What’s the difference between an Aspen Lodges Garden Room, and a Summerhouse?

Aspen Lodges Ltd specialise in building premium quality garden rooms and garden offices in the South Yorkshire area. As garden room experts we understand the importance of creating garden rooms that can be utilised throughout the year. In this blog post, we’ll explore the key differences between a fully insulated garden room with ventilated cladding, and an uninsulated summerhouse.

1. Year-Round Comfort:

One of the major advantages of a fully insulated garden room is its ability to provide year-round comfort. Unlike uninsulated summerhouses that tend to be too hot in summer and too cold in winter, a fully insulated garden room ensures a more consistent temperature throughout the year. This creates an inviting space that can be enjoyed regardless of the season, whether it's for work, leisure, or relaxation.

The clue is in the name 'summerhouse'. Summerhouses are designed to be used throughout the summer only, when no heating is required. There'll be problems if a summerhouse is used in the winter when heating is required. i.e. When it's cold outside, the warm heated interior air will form a dew point on the thin uninsulated summerhouse walls which will eventually cause the timbers to rot. Aspen Lodges have replaced several summerhouses for this very reason.

Unfortunately, you can't simply add insulation to a summerhouse to solve the problem, and in some cases it can make the problem worse. i.e. if the warm interior are gets trapped behind the insulation and causes a dew point, the problem could be masked and allowed to fester until extensive structural damage is caused to the timber frame.

Each layer of materials in a properly constructed garden room compliment each other. For example, if a timber frame building is insulated, then there also needs to be an internal vapour barrier to stop the warm heated interior air from getting through the walls and meeting the cold exterior air, and forming a dew point.

An Aspen Lodges garden room wall also includes a breathable waterproof membrane. It's important that it's breathable so that any small amounts of internal vapour can gently disperse into the exterior ventilation layer. If the waterproof membrane wasn't breathable, then it's possible for dampness to become trapped within the walls. The ventilation layer that circulates the building behind the cladding is also critical in the prevention of dampness and allows air to circulate around the building and disperse any dampness that finds itself behind the cladding. If a summerhouse has insulation retrospectively fitted, there'll be no ventilation behind the cladding and it's a recipe for dampness and rot which is obviously not ideal if you're using the building as an office with computers and electrical equipment.

2. Energy Efficiency:

Insulated Aspen Lodges garden rooms are designed to be energy-efficient, which is not the case for summerhouses. For example an Aspen Lodges Garden Room’s wall comprise of 12 individual layers of materials, whereas a typical summerhouse is simply constructed with a single layer of timber cladding. The insulation in a Garden Room helps to retain heat during colder months and keeps the space cool during warmer periods. By reducing the need for excessive heating or cooling, you'll not only save on energy costs but also contribute to a greener environment.

3. Noise Reduction:

A fully insulated garden room with ventilated cladding build by Aspen Lodges offers superior noise reduction compared to an uninsulated summerhouse. The insulation materials effectively absorb and dampen external noises, creating a peaceful and quiet environment within the garden room. Whether you're using the space as a garden office, gym, or hobby room, the reduced noise levels will enhance your overall experience.

4. Versatility and Functionality:

Thanks to the insulation, an Aspen Lodges garden room offers greater versatility and functionality compared to an uninsulated summerhouse. The controlled climate ensures that you can use the space for a wide range of activities, such as a home gym, art studio, or even a guest room. The possibilities are endless, and you can customise the interior to meet your specific needs and preferences.

5. Durability and Longevity:

Investing in a fully insulated Aspen Lodges garden room with ventilated cladding ensures its durability and longevity. The insulation not only protects the structure from extreme temperature fluctuations but also acts as a barrier against moisture, and the cladding ventilation helps prevent issues such as dampness and rot. With proper maintenance, your garden room will stand the test of time, providing you with many decades of enjoyment.


When it comes to choosing between a fully insulated Aspen Lodges garden room with ventilated cladding and an uninsulated summerhouse, the benefits of the former are abundantly clear. From year-round comfort and energy efficiency to improved noise reduction and versatility, an insulated Aspen Lodges garden room offers an unparalleled experience.
