Description

The right staples make all the difference. 🔩🛠️

When you're installing underfloor insulation into timber joists, you want fasteners that are strong, reliable, and built to last. That’s why we recommend Arrow T50 Staples: high-performance, galvanised staples specifically suited for insulation installs. They offer excellent grip, resist rust, and won’t tear through the insulation batts.

These staples are contractor-grade and compatible with most T50 staple guns (including the one in our Easy Install Kit). They’re perfectly sized to pierce the insulation backing and anchor cleanly into timber joists, giving you a secure hold that stands the test of time—especially in underfloor environments where humidity can be a factor.

✅ Ideal for securing insulation batts to timber floor joists

Galvanised for corrosion resistance and durability

✅ Compatible with standard T50 staple guns

✅ Provides a firm, clean hold without damaging the insulation

✅ Used and trusted by professional retrofit installers across Australia

Secure your insulation the right way—first time, every time.

For a smooth, sturdy and long-lasting install, Arrow T50 Staples are your go-to.

FAQ

Q: Can Arrow staples be used for underfloor insulation installation?
A: Yes, Arrow staples are the best staples to use for underfloor insulation installation. They are robust, reliable, and provide a secure fastening for polyester insulation. 

Q: Can I use staples to secure fibreglass / earthwool / pink batts under my floor?
A: No. Fibreglass including the brand names earthwood and pink batts cannot be secured using staples. Fibreglass insulation is made from spun glass splinters which are brittle and break when stapling is attempted. Polyester insulation can be very securely stapled into place for the long term with staples.
