ISOLINE Tile Underlay Waterproofing Board
Tile roofs are among the most attractive and functional elements of traditional architecture. However, without a reliable roofing substrate, problems such as water leakage, condensation, mold, rot, and heat loss can develop over time.
The ISOLINE Tile Underlay Waterproofing Board is a high-performance roofing solution designed to provide 100% waterproof protection beneath all types of tiled roofs.
Key Features and Benefits of ISOLINE
- 100% Waterproof Protection – Safely channels any water penetrating beneath the roof tiles directly into the gutter system.
- Ventilated Design – Reduces condensation while protecting the roof structure against moisture and mold.
- No OSB Required – Installs directly onto spaced timber battens, reducing timber consumption by up to 70%.
- Fast and Easy Installation – Minimizes installation time and labor costs.
- Prevents Tile Slippage – Special recessed profile keeps roof tiles perfectly aligned.
- 10-Year Warranty – Provides long-lasting, reliable roof protection.
- Environmentally Friendly Material – A sustainable and safe roofing solution.
- Compatible with All Roof Tiles – Particularly well suited for Marseille-style roof tiles.
ISOLINE does much more than provide waterproofing—it helps create roofs that are durable, quiet, visually appealing, and built to last.
Where Can ISOLINE Be Used?
ISOLINE is suitable for:
-
New roof construction
-
Roof renovation and refurbishment projects
-
Residential housing developments
-
Private homes
-
All pitched roof structures
Existing roof tiles can often be reused during renovation projects, helping reduce overall costs. Once the roof is covered with ISOLINE, it remains completely waterproof—even before the roof tiles are reinstalled.
Condensation Control and Roof Ventilation
The integrated ventilation channels beneath each board allow moisture to escape from the roof structure.
This helps to:
-
Reduce moisture-related deterioration of roof tiles
-
Prevent mold, mildew, and corrosion
-
Improve the effectiveness of thermal insulation
The result is a healthier, longer-lasting roofing system.

Frequently Asked Questions
Is ISOLINE compatible with all roof tiles?
Yes. It is compatible with most roof tiles and is particularly well suited for Marseille-style roof tiles.
Is OSB roof decking required?
No. ISOLINE is designed to be installed directly on spaced timber battens, providing significant material savings.
Can existing roof tiles be reused during renovations?
Yes. Existing roof tiles can be reinstalled, making renovation projects more economical.
Will the roof remain waterproof before the tiles are installed?
Yes. ISOLINE alone provides a completely waterproof temporary roof covering, protecting the building throughout the installation process.
Can thermal insulation be installed together with ISOLINE?
Yes. Thermal insulation materials can be installed beneath the ISOLINE boards to improve the roof's overall energy efficiency.
