Old Insulation Renewal in Umluj
Azl delivers old insulation renewal in Umluj with a method that starts with diagnosis, selects the system that suits the city's conditions, and ends with testing and a written warranty. Renewing old insulation starts with diagnosing the existing system: measuring trapped moisture, testing the old layer's adhesion, and checking joints, slopes and drains.

A general city profile for technical planning; conditions vary between districts and are confirmed during inspection.
Our technical recommendations for old insulation renewal in Umluj
Thermal insulation first
Umluj has hot summers, so roof thermal insulation should be a core part of the solution rather than an optional extra, with a heat-reflective top layer to cut the cooling load on upper floors.
Coastal humidity
High humidity in Umluj affects how materials cure and bond, so we schedule application in the least humid hours, measure surface moisture before starting, and choose materials that withstand the coastal environment and protect rebar from corrosion.
Materials we choose from
- New protective coat for foam: Acrylic, silicone, polyurethane or polyurea, renewed periodically to protect the foam from UV.
- Compatible liquid polyurethane coating: To overcoat sound existing systems after compatibility and adhesion testing.
- New bituminous membrane: After removing detached or saturated old membrane, with slopes and upstands corrected.
- Foam sprayed over sound foam: Raises thermal resistance when the old layer is sound and dry.
- Reinforcing tapes and spot-repair materials: For joints, corners and drains before the new layer is applied.
Work stages
- Inspect the roof and the ceiling below and locate leak points
- Run a thermal scan and moisture readings to map wet areas
- Take core cuts to identify the layers, their thickness and condition
- Test adhesion and compatibility, then decide overcoat or removal for each area
- Remove damaged and saturated areas and correct slopes and drains
- Apply the new system, flood-test, and document the condition before and after
Comparing the available systems
| System | Function | Strength | Needs | Est. SAR/m² |
|---|---|---|---|---|
| Spray polyurea | Waterproof + mechanical/chemical protection | Cures in seconds, highly flexible | Specialist rigs and precise surface prep | 70–160 |
| Reflective elastomeric acrylic | Waterproof + reflective | Light, quick, ideal for maintenance | Periodic recoating and a sound substrate | 18–40 |
| Spray polyurethane foam | Thermal + waterproof | Seamless layer covering details | UV topcoat and periodic checks | 30–55 |
| Bituminous membrane rolls | Waterproofing | Durable, factory-controlled thickness | Careful laps and protection or mineral-faced rolls | 18–40 |
Indicative ranges before VAT. A system's real life depends on the product, workmanship and maintenance, so we state it in the written quote and warranty rather than a generic table.
Warranty and compliance
You receive a written warranty whose period depends on the insulation type and surface condition, with a handover report documenting materials and tests (flood, adhesion, thickness).
