Windows, being a very crucial feature in every home, are one of the things you simply can’t afford to ignore in your home. Having a good understanding and solid knowledge of your windows’ components like the window sash will help you stay up to date with them and able to identify any minor mishaps early on before it leads to a much bigger problem. So what exactly is a window sash?
Well without much fuss, a window sash is simply that part of your windows that’s able to open and close. And there could as well be more than one window sash that’s operable depending on your window’s type. Window sash usually possess a very basic design as well as structure. What’s more? This section of a window happens to be a frame that’s designed in such a way to make for easy placement inside the whole window casement. You’ll discover inside the sash frame, the window glass alongside any framework possessed by your window which includes grids.
Usually, the sash is fitted into the frame of the window on a runners’ set in such a way that allows for both upward and downward movements. And finally, the window sash’s frame typically comes with a locking system which provided for extra safety and security.
The window sash is a vital feature that can determine the durability and overall performance of the windows. In the event whereby your window sash is malfunctioning, it can result to numerous problems which includes both drafts as well as leaks. As a result, it’s very important to keep your window sashes in a great working condition as failure to do so will make opening and closing your windows a really difficult task.
All new windows come with an energy efficiency rating from A to G. A is best, while G is the lowest rating. Anything above C is considered good, but these days most companies will be able to supply you with A-rated windows to maximise your energy efficiency.
Double glazing frames don’t just have to come in uPVC and are available in other materials including aluminium and wood too. Wooden or timber windows are more suited to properties with a traditional look and are often the frame of choice for listed buildings and homes in conservation areas. When properly maintained wooden windows can last well for years but can be up to three times more expensive than uPVC.Aluminium is the strongest and most durable option. As a metal it is highly resistant to the UK’s changing weather conditions and won’t rust, warp, crack or peel. Aluminium offers a modern appeal and is available in a range of colours.
Unfortunately, you can’t fix the glass on one side of a double glazed window. That’s because they’re sealed units – once one pane of glass is broken, that will break the seal and its thermal insulation properties will be lost.
The good news is that if your window frame is still looking great, there’s no need to replace that. You can simply replace the glass in the window, which will cost much less. You can look to spend around £250 on a sealed unit, whereas a whole replacement single window may cost up to £600.
When an installer comes to replace the glass in your double glazed window, they will survey the inside and outside of your home around the window, then move any furniture by the window so they’ve got access. They should then pop a dust sheet down to stop any debris from getting on your floor.
Then, the installer will carefully remove the beads from the frame. They will then lift the glass out of the frame and put it somewhere safe before cleaning out all of the dust and any debris that has found its way into the frame. Using spacers at the bottom of the frame, the installer will make sure that the sealed unit is square in the frame to get a good fit. Once they’re happy, they will replace the beading and make sure it looks perfect before cleaning up their tools.
You could have a go at replacing the glass on a double glazed window yourself, but it’s not recommended. Leave it to the professionals who will know exactly what to do and will be able to do it quickly and safely.
Most installers will not need you to be at home while they are fitting your windows. It is a good idea to be present though, just in case they have any questions for you and perhaps for your own peace of mind. If you cannot be there, you will need to arrange access to the property and/or agree securing the property at the end of the day.
You can only repair blown double glazed windows in the sense that you can replace the sealed unit (the glass part of the window) instead of having to replace the entire window.
When a double glazed window is blown, it means that the seal around the window has failed and is now letting air in and out. Often the first sign that the sealed unit has blown is condensation on the inside of the window, which is annoying since there’s no way to get rid of it! When your sealed unit has blown, you’ll be losing heat out of the window, meaning you could be spending more on your energy bills.
As a temporary fix, you could see if you can buy a misting repair kit online, but the condensation will eventually occur again as the air gets in. The best thing to do is ask a window installer or glazier to replace the sealed unit for you.
It's simple to replace the glass in a window – the specialist will remove the beading around the window, remove the blown glass from your window frame and set it to one side. They will then clean up around the frame before adding spacers in, then fitting the new sealed unit into the frame. They’ll make sure it’s a snug fit before replacing the beading back around the window to secure it.
There's no reason to put off repairing a blown double glazed window since the cost is generally much less than replacing the entire thing. A sealed unit with installation costs an average of £100, whereas a completely new window will cost around £400. You’ll soon notice that it’s less draughty and will be able see out of your window once you’ve had the blown glass replaced.
No matter how big or small a building is, it can only be as good as it’s foundation - and that’s a fact! It all starts from the footing and when it isn’t deep enough, unlike badly installed gutters or gapped hardwood flooring, can make the whole building collapse to the ground. Just like any code recommendations, the depth of the footings of your porch is a parameter that must be complied with and adjusted to suit your local code requirements.
As a rule of thumb, you should always dig below the frost line when excavating your footings. At this depth level, the moisture present in the soil will be frozen. Ultimately, this will help the ground to act as a barrier to insulate the soil below the footing from freezing during the cold months. As a result, in regions where the weather is almost always very cold the depth of your footings is expected to be at least 48 inches. But in areas featuring a warm climate, you may be allowed to install your footings on grade.
In addition, it’s compulsory that your footings must be installed at a minimum depth of 12 inches below unsettled soil. However, if you’re constructing the structure into a steep hill’s side or by the side of a retaining wall, it’s required that you maintain the least distance to grade both vertically and laterally. In the event whereby you need to achieve a good lateral barrier, you’ll need to have your foundation dug a lot deeper compared to if it’s on a flat surface. For a more accurate and updated information, you can consult your local building inspection department to get familiar with the requirements in your area.
