Tejas Borja is a worldwide leader in the production and distribution of ceramic roof tiles. Sourcing clay from Mediterranean quarries for over five decades, their products combine tradition, research, and leading design for seamless integration into contemporary projects with cutting-edge technology.
The BorjaTHERM insulated panels are made of a central core of polyurethane foam (a material with high-performance insulating properties), surrounded by a protective layer of aluminium foil and finished with an integrated Alu-Zinc batten to enable the fixing of the roof tiles.
Available thicknesses from 60 mm to 160 mm and steps of 370 and 395 mm as standard measures, being able to manufacture in other steps upon request. When installed on the roof structure, the panels form, due to the low thermal conductivity it has, an uninterrupted sheet of insulation of maximum energy efficiency: λ = 0,022 W/m•K, and totally free of thermal bridges.
Polyurethane foam is a solid and uniform material with a high insulating capacity thanks to its low thermal conductivity. BorjaTHERM panels are coated with aluminium, which, combined to the PUR foam becomes one of the best insulating materials in the building industry and guarantees the best thermal performance possible, along with being extremely lightweight, long-lastin,g and thermally constant (-50/+100°C), which makes it ideal for use under roof tiles.
The main component that gives its name to the roof system is the BorjaTHERM prefabricated panel. These prefabricated panels, which arrive at the build site ready to be installed, are made of:
- An exterior coating of embossed aluminium which covers the insulation on all four sides, acting as a protective and watertight barrier.
- A Thermal insulation made from rigid expanded polyurethane foam with a density of 39 kg/m3 and a thermal conductivity coefficient of λ = 0,022 W/mk.
- An Aluzinc ventilated profile, 41 mm high, designed to facilitate the support and fixing of the roof components. The large holes in the profile guarantee under-roof ventilation with a flow greater than 200 cm2 per m2 of batten.
An installation of BorjaTHERM panels on the roof structure fulfils, using just one product, all the functions of the 6 basic components of traditional ventilated roofs:
- Self-supporting roof structure
- Vapour barrier
- Low-transmittance thermal insulation
- Under-roof waterproofing
- Primary battens to create ventilation
- Counter battens

The panels are available with two batten spacing distances to enable the installation of the main ceramic tile models.
The Flat-10 tile can be installed on both models, thanks to its variable batten spacing. With slopes under 35%, we recommend the tiles be installed 370 mm apart.
The use of high-performance insulation systems in a refurbishment project or a new build is a direct and immediate way of achieving significant savings in energy consumption. A lower level of energy consumption results in lower CO2 emissions, which are responsible for global warming, thereby making a positive contribution to caring for the environment. Homes are responsible for a significant part of global energy consumption. As a result, particular effort must be made to design them to reduce energy loss as much as possible. Of all the energy lost from homes, approximately 30% is lost through the roof.
