How to Install uPVC Windows

New to installing uPVC Windows and wondering how to do it? Don’t worry.

uPVC windows are a desirable addition to any home and offer a wealth of benefits.

However, incorrect installation can lead to myriad problems, from decreased energy efficiency, to damp and the many issues associated with that complaint.

This guide on installing uPVC Windows should help you get to grips with installing uPVC windows correctly to ensure the homeowner enjoys the maximum benefits from their investment. 

Remember: Always follow manufacturer instructions. The steps below are. a guide only.

Tools Required 

As with any task, the appropriate tools should be used to ensure a satisfactory finish. Before you start installing uPVC windows, you’ll need to make sure you have the following to hand: 

  • Chisel 
  • Stanley knife 
  • Nail bar 
  • Spirit level
  • Drill and bits
  • Screwdriver 
  • Saw 
  • Frame fixings 
  • Door and frame sealant 
  • Metric tape measure
  • Light hammer 
  • Pencil 
  • Gloves 
  • Goggles

Preparation 

Before you start, make sure you’ve fully prepared as mistakes are difficult to rectify later in the process. First, check that each window opening has a lintel above as uPVC windows are not designed to be load-bearing. You’ll also want to check that the windows that have been delivered are the ones you ordered and then clear the space around each window, removing ornaments and drapes etc. before beginning. 

Remove existing window

Cover the surrounding area with sheets before beginning. 

Using a screwdriver, remove the opening part of the window. A nail bar will be required to remove sash style windows. Then crack the glass from the frame, starting at the top left corner. Be sure to wear gloves and goggles for this to avoid injury. 

Using a Stanley knife, cut through the plaster seal around the window frame then use a crosscut saw to cut through horizontal and vertical frame members. Finally, use your nail bar to pry the frame away from the plaster line. 

Fitting the new windows 

Place the windowsill onto the brickwork. The uprights should sit flush against the plaster line of the jambs. If required, cut the sill horns to fit around the brickwork. 

Using plastic packers, level the sill with 5mm clearance from the brickwork then secure the sill to the brickwork using 8x100mm fixing bolts. These should be positioned approximately 150mm from each end and then at 600mm intervals. Check the level as you go and be sure not to overtighten the fixing bolts. 

Place a bead of silicone along the back edge of the upstand and then use superglue to secure the end caps into position. If the sill horns have been trimmed, the end caps will need trimming to match. 

Next, remove the glazing beads from the frame of the window, taking care to mark them so they can easily be replaced. 

Now move the new window into place, taking care that the base is snug against the sill upstand, ensuring a tight seal against the silicone bead, wiping away any excess silicone. 

Using your level, check the window is vertically level and then wedge into place with plastic packers, ensuring the frame isn’t bent from overpacking. 

Be sure that the window vents are open as this will allow access to the outer frame jambs, then secure the bottom of the window to the sill, using 8x40mm screws 150mm from each corner and then at approximately 600mm intervals thereafter. 

Using 8x100mm bolts, secure window jambs to the surrounding brickwork. Bolts should again be placed 150mm from each corner and then at 600mm intervals. Make sure all screw heads are standing correctly in order to avoid problems when placing the glass. 

Shut and lock sashes and then check the outer edges for squareness before moving on to inserting the glass. 

Installing the glass

Before installing the glass, insert 25x100x15 glazing brides into the recess, using a small amount of silicone to keep the packer secure for the next step. 

Place a 28x100x5 glazing bride onto the bottom glazing bridges. Then place a glass sealed unit into the aperture, ensuring it rests squarely on the glazing packers and push as far back as it will go into the rebate without using too much force. 

Using only hand pressure, place additional 2mm glass packers where required to square the pane then carefully lock and unlock the windows to ensure no binding occurs within the locking system and that there is no movement between the glass and frame. 

Clip the glazing beads back into position, starting at the top, then bottom and then sides then gently place a bead of silicone between the masonry and the window edge, wiping off any excess. 

Finally, place a thin bead of acrylic between the plasterwork and the window and allow one hour to skin over before removing any protective tape and cleaning necessary areas with warm, soapy water.

Price Vs Quality – Which to Choose When Purchasing Supplies

In these economically uncertain times, there’s a perception among home improvement companies that homeowners are being more careful with their money.

This has led to a ‘race to the bottom’, with home improvement providers competing to provide more affordable solutions for their customers.

As a homeowner, you may think that this means a more cost-effective product or service. However, with reduced costs, you often end up with reduced quality as well, which can, in the long run, end up costing you more. 

So if you’re looking at purchasing supplies like double glazing or a new conservatory, should you be looking at investing in the best available in the market? Or would you get the same benefit from a cheaper installer? 

Quality First 

According to a recent survey conducted by CERTASS, quality is the main driver behind home improvement decisions. While consumers are being more careful with their money, they are also being more considerate about where they spend their money. So rather than reducing the cost of their initial investment, homeowners are actually seeking out higher quality products and installations to ensure their investment is a safe one that will last for years and add real value to their home. 

If you’re looking at replacing your double glazing, you should definitely seek out the best provider you can afford. Do this by checking previous work they may have done, obtaining references and ensure they carry all the relevant certificates and accreditations. 

Value for Money 

That’s not to say that you should completely ignore the price of the product. Neither should home improvement companies simply charge whatever they want under the assumption that a higher investment automatically means higher quality. 

But you shouldn’t feel like you have to bankrupt yourself in order to replace windows. A reputable home improvement company, like MLI, will be able to provide you impartial advice on how to get the most out of your budget.

The key is to get the best windows you can afford. That means having an idea of budget in mind before contacting home improvement companies. Then find the ones that offer the highest standards and see what they can do for you on price, without cutting corners. 

When purchasing any home improvement, it’s important to get the right balance of quality and price.Get in touch with us today to see how we can help with your project and providing the right supplies, at the right price, at the right quality.

What’s the Difference Between a Conservatory and an Orangery?

Orangery is a term that’s been around for a few years now but it’s one that still has a bit of mystery surrounding it. And if you’ve ever been in the situation where you’ve complimented a friend’s conservatory, only to be told that it is, in fact, an orangery, you may want to understand the distinction between the two. You may also be considering whether an orangery may be a better option for your own home. 

Both a conservatory and an orangery offer your home an additional living space, while opening out your home to the outdoors, and both are made largely of glass. A conservatory or orangery can be used for multiple purposes, whether you’re looking for somewhere to sit in the Summer months, or somewhere stylish to dine, overlooking the garden. However, there are a couple of important distinctions between the two that will help you identify which is which. 

What is an Orangery? 

The orangeries of old are, really, where it all started. In the 18th Century, explorers and merchants were traveling farther than ever before, bringing back many exotic treasures from around the globe, including plants.

Unfortunately, plants more accustomed to warmer climes were unlikely to flourish in the harsh British climate.

To overcome this, orangeries were built, usually within the grounds of stately homes. These were huge glass structures in which were housed tropical plants, including – you guessed it – orange trees. 

A good orangery was a status symbol, enabling the owner to show off their wealth through their range of exotic plants and, unlike the orangeries of today, they were built away from the main house, within the gardens on the estate. 

Although the purpose of an orangery is very different in today’s society, a contemporary orangery is essentially a supplementary glass structure, similar to a conservatory, but built in the style of the original orangeries. 

What makes it an orangery? 

Though not always the case, an orangery generally has more brick or timberwork than a conservatory.

However both an orangery and conservatory can be built with a brick base or brick or timber pillars between the frames so this is not the clearest identifier. The key difference between the two, however, is the roof.

Where a conservatory has an all glass roof, an orangery is built with a solid roof (usually flat) with a glass lantern in the centre to allow in more light. 

Should I choose a conservatory or an orangery? 

Ultimately, the decision on which to go for comes down to your own personal preference and the building you already have in place, as well as budget. If you want a new living space for your home, an orangery may be the best option for you as, with the solid roof, they have more of an indoors feel and are more like an extension to your home. However, if you want your new room to be more of an ‘outdoor’ living space, a conservatory may be your better option. Both a conservatory or an orangery, however, can be fully customised to suit your needs perfectly.

Disposing of Double Glazed Windows

The environmental credentials of uPVC double-glazed windows are now well known.

With improved insulation, they help to keep your home warmer and increase energy efficiency as a result.

What is less well-known, but equally important, is that new windows are often manufactured using advanced and environmentally friendly practices, as well as being manufactured from recyclable materials. 

But in order to have the most positive impact from this, it’s important that you dispose of your double glazed windows correctly. 

Recyclable materials

There are two key materials used in your double glazed windows and you’ve probably already guessed what they are: uPVC and glass.

uPVC is widely and easily recycled so as long as you dispose of it correctly, you can rest assured that it will go to good use and not to landfill.

The glass is a little more tricky as the different types of glass have a different chemical makeup and therefore a different melting temperature. It can be recycled, but you have to make sure you take it to the right facility. 

If your windows date back to the 70s or sooner, you may struggle to recycle all of the materials due to the lead paint used. This will need to be disposed of in accordance with strict regulations and you should consult your local authority for guidance to ensure they are disposed of correctly. 

Disposing of the materials

First, remove the window from the frame by unscrewing the hinges.

Then you need to separate the glass from the casement using a hammer and chisel.

Once you’ve separated the glass from the plastic, you then need to identify the best place to take them for disposal. Your local council will point you in the direction of an appropriate facility, usually a building materials reuse centre. 

uPVC windows are a great way to ensure you are doing your bit for the environment. Not only do they help with energy efficiency in the home, but the recyclable materials used and sustainable manufacturing processes, means each window is made and installed with environmentally sound principles in mind.
