Insulation Systems: Complete Solutions for Every Building

Comparison of building thermal insulation systems

Choosing the right insulation system is the most critical decision for your home's energy protection. Here we are not talking about individual materials, but about complete technical application solutions - from the hugely popular external thermal insulation (ETICS) to internal insulation and modern ventilated facades.

Discover which system suits your needs (renovation or new build), compare advantages, and see how proper application eliminates thermal losses and reduces heating and cooling costs.

External Insulation (ETICS)

Also known as the "thermal façade", it is the top choice for energy upgrading existing (and new) buildings in Greece. It wraps the building like a protective envelope, eliminating thermal bridges and protecting structural elements from weather conditions.

What is the ETICS system and what are its advantages?

Complete guide to how the External Thermal Insulation Composite System works, its application layers and why it is considered the ultimate energy-saving solution.

How does insulation thickness affect final performance?

Is upgrading from 5cm to 10cm worth it? See with examples in the 10x10 Model how board thickness translates into real kWh savings.

The 7 most common contractor mistakes in envelope installation

From incorrect mesh embedding to poor adhesion. Learn what to watch for to avoid cracks and future delamination.

External insulation cost per sq.m.

How much will the thermal façade really cost you? Detailed breakdown of cost per square metre to help you budget your project correctly.

How external insulation protects the structural frame

The thermal façade doesn't just cut bills - it saves the concrete and reinforcement from contraction-expansion cycles and corrosion.

Internal Insulation

When exterior intervention is impossible - e.g. in listed buildings, apartment blocks or individual flats - internal insulation provides the solution. Learn how to insulate from the inside correctly, avoiding the nightmare of damp and mould.

When do we choose internal over external insulation?

All the constraints (legal, practical and financial) that make internal insulation the only viable option for your renovation.

Insulation tiles (polystyrene/XPS) for direct bonding

The DIYer's favourite: lightweight, thin insulation tiles bonded directly to the wall for quick and affordable improvements.

Loss of usable space: How many sq.m. do we lose?

Calculate the usable space you sacrifice inside your home, depending on the system thickness you choose.

Insulation behind radiators: Is it worth it?

A small intervention with big returns. How reflective membranes direct radiator heat into the room instead of the external wall.

Cavity Wall & Core

The classic Greek construction method enters a new era. We examine how the cavity (the core) between bricks is insulated, either during original construction or retrospectively in existing buildings.

Cavity wall insulation: How does it work?

The basic principles of double-leaf masonry and the critical role of the insulation material trapped at the centre of the wall.

Insufflation Method: Insulating existing cavities

The ultimate solution for old houses with air gaps in the walls. How we fill the gap with insulation without demolition or mess.

Instructions and best practices for building new double walls with classic extruded polystyrene boards.

Moisture management in cavity walls (Weep holes)

How we ensure moisture trapped in the cavity can escape, protecting the insulation from possible decay.

Thermal bridges in cavity walls: Breaking at ring beams

The biggest weakness of double walls is uninsulated beams, columns and ring beams. Learn how to close these energy gaps.

Ventilated Facades & Special Systems

High architecture meets peak energy performance. Ventilated facades and specialised coatings are cutting-edge solutions offering unparalleled breathability and aesthetics, especially for large or commercial buildings.
