Description

The Warmup Contura Floating Floor System insulates and heats dry construction floating floors. Floor finishes can be laid over the Contura System immediately after installation, unlike screeded floors which require time for the screed to cure. Replacing a traditional screed with thinner and lighter dry flooring panels significantly reduces the heated floor mass.

Consequently, the Contura System responds faster to heating demands than traditional screed systems. This faster warm up and cool down time is recognised within SAP with the calculated energy usage reducing as a result. The reduced system mass also has other benefits especially for multi-storey developments. The reduction in weight associated with moving from a screeded floor to a dry floor can have a significant impact on the structural requirements of a building leading to cheaper foundations and structural elements throughout the project.

The Contura Boards are simply laid over a flat and level (SR1) subfloor, the diffusion plates and pipe are then fitted into place.

Diffusion plates:

The Warmup Diffusion Plates are press-formed heat-diffusing aluminium plates. They are lightweight and easy to install, creating a responsive, efficient underfloor heating system with an even heat distribution.

Panels:

Warmup Contura expanded polystyrene (EPS) Insulation is a routed EPS insulation board for use in conjunction with Warmup Diffusion Plates. The insulation boards are provided in 1250 x 600 mm sheets and are available in 30, 40, 50, 60, 70, 80, 90 and 100 mm thicknesses.

This type of insulation is primarily used in new build on upper floors where insulation levels are higher which will lower heat requirements and can be installed under almost any type of floor finish.

Pipework:

The Warmup PEX-A pipe is formed as a single extrusion with an adhesive layer and EVOH oxygen barrier. The EVOH layer restricts the ingress of oxygen into the heating system, reducing oxidation of critical components in the primary system and extending their service life.

The minimum 70% cross-linking within the polyethylene (PE) material provides superior mechanical properties to the pipe, with a maximum working temperature and pressure of 95°C and 6 bar respectively. The PEX-A pipe has a high thermal conductivity of 0.41 W/mK, substantially greater than an equivalent polybutylene pipe at 0.22 W/mK. This enables the systems to emit between 3% and 6% more heat from the same water temperature as equivalent systems using PB pipe.

The Warmup PE-RT pipe is a five layer extrusion of polyethylene of raised temperature resistance. It is manufactured as follows, PE-RT/ Adhesive/ Oxygen barrier (EVOH)/ Adhesive/ PE-RT. This type of pipe is suitable in situations where there is an absolute guarantee that temperatures above 70ºC cannot be generated. This is a cost-competitive pipe and is ideal for all types of installations.

Manifold:

The Warmup Stainless Steel Manifold range provides flexible zoning and water regulation for 2 to 12 underfloor heating circuits. Supplied complete with Taconova Flow Meters, Fill/ Drain Valves, Air Vents and a Thermomanometer, it is equipped with all the features needed to commission an underfloor heating system quickly and confidently.
