TECHNICAL SOLUTIONS FOR HOMES

Details for a house with steel structure

This guide covers the main systems that influence the performance of the building envelope and the construction joints in a steel-framed house.

Foundations

Slab, footing, and support solutions coordinated with anchors, insulation, and facade base.

Floor Slabs

Floor and slab solutions, connections to the facade, and coordination with interior partitions.

Facades

Sandwich panels, SATE, ventilated facades, and solutions for openings, corners, and subframes.

Covers

Flat and sloped roofs, roof slopes, eaves, gables, ridges, and gutters.

FOUNDATION

Foundations for houses with steel structure

The foundation for a steel-frame house is determined based on a geotechnical study, the loads, and structural calculations. This guide compiles various foundation solutions used as a reference for StarModul housing projects.

Reinforced concrete slab

Continuous on-site support solution. The reference technical drawing shows a slab with insulation and associated barriers; the final thicknesses and reinforcement are determined on a project-by-project basis.

Running shoes

Reinforced concrete foundation to provide linear support for the structure. Dimensions, reinforcement, and geometry depend on the soil conditions and the loads on the house.

Cavity-Type Foundation

Solution coordinated with the layout, base plates, and anchors of the steel structure, specifically designed for the project.

StarModul Ventilated Floor

Elevated solution above ground level using a steel structure calculated for the dwelling and compatible with sandwich panels within the construction system.

How the foundation is coordinated with the steel structure

The connection between the foundation and the structure must be defined during the layout phase to ensure proper support, anchoring, elevations, and continuity of the exterior walls.

SLABs AND FLOORS

Floor Slabs for houses with steel structure

Floor systems for steel-framed residential buildings are selected based on the loads, floor plan, and construction method. Slabs, sanitary floor systems, and structural steel floor systems can be combined within a single project.

Slab on Ground

A ground-floor solution that can incorporate insulation, a water or vapor barrier, radiant flooring, and interior finishes according to the specified configuration.

Sanitary Slab

An elevated design relative to the ground, suitable when the project requires a sanitary chamber or separation of the dwelling from the ground.

Ground Floor Slab with Steel Structure

Tubular profiles and auxiliary elements designed through structural analysis to form a load-bearing support between floors.

Slab with optional concrete pour

A concrete solution may be considered when the project requires it. The composition, reinforcement, and thicknesses must be specifically defined.

FACADES AND EXTERIOR FINISHES

Facade Finishes for houses with steel structure

Facade finishes for homes with metal frames can combine prefabricated wall systems with SATE, ventilated facades, and various exterior cladding materials. The final solution is tailored to the aesthetics and performance specifications defined in the project.

Sandwich panel

An industrialized solution that can serve as the building’s primary envelope. The thickness is selected based on thermal performance and the project specifications.

SATE

Exterior thermal insulation system applied to the building envelope, including additional insulation, mesh, mortar, and a final finish.

Ventilated facade

Exterior substructure and ventilated cladding. This can be achieved using materials such as aluminum composite, fiber cement, or Viroc, among other options.

Ceramic, stone, brick, wood, or stucco

The system allows you to explore traditional or contemporary exterior finishes to tailor the home’s final appearance to the architectural design.

Facade Junctions and Insulation Continuity

The facade must integrate the structure, exterior wall panels, insulation, cladding, and exterior finish. Window openings and corners require special attention.

Continuity of the enclosure at interior and exterior corners.
Top, bottom, and side joints of windows.
Coordination with subframes and rain gutters.
Continuity of insulation and treatment of thermal bridges.

COVERS

Roofs for houses with steel structure

Roofs for steel-frame houses are designed based on geometry, slopes, loads, and water drainage. The figure shows flat and sloped solutions, as well as configurations that integrate a steel substructure with sandwich panels.

Flat roof

This can be resolved by creating slopes and implementing project-specific waterproofing, while coordinating insulation, joints, and water drainage.

Single-slope Roof

Metal substructure designed to create a single slope and direct water towards the intended collection point.

Gable or multi-gable roof

Profiles and joints dimensioned to accommodate sloped eaves, ridges, and intersections as specified in the design.

The documented solution for the kit includes a substructure with 100 × 100 and 100 × 50 mm profiles, a 30 mm sandwich panel with flashing, trim pieces, and a concealed channel.

Technical Meetings on Steel Structures for Homes

This section is designed to incorporate the technical details provided. The drawings show how the structure, sandwich panels, insulation, facades, roofs, floor slabs, woodwork, and finishes are coordinated at key points in a home.

READING THE DETAILS

What Do These Design Details Achieve?

Thermal continuity

The details illustrate the relationship between sandwich panels, exterior insulation, air spaces, and interior finishes to minimize discontinuities in the building envelope.

Encounters with Holes

Jambs, lintels, sills, subframes, and drip edges must be coordinated with the carpentry, insulation, and exterior finish.

Water and Roof

Eaves, gutters, ridges, and roof junctions are key points for water drainage and protection.

Structural Work and Facade

The slab edge and wall starts combine structural elements, insulation, flooring, and associated barriers.

FREQUENTLY ASKED QUESTIONS

Questions About Construction Details of Steel Structures

We resolve common questions about foundations, facades, roofs, floor slabs, and technical joints in dwellings with steel structure.

What construction details does a house with steel structure need?

The key areas are the foundation and the base of the structure, floor slab joints, corners and openings in the facade, and roof edges. Every detail must coordinate the structure, insulation, exterior walls, waterproofing, and finishes.

How is the joint between the facade and the steel structure resolved?

The detail must coordinate the structural profile with the enclosure panel, the exterior or interior insulation, and the cladding. At corners and openings, special attention is given to the continuity of the building envelope layers.

What roof solutions can be used in a dwelling with steel structure?

The project may include flat or sloped roofs. The details must address roof slopes, roof panels, the substructure, eaves, gables, ridges, gutters, and connections to the exterior envelope.

What type of floor slab can a house with steel structure use?

The solution depends on the project. Options such as cast-in-place slabs, sanitary floor slabs, and structural steel floor systems can be considered, always sized according to loads, spans, and structural calculations.

Do the details shown apply to any home?

No. These are reference details used to explain StarModul construction solutions. The final composition, thicknesses, anchors, and joints must be adapted to the technical design, the structural analysis, and the performance requirements for each home.
