Anhydrite slowing screed (Gyvlon)

By replacing Portland cement with a calcium sulphate binder made from by-products of industrial processes, Gyvlon screeds avoid the energy-intensive processes of cement production, which reduces embodied carbon in the material by up to 86%.

All Gyvlon screeds and binders have third-party-certified Environmental Product Declarations (EPDs).

Reducing Lead Times And Improving Strength With Advanced Technologies

• Faster Drying (FD) technology accelerates moisture evaporation and allows earlier floor covering
• While its Early To Cover (E2C) technology improves surface strength and bonding, allowing tiles and vinyl to be applied securely at residual moisture levels from 1.5% moisture content

Gyvlon ECO FD E2C provides up to a 86% reduction in embodied carbon, and unlike traditional cement screeds requires far fewer expansion joints, allowing for:

• Larger uninterrupted floor areas
• Greater flexibility in tile sizes, layouts, and vinyl floor installations

Versatile Performance At Reduced Depths

Gyvlon ECO FD E2C builds on the range’s low-carbon mix design by incorporating fast drying and ‘early to cover’ technology, providing excellent versality for many applications such as:

• Thermal insulation
• Sound insulation
• Floor levelling

This screed is designed for installation from 30mm thickness (unbonded), with typical depths of 35mm for domestic floating floors and 40mm for commercial applications.

ThermioMAX FD E2C is designed specifically for underfloor heating systems, delivering outstanding thermal performance and efficiency:

• Up to 80% faster heat-up times compared to traditional cement screeds
• Efficient heating and cooling distribution throughout the floor
• Improved performance for boilers, heat pumps, and heating systems
• Reduced energy consumption and heating costs

Thin Installation, Designed For Modern Under Floor Heating (UFH) Systems

ThermioMAX can be laid from as thin as 10mm (bonded) or 15mm (floating) above pipework and is compatible with low-profile bonded UFH systems, providing a single screed solution across different systems, while maximising heating performance and system efficiency.

The Gyvlon Thermio range is certified by the British Board of Agrément (BBA) for its high thermal conductivity and efficient heat transfer.

XTR FD E2C is a high-strength screed for demanding environments, with a mix design engineered using selected aggregates to create a dense, self-compacting structure that provides:

• Exceptional strength
• Rapid installation and low shrinkage
• A smooth, level finish, and excellent long-term stability

Built For Heavy Loads And High Traffic, With Flexible Installation

XTR FD E2C delivers high mechanical performance (C35-F7), making it ideal for floors subjected to heavy loads and high traffic, including:

• Retail units
• Hospitals
• Busy commercial environments

The screed can be installed from 30mm thickness (unbonded), with typical depths of 35mm for domestic floating floors and 40mm for commercial applications.
