In the construction of passive houses and ultra-low energy residences, door and window openings are the largest thermal bridge loss points in the building envelope. Traditional steel and wood-plastic composite subframes have high thermal conductivity, which easily leads to heat loss, condensation, and mold growth on the walls. Graphite polystyrene subframes rely on graphite polystyrene...

Window and door openings are the biggest thermal bridges in a building envelope. Ordinary steel and wood-plastic composite subframes have high thermal conductivity, allowing hot and cold air to continuously penetrate, causing condensation and soaring energy consumption. Graphite polystyrene subframes, using high-density graphite polystyrene as the base material, are specifically designed for passive houses.

In building energy-saving renovations and new ultra-low energy consumption projects, graphite polystyrene (SEPS) has become an industry trend in replacing traditional polystyrene boards. Its performance advantages are not simply due to the addition of graphite, but rather the synergistic effect of the material's microstructure and formulation system.

Under the dual-carbon strategy, building envelope insulation materials are undergoing a comprehensive upgrade. Graphite polystyrene (SEPS), with its modified graphite composite technology, has become the core material for passive houses, ultra-low energy consumption residences, and public building exterior wall insulation, completely solving the problems associated with traditional E...

The engineering effect of graphite polystyrene boards depends not only on the properties of the material itself, but also on scientific selection and standardized construction techniques. The quality of products on the market varies greatly; inferior boards are prone to problems such as insulation failure, inadequate fire resistance, cracking, and peeling.

With its comprehensive advantages of thermal insulation, fire resistance, durability, environmental friendliness, and ease of construction, graphite polystyrene board is suitable for most building insulation scenarios, covering multiple fields such as civil buildings, public works, industrial facilities, and special buildings. It is currently the most widely used building insulation material.

To fully leverage the supporting role of high-quality materials in improving building quality, explore the application practices of high-quality building insulation technology, and contribute to the construction of "good houses" that satisfy the public, on the afternoon of May 27, 2025, a seminar was held by the Ministry of Housing and Urban-Rural Development's Science and Technology and Industry Department.

On October 23, Mr. Wang Wei, Deputy Chief Engineer and Dean of the Engineering Institute of China Academy of Building Research and China Construction Technology Group, along with Mr. Zhang Xiaomin and Ms. Yang Xiaobin from Sinoma Green Building, visited and provided guidance to Geyade. Geyade's leaders led the group on a comprehensive understanding of the super...
