High-Performance Window Installation Systems
We don’t just “fit windows.”
We install them using proven thermal and airtightness systems that dramatically improve performance.
- TriothermBlaugelb – Thermal Supports for Advanced Window Positioning
Triotherm is used when shifting windows out into the insulation layer to eliminate thermal bridges. This method is ideal for:
- Deep retrofits
- EnerPHit upgrades
- Passive House-level installations
- Homes with external insulation
Benefits:
- Excellent thermal performance
- Strong structural support
- Reduced risk of cold spots and mould
- Perfect alignment with modern insulation standards
- Phonotherm(RG550) – The Ideal Insulation Board for Door Thresholds
Phonotherm is a stable, load-bearing insulation board used to minimise thermal bridging at:
- Door thresholds
- Window sills
- Critical junctions
- Low-energy retrofit installations
Why we use it:
- Very high compressive strength
- Excellent thermal insulation
- Moisture-resistant and dimensionally stable
- Perfect for modern door and window details
It significantly reduces heat loss at critical junctions where traditional materials would create cold bridging.
