High-performance insulation for space-constrained construction projects
Designed for exceptional insulation at minimal thickness.
Increasing insulation thickness is often the simplest way to improve thermal performance. It is rarely the simplest way to complete a project.
In renovation, refurbishment and space-sensitive construction, additional insulation thickness can create challenges around thresholds, parapets, rooflights, floor levels, façades and usable internal space.
Turvac helps architects, specifiers and contractors achieve demanding thermal performance where conventional insulation thickness creates practical or dimensional constraints.
More performance. Less space. Fewer compromises.
- Reduce insulation thickness while achieving demanding thermal performance.
- Preserve valuable usable space in walls, floors and compact building designs.
- Simplify challenging construction details around thresholds, rooflights, doors and parapets.
- Improve building energy efficiency by minimising heat loss through the building envelope.
When conventional insulation creates construction challenges
Increasing insulation thickness may be technically straightforward on paper, but much harder to accommodate in practice.
In renovation and space-sensitive projects, additional build-up can trigger modifications to roof edges, parapets, windows, doors, rooflights, smoke vents, gutters, thresholds and internal finishes. It can also reduce usable floor area or conflict with existing construction heights.
Turvac VIPs provide high thermal performance within a slim profile, giving designers and contractors another option when available space becomes a critical project constraint.
Where thermal performance meets real-world construction constraints
Turvac VIPs can be engineered around specific dimensions and construction requirements, making it particularly suited to applications where space efficiency and repeatable building systems are essential.
Terrace and flat roof renovations
Improve thermal performance within existing construction heights. Turvac Si VIP helps minimise modifications to parapets, rooflights, gutters, windows and doors while preserving existing detailing.
Roof terraces and balconies
Achieve high thermal performance with minimal floor build-up, helping maintain low thresholds, accessibility and continuity between interior and exterior floor levels.
Interior insulation where every square metre counts
Improve thermal performance with minimal wall build-up, preserving valuable living and usable floor space.
Typical applications: Apartment renovations · Heritage buildings · Hotels · Student accommodation · Healthcare facilities · High-value residential developments
Modular construction and off-site manufacturing
Reduce wall, roof and floor build-ups to maximise usable interior space within fixed external dimensions — ideal for modular, prefabricated and compact construction.
Doors and gates
Enhancing thermal efficiency while maintaining slim, lightweight door and gate constructions.
