A new insulation product with significantly improved thermal resistance as compared to conventional insulation products. Its thin profile, superb flexibility, and compression resistance allow for thermal protection in hard to insulate spaces. It can be easily cut and conformed to complex shapes and tight curvatures and adhered without difficulty to building products. An ideal solution for sealing tough connection points in building envelopes, such as where glazing systems meet cavity walls, where below grade systems meet above grade systems, and where parapets meet roofs. Building Insulation Blanket is also fire-resistant, hydrophobic and does not settle over time.
DOWSIL™ HPI-1000 Building Insulation Blanket is a thin, flexible insulation material that uses advanced silicon-based aerogel technology to deliver significantly improved thermal resistance versus conventional insulation products.
The thin profile allows for fast, easy installation compared to conventional insulation materials and provides excellent thermal bridging for difficult profiles such as curves and corners where it’s often bulky or complicated to install. This material is fire-resistant, water-vapor permeable, and hydrophobic.
DOWSIL HPI-1000 Building Insulation Blanket is an ideal solution for insulating challenging space-limited and transition conditions in building envelopes, such as:
Using thermal modeling software, DOWSIL HPI-1000 Building Insulation Blanket was evaluated and analyzed based on ASHRAE 1365-RP.

To check pricing and availability of a product, first consider which buying option is right for you if both the "Buy Direct" and "Find a Distributor" options are offered.
Currently buy directly from us? Just get in touch with your procurement team, who will work directly with us to clarify price options and availability for you.
Already work directly with our sales contact? Simply check with them for pricing and availability. Lead times may be longer than if you go through an available authorized distributor. For large-scale, ongoing needs, we'll work with you to establish a reliable and timely supply.
New to Dow Consumer Solutions? If distribution is an option for a product, we suggest starting there for the fastest confirmation of price and availability. This will also save you time compared to setting up a new buying account directly with us. If you have questions, please feel free to discuss options directly with our service team.
When authorized distributors are offered as a choice, they are typically the fastest route to clarifying price and may also offer shorter product lead times. We take time to select, train and support best-in-class distributors—and they're a great option for you if any of the following apply:
