Follow this step-by-step guide as well as our tips and tricks to install a wood window successfully.
Installing a window is not hard, all you have to do is make sure you understand the kind of window you are working with. These directions are for windows without nailing flange. Most unflanged windows are constructed from wood and a majority of them have brick holding.
Step 1 – storage, delivery, and handling when on site
Parts need to be delivered to the site very close to the time of installation. Make sure you check the items to make sure they match the order you purchased. If the delivery is correct and if there’s no evidence of damage to the units or the wrapping. Be careful not to harm the product during the unloading procedure.
Pick up the door sets and windows by the outer frame and not through the ironmongery, glazing bars, or opening sashes. While carrying them make sure they are vertical to prevent them from distorting or twisting the external frame.
This will also protect the connecting joints from being damaged. Make sure you don’t drag them. And don’t use storage containers that are metal because too much heat can harm the merchandise.
If containers are utilized, make sure air can circulate liberally to all products on the pallet and avoid storing the units in direct sunlight. Instead store them in a fullwidth, shaded area off the ground.
Make sure the united stored outside are protected from external elements using a waterproof cover. For example, the cover can be heat-resistant tarpaulin. Allow the air to circulate between each unit. Products must not be stored in a humid building or damp room. If droplets of water land on the window or door horizontally it can cause the wood to swell and render the warranty invalid.
Step 2 – glazing
All products that are finished in the factory, undergo quality inspection before glazing, and again before they leave the factory. It’s up to the installer to make sure that they are protected from site activity that may mark the glass.
Make sure you don’t use abrasive pads or sharp instruments to remove marks. Revising the building regulations in the guiding documentation will empower you to perform a successful wood window installation.
Step 3 – preparation and planning
Installers need to make sure they have understood and received all the survey details and needed drawings. They also need to ensure they carry enough sealants, fixings, and trims/architraves for their installation job.
In addition, sufficient protective coverings need to be available for the immediate vicinity and all walkways near the area. Check your personal protective equipment and check to see that all the tools you have are adequate. If the installation process needs portable access equipment for working higher ground, protect the general public and customer by taking safety measures.
Step 4 – remove current windows
The first thing you need to do in this step is to measure the current structural opening and the new doorset or window to ensure they fit. If you are worried about any inconsistencies, resolve the matter before you remove the existing window.
Avoid making unneeded damage to the structural opening and to the finishes that surround it. This will save you a lot of time. If during the removal process you become exposed to any dangerous materials stop the installation work immediately and seek advice from the window manufacturer.
Windows and doors that have been removed are a hazard. Once you take them out, move them to a place of safety until you can deal with them properly. Most of the materials can be recycled. Just make sure all safety protocols are observed, for instance, if you are working in heights make sure that appropriate protection is worn for example, wear, hard hats, wrist protection, gloves, and goggles.
Step 5 – forming openings
Wooden windows can be fitted during the construction phase or at a later stage into pre-formed openings. Make sure that you don’t place them too tightly because this can lead to the frame being distorted. Clearances on the side must not exceed 10mm on every side. If you are not building them in, the opening is formable by using propriety templates or site-constructed templates.
Step 6 – fittings
Place DPCs as the construction is underway. You can do this by fixing the DPC to the frame before building it in or through fitting the DPC into the structure in the process of making the pre-formed openings.
In the latter instance, it’s convenient to utilize a DPC that is wider than needed. Make sure you don’t form a cold bridge because that could cause condensation.
Step 7 – support
To ensure you offer continuous support , at the cill level use a mortar bed when building. To stop the mortar from becoming too thin under the heaviness of the window; supporting the window temporarily while the mortar bed starts to set may be necessary.
If that doesn’t work, support the windows on packings that are durable at a maximum of 150mm from each jamb and under mullions. That way the window should be fitted plumb and level.
Step 8 – fixing
Side fixings should often be between 150mm and 250mm from the top of the frame to the bottom. It shouldn’t be more than 600mm between centers. If the window happens to be more than 1800mm wide or developed from two or more parts, provide fixings at both the cill and head.
Special requirements may be needed when adjusting windows into openings that are preformed. Unless you use fixings that are internally fitted. You’ll need to fix them through the frame, so rather go for unobtrusive locations.
Step 9 – sealing
The space between the doorset or window and the aperture must be sealed to resist water and stop the leakage of air, while also allowing any kind of movement that may happen between the aperture and the frame.
Replacement door sets and windows need to be sealed externally only. But in new build sealings, this needs to be done on both the inside and the outside. The right sealant, chosen to suit the frame and construction materials involved, will help to keep its adhesion and flexibility throughout its lifespan in service.
Step 10 – decoration
As much as possible, doors and windows must be factory finished. If you want to do additional finishings you should do this when the weather is dry. You will need to use good quality material for the exterior according to the manufacturer’s instructions to do a good-looking and sustainable job.
