Essential Materials for New Construction - Guide

Introduction to New Construction: What You Need to Know

Starting a new construction is an exciting undertaking, but it comes with many decisions and challenges. One of the most critical steps is choosing the right materials, as these determine the durability, safety, energy efficiency and overall quality of the building. In this comprehensive guide, we will examine the necessary materials for every new construction, from foundation to finish, providing practical tips to make the right choices.

1. Foundations and Frame Materials

The foundation and the skeleton form the backbone of every building. The choice of materials here is crucial for the static adequacy and longevity of the construction.

Concrete (Concrete)

Concrete is the most widely used foundation material. It consists of cement, aggregates (sand, gravel) and water. The basic types of concrete include:

• Reinforced concrete:
  It is reinforced with steel bars (reinforcement) to withstand tensile forces.
  
• Ready Concrete:
  It is delivered by a factory with specific specifications, ensuring homogeneity.
  
• Lightweight concrete:
  It is used for lighter construction or insulation.
  

Tip:
For foundation, prefer C20 / 25 or higher, depending on static studies.

Certification

Steel is essential for reinforcing concrete. Rods of various diameters (e.g. 8mm, 10mm, 12mm) and reinforcement grids are used. The quality of steel is determined by its tensile strength (e.g. B500C).

Wood for Xylotyping

Formats are molds that hold the damp concrete until it hardens. The timber must be durable and reusable. Usually sea plywood or plywood is used.

2. Masonry Materials

The walls of a construction can be load-bearing or dividing. The materials vary depending on the needs.

Bricks

Bricks are one of the most traditional materials. They are available in various types:

• Perforated bricks:
  They have holes to reduce weight and improve insulation.
  
• Payment Terms:
  More durable, used for bearing walls.
  
• Fire bricks:
  They can withstand high temperatures, suitable for fireplaces.
  

Cement blocks (CMU)

Concrete blocks are large, economical building blocks. They are widely used for basements, retaining walls and buildings. They can be empty or full, with good thermal insulation capacity if combined with insulation.

Plasterboard

Drywall is used for internal partition walls and cladding. It is lightweight, easy to install and offers good soundproofing if mounted with insulating material.

3. Insulation Materials

Insulation is critical for energy efficiency and comfort. Basic insulation materials include:

Stone wool

Stone wool is a fibrous material made of natural rocks. It provides thermal insulation, sound insulation and is non-combustible.

Expanded Polystyrene (EPS)

Also known as Styrofoam, it is lightweight, economical and has good thermal insulation capacity. It is used in facades, floors and roofs.

Extruded Polystyrene (XPS)

More resistant to moisture than EPS, suitable for basements and foundations.

Polyurethane (PUR / PIR)

It has a very low thermal conductivity coefficient, so it requires a smaller thickness for the same insulation.

Tip:
Choose insulation based on the climate of the area and the requirements of the building. The correct application is as important as the material.

4. Sealing Materials

Protection from moisture is essential to avoid damage.

Bituminous membranes

They are used for waterproofing roofs and foundations. They are durable and offer full protection.

Fluid Membranes

They are applied in liquid form and create a continuous, seamless membrane.

Cement Sealants

They are used in tanks, pools and basements, as they can be applied to wet surfaces.

5. Mortars and Binding Materials

Mortars are mixtures of cement, sand and water, used for building, plastering and grouting.

Cement

Cement is the basic binder. Types include:

• Portland Cement (CEM I):
  For general uses.
  
• Composite cement (CEM II):
  It contains additives, more ecological.
  
• White cement:
  For aesthetic applications.
  

Lime

Lime is used in traditional mortars, offering flexibility and transpiration.

Gypsum

It is used for interior plasters and decorative elements.

6. Coatings and ΦSealing materials

Finishing materials determine the appearance and strength of surfaces.

Tiles

Ceramics, porcelain or marble, for floors and walls. Choose according to the area (bathroom, kitchen, outdoor areas).

Wooden Floors

Parquet or timber for a warm atmosphere.

Paints and Varnishes

Interior and exterior paints, based on water or solvents. Prefer ecological paints with low volatile organic compounds (VOCs).

Plates

Decorative plasters with various textures (grated, Venetian).

7. Frames Materials

Frames (doors, windows) affect energy efficiency and safety.

Aluminium

Durable, lightweight, with good thermal insulation if it has a thermal break.

PVC

Economical, with excellent insulation and low maintenance.

Wooden

Φnatural material with high aesthetics, but requires maintenance.

Glazing

Double or triple energy glazing with low emission coatings to reduce heat loss.

8. Electrical and Hydraulic Materials

Although less obvious, they are necessary.

Cables and Pipes

Copper for electrical installations, PVC or polypropylene for plumbing.

Shunt boxes, Sockets, Switches

Choose certified materials for safety.

Categories

Washbasins, basins, batteries, water consumption.

Conclusion

Choosing the right materials is fundamental to the success of your construction. Invest in quality materials that meet the specifications and work with experienced professionals. Remember that durability, energy efficiency and safety are more important than the initial cost. With careful planning and the right choices, your building will be beautiful, functional and long-lasting.
