Vortice has launched the Vort HRI Phantom, a brand new, slimline, void mounted heat recovery unit ideal for commercial applications. There are two models available with performances ranging from 206m3


/hr to 350 m3 /hr. Fresh air is 100 per


cent fully filtered even in bypass mode improving the indoor air quality within the room. The quality of the air can be further advanced by using the new Vortice NOX filters. The centralised ventilation units each have a high efficiency counter cross flow heat exchanger with frost protection and easily accessible filters. The units come complete with a wired remote control unit with LCD allowing initial configuration and commissioning, speed selection, display of the time, room temperature and filter status.

New research has shown that by using premium performance phenolic insulation over cheaper, thicker mineral fibre insulation, developers can reduce construction thicknesses and actually save on total upfront costs. The analysis, carried out by an experi-


enced quantity surveyor, considered several variables including the cost of the insulation materials, length of wall ties, area of roof and wall layers and the foundation width. The results showed that by using the Kingspan Kooltherm K106 Cavity Board specification, overall construction costs were reduced by £161 and £420 in the large and small detached houses respec- tively.
