FAQs
Frequently Asked Questions (FAQs) About PAVATAPE 75-150 Installation
What is PAVATAPE 75/150 and what is it used for?
PAVATAPE 75/150 is an aluminium-laminated butyl rubber tape designed for weatherproof, water-tight and UV-resistant sealing of board joints, connections and penetrations in PAVATEX insulation and under-roof systems. It helps prevent moisture and air ingress between timber-based boards and at critical junctions.
What sizes does PAVATAPE come in?
PAVATAPE is available in two widths: 75 mm and 150 mm, with typically 20 m roll length. The 150 mm width is generally used for larger joints, board overlaps and connections at the plinth level.
What are the temperature limits for installing PAVATAPE?
PAVATAPE can be applied in temperatures from +5 °C to +40 °C.
Do I need a primer before applying PAVATAPE?
Yes. When installing tape on wood fibre boards or other porous/mineral surfaces, a primer such as PAVAPRIM should be applied first to improve adhesion and ensure a lasting seal. 1L of Pavaprim covers 25lm of Pavatape 150, or 55lm of Pavatape 75
How should PAVATAPE be installed?
1. Prepare the substrate: Ensure surfaces are clean, dry and dust-free.
2. Prime porous surfaces: Apply PAVAPRIM and allow it to air.
3. Apply the tape: Remove backing and press the tape continuously by hand.
4. Final sealing: Use a pressure roller to ensure good adhesion and avoid wrinkles.
For best results, install PAVATAPE shortly after laying boards and before counter-battens are fitted.
Where should I use the 150 mm tape versus 75 mm tape?
Use PAVATAPE 150 mm for main board joints such as the ridge and large connections. For narrower gaps, small penetrations and detail taping, the 75 mm version is recommended.
Can PAVATAPE be exposed to weather?
Yes. The aluminium-laminated butyl composition is weather-resistant and UV-stable, making it suitable for external applications when integrated correctly within the system.
What are the key benefits of PAVATAPE?
• Durable and UV-resistant sealing
• High adhesion strength in hot and cold conditions
• Robust and tear-resistant tape
• Does not contain solvents or bitumen
What should I consider during professional installation?
• Apply tape before mechanical fixings like counter-battens.
• Always check the substrate is clean and free of dust.
• Follow the manufacturer’s sequencing and overlap details for complex junctions (e.g. chimneys, penetrations).
Good preparation and correct tape placement ensures air-tight and water-tight performance.
How long should boards be taped after installation?
The general guideline is to tape joints soon after board installation to avoid dust, movement and potential gaps forming between elements.
