Our Stage 1 Sound Deadener is the first layer you need to apply when sound deadening a car. We then have carpet underlays and other foam insulation that you can apply over the top to block sound and help insulate cold and heat.
Is your Sound Deadener bitumen?
No, the adhesive product is butyl based. This has an advantage over the bitumen, which dries out, cracks and lifts allowing water to get underneath it and cause rust. The butyl is a waterproof material ensuring that water cannot get between the Sound Deadener and the panel. Bitumen also has a strong odour, which the Sound Deadener does not.
Is there a difference in Sound Deadener colour variations?
No, the logo Sound Deadener (Silver or Black) and OEM versions are the same product simply with a different colour/print on the aluminium face. Some customers are after the OEM finish in areas where the Sound Deadener will be exposed and they would prefer not to have logoing.
Do I need to wipe the panel before applying Sound Deadener or underlay?
Yes, for a successful bond between the product and the panel; clean the panel with a white based spirit such as wax and grease remover or methylated spirits.
Does sound deadening need 100% coverage?
No, it is unnecessary to apply deadener to over-lapped metal sections, top hat, chassis sections etc as these areas do not resonate. Moderate amounts of deadener make a significant difference. Once the middle of a panel has been covered, the additional deadener covering the panel has diminishing results. To engineer a car, it takes some skill and technical analysis to pinpoint key areas that need sound deadening, auto manufacturers do this and save money by only covering key areas. In reality most people will cover everything as they do not mind spending a bit more to ensure they have achieved the desired results. Keep in mind that this is one stage in controlling sound in your vehicle and stage 2 is just as crucial.
Do I need to heat Sound Deadener when laying sheets?
No, it does not need a heat gun to be applied. The adhesive backing is butyl based not bitumen.
Should I lay Sound Deadening sheets in some sort of order?
If you are doing the whole interior, we recommend doing the roof first and then any vertical panels and wheel arches. Finish laying the floor pan last so that you are not standing all over the butyl you have laid on the floor.
Will this Stage 1 Sound Deadener stop all noise?
Keep in mind that this is one stage in controlling sound and targets noise that is derived from panel resonance. Stage 2 products target droning and other external noises.
