Energy Efficient Windows and Custom Glazing Services in UK
We specialise in providing high-quality, energy-efficient window solutions for residential and commercial properties across the UK. From new builds to heritage properties, we offer a wide range of services designed to improve thermal performance, increase security, and reduce energy bills. Whether you need double-glazed windows or sash restoration, we have the expertise to meet your needs. Below, we detail each service that we provide, offering insight into the technical aspects and benefits of our energy-efficient solutions
Energy Assessment and Consultation
Before we begin the installation process, we carry out a full energy assessment of your property. This step involves:
- Thermal Imaging: Identifying areas of heat loss and air leaks, allowing us to pinpoint where energy efficiency improvements are needed.
- U-value Calculations: Measuring the thermal resistance of your current windows to determine how much heat is lost through them. This helps us recommend the most suitable energy-efficient window solutions.
- Shading and Orientation Assessment: Analysing your property’s window placement and how it interacts with the sun to recommend the best glazing options for maximum efficiency.


Window Design and Custom Manufacturing
We offer customized window installation solutions that cater to your home’s aesthetic and functional needs. Our designs focus on balancing energy efficiency with style. We provide a wide range of window options, including:
Double Glazing Installation: Consisting of two panes of glass separated by a spacer bar, double-glazed windows trap air, improving thermal insulation. U-values as low as 1.2 W/m²K can be achieved, which significantly reduces heat loss.
Triple Glazing Installation: Ideal for properties in colder regions or those requiring superior insulation, triple glazing uses three panes of glass with insulating gas between them. With U-values as low as 0.8 W/m²K, these windows provide exceptional insulation.
Low-E Glass Installation: Our Low-E Glass Installation service applies low-emissivity coatings to reduce heat transfer, keeping homes warmer in the winter and cooler in the summer by reflecting heat into the room.
Acoustic Glass Installation: For urban properties, we offer soundproofing solutions that reduce external noise levels by up to 70%.
Professional Window Fitting and Installation Services
Our certified installers ensure that every window is installed to the highest standards, taking care to maintain the structural integrity of your home while maximising energy efficiency. Our installation process includes:
- Accurate Measuring and Fitting: We take precise measurements to ensure a perfect fit. A poor fit can result in gaps that allow drafts to enter.
- High-Quality Seals and Insulation: We use high-performance seals around the window frames to prevent air leaks and minimise thermal bridging. This ensures that your new windows perform efficiently and last longer.
- Post-Installation Checks: Once installation is complete, we carry out a series of checks to ensure that the windows are airtight and performing as expected. We conduct thermal imaging tests and use a blower door to measure air leaks.


Secondary Glazing for Listed and Period Properties
For homeowners with listed or period properties, we provide secondary glazing options that improve energy efficiency without altering the exterior look. Our secondary glazing solutions include:
- Slim Profile Frames: These frames are specifically designed for listed buildings, allowing for easy installation without affecting the property’s appearance.
- Thermal Insulation: Secondary glazing provides an extra layer of insulation, reducing heat loss by up to 60%. This is particularly beneficial for homes with single glazing or older windows.
- Noise Reduction: Secondary glazing can reduce external noise by up to 70%, making it a perfect solution for properties located in busy urban areas or near transport routes.
We ensure that all secondary glazing installations comply with UK conservation regulations and provide documentation as required.
Maintenance and Performance Monitoring
To ensure that your windows continue to perform optimally, we offer a full range of maintenance services, including:
- Annual Checks: We offer annual maintenance services that include resealing, cleaning, and checking for any signs of wear or damage.
- Performance Monitoring: We can monitor the thermal performance of your windows over time, ensuring they maintain their energy efficiency levels.
- Window Repairs: If there are any issues with the seals, frames, or glazing, our team provides quick, effective repairs to restore performance.
By maintaining your energy-efficient windows, you can extend their lifespan and continue to enjoy lower energy bills for years to come.


Energy-Efficient Glazing for Commercial Properties
We also offer energy-efficient window solutions for commercial buildings, including offices, retail stores, and industrial facilities. Our services for commercial properties include:
- Large-Scale Installation: We provide the installation of energy-efficient windows for large buildings, including curtain wall systems and modular window systems.
- Glazing for Different Climate Zones: We offer glazing solutions suited to both colder and warmer climates to ensure energy savings year-round.
- Customized Solutions: For commercial properties, we offer customized energy-efficient window solutions based on your building’s specific needs, including enhanced safety features and solar control glazing.
