Premium Sealed Glass Units Supplied & Installed
At RUK Windows & Doors, we specialise in the supply and installation of high-quality sealed glazing units — including double glazing, triple glazing, and a full range of specialist glass options. Whether you’re replacing fogged-up panes or upgrading to more energy-efficient units, our Leicester-based team is trusted across the Midlands and surrounding areas for delivering professional results with a friendly, no-pressure approach.
What Is a Sealed Glazing Unit?
A sealed glazing unit (SGU) — also known as an insulating glass unit (IGU) — is the glass component of your window or door. It typically consists of two or three panes of glass, separated by spacer bars and sealed together to form an air or gas-filled cavity.
These units provide insulation, reduce noise, and help prevent condensation. We offer SGUs for:
- Existing window and door frames
- New-builds, extensions, and refurbishments
- Residential and light commercial properties
If your glass is misted, cracked, or outdated, we can replace just the glazing, without touching the surrounding frame — saving you time, money, and disruption.
Double & Triple Glazing Options
Double Glazing
Our double glazing units are made up of two panes of glass with a sealed spacer in between, filled with either air or argon gas. This creates a thermal barrier that:
- Keeps warmth in
- Keeps cold out
- Helps reduce heating bills
- Minimises outdoor noise
It’s the most popular choice for UK homes and ideal for most situations.
Triple Glazing
Triple glazing features three panes of glass and two insulating cavities for superior thermal efficiency and acoustic performance. It’s perfect for:
- Energy-efficient new builds
- Homes near busy roads
- Those looking for long-term savings
Specialist Glass Types
We offer a wide selection of high-performance glass types, tailored to your needs:
Low-E Glass
Coated to reflect heat back into your home while allowing sunlight to pass through. It’s energy-efficient, eco-friendly, and ideal for keeping your space warmer for longer.
Self-Cleaning Glass
Coated with a clever layer that breaks down dirt and washes it away naturally with rainwater — great for skylights, conservatories, or hard-to-reach places.
Toughened (Safety) Glass
Up to five times stronger than standard glass and designed to shatter into safe, blunt fragments — essential for doors, low-level glazing, and bathrooms.
Laminated Glass
Two layers of glass bonded by a tough plastic interlayer. It remains intact even if broken, offering better security and noise reduction.
Obscure / Frosted Glass
Provides privacy without blocking natural light. Perfect for bathrooms, entranceways, and side panels.
Acoustic Glass
Specifically engineered to reduce outside noise. Ideal for homes near airports, train lines, or main roads.
Decorative & Patterned Glass
Choose from a variety of designs to complement traditional or modern homes — ideal for side panels, front entrances, or bespoke features.
Replacement Glazing Services
You don’t always need to replace the entire window or door. In many cases, the frame is still perfectly fine — it’s the glass that’s failed. We provide fast, affordable sealed unit replacement for:
- Misted or fogged-up glazing
- Cracked or smashed panes
- Failed or leaking units
- Single glazing upgrades
- Energy-efficiency upgrades (double or triple)
Let our team assess the condition of your existing glazing and advise on the best solution.
