押出ポリスチレン(XPS) Extruded Polystyrene Foam (XPS)

XPSは、ポリスチレンと不燃性のフッ素化塩素化炭化水素(FCKW)より製造される。特に、Wedi Building社のXPSは、100%耐水性、結露防止性、耐圧縮性が大きいので、普通より高度に設計される空間に使われる。XPSは、曲げ弾性率が高 く、耐久性があるため、断熱材として使用される。切断行程において、粉塵の発生は少ない。

XPS is made using polystyrene granulate and an FCKW free blowing agent which helps injecting the foam into a block form creating a naturally dense and closed cell consistency of the finish material. XPS backer boards like Wedi building panel are 100% waterproof, water vapor retarding and so dense that they can be used on heavy duty floors. They provide excellent flexural and breaking strength allowing for a solid wall backer board installation.

- 大変優れた断熱材(オランダの家の例では電球の使用だけで暖房器具の必要なし)
- Lotusanを表面に施す場合は特に長期的に性能保持
- 軽量
- 取り扱い易い / 切断の際に切れ目がきれい。
- Very good isolation (house build in Holland can be heated with a light bulb)
- long lasting specially if coated with Lotusan
- Light weight
- Easy handling / makes clean cuts when sawed.
- If simple construction is used no frame is needed.
