LIQUIROOF P OSB 3 from EAP – Thermal insulation and seamless sub-structure in one working step.
LIQUIROOF PIR insulation boards deliver a super-flat surface ideal for liquid and flat roofing systems. Liquid waterproofing coatings are typically between 1.25 to 2mm thick meaning even the most minor imperfections in the substrate surface can create alignment issues and stress points on the outer surface coating. LIQUIROOF fully supported boards interlock on all 4 sides, from top to bottom, to create a strong and solid surface with no raised edges, misalignment or gaps.
Faced with a lightweight 8mm OSB 3 panel on the topside, LIQUIROOF panels are designed for use on old or new boarded structures. The polyurethane rigid foam insulation core provides maximum insulation with minimum panel thickness. The serrated edges on the boards slot together easily to cover large uneven surfaces, and with minimised alignment time are quick to install.
Key Benefits
- No coating stress points
- No surface crushing during installation or maintenance
- No delamination
- No vapour escape at board edges
- Compatible with; Liquid Applied Systems, felt and EPDM
- Thermal Conductivity:0.022W/mK
- Panels can be cut to size with standard tools
It is recommended that the deck is covered with a suitable vapour barrier and the insulation boards fixed using Guardian Thermally Broken Fixings.
The LIQUIROOF P OSB3 rigid panels can be installed over:
- Concrete
- Wooden boarding
- Plywood panels
- Steel profile sheets
- Over existing roof spaces as a recovery board
Life Expectancy
Providing it has been installed in line with the manufacturer’s recommendations, LIQUIROOF is designed to last the life of a building with the board retaining its U-value as well as its structural and acoustic integrity.
