The Verplas Self-Seal Thermal is manufactured from Neopor® graphite impregnated expanded polystyrene (EPS) with infrared absorbers and reflectors, which significantly improves the thermal resistance of the material compared with standard EPS. The Neopor® material is fully tested to meet the thermal conductivity requirements of BASF - EN13163, to assist with the prevention of condensation and is Flame Retardant to DIN 4102 B1. Verplas Thermal Ducting has a minimum Density of 25 kg/m³ and therefore achieves a Thermal Conductivity of 0.03 W/mK, which at 20mm thickness, provides a minimum Thermal Resistance or R value of 0.666 m²K/W. This exceeds the current UK Domestic Ventilation Regulation requirements of: Part F 2010 Domestic Ventilation Compliance Guide and NHBC Guidance Document Chapter 3.2. Which states that the Thermal Resistance of the insulating material should be equivalent to a minimum 25mm, with a thermal conductivity of 0.04 W/mK which gives a minimum Thermal Resistance requirement of 0.625 m²K/W. The Verplas Self-Seal Thermal Ducting range has been designed to be installer friendly and utilises the patent pending push, click and lock mechanism. To ensure joint integrity and exceed the requirements set out in DW/143 Class A Leakage Test and DW/154 ductwork standards. The full range has also been independently airflow performance tested, by the Building A comprehensive range of fittings are available for each system size, including; Horizontal and Vertical bends, Tee-Pieces and Plenums and Ducting available in 1m and 2m lengths to provide a complete cost effective solution for individual installations, with minimum waste on site. Pre-packaged in boxes of 6 for all fittings and lengths of ducting, allows installers to carry multiple components to overcome tricky design changes on site. All Self-Seal Thermal systems are compatible for use only with Verplas standard PVC ducts and fittings.
