Ibitambaro byo gukingira ubushyuhe
1. Ubushyuhe bwo hanze buri munsi ya −20°C, ubushyuhe buri munsi ya 5°C. Ubugari bwa 5mm bushobora kugabanya ishoramari mu bikoresho bishyushya no gukonjesha ho 60%.
2. Ingano nto yoroshya ububiko kandi ikagabanya ikiguzi cyo gutwara.
3. Ugereranyije n'ibikoresho bisanzwe byo gukingira, ipamba yo gukingira irapfunyika yoroshye gushyiraho, bigabanya igihe n'ikiguzi cyo kubaka.
4. Igihe cyo gukora cy'amashuka asanzwe yo gukingira ubushyuhe ni imyaka 5, mu gihe amashuka mashya yo gukingira ubushyuhe ashobora gukoreshwa mu gihe cy'imyaka 10.
