Extensive Gypsol product range

In addition to our Gypsol Classic screed, we have developed a range of exclusive products. Each of these, such as the recently released Gypsol Rapide screed, allow you to incorporate our materials into just about any construction project.

Easy to place, self-compacting, free-flowing anhydrite screed binder

An extensive range of offsite mixing plants uses our Gypsol. Providing you with the following benefits:

This way of working significantly reduces the negative impact on the musculoskeletal system of installing contractors.

Sustainable screed solution

We work tirelessly to reduce our carbon footprint, and to educate our customers and clients about how they can use Gypsol screeds to help minimise their environmental impact. As a result of our work on the sustainable credentials for our material Supply Chain School for Sustainability awarded us a Silver status.

Gypsol screed offers:

• Low manufacturing carbon footprint
• Low embodied energy
• Low operating energy
• Reduced lifetime impact
• Low-temperature underfloor heating
• Low toxicity
• Safer work environment
• Low cost

A true environmental-friendly, cost-effective and easy to apply alternative to traditional floor screed.

Low manufacturing carbon footprint

Our audited and certified carbon footprint certification states that we produce just 26.26 kg of carbon dioxide per 1 tonne of material we manufacture. This offers very significant carbon savings compared to traditional sand cement screed. You could save more than 95% of the carbon emissions associated with the manufacture of your floor screed by swapping from regular sand cement to Gypsol screed. Find out more in our carbon footprint guidance sheet.

Low embodied energy

Gypsol screeds can be used to significantly thinner depths than traditional screeds, and as a result, reduce the level of embodied energy by merely reducing the number of building materials used. For example, in a block of apartments where there are two stories, a total saving of 75mm in the floor screed depth is achievable. This means that you can eliminate one full course of bricks. The more floors there are, the more significant these savings become.

Low operating energy

The more you reduce the energy used during the operational lifetime of a building, the better the impact on the environment. As Gypsol screed can be laid much thinner, this presents the opportunity to increase the depth of insulation under the screed without impacting on the overall floor height, thus reducing heat losses through the floor and making the building more efficient.

Reduced lifetime impact

Gypsol screeds are 100% recyclable, which has a significant effect on the lifetime analysis of a building. We, therefore, are proud to say that Gypsol is a sustainable screed when you compare this to the traditional floor screeds.

Low-temperature underfloor heating

When using embedded or underfloor heating, the key to efficiency is high thermal capacity and high thermal conductivity, which leads to a fast response to ambient temperature changes. Gypsol screeds can offer high thermal conductivity as high as 2.5 W/mK (average 2.3W/mK) compared to sand cement screed, which is typically only 1.1W/mK.

This coupled with the thinner section leading to reduced mass and the intimate contact with the heating conduits leads to an underfloor heating system which has an extremely rapid response and which can run at temperatures very significantly lower than any competing systems. Add to this the increased insulation depth, which further enhances the floor’s thermal performance resulting in a floor that offers a very high coefficient of performance

Low toxicity for Gypsol binder

We manufacture Gypsol binder from a by-product of the chemical industry. This material would previously have found its way to landfill. We remove this material entirely from the landfill cycle thus eliminating this issue. For every 1 tonne of Gypsol binder used 0.98 tonnes of landfill is avoided and for every 4 tonnes of gypsum waste removed from the landfill cycle 1 tonne of hydrogen sulphide gas is avoided. Additionally, Gypsol screeds emit no VOCs.

Safe to work with Gypsol screed

Gypsol binder does not contain Portland cement. Portland cement contains chromium 6 which has a well-documented link to both acute and chronic health issues for those exposed to it. The use of Gypsol binder avoids these issues altogether. Gypsol screed is supplied ready to use and avoids most of the manual labour and health and safety risks associated with site-mixed sand cement screed. Installation of Gypsol is carried out using specialist pumping equipment and does not require the installer to be on his hands and knees and, as Gypsol is fully self-compacting, it will significantly reduce the effect on the musculoskeletal system of installers.

Low cost

Trained installers lay Gypsol screeds to exacting standards. Therefore, it is highly unlikely that you will need costly smoothing compounds. Additionally, when using some floor covering products, e.g. for some tiling adhesives, you can avoid the use of primers. Gypsol Diamond offers the opportunity to use the screed as a wearing surface with no requirement for subsequent floor coverings.

Gypsol origin

We manufacture Gypsol anhydrite binder to CE certified standards in the UK.  LKAB Minerals produce Gypsol binder from a by-product which we retrieve from the chemical industry. Previously this product was used as landfill.
