Your original windows are part of what makes your home special. Improving their performance can also help make your rooms more comfortable, through colder winters and warmer summers.
At Vacuum Window Restoration, we restore and upgrade existing timber sash and casement windows. LandVac vacuum glazing helps reduce heat loss in colder weather and, with an appropriate solar-control specification, can also reduce unwanted heat from sunlight during warmer months.
A bright, sunny room can be a pleasure—until it becomes uncomfortably warm. Sunlight passing through glazing brings energy into your home, warming floors, furniture and other surfaces. This is known as solar heat gain.
The amount of solar heat entering through a window depends partly on the glass and its coatings. LandVac is available in different specifications, including solar-control options designed to reduce that heat gain.
Choosing suitable glazing can help make sunny rooms more comfortable. The result will depend on your existing windows, the specification selected and the conditions in your home. Ventilation and shading remain important, particularly during prolonged hot weather.
During colder months, the priority is keeping warmth inside.
LandVac uses a very thin vacuum gap between two panes of glass to reduce heat transfer. This improves insulation through the glazing and helps limit the heat escaping from a warm room into colder outdoor air.
Combined with careful timber repairs, window overhaul and appropriate draught-proofing, vacuum glazing can improve comfort while retaining the character of your existing windows.
The best choice depends on how each room is used and how much sunlight it receives.
A room exposed to strong afternoon sun may have different needs from a shaded room where maximising natural light is the priority. Stronger solar control can reduce the amount of daylight and useful winter sunshine entering a room, so the choice should balance comfort throughout the year.
When discussing your windows, we can consider:
We can then discuss the available glazing options and explain the specification proposed for your property.
Improving comfort does not always mean replacing the whole window.
Where existing timber windows are suitable, vacuum glazing can be fitted as part of a restoration programme. Repairs, careful overhaul and discreet draught-proofing can help preserve original joinery while improving its performance.
Our work focuses on traditional sash and casement windows, with particular care for the appearance and character of period properties. For listed buildings and properties subject to heritage restrictions, any necessary consents should be checked before alterations.
Suitable solar-control glazing can reduce heat entering through the glass, but it cannot guarantee that a room will stay cool. Window size and orientation, shading, ventilation and heat generated inside the building all affect the temperature.
No. Insulation and solar control are different properties. The vacuum gap helps reduce heat transfer, while the glazing specification and coatings determine how much solar energy enters. We can explain the options proposed for your windows.
It depends on the specification. Stronger solar-control options can reduce visible light transmission and may affect the appearance of the glass. We can discuss that balance before you make a decision.
In many cases, suitable timber windows can be restored and upgraded. An assessment is needed to establish their condition and whether they can accommodate the proposed glazing.
Whether your rooms feel chilly in winter, become too warm in summer, or both, we can help you explore suitable improvements to your existing timber windows.
