Not as described. They put bubble wrap radiant barrier around some rockwool on the top. Not as described. The images are different than what I was shipped.

Reply from Eco-BuildingProducts.Com

Jared, Thanks for your feedback and review. The product page contains a wealth of information, including a relatively well-written description, dimensions, and images. I agree that our product description doesn't resemble your description. The recessed light cover is a cone-like cylinder measuring 14" in diameter at the base, 12" in diameter at the top, and 11.5" in height, made with TempSheild's Class A/Class1 Single Double Bubble Foil wrapped with a rockwool insulation top. The product page features two images, both of which accurately represent what is boxed and shipped. If you feel misled and unsatisfied with your purchase and the item you received, you are welcome to return it for a full refund. Let us know. Thanks

The product arrived on time and was packaged carefully. Very happy with the quality of the build as well!

Packed well, arrived quickly and installed in a cinch. My only recommendation would be to post a picture with actual dimensions of the box for the rough opening and of the outside of the trim. It would help those on a tight a schedule who have to cut the whole before the product arrives. Otherwise great overall experience. I will be purchasing more of these in the future

Tried multiple times to call into customer service to discuss product before purchase. I finally just had to order the product blind and wait to receive it to answer my questions. They did have the best price for this product.

Available in a case of 16 of the 10.1 ounce cartridges

Chemlink M-1 CR Clean Room Sealant is solvent-free, extremely low VOC, moisture curing, polyether adhesive/sealant designed for application in areas where “out gassing” and solvents are not tolerated

M-1 CR Clean Room Sealant is solvent-free, extremely low VOC, moisture curing, polyether adhesive-sealant designed for application in areas where outgassing and solvents are not tolerated. It releases virtually no molecular air contamination and contains no isocyanates.

M-1 CR will not shrink upon curing, will not discolor when exposed to UV light, and can not “out-gas” on damp surfaces as is common with urethane sealants. The product has resilient “elastomeric” properties and excellent adhesion to most construction materials.

M-1 CR is designed for environments where molecular airborne contamination can impact human health or clean room manufacturing operations and is specified for biomedical, electronic and aerospace clean rooms.
