Beschreibung
Zusammenfassung:	A hollow spacer tube 10 for a multiple glazed unit in which said hollow spacer tube 10 is fitted between at least two glazing panes 12 and the body of the hollow spacer tube 10 comprises a thermoplastic material with fibres and is bonded to a gas-impermeable polymeric tape 14 facing away from said cavity so that in use the tape 14 will resist gas leakage through the hollow spacer tube 10. Preferably the tape is a formed from polyester and secured to the hollow spacer tube via a self adhesive back. The hollow spacer tube may be formed from a thermoplastic polypropylene and the reinforcement fibres may be glass fibres. The spacer may contain a molecular sieve, or desiccant, 13 for absorbing moisture and have breather holes 11 for allowing the passage of air into the spacer.
