Rosewood Triangle Gable Window Installation in Shaftesbury, Dorset

At Goldhill Glazing, we recently completed the installation of a bespoke rosewood triangular gable window at a property in Shaftesbury, Dorset.

Unlike standard rectangular windows, shaped windows require exceptional attention to detail during surveying and manufacturing. Every angle, measurement and detail must be accurate to ensure the finished frame fits perfectly within the existing opening.

For this project, the homeowner wanted to replace an ageing shaped window with a modern, energy-efficient alternative that would retain the property’s traditional appearance while dramatically improving insulation, durability and long-term performance.

The finished result is a stunning rosewood timber-effect uPVC gable window that complements the natural slate roof beautifully and enhances the overall character of the property.

Why Replace a Triangular Gable Window?

Many homeowners assume unusual shaped windows are difficult or impossible to replace.

In reality, modern manufacturing allows bespoke windows to be produced to the exact dimensions of the existing opening, providing all the benefits of modern double glazing without changing the character of the property.

The original window had reached the stage where replacing it would provide significant improvements in both performance and appearance.

The homeowner wanted to benefit from:

Better insulation
Lower heating bills
Improved weather protection
Reduced maintenance
Increased energy efficiency
Modern glazing technology
A long-lasting replacement window

Replacing a bespoke shaped window is one of the best ways to improve comfort while preserving the unique architectural features of a home.

Accurate Surveying Makes All the Difference

Every bespoke window installation begins with a detailed survey.

Unlike standard casement windows, triangular and apex windows cannot simply be measured by width and height alone.

Every angle has to be checked carefully before manufacturing begins.

During our survey we measured:

Overall width
Overall height
Apex angle
Roof pitch
Existing frame position
Internal reveals
External finishes
Structural opening
Flashing details

This careful approach ensures the finished window fits precisely, seals correctly and performs exactly as intended.

At Goldhill Glazing, we believe accurate surveying is one of the most important parts of every installation.

Manufactured Specifically for This Property

Every shaped frame we install is completely bespoke.

This rosewood triangular window was manufactured specifically for this property in Shaftesbury using the measurements taken during our survey.

The result is a perfectly fitting window that follows the existing roofline while providing modern levels of thermal performance and weather resistance.

Unlike mass-produced standard windows, shaped frames require specialist manufacturing to achieve clean, accurate angles and a flawless finish.

Professional Installation

Installing a shaped window requires patience, experience and precision.

After carefully removing the existing frame, we prepared the opening before positioning the new bespoke window.

The installation included:

Accurate packing
Precision levelling
Secure mechanical fixing
Full perimeter insulation
Internal sealing
External weatherproof sealing
Final operational checks
Thorough finishing throughout

Extra care was taken around the lead flashing and slate roof to ensure a neat weatherproof finish while preserving the property’s appearance.

Modern Double Glazing with Traditional Character

Although this window has the appearance of traditional timber, it incorporates all the benefits of modern glazing technology.

Each sealed unit includes:

Low-E Glass

Low-emissivity glass reflects heat back into the room, helping reduce heat loss during colder months while allowing natural daylight to enter the property.

Argon Gas Filled Unit

Argon gas improves thermal insulation compared with ordinary air, increasing the overall efficiency of the sealed unit.

Warm Edge Spacer Bars

Warm edge technology reduces heat transfer around the perimeter of the glass while helping minimise condensation.

Together these features help create a warmer, more energy-efficient home all year round.

Outstanding thermal efficiency
