Advanced Double Glazing Solutions: Enhancing Security, Comfort, and Style

Window & Door Glass Options

In recent years, advancements in glass technology have significantly improved the quality and energy performance of Double-Glazed Windows. The introduction of gases like Argon, Krypton, and Xenon into these units has enhanced U-values, complementing the new Energy-Rated Windows and Doors. As a result, homeowners now enjoy better security, soundproofing, and privacy. Whether your goal is to enhance security, reduce noise, or create a more private space, our Double-Glazing Solutions cater to a wide range of needs.

Security Secure by Design Glass

Enhance the security of your ground-floor windows and doors with upgrades to Secure by Design (SBD) standards. We offer external glass units with laminated glass on the outside and Energy-Efficient glass on the inside. Additionally, Argon gas fills the space between the panes to improve U-values. Clips fitted into the frame prevent the glass unit from being removed during a security breach.

Soundproof Glass

For soundproofing, our Pilkington Optiphon™ glass is an excellent choice. Designed to reduce noise from roads, railways, and air traffic, this laminated glass includes a special Polyvinyl Butyral (PVB) interlayer. We recommend using 6.8mm laminated glass, which consists of two layers of 3mm glass with a 0.8mm PVB layer. This setup effectively reduces noise without compromising light transmittance or impact performance.

Thermal Efficiency and Noise Reduction

Our windows are designed to keep your home warm, safe, and quiet. Paired with ISO-BLOCO HYBRATEC Energy-Efficient Insulation Tape, which is 100% waterproof and offers improved U-values, our windows can significantly enhance thermal efficiency. Moreover, they reduce noise by up to 63dB of sound transfer and enhance window insulation.

Pilkington Textured Range

Our Pilkington Obscure Glass offers 21 unique textured designs, from traditional patterns like Arctic and Stippolyte to contemporary options like Tribal and Cassini. Available in toughened or laminated versions, these designs balance light filtration and privacy, with obscuration levels ranging from 1 to 5.

Pilkington Oriel Range

The Oriel Collection features etched glass designs that provide excellent light transmission while offering varying degrees of privacy. These modern designs have a smooth, matte finish, making them both attractive and functional.

Stained Glass Overlay (SGO)

SGO Fanlight

Our Stained Glass Overlay (SGO) replicates traditional lead designs using self-adhesive lead in various widths and finishes. We offer custom designs and colours, which are sealed inside the double-glazed unit for a lasting, authentic look.

Bevel Designs

Modern techniques have improved the manufacturing of bevels, making them more energy-efficient and environmentally friendly. Available in colours like bronze, blue, and green, bevels can be combined with coloured film overlay and lead tape for various design options.

Standard Window and Door Units

Our standard units come with 4mm glass, either annealed or toughened, depending on the location. We use energy-efficient Low-E glass, like Pilkington K Glass™ or Pilkington Optitherm™, to prevent heat loss. These units improve thermal insulation by over 50% and feature a 28mm double-glazed setup with a warm-edge spacer bar to enhance thermal efficiency.

Warm-Edge Spacer Bar

Warm-edge spacer bars significantly reduce heat loss at the window’s edge. They come in three colours and various sizes to accommodate different glass thicknesses, providing both environmental and cost benefits.

Double-Seal

Our Thermobar tube, with a specially designed non-metallic tape, creates a moisture- and gas-resistant barrier. This design ensures lower psi values in uPVC window frames, contributing to overall energy efficiency.

Toughened Glass Units

All glass below 800mm from the internal floor must be laminated or toughened for safety. Our 6mm toughened glass option offers enhanced security, thermal insulation, and sound reduction.

Equal Sight Lines

Casements with equal site lines.

Equal sightlines or dummy vents replicate the aesthetic of traditional wood windows with false vents. These elements blend functionality with style, ensuring a consistent and secure appearance.

Leaded Designs

We can replicate various lead designs, including square, rectangular, diamond, and Queen Anne styles. Provide a picture of your desired design, and we will work to recreate it.

Roy and his team fitted new windows and French doors in our house earlier this year (we wanted to live with them for a while before reviewing!). We are really pleased with the quality of the windows and the service from Roy. He's a real gent to deal with and is punctual and professional. His quote wasn't actually the lowest but he was the only one to supply full details of materials, give fire safety and security advice, send a detailed quote etc. Thank you Roy

I got quotes from a few companies however Peter was the only one who followed up to my questions on email so I decided to go with Southeast Windows. I am super glad I did, as Peter was professional and I am really happy with the work done in installing a new PVC backdoor and replacing glass in several windows. Peter was knowledgable, friendly and didn't take advantage of my lack of knowledge of window and door installation like some other builders have, being a first time home owner.I wouldn't hesitate to recommend Peter and Southeast Windows, I will for sure be using them again if I need. Thank you Peter!
