I want to apply some standardplast products over my car to improve heat insulation and sound proofing.

After spending some time understanding the different products, these are the best products on my opinion.
Why STP
Although they are more brands in the market, STP are easy to get:
- They are in many countries.
- They have YouTube channels in different languages explaining how to install them.
- The product, overall, is very good.
Products
- STP Black Silver: 1.8mm vibration damping and sound proofing.
- STP Black Gold: silver but 2.3mm.
- STP Aero: It’s Aero gold, but expensive, not worth it.
- STP Accent: 6mm/10mm heat insoluation & vibration dumping
- STP NoiseBlock: 2mm sound insulation.
Installation
It’s expected combine different products for getting better overall performance.
A commonn combination in layers is: aero silver/gold + aero accent + noise block.
There is a complete instructions section in the website.
Aerocell QP

There is a new lineup of products claiming to combine a sandwich in line layer (15 in 1), reducing the cost.
There are two options:
- Genio: 6mm for interior floor, interior doors or front wheel arches.
- Intrigo: 4mm for roof, hood, trunk, exerior doors, etc.
According with a distributor, it’s better than combine Aero + Accent.
