CEO, Gary Wilmot and Business Development Director, Caroline Rowley

As published on Larder, Kilwaughter Minerals has enhanced its portfolio of industry-leading products with the launch of its K Rend Eco Range which offers a suite of reduced cement render and mortar products.

Designed with innovative cement replacement technology, the range represents a significant investment from Kilwaughter and boasts re-engineered formulas for three existing products – K Post, GP Mix and Mineral TC – significantly reducing embodied carbon in the manufacturing process by up to 56%.

Developed by K Rend’s research and development team, the launch of the K Rend Eco Range underscores Kilwaughter Minerals’ dedication to improving environmental standards in the construction industry, promoting sustainable practices and meeting the demands of eco-conscious customers.

Caroline Rowley, Business Development Director at Kilwaughter Minerals, said:

“The launch of K Rend’s Eco Range reinforces Kilwaughter Minerals’ position as an industry leader in the UK and Ireland construction market. Sustainability is one of our core values and was very much a key focus during the concept, design and manufacture of this suite of products.

“This new range of sustainable products delivers reduced embodied carbon, providing choice to our customers while contributing to a cleaner environment, and maintaining the high level of performance customers expect from K Rend.

“As a responsible manufacturer, Kilwaughter Minerals is committed to innovating to get the best outcomes and to lead by doing so.”

Each product within the range is designed with enhanced sustainability features tailored to its specific function. K Post, a premium rapid-setting concrete, comes ready-mixed and is packaged in eco-friendly 20kg showerproof bags.

GP Mix is a versatile grey ready-mixed product which can be used as a render, mortar or plaster now offering improved workability and faster drying times, while Mineral TC is a low-maintenance, through-coloured thin coat render available in a variety of colours to suit individual taste and project style.
