DIY Magnetic Secondary Glazing: A Guide
As winter approaches, so do the dreaded energy bills. If you’re tired of watching your heating costs soar while your home stays stubbornly chilly, it might be time to look at your windows. Single-glazed windows are a major source of heat loss, but upgrading to double glazing can be an expensive and disruptive process. Fortunately, there's a simpler, more affordable solution that can make a huge difference: a DIY magnetic secondary glazing kit.
This guide will walk you through everything you need to know about magnetic secondary glazing. We’ll cover what it is, how it works, and the significant benefits it offers, from lower energy bills to a warmer, more comfortable home. You'll learn how to install it yourself with minimal fuss, saving you money on professional fitting costs.
By the end of this post, you'll see how a small investment in a secondary glazing kit can pay for itself in no time. Let's get started on making your home cosier and more cost-effective this winter.
What is Secondary Glazing?
Secondary glazing involves adding a second pane of material, typically a lightweight plastic like polycarbonate or acrylic, inside your existing window frame. This creates an insulating layer of trapped air between the original window and the new pane. This air gap acts as a thermal barrier, significantly reducing the amount of heat that escapes from your home.
Unlike double glazing, which requires replacing the entire window unit, secondary glazing is a non-invasive solution. It’s particularly popular in listed buildings or properties with preservation orders, where altering the original windows is not an option. It's also a fantastic choice for renters or homeowners looking for a cost-effective way to improve their home's insulation without major renovations.
There are various types of secondary glazing systems, from permanent fixtures to removable panels. Among the most popular and user-friendly options is the DIY magnetic secondary glazing kit, which offers an effective and flexible way to insulate your windows.
The Magic of Magnetic Secondary Glazing
A magnetic glazing kit is an ingenious and simple system. It uses magnetic and steel tapes to create a secure, airtight seal between your window frame and the secondary glazing panel. Here’s how it works: one self-adhesive tape (usually the steel tape) is applied to your window frame, and the other self-adhesive magnetic tape is applied to the edge of your clear plastic glazing sheet. When the two are brought together, the magnets create a firm seal, holding the panel securely in place.
This system is incredibly practical. The magnetic seal is strong enough to keep the panel fixed throughout the colder months, providing excellent insulation. When summer arrives, or if you need to open the window for ventilation or cleaning, you can simply peel the panel away. It can be just as easily reattached when needed.
Our kit at Indigo Supplies contains 30 metres of both the self-adhesive steel tape and the self-adhesive magnetic tape, all for just £39.95. It’s a complete solution that provides everything you need to get started on multiple windows.
Key Benefits of a DIY Magnetic Glazing Kit
Choosing a DIY magnetic secondary glazing kit comes with a host of advantages that make it an attractive option for any homeowner.
1. Significant Cost Savings
The most immediate benefit is the reduction in your energy bills. By adding an extra insulating layer to your windows, you can dramatically reduce heat loss. This means your heating system doesn't have to work as hard to maintain a comfortable temperature, leading to lower energy consumption and cheaper bills. With energy prices on the rise, an investment in a secondary glazing kit can pay for itself in just one winter. The cost of our kit is a fraction of what you would spend on professional double glazing.
2. Easy and Damage-Free Installation
You don't need to be a DIY expert to install our magnetic glazing kit. The process is straightforward and requires only basic tools. Because the tapes are self-adhesive, there's no need for drilling, screws, or permanent alterations to your window frames. This makes it an ideal solution for renters or those in listed properties who are restricted from making structural changes. When you move out, you can simply remove the tapes without leaving a trace.
3. Improved Home Comfort
A warmer home is a more comfortable home. Secondary glazing eliminates cold spots near windows and stops irritating draughts in their tracks. The result is a consistent and pleasant indoor temperature throughout your living space. Beyond thermal comfort, it also provides a noticeable reduction in outside noise, creating a quieter and more peaceful home environment.
4. Reduced Condensation
Condensation is a common problem in homes with single-glazed windows, leading to dampness, mould, and potential damage to window frames and walls. By creating a warmer interior surface on the secondary pane, magnetic glazing helps to prevent the formation of condensation, keeping your windows clear and your home healthier.
5. Versatility and Flexibility
The magnetic system is incredibly versatile. You can cut the tapes and glazing sheets to fit any window size or shape, from large bay windows to small, awkward ones. And because the panels are removable, you have complete control. Enjoy the extra insulation during the winter, then easily remove the panels in the summer to let in fresh air. This flexibility is something permanent double glazing cannot offer.
Step-by-Step Installation Guide
Installing your Indigo DIY magnetic secondary glazing kit is a simple project you can complete in an afternoon. Here's a step-by-step guide to help you get it right.
Materials You'll Need:
- Indigo’s Magnetic DIY Secondary Glazing / Fly Screen Kit (includes 30m of self-adhesive steel tape and 30m of self-adhesive magnetic tape)
- Glazing sheet (Polycarbonate or Acrylic, typically 2-4mm thick)
- Measuring tape
- Scissors or a craft knife
- Cleaning cloth and rubbing alcohol or a mild detergent solution
- A pen or marker
Step 1: Clean Your Window Frames
A clean surface is essential for a strong adhesive bond. Thoroughly wipe down your window frames with a cloth and a cleaning solution like rubbing alcohol to remove any dust, grease, or grime. Make sure the frames are completely dry before you proceed.
Step 2: Measure Your Windows
Carefully measure the dimensions of the area on the window frame where you will be attaching the steel tape. Measure both the height and the width. It's a good idea to measure twice to ensure accuracy. These measurements will be used to cut both your tape and your glazing sheet.
Step 3: Cut the Glazing Sheet to Size
Using your measurements, mark the cutting lines on your polycarbonate or acrylic sheet. For thinner sheets, you may be able to score and snap them with a craft knife and a straight edge. For thicker sheets, a fine-toothed saw is recommended for a clean cut. Remember to remove the protective film from both sides of the sheet after cutting.
Step 4: Apply the Steel Tape to the Window Frame
Cut the self-adhesive steel tape to fit the perimeter of your window frame. Peel off the backing and carefully press the tape into place, ensuring it is straight and firmly attached. Apply pressure along the entire length of the tape to activate the adhesive and eliminate any air bubbles.
Step 5: Apply the Magnetic Tape to the Glazing Sheet
Next, cut the self-adhesive magnetic tape to match the perimeter of your glazing sheet. Peel off the backing and apply it to the edges of the sheet. Ensure the tape is aligned perfectly with the edges for a neat finish and a secure seal. Press down firmly to ensure a strong bond.
Step 6: Attach the Glazing Panel
This is the satisfying final step. Align the glazing panel with the window frame and bring it close. The magnets will attract the steel tape, and the panel will snap into place. Press around the edges to ensure a complete and airtight seal all the way around.
And that's it! Your window is now fitted with secondary glazing. Stand back and admire your work, knowing you're ready for a warmer, quieter, and more energy-efficient winter.
