FAQS

Frequently Asked Questions

Common technical queries regarding the selection and installation of our rubber plug caps.

What material are these plugs made from?

They are primarily made from high-quality EPDM or silicone rubber, chosen for their excellent aging resistance in outdoor environments.

Are these plugs waterproof?

Yes, when sized correctly for the hole, they create a tight seal that prevents water penetration into the curtain wall cavity.

Can I get a custom color to match my facade?

Yes, we can produce custom colors based on RAL or Pantone references for bulk orders.

How do I determine the correct size?

The plug size should match the inner diameter of the hole. We recommend a slightly oversized plug for a secure friction fit.

Do these plugs require adhesive for installation?

No, they are designed for press-fit installation, though silicone sealant can be added for high-pressure sealing requirements.
