BASE ACOUSTIC SOUND LINE 5 Acoustic Foam, 5mm, Sheet 750 × 1000 mm

Description

BASE ACOUSTIC SOUND LINE 5 — self-adhesive acoustic foam Ultimate with a thickness of 5 mm, sheet 750 × 1000 mm (0.75 m²), includes 1 sheet; universal product — the sheet is cut to fit a part for any car. It is glued under plastic interior trim, door cards and the trunk, on joints and into speaker enclosures — where there is little space for a thicker layer; it absorbs sound but does not damp metal vibration. It differs from SOUND WAVE 15 by thickness (5 mm vs 15 mm) and a smooth front surface without texture.

Where is 5 mm foam useful?

The main advantage of 5 mm thickness is that the sheet fits where there is little space under the trim and a thicker material would prevent the part from seating properly. That’s why this foam is chosen when you need to:

• apply it to the back side of plastic trim panels in the cabin, door cards and the trunk — the thin layer fills the gap between plastic and the body, so panels and clips rattle less;
• cover individual joints and mounting points — the sheet is easy to cut into narrow strips of the required shape with a regular knife or scissors;
• refine speaker enclosures and DIY acoustic structures to remove unwanted resonances inside.

How to combine foam with other soundproofing layers?

Sound insulation is done in layers. First, vibration damping is applied to clean metal and rolled down with a soundproofing roller. Acoustic foam is laid as the second layer — over the vibration damping or on the inner side of the trim panel. For places where plastic parts rub against each other, there are separate materials in the anti-squeak section. This is the general sequence: the exact set of layers depends on the area you are treating and on how much space there is under the specific trim piece.

What are the characteristics of SOUND LINE 5?

• Thickness — 5 mm.
• Sheet size — 750 × 1000 mm, i.e., 0.75 m² of material.
• Installation type — self-adhesive, no additional glue required.
• Package contents — 1 sheet.
• Product type — universal: the shape is cut on site to fit the part.
• Manufacturer — Ultimate.

How many sheets are needed and how to stick it on?

There are no ready-made “for the whole car” kits: the material is sold in sheets, and each part is treated separately. One sheet covers 0.75 m². Measure the area of the trim panels you plan to treat, divide by 0.75, and add extra for trimming along the contour — panels have cutouts for handles, speakers and fasteners.

Before installation, the surface is cleaned of dust, degreased and allowed to dry. The release liner is removed gradually, pressing the sheet down by hand right away so it lays flat without bubbles, and then it is rolled down with a roller for tight contact over the entire area. Before reassembly, make sure the foam does not block the trim clips and retainers.

What other materials are available for a quieter cabin?

If you need a thicker layer with a textured surface, the BASE ACOUSTIC range includes SOUND WAVE 15 — 15 mm foam in a sheet of the same size. Among 75 × 100 cm sheets with a thickness of 5 mm, the catalog also includes the sound-absorbing sheet ULTIMATE SQL 5 mm, its laminated version, and the sealing material Sound Absorber 5 mm. The full assortment is collected in the sound insulation, thermal insulation and car noise and vibration insulation sections.
