FAQ
So FRP ye sen aluminium ma lɔre nipadua a ɛwɔ frigye mu?
Mpɛn pii no, FRP (fiberglass reinforced plastic) ye sen aluminium ma lɔre nipadua a ɛwɔ frigye mu efisɛ ɛma ɔhyew a ɛbɔ ho ban yiye (ɛnyɛ thermal bridging), ɛko tia nsunsuanso kɛse, ɛko tia nsɛe a ɛkorɔn, na ɛnyɛ den sɛ wobesiesie. Nanso, aluminium yɛ hare na ɛyɛ nea ɛyɛ fɛ kɛse. FRP ne nnwuma gyinapɛn ma awɔw nkɔnsɔnkɔnsɔn adwumayɛ dodow no ara.
FRP panel ahorow no di dwuma bere tenten ahe wɔ lɔre a frigye mu?
FRP panels a ɛyɛ papa taa di mfe 12-15 wɔ tebea a ɛfata mu ne mfe 8-10 wɔ mmeae a ɛhɔ yɛ hyew. Sɛ wosiesie no yiye (afe afe ahotew, UV protectant a wɔde di dwuma, wosiesie nsensanee ntɛm ara), FRP panels betumi atrɛw akodu mfe 15-20 adwumayɛ nkwa nna.
So wobetumi asiesie FRP panel ahorow a asɛe no?
Yiw, FRP panel ahorow no yɛ nea wotumi siesie. Wobetumi de fiberglass asiesie nneɛma ne gel coat asiesie mpaapaemu nketenkete ne ntokuru. Nea ɛnte sɛ aluminium anaa dade a ɛhwehwɛ sɛ wɔde welding (compromising insulation), FRP asiesie no nyɛ-structural na wobetumi ayɛ a wonnyi panel no mfi lɔre nipadua no mu.
