Sound Deadening & Insulation

A quieter, cooler cabin changes the way you drive. Road roar, panel vibration, engine drone and the beating Australian sun all add fatigue to every trip, whether you are touring outback highways in a four-wheel drive or commuting in the city. Our sound deadening and insulation collection brings together butyl deadener mats, thermal foam, radiant barriers, weather seals and heat-blocking covers and sunshades, giving you the materials to hush the noise, tame the heat and make your vehicle a more comfortable place to be.

Butyl Sound Deadener for Doors, Floors and Boot

The heart of any noise project is self-adhesive butyl deadener, which adds mass to thin metal panels so they vibrate less and drum out less road noise. Weisshorn butyl mats come in convenient 32cm by 50cm sheets in 12, 24 and 36 piece packs, and several kits include an application roller to press the material firmly into place. If you prefer coverage measured by area, butyl mats are also offered in thicknesses such as 50 mil across 4.8 square metres, 80 mil across 3.3 square metres and a heavier 200 mil across 2.3 square metres, letting you match the grade to doors, floors, the boot or wheel arches. These heat-proof, self-adhesive sheets are the proven first layer for a serious sound treatment.

Thermal Foam and Radiant Barriers

Once vibration is under control, a second layer manages heat and higher-frequency noise. Closed-cell foam such as the 10mm heat-proof noise proofing sheet absorbs sound and insulates against engine and exhaust warmth, while a dedicated 12-piece engine bay and bonnet foam kit tackles noise and heat right at the source. For radiant heat from the sun and road, a double reflective insulation roll with a foam core and radiant barrier, measuring 120 by 48 inches, helps keep floors and firewalls cooler. Layering butyl, foam and reflective barrier is the classic approach used with brands like Dynamat and Car Builders, and the compatible application roller in this range helps you get a strong bond every time.

Seals and Weather Strips

Air gaps let noise, dust and heat straight in, so quality seals make a real difference. Self-adhesive D-profile rubber weather strip in 6 metre lengths and 19mm by 2 metre window seal strips close gaps around doors, windows and sunroofs to reduce wind noise and improve insulation. They are simple to fit, trim to length with scissors and press into place, and suit a wide range of makes and models. Fresh seals also help keep the cabin cleaner and can cut down on rattles and whistles at highway speed.

Sunshades and Protective Covers

Managing heat before it enters the cabin is just as important in Australia. Foldable windshield sunshades and reflective visors block UV rays and keep dashboards and seats cooler when parked, with baby and child side window shades protecting young passengers. Winter and all-season windshield covers, including magnetic and door-handle styles in sizes up to 230 by 148cm, guard against frost, ice, dust and sun, while side mirror covers add anti-frost protection. Full vehicle and motorcycle covers in durable 210D and 190T Oxford fabric shield your ride from the elements during longer storage.

Planning and Installation

For best results, clean and dry each panel before applying butyl, then roll firmly to remove air pockets and lock in the adhesive. Start with the doors and floor for the biggest gain, add foam and reflective barrier where heat is an issue, and finish with seals to close the gaps. Estimate the square metres you need by measuring the surfaces you plan to cover, and keep an application roller on hand for a clean, lasting bond.

Sound Deadening & Insulation — FAQ

How much sound deadening material do I need for my project?

It depends on the area you want to treat; our butyl mats come in multi-sheet packs and roll sizes covering different square-metre amounts, listed in each product. For doors alone a smaller 12 or 24-piece pack often does the job, while full-floor or boot treatments call for larger packs or coverage rolls. Measure your panels first, then choose a pack that comfortably covers the surface with a little to spare.

What is the difference between butyl deadener and foam insulation?

Butyl self-adhesive mats add mass to panels to reduce vibration, rattles and road drumming, making them ideal for doors, floors and boots. Closed-cell foam and reflective insulation target heat and higher-frequency noise, and suit areas like the engine bay bonnet and firewall. Many builders use butyl first for vibration control, then add a foam layer over the top for heat and noise.

How do I install self-adhesive sound deadener?

Clean and dry the panel thoroughly so the adhesive bonds well, then cut the mat to size, peel the backing and press it firmly into place. Rolling the sheet with an application roller, like the ones we stock, works out air pockets and helps the butyl key onto the metal. Work in overlapping sections and press the edges down well for the best long-term hold.

Will these products help with heat as well as noise?

Yes, our butyl mats and foam products are designed to reduce both vibration noise and heat transfer, which is why they suit floors, firewalls and engine bays. Reflective insulation rolls add a radiant barrier that helps keep cabin temperatures more comfortable. Combining a mass layer with a foam or reflective layer gives you the most effect against both heat and sound.

Do you stock door and window seals to cut wind and outside noise?

Yes, alongside deadening mats we carry self-adhesive rubber weather strips and D-profile seals in various lengths to close gaps around doors, windows and sunroofs. Sealing these gaps helps reduce wind whistle, dust and outside noise entering the cabin. Clean the surface before applying, then press the strip firmly along the edge so it forms a consistent seal.
