Deciding whether to have your garden room insulated is one of the easier questions you will be asking yourself when designing your garden room. To put it simply, no matter what you’re going to use the space for, as long as you plan on using your garden room throughout the year, then it will need to be insulated for you to enjoy it comfortably from season to season. 

What is an insulated garden room?

A fully insulated garden room has additional material in the walls, ceiling, and floor that help to prevent the loss of heat and intrusion of sound. At Crane Garden Buildings we do this by adding a breathable membrane between the studwork in the walls as well as rockwool insulation being trapped in the cavity between the outer wall and the inside lining. As many of us know, the majority of heat is lost through the roof of a building. Our insulated garden rooms have a 4-tier lining and insulation process that helps to contain heat inside the building, this includes the roofing material you choose, the ply layer, the insulation board that fills the cavity between the ply layer and the next layer which is the internal pine matchboard tongue and groove lining. The floor is insulated in the same way.

Why have an insulated garden room?

The main reason we offer fully insulated garden rooms is that their purpose requires them to be used all year-round. Through the colder months the insulation will play a crucial role in keeping the inside of the building easy to heat, warm, and free from mould.

In some cases, customers are choosing a garden room instead of having a traditional brick-built extension onto their home which means the garden room should be as versatile and functional as any other room inside the home.  

The benefits of an insulated garden room

Year-round use 

Ultimately, the biggest benefit of choosing an insulated garden room is that you can use it for 12 months of the year. It can be easily and efficiently heated in the autumn and winter months, and equally it will be kept from getting too hot during the summer. That means there’s one less excuse why you can’t do your workout or invite your extended family round for dinner over the weekend. 

Cost-efficient

As a garden building that you want to be able to use through the winter months, it will need to be heated from the inside for it to be a comfortable place to spend your time. The insulation will be key to ensuring the heat from your electric radiator is trapped inside the building, so you can look out onto your sparkling garden on a crisp winter morning and enjoy your cup of tea in the warmth.

Prevents mould

If you choose to have your garden room insulated, this will help to prevent any soft furnishings, fabric, and other delicate materials like books from getting damp and developing mould. Keeping the moisture content in the air at a minimum will make it feel cosy and warm through autumn and winter.  

Reduces noise 

As well as trapping in heat, insulation will also provide an acoustic barrier to sounds made inside and outside of the garden room. This is particularly useful if you’re used to entertaining guests where there will be lots of chatter, or if you like to play loud music while you workout or like to play your own musical instruments. This additional benefit is why we recommend lining and insulation to anyone looking to use their garden room as a place to entertain or as a music studio. 

Our garden room features & considerations

Internal Lining

In order for our garden rooms to include insulation, they also come with an interior lining on the ceiling and on the walls. Not only does this give it a finished look, it creates the cavity for the insulation to go into as well as adding another layer to help trap in heat. Our internal linings are solid pine matchboard which you can choose to leave natural or have painted for a more polished look.

Double Glazing

Another area where your garden room could lose heat is through the windows. A fully insulated garden room will require double glazed windows, the two glass panes will create a cavity of air that will act as a natural insulator. 

Opening Windows

Whilst we try and insulate our garden buildings as best we can, we also have to consider the ventilation. Rooms, whether inside your home or a separate building, need to breathe. If you are choosing an insulated building, we would also recommend choosing windows that open. This option does come as standard on some of our buildings, but is an optional extra on others. 

Electric Pack

When choosing a garden room that you plan to use through colder months, it’s going to be beneficial to have a heat source inside your garden room to make sure it’s warm and cosy when you would like to use it. We offer a basic electric pack as an optional extra on many of our garden rooms which includes 4 double sockets which you could plug an electric heater into. Alternatively, we can add a thermostatic wall heater with digital display as an add-on to our basic electric pack.

Maintenance is minimal. It’s recommended that the roof is kept clean from any build up of leaves, debris, and moss especially over the winter months. The same applies to the windows, they should be cleaned regularly to prevent any decaying debris eating away at the paint and woodwork. Always check for any damage to the roof or cladding which could potentially let damp in. It’s also good practice to open the windows every now and then to ensure there is sufficient ventilation inside which will also help to prevent any mould developing.
