Yuzet Shed Insulation 1.2m x 25m Review
This Yuzet Shed Insulation reflects 95% of radiant heat back into the building making it effective for use in sheds, summerhouses and even caravans. The product has a layer of corrosion resistant foil, backed by a multi-layer air bubble film and has a total thickness of 4mm.
The shed insulation is available in a range of sizes. I bought the 1.2 metre by 25-metre roll, which provided a total of 30 sq. metres. This was plenty to insulate a small summer house with some left over that I can use on other projects.
The shed insulation was easy to install using a staple gun. I allowed some 50 mm overlap between sheets and taped over the joints with aluminium foil insulation tape. The whole job was completed in an afternoon.
The result of using this insulation was very effective. The summer house is much warmer than previously and if heated up with a fan heater holds the heat much better. The shed insulation should also keep the summer house cooler in summer which will be great.
This was a simple solution to insulating my summer house and making it usable all year round. It’s the best shed insulation for the money!

The results have proved effective and this is an excellent choice if you are looking for the best shed insulation on the market,

Shed Insulation Buying Guide
With property at such a premium in the UK, many of us are turning to our outdoor buildings to provide extra space. Of course, the British weather doesn’t make this easy. Our sheds and summer houses are often roasting hot in summer and below freezing in winter.
So, to really get the most out of your shed, summer house or other outbuildings, you will need to insulate them. This is simple to do and will allow you to create a brand-new room that is usable all year round.
If you are a keen gardener, you will also appreciate being able to retreat to a cosy shed to warm up every so often. In addition, insulation can also be used in sheds and greenhouses to protect plants from freezing conditions.
Even if you do not want to spend time in your shed in winter, your tools and garden furniture will appreciate being kept in a warm, dry environment over the coldest months, so it is worth insulating your shed to protect any items you store.
For most outdoor spaces, foil backed compression insulation is the most cost-effective and easy to install option. This type of shed insulation will keep your outhouse warm and dry and is safe to use with electrics. The insulation comes on a roll and can be cut to size. It requires no building expertise and can be fixed with a staple gun. Using this type of shed insulation can help you go from freezing shed to cosy outdoor space in less than a day.
The shed insulation uses two technologies to keep rooms warmer. Firstly, the trapped air in the bubble layer provides insulation. Secondly, the foil layer reflects heat back into the room. The foil layer also helps keep buildings cooler in the summer by reflecting the sun’s heat away.
Using this type of shed insulation will reduce heat loss and, combined with a heating source, can turn an outbuilding into a usable room in the winter.
This type of shed insulation is easy to install. The insulation can be cut to size and fixed with a staple gun with a slight overlap. Remember to apply a decent amount of tension when stapling and to do it at 50 to 100 mm intervals. Once it is fixed you can trim any excess and seal the joins with aluminium foil Insulation tape.
Do I need to provide ventilation if I insulate my shed?
Yes, some ventilation is required. Often, sheds are quite draughty, so the problem is sealing them rather than providing ventilation. However, if your outbuilding is well sealed you should provide ventilation to allow fresh air in and moisture to escape. As warm air rises, in most cases, providing a two-inch gap between the ceiling and the insulation will suffice. This will avoid moisture build-up and prevent ceiling timbers from rotting.
I have insulated my summer house which has made it warmer, but there still seems to be a lot of heat loss. What else can I do?
Often sheds and summer houses are quite draughty due to their construction allowing for gaps which the wind whistles through. In addition, most sheds are single glazed, often with acrylic rather than glass, which allows a lot of heat loss. A lot of heat is also lost through the floor.
A draughty door frame can be improved by using some insulating strips. These are tacked to the inside of the frame and form a seal when the door is shut.
Foam filler can be used to seal any gaps around window frames or elsewhere in your summer house.
To reduce heat loss through windows you can apply a special secondary glazing film directly to the windows. Even more effective are secondary glazing kits which are acrylic or polycarbonate panels that are held in place with fixing strips or magnetic tape.
For a quick fix to insulate the floor you could put down a breathable membrane and cover this with an offcut of carpet. You can also insulate your shed floor by installing a thin layer of insulation board and covering it with OSB to protect it.
