Homeshield Scotland - Double Glazing FAQs

Here are some of our frequently asked questions by our customers.

Double glazing is a type of window setup that allows for two panes of glass within a single frame, separated by a gap filled with a gas that has high insulation ability. This slows the movement of heat from inside the house to the outside, as well as noise coming in from the outside, allowing you to live in peace.

Double glazing can be installed within a range of different types of windows and doors, including French doors, patio doors, upvc doors, and also specialist windows etc.

Choosing to replace your single-glazed or old double-glazed units saves you money from day one. In fact, choosing Homeshield double-glazing could reduce your heating costs by up to 20% – saving a significant amount of money each year

High-Quality Energy Efficient Materials

Up to 80% of a double-glazing unit’s energy loss occurs at the glass edge, however, our windows come fitted with a warm edge spacer with advanced composite construction. This makes windows in Glasgow shine due to the cold weather that is notorious in central Scotland.

Lower heat loss at window edges makes our glass 3-4°C warmer, cutting condensation by up to 80%. In addition, due to the use of high-performance gaskets, our double glazing reduces noise pollution too.

Robust and Resistant

Our windows feature innovative Q-Lon weather seals. Offering high-quality windows with exceptional performance over a wide temperature range, the unique construction actively absorbs noise pollution, increasing acoustic insulation. Immune to rot, mould, mildew, UV, and ozone, CFC-free Q-Lon weather seals will last the lifetime of a window.

Yes, it’s entirely possible to have replacement windows and doors supplied with double glazing. There are some factors to look out for, such as the material of the frames and sometimes even building regulations, but installing double glazing is one of our most popular services due to the impressive benefits that double glazing offers. Triple glazing windows are also an option for households whose own personal requirements mean that may need a greater level of thermal efficiency and noise reduction provided by triple glazing.
This is a common misunderstanding of terms, as it’s entirely possible to have double and triple-glazing UPVC windows, as UPVC simply refers to the materials used in the frame of the window. UPVC windows are a popular choice due to their energy efficiency, durability and low maintenance. UPVC windows in Glasgow are a worthwhile investment due to their energy efficiency abilities – a key factor in the cold conditions of central Scotland – as well as their high levels of durability and low maintenance.

Both styles of windows in Glasgow will serve the same vital purpose – reducing both heat loss and noise pollution. However, they differ in style and installation method.

Double Glazing has a pocket of insulated air in the middle of the two panes of glass and are installed as a complete unit. Secondary glazing, however, is installed by adding the second pane of glass, or alternatively a plastic panel, to a single-glazed window on the interior side. This panel creates a gap filled with air between the original pane and the new one.

Of the two formats of glazing, it’s widely accepted by double glazing companies in Glasgow and beyond that double glazing is more effective than secondary glazing. The reason for this is that the insulating gas is more than just air, it’s often argon or krypton, which is far more effective and protects against energy loss. On top of that, it comes together as a professionally constructed unit, meaning it is ensured to have a tight seal made up to industry standards.

That being said, secondary glazing does have an advantage in that it’s less intrusive, meaning that it’s far more likely to be accepted in listed buildings, or other areas that have similar protections.

We offer a range of of options for double glazing in Glasgow, and some of the most popular include:

Sash Windows
Our vertical sliding sash windows combine the elegance of a traditional sash window with the benefits of modern materials. Manufactured from uPVC they are strong and will not rot, warp or require repainting; ensuring your new windows retain their colour and shape throughout the years.

Tilt & Turn Windows
The Tilt and Turn window allows you to enjoy the key benefits of a truly versatile product, offering both aesthetic and practical options. Tilt and turn windows are available in a number of style options, allowing larger opening areas to be achieved for fire-safe escape openings.

Casement Windows
Our range of double-glazing casement windows is our most popular design, offering security, and energy efficiency. All of our windows are available in a multitude of stylish designs and finishes to enhance the look of your home. Whatever style you go for, you’ll find your new windows aren’t just pleasing to the eye, they’re practical too.

As strange as it may sound, the answer is yes. Double glazing is not built specifically for this purpose, of course, but due to its high degree of control over what manages to travel in through your windows, outside pollutants and other such triggers can be prevented from entering your home.

On top of this, the temperature control alongside the anti-condensation measures means that the moisture that would otherwise enter your home. Having a dry home means fighting against mildew, mould, and other bacteria that grow in the moist that have foul effects on the lungs.
