When summer hits, car interiors can turn into ovens. In winter, the opposite happens, heat escapes, and you’re left with cold seats and foggy windows. For years, automotive enthusiasts have been looking for ways to keep cabin temperatures stable all year round while also reducing road noise.
Let’s explore the best ways to insulate your vehicle and how B-Quiet HLiner makes it easier than ever to stay cool, quiet, and comfortable.
Common Materials Used for Vehicle Insulation
Many people try to insulate their vehicles using whatever they have on hand, from old-school jute mats to Home Depot insulation meant for houses. While these might seem like quick fixes, they come with major downsides:
- Jute mats are loosely woven fabrics that absorb heat and moisture. Over time, they trap water against the metal body, leading to corrosion.
- Metal heat shields, made from aluminum or steel, can reflect some heat but offer little to no sound-deadening performance. They also rust, rattle, and often detach over time.
That’s why professional installers and DIY enthusiasts are turning to automotive-specific insulation materials designed for both thermal and acoustic performance.
What should I use to insulate my vehicle?

There are a lot of products that are used to reduce heat in your car, automotive manufacturers use a product sometimes called jute which is simply woven fabrics loosely piled together to form a matting, although effective it tends to absorb the heat and get heat soaked and is prone to hold in water when it gets wet, resulting in water, touching the metal surface below.
Heat shield, either made from Aluminum, or steel are also used, however after a while, they tend to rust, fall off and do not offer much sound deadening qualities.
B-Quiet Sound Deadening has found that the best answer to reducing in car temperatures either from exhausts close to the floorboard or the heat from the sun is B-Quiet Hliner.

Road noises usually cause irritation and fatigue, making the radio, music, and conversations unclear and distorted. HLiner insulation foam improves sound quality by a long shot with the elimination of road noise, engine noise, and rattling from panels or car parts.
The best part is how easy the insulation is to install
Just measure the desired length, cut, and fix it under the hood, wall, or ceiling. The flexible foam and foil outer layer can fit any shape, curve, or surface with ease, and can be put up to 8 inches from heat sources like the engine, transmission, furnace, and exhaust to keep the heat out in the summer and keep it in, during the winter.

Perfect for Cars, Trucks, and Camper Vans
In cars and trucks, HLiner keeps the cabin cool in traffic, reduces engine noise, and improves audio quality.
In camper vans, it’s ideal for insulating walls, floors, and ceilings, helping keep the van cool in summer and warm during chilly nights.
