5mm Premium Gold Underfloor Insulation Roll

What you'll need:

• Gold Underfloor Insulation
• High-temperature spray adhesive
• Utility knife
• Tape measure
• Degreaser + clean cloth

Tip: Install in dry, room-temperature conditions for best adhesion.

1. Prepare the Floor: Sweep / vacuum any dust and debris. Wipe the metal floor with degreaser and allow to dry fully. A clean surface is important for the adhesive to stick.

2. Roll out & Cut the Insulation: 

1. Roll the insulation out across the entire floor area. Allow it to settle flat for a moment - this makes cutting easier.

2. Roughly position it into place.

3. Cut around obstacles such as wheel arches, steps, seat mounts, or any floor reinforcements. Use a sharp utility knife and make slow, controlled cuts. Lift or fold the insulation back slightly where needed so you can see the outline clearly.

4. Check your fit frequently.
   As you cut, press the sheet down temporarily to make sure it settles nicely into floor contours.

5. Trim the edges for a snug finish.
   Once everything is sitting flat, tidy up the perimeter by trimming flush to the walls or ribs.

Tip: Large sheets can be bulky. If the piece becomes difficult to handle, don’t hesitate to cut it into two sections to make fitting easier - it won’t affect performance.

If handling large pieces feels awkward, you can also cut the insulation into smaller, more manageable sections. This makes it easier to position the material accurately, especially if installing it without any help. Smaller offcuts can also be used to neatly fill any remaining gaps.

3. Apply Adhesive & Fix the Insulation

• Work in manageable sections so the glue stays tacky.
• Spray a thin, even coat of adhesive on both the metal floor and the back of the insulation.
• Allow 30–60 seconds for the adhesive to go tacky.
• Press the insulation firmly into place.
• Smooth from one edge outward to avoid air pockets.
• Ensure it is fully stuck down over ridges and corners.

4. Add Your Flooring

• Lay plywood or your finished floor covering directly on top.
• If using wooden battens, place them on top of the insulation (not on the bare metal) to maintain continuous insulation.
