About Our 25 Year Guarantee

Kompozit’all UK Ltd Offers A FULL 25 Year Guarantee

Kompozit’allUK Ltd guarantees all FuranFLEX25 and VentilFLEX25 product against any material manufacturing fault for a period of 25 years from the date of installation. This means that the value of ‘cover’ and compensation will remain at 100% for the FULL 25 years (not reduce with age like others in the industry).

For this guarantee to apply, the FuranFLEX25 or VentilFLEX25 product must have been installed by a registered Company with Kompozit’allUK, where all the personnel have current certification and that the Kompozit’allUK method, as detailed in the technical manual, has been fully adhered to throughout the process.

We will be responsible for reinstallation in the case of a manufacturing fault in the liner. This guarantee is believed to be unique, as it does not reduce in cover with age and is only possible due to the quality of our manufacturing control, strict procedures, regular training updates and technical support.

What Is an Insurance Backed Guarantee (IBG) & Why Do We Need It?

Evolution Insurance, the underwriter, provides a Policy of Insurance to meet claims under the Kompozit’allUK guarantee for the first 20 years, in the unlikely event that Kompozit’allUK Ltd has ceased to trade. ‘This is a unique level of cover on a UK installed product and is based upon the controls that Kompozit’allUK demonstrate’.

What Is Covered?

This is a unique 20 year independent Insurance Backed Guarantee .
The Insurer agrees to indemnify the Insured in respect of the cost of making good defective workmanship and/or faulty materials in the original Installation at the location described in the Certificate of Insurance ,arising during the Period of Insurance, where the Contractor has Ceased Trading and is unable to honour the terms of their own Contractor’s Written Guarantee issued to the Insured.
