Caltech UV

Caltech Full Build Up

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.

Key Features & Applications

  • Waterproofing of flat and pitched roof structures, communal walkways, podium decks and terrace roofs
  • For new build construction and refurbishment projects
  • Applicable to existing concrete, roofing felt, brickwork, asbestos cement decks (subject to condition and priming requirements)

Characteristics and Advantages

  • Caltech UV is a single component product that requires no mixing therefore is easy to use and ready immediately
  • Fully Cold-applied so requires no heat or flame
  • Economic – provides a cost efficient life cycle extension of failing roofs
  • Retains flexibility at low temperatures
  • Minimal disruption and low maintenance
  • Can be applied all year round above 2°C
  • Approved to ETAG 005 (Part 6)

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
  • Do not use Caltech UV for indoor applications

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.
