect the warranties of these manufacturers.
DCT XPS Thermal Break Strips are specifically designed with a high compressive strength and do not absorb moisture which tests have shown to be vital for this application.
- Metal deck roofing applications
- High compressive strength
- Long term retained R-Values
- Superior water resistant properties
- Dimensionally stable
- Will not attract vermin or insects
