The Indoor Frosting Shock
Water streams down the internal metal face of cheap aluminium window frames all winter.
Some budget window systems get so cold that actual ice crystals form right on the inside profile. Homeowners constantly blame their heating settings or bedroom ventilation for the moisture. This diagnosis is wrong. The real structural fault sits deep inside the manufacturing of the metal frame itself.
The Missing Thermal Barrier
Raw aluminium conducts thermal energy with massive speed.
Budget windows imported online use a solid, continuous piece of extruded metal running from the outside world straight into your living room. This design creates an unrestricted thermal bridge. Freezing winter air chills the outside frame, instantly transferring that exact sub-zero temperature directly onto the internal metal face inside your warm house.
The Polyamide Solution
High-quality trade systems eliminate this freezing transfer using advanced separation engineering.
Quality profiles require an aluminium window condensation thermal break. Manufacturers split the internal and external aluminium sections completely, joining them back together using a high-density polyamide nylon barrier. This structural plastic strip blocks the cold pathway dead, keeping the internal frame near room temperature.
Spotting Low-Grade Imports
Cheap internet suppliers cut factory costs by skipping this vital internal insulation layer.
They sell thin, non-broken commercial-grade shopfront sections re-badged for domestic houses. These inferior frames cause heavy pooling water, rot internal plaster lines, and ruin expensive curtains within months of installation. Always demand a full section drawing to verify the presence of a thick polyamide break.
