What does the Job Entail?

Bi-fold, sliding and French doors are great for offering a beautiful view of your garden, making them a very popular choice for home improvement endeavours in Britain. Bi-folding doors are considered the most preferred since they can be used to replace entire walls to offer some impressive views towards the back part of the property. While sliding doors offer the same sight when they’re closed, bi-folds offer the best possible views when they’re left open, especially when the weather is good. It is a fact, however, that in terms of costs, bi-folds are considered as the priciest. Also, they may not be suitable for certain types of properties. They can be quite tricky to install as well. 

The structure you plan on attaching the top track to must be sturdy enough to support the added weight. The sill will also need to be prepared for the assembly of the door frame that will have to be installed into the opening. Once it is level, one must ensure that it is tight and nice by using packing. Holes will then be drilled along the sides of the door frame for the bolts. The head and sill will be fixed next whilst ensuring that the sill is properly level and that the door jambs are accurately vertical. After making sure that all the door fixings are put in place, the hinges can be attached, based on the manufacturer’s instruction. Don’t forget to fit in the multipoint locks before hanging your door for security purposes. After the locks and hinges are installed, the pivot hinges on the bottom and the top will need to be adjusted so the doors are indeed vertical once they are fitted. 

Bi-folding doors are ideal for merging your indoor and outdoor space— but this only works if you have a beautiful garden to showcase in the first place. You’ll want to have a hard landscaping right out of the doors too, so you won’t have to worry about stepping on mud whenever you use these doors to get to your garden. If you have set your sights on two-fold doors, make sure that your garden is up to par. Adding a patio is not a bad idea. Upgrading your garden may also be something you’d want to consider, especially if your budget will allow it. 

Do I Need Planning Permission?

The addition of doors to your home may be considered a permitted development. In most cases, planning permission is no longer necessary. However, there were unusual cases where permission might be required, when in doubt, you can always refer to your local council for proper clarifications. You’ll also need to check if the opening lintels are suitable for the installation. In the event that the aperture isn’t the appropriate height or width, you may need to employ the services of a structural engineer to get the issue patched. 

Will Bi-folds Improve My Property’s Value?

Most home improvements are going to have a positive effect on your property value. According to experts, the addition of bi-folding doors to your home, especially high-end ones, can add up to 5% to your property’s resale value. Two-fold doors tend to offer more where increased resale value goes compared to patio or French doors because it can span an opening of a good several metres for the property, leading to a rather more sensational and impressive effect.

Aluminium vs Wood vs uPVC

Aside from size, you’ll also need to consider the material of the dual-fold doors you plan on installing as it can have an effect on its longevity, aesthetics and performance. These doors could be made up of aluminium, wood or uPVC. If you’re looking for a traditional and distinctive look, you go for wood. However, they do have a downside of warping over the years so maintenance is something you need to invest on. 

Aluminium would be considered as the most popular. Stronger than those made of uPVC or wood, they will allow for frames that are thinner as well as more glazing, resulting in more light. They are also more resistant to warping and they do not need any maintenance at all. 

Doors made from uPVC are considered weaker compared to hardwood or aluminium. They will need ticker frames but they’re ideal for those that want to minimise the costs. Whilst they appear to be the better value option especially at first glance, they may prove costlier in the long run as they may not last you as long as timber or aluminium. They aren’t that popular an option too so where property value is concerned, they may not offer that much. 

If you’re looking for the most heat-efficient option, timber is the right choice for you. Aluminium may not be the most energy-efficient material of the bunch. However, non-conductive materials are often used in quality dual-fold doors made from aluminium to serve as thermal break.
