Energy Efficient Double Glazing, Croydon

The broken-up Liniar profile makes our uPVC double glazing extremely heat-efficient. You can expect a Windows Energy Rating of ‘A+’ quite easily.

The reason why our double glazed windows and double glazed doors profiles are so effective is that the chambers in the profile trap warm air inside and stop convection currents from forming. This layer of still air acts as insulation, locking the heat inside the room.

Secondly, our efficient installations includes weather seals and bubble-gaskets that prevent draughts and rainwater seepage.

These two factors combine to give you Croydon double glazing that is warm and dry even in the most inclement of British weather.
