Some nice progress of CTF Ultra VP and associated finishes being installed this week to new penthouse apartments in the heart of Hove for a key client. The CTF Ultra ® VIP range is a vacuum insulated panel system for use in flat roof applications where there are restricted heights such as door thresholds. These are being installed with Soprema Duoflex Hot melt systems to the terraces and Alsan cold liquid waterproofing to the balconies.
