Ultra Flue Wrap

Ultra flue Wrap has been specifically developed and designed by IMS.

 Working with stove and chimney installers IMS developed the Ultra Flue Wrap. With an overall thickness of approximately 12mm, it provides a clean, quick and easy method to insulate flexi flue liners in the most awkward of chimneys.

Ultra Flue Wrap has a silicone coated glass cloth outer shell to repel moisture and unlike other products on the market, completely encloses the inner felt with glass cloth to minimise irritating fibres.

It has a secure fixing method incorporating a Velcro strip along its length together with two effective straps secured by stainless ‘D’ rings preventing snagging in the chimney. To aid installation further it has connecting straps to eliminate the challenge of sections becoming separated.

Our range of loose vermiculite is perfect for use with your flue liner. Designed to be poured down either side of a flue liner, loose vermiculite keeps the flue warm helping maintain an efficient draw and reducing condensation.

Vermiculite is a natural occurring mineral which produces a highly aerated insulating and absorbent material after thermal expansion.
