Velux Glass Replacement

See through your Velux window, without the cost of replacing the frame.


Whether you have misted or condensation between the glass, cracked or broken units, or an annoying leaky Velux window, Double Glazing Repairs can help revive your old Velux window back to life.

(Leaks through your plasterwork require a roofing specialist.)

All glazing is sealed with butyl sealants, just like when they left the factory. We do not use double-sided foam tape or silicone sealants when bonding replacement glass into your window.

What is Toughened Safety Glass?

Toughened safety glass, also known as tempered glass, is a type of safety glass that is commonly used in double glazing for its enhanced strength and safety features. Here are some key points about it:

Strength: Toughened glass is significantly stronger than regular glass. It undergoes a special heat treatment process that increases its strength and makes it more resistant to impact.

Safety: When broken, toughened glass shatters into small, blunt pieces rather than sharp shards. This reduces the risk of injury, making it a safer option for areas where glass breakage could pose a hazard.

Applications: It is often used in places where safety is a priority, such as in doors, windows, shower enclosures, and other areas prone to impact.

Thermal Performance: In addition to its safety benefits, toughened glass can also provide better thermal insulation when used in double glazing, helping to improve energy efficiency.

Overall, toughened safety glass is a reliable choice for enhancing both the safety and performance of double-glazed windows.

What is Argon Gas?

Argon gas is commonly used in double glazing to improve the thermal insulation of windows. Here are some key points about its use:

Thermal Barrier: Argon gas is denser than air, which means it has lower thermal conductivity. When sealed between the panes of double glazing, it acts as an effective thermal barrier, reducing heat transfer between the inside and outside of a building.

Energy Efficiency: By minimizing heat loss in the winter and heat gain in the summer, argon-filled double glazing helps improve the overall energy efficiency of a home, potentially lowering heating and cooling costs.

Non-Toxic and Safe: Argon is a non-toxic, colorless, and odorless gas, making it safe for use in residential and commercial buildings.

Noise Reduction: In addition to thermal benefits, argon gas can also help reduce noise transmission through windows, contributing to a quieter indoor environment.

Overall, argon gas enhances the performance of double-glazed windows, making them more effective at insulating and providing a comfortable living space.

What is Warm Edge Space Bar?

A warm edge spacer bar is a component used in double glazing to improve the thermal efficiency of windows. Here are some key points about it:

Material: Unlike traditional spacer bars made from aluminum, warm edge spacer bars are typically made from plastic composite materials. This helps to reduce heat transfer at the edges of the window.

Thermal Performance: They act as a thermal break, minimizing heat loss and reducing the risk of condensation around the edges of the window.

Energy Efficiency: By improving the insulation of the window, warm edge spacer bars contribute to lower U-values, which measure the rate of heat transfer. This makes windows more energy-efficient.

Comfort: They help maintain a more consistent indoor temperature, enhancing overall comfort in the home.

Overall, warm edge spacer bars are a small but significant upgrade that can make a big difference in the energy efficiency and comfort of your home.

What is Low-E?

Low-E (low emissivity) glass is a type of energy-efficient glass used in double glazing to improve thermal performance. Here are some key points about Low-E glass:

Coating: Low-E glass has a microscopically thin, transparent coating of metal or metallic oxide. This coating is applied to one of the internal surfaces of the double-glazed unit.

Heat Reflection: The coating reflects infrared (IR) heat back into the room, reducing heat loss in the winter. It also helps to keep the heat out during the summer, maintaining a more consistent indoor temperature.

Energy Efficiency: By reducing the amount of heat that escapes through the windows, Low-E glass helps to lower energy bills and improve the overall energy efficiency of a home.

Light Transmission: Despite its reflective properties, Low-E glass allows natural light to pass through, ensuring that rooms remain bright and well-lit.

Overall, Low-E glass is an effective way to enhance the insulation properties of double-glazed windows, contributing to a more energy-efficient and comfortable living environment

What is Energy Saving Glass?

Energy-saving glass in double glazing is designed to improve the thermal efficiency of windows, helping to reduce energy consumption and lower heating and cooling costs. Here are some key points about energy-saving glass:

Low-E Coating: Energy-saving glass often features a low-emissivity (Low-E) coating. This microscopically thin, transparent coating reflects heat back into the room during winter and keeps heat out during summer, enhancing thermal insulation.

Gas Fill: The space between the panes of double glazing can be filled with inert gases like argon or krypton, which have lower thermal conductivity than air. This further reduces heat transfer.

Improved U-Values: Energy-saving glass helps achieve lower U-values, which measure the rate of heat transfer. Lower U-values indicate better insulation and energy efficiency.

Comfort and Cost Savings: By reducing heat loss and gain, energy-saving glass helps maintain a more consistent indoor temperature, leading to increased comfort and potential savings on energy bills.

Overall, energy-saving glass is an effective way to enhance the performance of double-glazed windows, contributing to a more energy-efficient and comfortable living environment.

Why did my glass mist up?

Double glazing units can fail for several reasons, often leading to issues like condensation between the panes, drafts, or reduced insulation. Here are some common causes:

Seal Failure: The most frequent cause is the failure of the seal between the two panes of glass. This can allow moisture to enter, leading to condensation and misting.

Poor Installation: If the double glazing is not installed correctly, it can lead to early failure. Faulty installation can cause the seals to break or not form properly.

Wear and Tear: Over time, the materials used in double glazing can degrade. This natural wear and tear can cause the seals to fail and the unit to lose its effectiveness.

Thermal Stress: Significant temperature changes can cause the glass to expand and contract, putting stress on the seals and potentially causing them to fail.

Material Degradation: The materials used in the construction of double glazing units, such as the spacers and seals, can degrade over time due to exposure to the elements.

Regular maintenance and proper installation by qualified professionals can help extend the life of double glazing units and prevent these common issues.
