DOWLEX 14mm PE-RT Teava Multistrat

• Dowlex 2344 or PE-80, PE-RT Type I resin
• Manufactured to the highest standards
• KIWA / KOMO approved
• EVOH oxygen barrier layer (DIN 4726)

The high performance PE-RT pipe is manufactured by an addition of chemicals to the polyethylene raw material. This increases the strenght of the pipe which allows PE-RT pipes to be succesfully used for underfloor heating systems. This pipe is highly flexible, easy to use and has very good creep strength. In addition, the pipes have a high stability against stress corrosion.

Construction of the DOWLEX  multilayer PE-RT heating pipe

a. PE-RT, Type 1

b. Adhesive layer

c. EVOH oxygen barrier

Maximum length per port with the 14mm PE-RT pipe

The maximum length per port for PE-RT tubes with a diameter of 14mm is 100m (greater lengths result in too much pressure loss).

When making use of the 25mm dry floor system, a pipe spacing of 12.5cm is used for main heating (approximately one port per 10m²).
