There are many aspects of a building that affect its thermal performance. Windows are one of the largest contributors of heat gain or loss and this is determined by the combined effect of the glass, frame and seals.

By installing double glazed windows you will create a comfortable and sustainable environment all year round and save a fortune on energy bills.

Windows and doors with an optical grade acrylic glazing is up to six times more thermally efficient than glass on it own.

PVC sub-frame creates a thermal break from your existing window frame while our airtight magnetic seals eliminate draughts.

These features provide a more constant and comfortable room temperature. This means that you will sleep better at night and be more productive during the day.


Condensation can be a major contributor to allergies in a home.

The installation of double glazed windows will reduce condensation appearing on windows. 

This will protect the health of your family as well as protecting window furnishings and sills from mould. Double glazing can be retrofitted and is one of the quickest and most convenient ways to upgrade your existing windows thermal performance and achieve significant energy savings at the same time.
