People spend ten grand on new windows.
November hits. The mornings get freezing. Homeowners look outside. The external glass is covered in thick water.
They panic. They call the fitter. They accuse them of fitting blown windows.
They are wrong.
The Heat Leak
Old double glazing is terrible.
The heat from your radiators goes straight through the inner pane. It travels through the gap. It warms up the outside pane of glass.
Warm glass does not attract morning dew. The outside glass stays completely dry. You are just paying to heat the street outside your house.
The Heat Trap
Modern A-rated windows stop the heat transfer completely.
We fit units with Low-E glass coatings. We use warm-edge spacer bars inside the frame. The heat hits the inner pane and bounces straight back into the living room.
Zero heat reaches the outside pane.
The Cold Glass
The external glass stays freezing cold all night.
The damp morning air hits that cold glass. It turns into water. The condensation sits directly on the outside of the window.
It proves the unit is working. The heat is locked solid inside the property.
The Bill Drop
Do not panic about exterior condensation.
It usually burns off by mid-morning when the sun hits it. It simply means your heating bills are dropping. The glass is doing the exact job you paid for.
Come down to 78 Alma Road. We have the A-rated glass units cut in half on the trade counter. Look at the internal spacer bars yourself or give us a call on 01202 533126.
