Sound Absorption Material STP Biplast Premium 15A Armor, 15 mm, 750x1000 mm, 7.5 m2, 10 Sheets

Car Sound Absorption Mat STP Biplast Premium 15A Armor, 15 mm, 750x1000 mm, 7.5 m², 10 Sheets

Pack of 10 sheets of STP Biplast Premium 15A Armor sound absorption material — 15 mm thick polyurethane foam, 750x1000 mm per sheet (manufacturer's native size), total surface area 7.5 m². Reinforced adhesive layer, resistant to moisture and heat. Best sound absorption properties in the 250-6300 Hz frequency range. Ideal for rear wheel arches, doors, roof and boot lid — large-volume format for complete installations or multiple projects.

Complete Installations Require Large Quantities of Quality Sound Absorption Material, Without Compromising on Resistance in Demanding Areas.

A complete sound absorption treatment of the vehicle — wheel arches, doors, roof, boot lid — requires a substantial amount of material, and purchasing individual sheets for a project of this scale is inefficient both in terms of cost and stock management. STP Biplast Premium 15A Armor solves this problem with a set of 10 large-sized sheets (750x1000 mm), providing 7.5 m² of premium sound absorption material in a single pack.

The STP Biplast Premium 15A Armor Solution — 15 mm Polyurethane Foam, Large Format, 7.5 m²

STP Biplast Premium 15A Armor is a 15 mm thick sound-absorbing polyurethane foam with a reinforced adhesive layer, resistant to moisture and heat, dedicated to car sound insulation. This format contains 10 sheets in the manufacturer's native size (750x1000 mm), providing 7.5 m² — a sufficient quantity for a complete treatment or for installers working on multiple projects. An ideal choice for treating rear wheel arches, doors, roof and boot lid. Increased effective sound absorption surface, with no memory effect, plus additional thermal insulation properties. The viscous structure actively dampens vibrations in the vehicle's interior panels and eliminates rattling of plastic parts. Provides the best sound absorption properties in the 250-6300 Hz frequency range.

What you will notice immediately after application

1. Effective sound absorption in the 250-6300 Hz range — mid-frequency noises significantly reduced
2. No plastic rattling — interior panel vibrations actively dampened
3. No memory effect — the material maintains its shape and performance over time
4. Resistance to demanding conditions — reinforced adhesive suitable for wheel arches and exposed areas
5. Large format, sufficient quantity for complete treatment without repeat purchases
6. Cost efficiency — more favourable price per m² in large-volume format

STP Biplast Premium technology

Reinforced adhesive resistant to moisture and heat — Armor version

The Armor variant of the Biplast Premium adhesive layer is specially reinforced for resistance to moisture and heat, allowing application in areas where standard sound absorption materials might fail over time — such as rear wheel arches, exposed to splashes, dust and thermal variations from the braking system.

Viscous structure with no memory effect — sustained absorption in the long term

Unlike standard polyurethane foams which can lose thickness and efficiency over time, the structure of Biplast Premium 15A returns to its original shape after compression, keeping the effective absorption surface constant throughout its service life.

Why car audio installers choose the STP brand

STP (Standartplast) has been producing car sound deadening materials since 1996, and is one of the largest manufacturers in Europe. Biplast Premium range is the premium sound absorption solution in the STP range, with the Armor variant designed for areas exposed to more demanding conditions. The 10-sheet format is the choice of installers working on complete or multiple projects.
