Overview

Caltech UV High Performance Roofing Systems comprise a single-component, cold-applied, fully reinforced moisture-triggered polyurethane based membrane, insulation boards and air and vapour control layers (AVCL). Caltech UV is applied in liquid form in two layers with an embedded reinforcing glass fibre matt to form a seamless, durable, smooth waterproof finish. The system is fully adaptable to meet the individual requirements of every project for use across all building sectors in both refurbishment and new-build roofing projects.

Application Details

Quality of substrate must be assessed before application (see product datasheet)
When preparing substrate the surface must be sound, of sufficient strength, clean, dry and free of dirt, oil or grease. In cases of cementitious substrates outgassing must also be taken into consideration
Surface must be dry and within +2 °C min. / +30 °C max
Gently stir the Caltech UV before use
Apply Caltech UV using a roller

Quick Tip

What is UV Degradation?

Many natural and synthetic
polymers are attacked by
ultraviolet radiation, and products using these materials may crack or disintegrate if they are not UV-stable. The problem is known as UV degradation, and is a common problem in products exposed to sunlight. Continuous exposure is a more serious problem than intermittent exposure.
