Modern & eco-friendly technology
SIP panels combine structure and insulation in a single factory-built element — enabling faster, cleaner, and more predictable construction.
What are SIP panels?
A SIP panel pairs a rigid insulation core with two structural facings to create one high-precision building element.
- Rigid insulation core for continuous thermal envelope
- Factory-cut OSB facings with sub-millimeter tolerance
- Hot-press bonding for structural integrity and uniformity
Thermal performance
Continuous insulation through walls, floors, and roof reduces thermal losses and supports lower operating demand.

Built for Portugal's climate
How SIP construction protects homes from Atlantic humidity, coastal wind exposure, and seasonal thermal fluctuations.
Portugal's Atlantic climate requires a stable, well-insulated envelope.
Along the coast, SIP panels provide continuous insulation that prevents moisture buildup even through stormy, humid, and windy conditions.
Year-round comfort from factory-engineered precision
SIP panel assemblies are manufactured under controlled conditions, ensuring consistent insulation thickness and structural integrity that performs reliably across Portugal's seasonal temperature swings.
Rigorous moisture protection
Continuous insulation reduces condensation risk on humid, stormy coasts
Thermos effect
Factory-engineered for year-round comfort in both winter and summer

Fire safety
SIP assemblies are specified with certified fire-resistant materials and project-appropriate build-ups aligned with local requirements.
Certified materials
Structural layers and insulation assemblies are selected from certified systems appropriate to the intended fire-performance class.
Regulation compliant
Wall, floor, and roof build-ups are coordinated with project documentation and local fire-safety requirements.
Certified and fire-tested
Technical fire-performance documentation can be shared on request with architects, engineers, and development teams.

Frequently asked questions
Common questions about SIP construction, timelines, and working with Den.
SIP (Structural Insulated Panels) are load-bearing building panels made from an insulating core bonded between two structural facings. Because they are factory-manufactured, they arrive with precise dimensions, consistent quality, and strong thermal performance. This allows faster assembly on site and a more continuous insulated envelope than many traditional wall systems.
Yes. When the project is designed with the right wall build-up, ventilation strategy, and detailing for the local climate, SIP homes perform very well in Portugal. Their continuous insulated envelope helps reduce condensation risk, limits uncontrolled air leakage, and improves thermal comfort through both humid winters and hot summer periods.
For a structural shell, SIP construction typically takes around 3 months from technical preparation to final on-site assembly. In practical terms, the process usually includes project adaptation to SIP logic, factory manufacturing of panels, delivery coordination, and then fast installation on site. Compared with many conventional methods, this reduces delays, improves precision, and shortens the critical construction phase.
Yes. SIP houses are known for high energy efficiency because the building envelope combines structure and insulation in one system. This helps reduce thermal bridges, lowers heating and cooling demand, and makes indoor temperatures more stable and comfortable throughout the year.
Yes. Existing architectural projects can usually be adapted to SIP construction without losing the main design intent. The adjustment process typically focuses on spans, junctions, panel module logic, and buildable detailing so that the house keeps its architectural character while becoming compatible with SIP manufacturing and assembly.
Yes. We can provide technical information on panel composition, performance values, assembly logic, and supporting documentation relevant to the project stage. For partners, architects, and serious enquiries, this can include the key specifications needed for design coordination, approvals, and feasibility review.
Yes. The sample house is located in Figueira-da-Foz and can be visited by appointment. During the visit you can see the build quality, spatial feel, finishes, and overall comfort of a real completed SIP home, which helps make the system much easier to evaluate than from drawings alone.
Yes. We work with architects, developers, construction companies, and investors who want to integrate SIP technology into residential projects in Portugal. Collaboration can include project adaptation, technical coordination, delivery planning, and support during the transition from concept to buildable SIP system.
