Warranty and certificates
Warranty terms differ between sellers, so ask for them in writing before you buy. One supplier's Hong Kong terms say the warranty starts on the date a brand-new, unused product is bought by the first user, so keep the sales receipt. Some materials are sold with claims of SGS testing and compliance with Hong Kong Indoor Air Quality rules; if the material goes inside the cabin, ask for the test report. The Noise Control Ordinance (Cap. 400) sets rules on products that do not meet noise standards, so a noise claim should also be stated in writing.
Season and timing
November falls between the hot summer months of June to August and the cooler winter of December to February. A heat barrier matters most in the hot months, so fitting in November means the material is in place before summer. Ask how long the fitting takes for the parts you choose.
Delivery and how prices are quoted
Prices are quoted per sheet, per roll, per pack or per kit, and sheets come in packs of 9 or 10 pieces. Coverage is given in square metres or square feet and sizes in millimetres or metres, so write your area in square metres and convert if a listing uses feet. Several sellers in the results are based overseas, so confirm delivery to Central, Kowloon, Sha Tin, Tsuen Wan or Tuen Mun and how long it takes before you pay.
What to write in your request
Give the car make, model and year, which parts you want covered (doors, floor, roof or firewall), and whether you will fit it yourself or want a workshop to do it. Say how many square metres you need, your city and your budget. If you want self-adhesive sheets, say so, since some decoupler products come with an adhesive backing and some do not.
