Why did Mr Gilzean decide it was time to replace his windows?

Mr Gilzean’s original windows had become increasingly inefficient over time. They were draughty, had poor thermal performance, and featured visible signs of wear, particularly rotting timber on both the internal and external sills.

While the windows were originally configured to resemble sliding sash, they were in fact designed with a larger fixed pane to the lower half with casement openers to the top. This meant they lacked functionality and the authentic appearance of true sash windows.

Improving comfort, reducing heat loss and updating the overall look of the property became key priorities for the upgrade.

Why were sliding sash windows the right choice?

Having seen CR Smith sliding sash windows in a neighbouring property, Mr Gilzean was impressed by both their appearance and quality. This gave him confidence that the same design would work well for his own home.

Given the traditional style of Edinburgh tenement properties, sliding sash windows are a natural fit. They reflect the original architectural intent while providing modern performance benefits.

The decision to install Lorimer sliding sash windows allowed Mr Gilzean to retain the heritage feel of the property while upgrading to a more efficient and practical solution.

How have the new windows transformed the appearance of the home?

The new Lorimer sliding sash windows have brought a noticeable transformation to the facade of the property. Where the previous windows appeared dated and inconsistent in design, the new installation introduces clean lines, balanced proportions and a more authentic finish.

Key traditional features, such as sash horns and ironmongery, enhance the overall look, helping the windows blend naturally with the character of the building.

The property’s bay windows in both the lounge and master bedroom are now defined, with the Lorimer sliding sash design complementing these architectural features perfectly. This creates a more cohesive and elegant external appearance, restoring the visual charm expected of a Victorian Edinburgh home.

How have the new sills and surround improved the interior space?

As part of the upgrade, Mr Gilzean opted for new white sills and surrounds, replacing the worn, deteriorating timber elements.

This has made a noticeable difference to the feel of the home internally. The clean white finish reflects natural light more effectively, helping rooms feel brighter, fresher and more spacious.

By carrying the white finish consistently across all windows, a cohesive look has been achieved throughout the property. This uniformity creates a sense of flow from room to room, enhancing the overall interior while maintaining a timeless and natural aesthetic.

How has the upgrade improved comfort and performance?

Replacing the old windows with modern double-glazed sliding sash units made a significant difference to the home’s comfort. Draughts have been eliminated, heat is retained more effectively, and overall energy efficiency has improved.

Mr Gilzean commented on the improved comfort within the home, stating;

“We are very happy with our new windows and have noticed a big difference in comfort.”

How do Lorimer sliding sash windows enhance traditional homes?

By combining traditional detailing, such as sash horns and authentic hardware, with advanced glazing and insulation, Lorimer windows provide the best of both worlds. Homeowners can maintain the heritage appearance of their property while enjoying improved warmth and low-maintenance living.
