Glazing contractors who switched, in their own words. We will put you in touch with any of them before you place a first order.

We have been using this silicone for over ten years for windows, doors and shower doors. We have not seen a difference from the silicone we used before. The price is simply more budget friendly.
Muha CorpOn the silicone sealant

“

The soft rod is what sold us. Our joints are never the same width twice on a retrofit, and this one squeezes in and stays put without bubbling the bead. We stopped carrying two diameters because one now covers the range.
Alex Glass CorpOn the backer rod

“

Every shim in the pack is the same thickness, which sounds like a small thing until you are shimming a long run of storefront. Nothing crushes out under load and the crew stopped double-checking gauges.

01 / Stock

We do not sell what we cannot ship.

Availability on this site means the material is in the building. One missed promise costs more than a year of advertising.

02 / One order

The whole joint, one invoice.

Sealant, rod, shims and fasteners arrive together. No chasing four vendors for one detail, and no partial deliveries holding up a crew.

03 / Proof

Test it before you switch.

We send a sample and the full four page laboratory report. Run it on your own detail. If it does not hold, do not buy it.

Every inspection item: pass.

Laboratory results on the neutral cure silicone. The full report, the TDS and the SDS go out on request.
