Frequently Asked Questions

What does Design Engineering Inc. make?

Design Engineering Inc., or DEI, makes thermal and acoustic control products, including heat barriers, sound deadening, exhaust wrap, reflective sleeving and protective insulation for performance and classic vehicles.

Why use DEI heat and sound insulation?

DEI insulation reduces cabin heat and noise, protecting interiors, wiring and components from engine and exhaust temperatures. It makes classics and hot rods far more comfortable to drive.

What is DEI exhaust wrap used for?

DEI exhaust wrap insulates headers and pipes to keep heat inside the exhaust, lowering under-bonnet temperatures, improving flow and protecting nearby components on performance and custom engine builds.

Where should I fit DEI heat barriers?

DEI barriers commonly go on floors, firewalls, transmission tunnels and under bonnets, targeting the hottest areas to shield the cabin from radiant and conductive engine and exhaust heat.

Does heat insulation help in Australian conditions?

Yes. With high summer temperatures, DEI heat control products help keep classic car interiors cooler and more comfortable, while protecting wiring and trim from harsh Australian under-bonnet heat.

Where can I buy DEI products in Australia?

Cruisin Automotive stocks Design Engineering Inc. heat and sound control products, importing genuine US insulation, wrap and sleeving to Australian enthusiasts at competitive, freight-conscious prices.
