DDG Windows Double Glazing

Secondary glazing offers multiple key features that enhance window performance, including significant sound insulation, improved energy efficiency, and condensation reduction. By creating an extra insulating layer, secondary glazing helps retain heat, lowering heating bills and making it a cost-effective solution for increasing comfort in older buildings. Customisable options for thickness and ventilation further make secondary glazing adaptable to unique window needs, such as vertical sliding for sash windows. We provide a range of double glazed doors, from emergency Shop front repair doors to patio doors.
Britannia Windows is a well-known family business that was founded in 1982. Serving customers in Kent, Sussex, Essex, Surrey and London, the company uses a network of installers to ensure quick delivery. Britannia Windows gets mixed reviews online, but it responds directly to negative reviews and has a solid reputation overall.

Being reversible and invisible from the outside, it complies with rules for listed buildings. It’s effectively double glazing without you having to lose your original windows. The extra layer of glass in a double-glazed unit also helps to reduce noise levels from outside, making your home far more comfortable and peaceful to live in. We can tailor our glass and glazing services to all types of commercial properties, no matter their size or scale. If you want to save money on heating then you need to look at A rated windows or higher. Lower ratings than A mean that the window will let heat out of your home meaning you need to spend more keeping your home comfortable.

We provide free site visits, same-day turnarounds and full guarantees on all glazing. Just an expert team of glazing specialists dedicated to helping you get the glass you need. Switching from single glazing to double glazing can save you a significant amount on your energy bill. We can help with misty and broken glazing through to faulty window and door hinges, handles, locks and mechanisms. Replacement windows will be more airtight than your original frames, so condensation may build up in your house due to the reduced ventilation.
It's also worth looking for an installer that's part of an Alternate Dispute Resolution scheme. Being signed up to one should make things a lot easier if anything goes wrong or there is a dispute. For example, the Double Glazing & Conservatory Ombudsman (DGCOS) is well regarded in the glazing industry. It also means the work is covered by an insurance-backed guarantee if it's not compliant or the company goes bust. The decision was made based on impression formed and their responses to our questions.

The two layers of glass are tougher to break than single glazing, providing an extra layer of protection for your home. Our double glazing products are designed with security in mind, featuring robust frames and high-quality locks. According to the BFRC, double glazing windows are rated between A++, providing the highest level of energy efficiency, and E, the lowest. UK building regulations require that all new windows be at least C-rated. Most double glazing companies have developed units with different levels of energy efficiency, some as high as A++, allowing you to choose the best option for your home and your wallet.

I went for Richard, since his prices were competitive and he got my attention with his wonderful honesty. "I'm talking myself out of a sale," he said, "your windows aren't too bad..." Actually I went for it. 85% of tenants care about double glazing, my estate agent reckoned, and Richard's are the best. We pride ourselves on installing the most innovative, eco-friendly products on the market today.
Read all the testimonials and customer reviews you can find, and check out third-party websites. While every installer will have some negative reviews, the company’s response to such criticism can help you gauge its level of professionalism. Good aftercare service is more likely with companies that are willing to correct any issues. We've also heard about instances of double glazing salespeople quoting a high price to begin with, and then dropping it over the course of their sales visit to encourage you to sign on the spot.
