Everglaze Manufacturing
We are happy to share that Everglaze Ltd now makes all our very own UPVC windows, UPVC and composite doors, and we even manufacture our double glazed units in-house.
This important step helps us keep full control over quality, design, and delivery times. It also lets us pass cost savings directly to our customers.
Superior Quality Control
By bringing manufacturing in-house, we personally oversee every aspect of production from raw materials to finished product.
Each window and door passes through multiple quality checkpoints before reaching your home, ensuring excellence at every stage.
Customisation Without Compromise
Our dedicated manufacturing facility enables us to offer truly bespoke solutions.
If you need custom sizes, special designs, or unique hardware, our team can help. We can create windows and doors that fit your vision perfectly.
Reduced Lead Times
Eliminating third-party suppliers means we can significantly reduce waiting times.
Your custom windows and doors go straight from our factory to your home. This makes the process easier from order to installation.
Environmental Responsibility
Our local manufacturing operation reduces transportation emissions and allows us to implement eco-friendly production methods.
We carefully manage waste materials and utilize energy-efficient equipment throughout our facility.
Double Glazing
Our precision-engineered sealed units deliver outstanding thermal efficiency through advanced design and construction.
We offer various cavity sizes to suit different requirements, incorporating optional low-E coatings for enhanced performance. Each unit features warm edge spacer technology and argon gas filling, ensuring superior insulation properties and long-term performance.
Triple Glazing
For ultimate thermal performance, our triple glazing units achieve exceptional U-values as low as 0.8 W/m²K. These units provide enhanced sound insulation and increased security protection, making them particularly suitable for exposed locations or areas where noise reduction is a priority.
The additional glass pane creates an extra barrier against heat loss and external noise, ensuring your home remains comfortable year-round.
Acoustic Glass
Our specialised acoustic glass utilizes advanced laminated construction techniques to significantly reduce external noise by up to 42dB. This makes it an ideal solution for properties near busy roads or in urban environments.
The acoustic properties can be combined with thermal efficiency features, offering a comprehensive solution for both noise reduction and energy conservation. Each unit is carefully engineered to provide optimal sound insulation without compromising on light transmission or visual clarity.
Bespoke Glass Designs
We offer an extensive range of decorative options to enhance the aesthetic appeal of your windows and doors. From traditional leaded designs and Georgian bars to contemporary privacy patterns and sandblasted finishes, our in-house capabilities allow us to create truly unique glass solutions.
We can produce custom etched glass, incorporate colored glass options, and manufacture specialist safety glass to meet specific requirements. Each bespoke design is carefully crafted to complement your property’s style while maintaining all necessary safety and performance standards.
