Ecoscreed Standard Code 6 : Energy Saving Zero Carbon Flowing Screed

A pre-mixed, bulk flowing floor screed based upon a special hard variety of calcium sulphate. The product is eco-friendly and incorporates 100% replacement of natural sand by recycled glass sand.  The screed can be laid thinner than conventional screeds and up to 1000 m2 per day at 50 mm can be achieved, thereby making it highly competitive in overall time and cost savings compared with conventional sand and cement screeds. It should be installed either as an un-bonded screed or as a floating system in both new build and refurbishment projects. Ecoscreed Standard is ideal for use where under-floor heating and cavity floor systems are being installed and due to the thermodynamic properties of glass it can save as much as £2.00 /m2/year on the heating costs. The fluid nature of the flowing screed allows full contact with and encapsulation of the heating pipes and floor elements. Ecoscreed Standard Code 6 is suitable for all types of floor covering but should not be used as the final floor finish.

Applications: (Ambient temperature to be a minimum of 5 degrees centigrade)

Un-bonded:

• Minimum thickness: 30 mm. – Fix 5 to 10 mm border edging strip to all walls.
• Use lapped single sheet polythene not less than 500 gauge
• Use unfolded polythene on rolls (folds act as crack inducers).
• Tape all overlapped polythene edges except at border edge.

Floating:

• Minimum thickness of 40 mm.
• Polythene to be placed on top of insulation.
• Insulation to be laid in accordance with the manufacturers recommendations.

Under floor heating system.

• Minimum screed thickness clearance over top of heating pipes to be 30 mm.
• Heating pipes should be secured from lifting.

Thin section coverings: If there is a requirement for direct fixing of thin section final finishes, such as vinyl, linoleum, etc. then the floor should be lightly sanded after 24 hours to remove any surface imperfections.

Need for joints:

• Under-floor Heating: Suitable joints to be made.
• Un-bonded: Joints are needed when the length to width ratio is less than 3:1.

Compressive strength: > 10 N/mm2 at 1 day; > 25 N/mm2 at 28 days.
Flexural strength: 3 N/mm2 at 1 day; 5 N/mm2²at 7 days; 8 N/mm2 at 28 days.
Yield: 1.85 kg/mm/m2
Reinforcement: No requirement for reinforcement.

The Energy Saving Screed Co Ltd can also provide a design and specification service and it is recommended that they are consulted early in the design process.

ECOSCREED RAPID Code 6 : Energy Saving Zero Carbon Flowing Screed

A premixed, protein free, rapid drying internal flowing pumpable screed, specifically designed for thick section flooring applications where speed of return to service is of the essence. Ecoscreed Rapid incorporates 100% replacement of natural sand by recycled glass sand and is therefore a more environmentally friendly floor screed than any others containing conventional quarried aggregate or sand. Ecoscreed Rapid is ideal for use where under-floor heating and cavity floor systems are being installed and due to the thermodynamic properties of glass it can save as much as £2.00 /m2/year on the heating costs. Ecoscreed Rapid has been designed to solve the problem of slow drying times associated with existing pumped alpha-hemihydrate / anhydrite calcium sulphate or sand and cement screeds. The material can be walked on after 4 hours at a thickness of 30 mm and final floor finishes can be applied after 7 days at 20°C. It can be laid thinner than conventional screeds and up to 1000 m2 per day at 50 mm can be achieved. The screed can be installed as either a bonded, unbonded or floating system in both new build or refurbishment projects. The material is ideal for cavity systems and under floor heating installations.
