Thickness matters, but material properties, continuity and correct installation determine how the insulation layer performs as a system.
Why this matters for properties in Paphos
Different insulation materials do not provide the same thermal resistance at the same thickness. The roof build-up, available height, thresholds, parapets and drainage can also constrain the design.
What to inspect before deciding
Ask for the material type, declared thermal performance and proposed thickness. Check how the layer remains continuous around penetrations and how changes in level affect drainage.
A practical way to plan the work
Compare proposals using the complete build-up rather than thickness alone. Where regulatory compliance or technical design is required, use appropriately qualified advice for the specific property.
Common mistake to avoid
Choosing the thickest option without checking details can create problems at doors, outlets and edges. Gaps or poorly treated junctions can also undermine an otherwise good specification.
