Insulate Windows

Stand next to a sunny west-facing window at four o'clock in August and you can feel the heat radiating from the glass. In January the same window turns into a cold surface that chills the room and gathers condensation. Window insulation tackles both problems by reducing how much heat passes through the glass, the frame and the wall around it.

It is a broader job than simply sealing cracks. A specialist looks at the whole window as a thermal system and targets its weakest points, which often include the roller shutter box above the frame and the uninsulated gap hidden behind the trims. FixNow lets you post your concerns and receive offers from local professionals across Cyprus, from Nicosia's hot inland summers to breezy coastal homes in Paphos.

Where windows lose and gain heat

• The glass: single glazing and older double glazing let heat through easily, especially without a low-e or solar-control coating.
• The frame: aluminium without a thermal break conducts heat directly between inside and outside.
• The installation gap: the space between frame and wall is often left partly empty or filled with crumbling foam.
• Roller shutter boxes: hollow boxes above the window are frequently uninsulated and leak air.
• Reveals and lintels: concrete around the opening can form a cold bridge, leading to damp and mould.

Insulation upgrades a professional can carry out

• Glazing unit upgrade: replacing single panes or tired double-glazed units with modern insulated glass that fits the existing frame, where the frame allows.
• Perimeter insulation: removing trims, clearing old filler and injecting suitable insulating foam, then sealing it from weather and light.
• Shutter box insulation: lining the box with insulation boards and fitting brushes or seals around the strap and slot.
• Secondary glazing: adding an inner pane where the main window cannot be changed, for example in listed or rented properties.
• Reveal treatment: applying insulating board or thermal plaster to cold reveals before redecorating.

Choosing the right approach for your home

If your frames are sound but the glass is old, a glazing upgrade often gives the biggest improvement for the money. If the frames themselves are poor, such as old non-thermally broken aluminium, insulation work can help, but at some point full replacement becomes the better investment. A professional should be able to explain where your windows are losing performance and which measures make sense, rather than proposing everything at once.

Keep in mind that external shading, such as shutters, awnings and solar film, also plays a big role in Cyprus summers. You can combine those with insulation for the best result.
