Glass Options for Your Sapphire Windows & Doors

The glass you choose for your windows and doors can make a bigger difference than you might think.

Whether you’re looking to reduce outside noise, improve energy efficiency, increase privacy, control the heat from the sun or bring more natural light into your home, there are glazing options available to suit your needs.

At Sapphire Windows & Doors, we offer a range of specialist glass options for our replacement windows, doors and rooflight solutions. We can help you understand the differences between each option, so you can choose glazing that works for your home, your lifestyle and your budget

Acoustic Glass – For a Quieter, More Comfortable Home

Fed up with traffic noise, aircraft or other outside sounds making their way into your home?

Acoustic glass can help create a quieter and more comfortable living space.

Acoustic laminated glass uses a specialist acoustic PVB interlayer that helps absorb and disrupt sound waves as they pass through the glazing. This can provide greater noise reduction than standard laminated glass of the same thickness.

It’s a particularly useful option for homes close to busy roads, airports, schools, pubs, commercial areas and industrial sites.

As well as helping reduce unwanted noise, acoustic laminated glass retains the familiar benefits of laminated glazing, including enhanced safety, security and UV protection, while still allowing plenty of natural daylight into your home.

How does acoustic glass reduce outside noise?

Acoustic glass uses a specialist acoustic PVB interlayer that helps absorb and reflect sound waves. This disrupts sound frequencies and reduces the amount of unwanted noise entering your home.

What types of noise can acoustic glass help with?

Acoustic glass can be particularly useful for reducing environmental noise from road traffic, aircraft, school playgrounds, bars, industrial areas and other busy surroundings.

Will acoustic glass make my home darker?

No. Acoustic laminated glass can provide high levels of natural light while offering improved acoustic performance alongside safety, security and UV protection.

Double Glazing

For the last 30 years, Sapphire Windows have been installing high-quality double glazing in homes throughout Wales.

By incorporating the best performing double glazing into our windows, we ensure that we supply the very best in terms of energy efficiency and thermal performance, exceeding the minimum standards imposed. By doing so will help keep your home well insulated and your energy bills kept low.

Our double glazed windows are A-rated as standard. The building regulations state that replacement glazing must have a minimum window energy rating of band C

Triple Glazing

The extra glass panel reflects more heat into your home, making it warmer and helping to cut your heating bills even further. Triple Glazing is an excellent choice for cutting out external noise, too, ensuring you feel a big difference in any room. Our triple glazing features two panes of low-emissivity (Low E) Glass and one pane of Low-Iron glass. Low E is an invisible coating that allows heat past the window from the outside and reflects into the home from the inside. This saves a great deal of energy and money off your heating bills. Our triple glazed sealed units are filled with two chambers of argon gas. Argon gas is heavier than air and acts as an insulator, this helps block out noise as well as cold air. The panes of glass are separated by warm edge technology spacer bars. These act as yet another barrier to heat loss

Leaded & Georgian Bar Glass Designs

There are a wide range of glass effects from which you can choose to closely match the pattern you prefer.

All our glass options are available toughened or laminated for your security and safety.

Leaded Glass Designs can be seen in both modern and traditional properties alike. Leaded designs really can add elegance and grandeur to uPVC windows.

The most popular lead designs are the classic diamond lead or traditional square lead as shown below. However, we can create bespoke leaded designs to suit your style.

Diamond Leaded

Square Leaded

Georgian Bars are available as external Georgian bars, which sit on the face of the glazing. Or as internal Georgian bars, which sit in between both panes of the sealed unit. Internal Georgian bars are a more cost-effective option and low maintenance option.

The design of the Georgian bars can be tailored to your window design; each pane can be split in to as many sections as you choose. The panes on the example below have been split into eight.
