Would you like to use a flooring substrate that can provide both insulation and soundproofing to comply with the revised Energy Conservation Act?

According to the revised Energy Conservation Act for Buildings, all new buildings must comply with the "Energy Conservation Standards" starting in 2025. Floor insulation is one of the key points for the longevity of buildings. Are you looking for a flooring substrate that combines soundproofing and insulation? Product Name: Chardan SPF400 【Features】 ✔ Low height of 40mm! ✔ Integrated soundproofing and insulation unit ✔ Reduced construction time to less than 1/3 compared to dry double flooring! (In-house research) ✔ Achieved LL-45 with SPC flooring! A multi-type that does not limit the choice of top materials It has achieved performance with SPC flooring, which is said to be thin and hard, making it difficult to ensure soundproofing performance. Since it is a form filled with special sound-absorbing material in the underfloor space, it provides both floor soundproofing performance and insulation effect simultaneously. By using dedicated edge treatment materials and fastening components, we have realized innovative construction that reduces construction time and soundproofing work.
