ANDROULAKIS, as a pioneering company in the field, uses the best raw materials, as only it knows, uncompromisingly!!! Our priority is the initial stage of construction, the load-bearing structure – frame, which determines the building’s stability, thermal insulation, and moisture insulation, contributing to the longevity of the building. Therefore, the best choice for the construction of the load-bearing structure – frame could only be the use of SWEDISH & SCANDINAVIAN TIMBER.
Application: Use of Swedish timber as the main structural material for the construction of the load-bearing structure – frame in prefabricated houses.
ADVANTAGES:
- Strength category C24, high mechanical strength, according to EN 338. The category C index indicates static bending.
- Kiln-dried, with the wood undergoing drying that imparts significant advantages. The drying is uniform and with a slow moisture exit rate. Remaining moisture 12-15% to maintain elasticity.
- VACUUM IMPREGNATION: Introduction of wood with natural pest control without chemical impregnation. The impregnation is done using the full-cell method (vacuum-pressure-vacuum). Wood protection is for defense against decay fungi, insects, improvement of dimensional stability, improvement of natural and mechanical properties, and increased fire resistance.
- Planed, meaning it has perfectly flat surfaces, which, combined with factory connections, achieve perfect assembly and zero joints in the frame section.
- Thermal insulation: Wood, being a natural material, acts as a perfect natural regulator of temperature and humidity inside the house, providing natural thermal insulation properties superior to any other building material.
- High seismic resistance: Homes with a wooden load-bearing structure-frame exhibit high seismic resistance due to wood’s advantages as a material, its high mechanical strength, density, elasticity, allowing the absorption of seismic loads in the connections of the frame elements. Additionally, wood retains seismic memory, enduring continuous seismic vibrations with various accelerations (g: 0.5 to 0.9), making the residence fully seismic-resistant.
APPLICATION: Drywall screw technology with screws and TORX plugs from the leading German company Wurth.
ADVANTAGES:
- The use of screws prevents loosening of the connection over time.
- Our scientific department developed a connection to enhance the load-bearing structure and create a fully seismic-resistant construction resistant to high stresses.
BREATHABLE ASPHALT MEMBRANE
- It is a special sealing membrane, partially vapor-permeable, with a unique combination of double polypropylene fabric and asphalt.
Application: Roof and wall sealing.
ADVANTAGES:
- Provides complete waterproofing.
- Has high mechanical strength, does not crack or puncture.
- Resists high temperatures.
- Prevents the accumulation of water vapor.
- Complies with EN 1110 EN12310 standards.
It is a material produced from compact polystyrene beads.
Application: External thermal insulation. EPS expanded polystyrene products are applied to a building from the foundation to the roof.
ADVANTAGES:
- Has excellent thermal insulation properties.
- Acoustic properties contribute to both airborne and impact sound insulation.
- It is rigid.
- Non-toxic, produced without chemical additives.
- Not affected by moisture, has low water vapor diffusion resistance, and has the ability to “breathe,” preventing condensation.
- Has structural stability and does not decompose. The stability of EPS is not affected over time, with a long service life.
- Is self-extinguishing, does not propagate flames. Produced for building use as self-extinguishing (self-extinguishing SE) as it contains a flame retardant in its mass.
- Is fully recyclable and environmentally friendly.
- Produced in accordance with European standard EN 13163.

“Energy-efficient Glass” has the ability to impede heat emission from the warmer to the colder side, known as low-emissivity (Low-E) glass. This property helps retain indoor warmth during winter and keeps external heat outside during summer, saving energy for heating or cooling. The “Energy-efficient Glass” function operates under all weather conditions (cloudy or sunny), at all times (day and night), and throughout all seasons (winter – summer).
