In 2014, IKO were approached by Westminster Cathedral’s architect to discuss renewing its mastic asphalt roof coverings with the IKO Permaphalt Polymer Modified Mastic Asphalt System.

IKO assigned the job to Knight Asphalte – one of their approved contractors – who installed around 35 tonnes of IKO Permaphalt throughout the project.

IKO’s range of specially formulated mastic asphalt roofing solutions, use advanced polymer technology giving the ideal combination of long-term durability, increased fatigue resistance, improved temperature stability and ease of installation.

For this particular project IKO Permaphalt system was utilised due to its range of market leading benefits including; a completely seamless waterproofing finish, high temperature stability, enhanced fire performance ratings due to IKO Permaphalt being virtually incombustible, excellent acoustic performance, being suitable for roofs exposed to foot traffic, environmentally friendly – part of our Carbon Zero initiative – and being covered by a comprehensive range of long term guarantees.

Mastic Asphalt provides an environmentally friendly project from start to finish

IKO and their contractors are always thinking about the impact of their work and thanks to this, were able to calculate the impact Westminster Cathedral’s work had on the population.

For every single tonne of Mastic Asphalt they make they contribute to environmental and humanitarian causes, and for this project alone, the result was 5.5 tonnes of CO2 offset.

The net carbon footprint of this project is entirely offset using internationally approved carbon credits, which means for every tonne of Mastic Asphalt made, IKO are helping to fund environmental and humanitarian causes.
