    Heat and Sound Shield

    With higher performance comes more heat and with audio upgrades comes more vibrations and sound bleed. It’s important to manage all these appropriately to get the most out of your new components. Below we explore why heat and sound shielding should be an essential step in achieving your vehicle upgrade goals.

    Heat Shield

    Heat shielding is an integral part of upgrading the performance of you vehicle. You need to get the heat of your components under control as higher performance drives up the engine temperatures and radiant heat. Higher temperatures can impede performance as well as cause issues in other areas of the vehicle if not managed properly. Heat shielding not only keeps heat within a component (e.g. exhaust system) so that the gas flows out faster, but it also protects parts like the fuel tank from radiant heat. They can come in various forms to suit different applications, wraps for headers and exhaust. to self-adhesive sheets for petrol tanks and air boxes and wraps specifically designed for the wiring in your engine bay. Finally it is important to note the heat rating (the temperature that the shielding can withstand) for both intermittent and constant heat when determining its suitability for your application

    Sound Shield

    So you’ve upgraded your sound system, but despite the 12” ported sub in the boot, two 6x9” speakers on the parcel shelf, 6” speakers in the rear doors and spilt component speakers up the front, the acoustics just aren’t right. Whether you’re getting vibrations and engine noise bleeding though into the cabin and the bass is just not thumping like you hoped, sound shielding might be just the answer.
    Sound shielding comes in different forms for different applications. Sprays and brush on provides sound deadening and protection against corrosion, dust, moisture, stone chips and abrasion and may be used under wheel arches, on underbody panels, insides of guards, quarter panels and doors, floor pans and luggage compartments. Spray on can require thinning and a suitable spray gun, but it can come in an aerosol spray can too. Sprays can also come in a foam spray which fills up cavities within panels.

    Sheets are used mainly for noise and vibration reduction and are applied to the inside of doors, boots and floors under carpet. There are specialist sheets for under bonnet as well, that resist absorption of oils, petrol, etc. these reduce passenger compartment engine and road noise levels.If you intend to use sound shielding remember it is not suitable to be used as a heat shield as well.
