Load Spreading 60mm Polypropylene washers for Fixing and Supporting All Types of Soft to Medium Insulation Panels and Sheets - 200PCS

The product worked great.

I actually used these to to anchor down commercial grade weed barrier fabric. The U shaped anchors traditionally used for weed fabric tend to bend & buckle all too often. Using these discs coupled with landscape spikes did the trick. You can hammer them hard with a rubber mallet to pinpoint exact areas of need and they don’t break.

They do the job holding pink foam to the walls. Just don't try to tighten the screws down very far as they will pull through the center hole in the washer. Maybe if you added a secondary washer to the screw, you could recess the plastic washer into the foam better.

I used them for a little different application instead of holding insulation. I had a greenhouse and I used them for supports on the poly glass. Which day works perfect for just a little extra support

Worked well with foam insulation boards - Load Spreading 60mm Polypropylene washers for Fixing and Supporting

Used these to old foam board insulation on, plenty of surface area to hold

I used these to fasten 1 inch Owens Corning® Extruded Polystyrene Foam Board Insulation to a concrete wall. They hold the foam board tight against the concrete wall without any deformation of the foam board. I used 3/16 x 2.75 inch concrete screws. 5 stars.

These are great for holding isocyanate foam board insulation to concrete walls or foundations. I tried to use really large washers but that doesn't really work. I wish they made a smaller package as I was hesitant to buy such a big box if they weren't going to work out but they work perfectly so I will hold on to the rest for when I do larger projects insulating my basement foundation.

Used this to install rigid Styrofoam board on my house. It's very good for foam 2 inches or thicker. Used 4 1/4 screws to secure 3 inch rigid foam to joists and walls. Secures nicely and snugs it up to the drywall/framing.

Cher à première vu pour des bouts de plastique mais il s’avère que ce est bien souvent beaucoup plus cher ailleurs. En plus ce n’est pas facile à trouver en magasin physique. Vive Amazon !

Little price but good quality

Fast delivery. Well made not brittle. Should work great to attach rigid insulation to concrete with 3/16 tapcon scews
