How to Correctly Install Salamander Windows in Bucharest? Professional Guide 2026

Why Salamander Window Installation Matters So Much

You have chosen Salamander bluEvolution 82 or 92 profiles — products with Uf down to 0.9 W/(m²K) and 47 dB acoustic insulation. But the technical performance of the profile means nothing if installation is done incorrectly. Poor installation generates: thermal bridges at the frame-masonry joint, water and air infiltration, condensation on window sills, and over time, frame deformation. This guide shows you exactly what professional Salamander window installation in Bucharest and Ilfov involves.

Step 1 — Survey and Design

Professional installation always starts with on-site measurements, not approximate dimensions. The technician measures the existing opening (masonry) and calculates frame dimensions considering:

• Wall type (aerated concrete, brick, concrete, sandwich panel)
• Plaster or thermal insulation layer thickness
• Chosen installation type — direct in wall or on Blaugelb preframe
• Need for interior (PVC or aluminium) and exterior (aluminium) window sills

Blaugelb Triotherm Plus Preframes — The nZEB Standard

For new constructions and nZEB (Nearly Zero Energy Buildings) renovations, Neofort BIZ uses Blaugelb Triotherm Plus preframes. The preframe is installed before the window itself and creates a continuous thermal barrier between frame and masonry, eliminating the thermal bridge at the window perimeter — the main cause of condensation on sills in older dwellings.

Step 2 — Removing Old Windows

Removal is carried out with professional suction cups for handling large glazing units, without damaging masonry or interior finishes. Remnants of polyurethane foam, sealant or old profiles are completely removed from the opening before installing the new windows.

Step 3 — Installation According to nZEB Standard

Professional nZEB installation follows the RAL standard (German Quality Association for Windows):

Interior zone — vapour sealing:

• Interior vapour barrier tape (PE film or adhesive butyl tape) — prevents moisture migration from interior toward the frame-masonry joint

Middle zone — fixing and stabilising:

• Metal mounting anchors at max. 70 cm intervals
• Plastic packers and sub-packers (not wood!) for supporting the weight of the glazing pack
• Semi-open cell polyurethane foam in the remaining space

Exterior zone — water sealing:

• Pre-compressed butyl band (e.g. Illbruck TP600, Soudal Compriband) — expands after installation and seals the external perimeter against water and wind
• This replaces classic sealants that crack over time and allow infiltrations

Step 4 — Hardware Adjustment

After installation, Roto NT or Winkhaus hardware must be precisely adjusted in all 3 axes (vertical, horizontal, compression). Incorrectly adjusted hardware causes: sashes rubbing against the frame, uneven gasket compression, difficult closing after a few months.

Step 5 — Window Sill and Finishing Installation

• Interior PVC window sills — fixed with expanding foam in the frame and siliconed around the perimeter
• Exterior aluminium window sills — with drip profile and outward slope (min. 5°)
• Exterior siliconing with UV-resistant neutral silicone, colour matched to the profile

Common Installation Mistakes That Cost

❌ Polyurethane foam instead of pre-compressed band at exterior — cracks in 2–3 years, allows infiltrations❌ Wooden packers under frame — rot, affect levelling over time❌ No preframe on nZEB constructions — thermal bridge eliminates 40–60% of energy savings❌ Incorrect frame sizing vs actual opening — large gaps filled with too much foam❌ Hardware not adjusted after installation — premature wear, closing difficulties

How to Choose a Serious Window Installation Company in Bucharest

• ✅ The company always comes for on-site measurements (does not accept orders based on dimensions provided by the client)✅ Uses pre-compressed bands (ask explicitly — not foam at exterior)✅ Offers a written contract with complete technical specifications✅ Minimum 5-year warranty on product and workmanship✅ Own installation teams, not subcontractors✅ Blaugelb preframes or equivalent for nZEB projects
