The evolution of the roof, in its installation too
For centuries, the roof has been the shield of the home. Today, as well as protecting, it must insulate, ventilate and optimise energy consumption.
The new requirements of the Spanish Technical Building Code and energy-efficiency targets call for building systems that improve the thermal performance of the building envelope.
The BorjaSystem installation system lays the foundations for meeting these requirements.
Mortar installation
Most problems in pitched roofs are not in the tile, but in how it is installed.
Using mortar creates stresses, blocks ventilation and compromises the durability of the system.
- Damp and leaks
- Internal condensation
- Structural overload
- Cracks and breakage
- Lack of ventilation
BorjaSYSTEM installation
The BORJASYSTEM installation system sets out the criteria for completely dry-laying the roof, with no mortar used anywhere.
- Continuous ventilation
- Improved thermal insulation
- Reduced condensation
- Greater durability
- Lighter installation
When it comes to roofing, correct installation is as important as the finishing material.
