Why This Sealing Solution Is Perfect for You
✔ Helps keep water and drafts out: The silicone D-profile closes gaps and joints to help keep water and air out. Its flexible, rot-resistant material stays flexible even with constant exposure to moisture, helping prevent moisture damage.
✔ Installs without tools or glue: Peel off the backing liner and press the self-adhesive strip into place. No separate glue, tools, or specialist knowledge is needed for installation.
