  • “I’m worried about draughts and poor airtightness after installation.” 
  • “I want new sliding doors, but don’t know if the opening can be created safely.”

If this sounds familiar, you’re not alone.

High-Performance Window Installation Systems

We don’t just “fit windows.”
We install them using proven thermal and airtightness systems that dramatically improve performance. 

 

  1. 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 

 

  1. 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.
