Are Garden Buildings Warm Enough for Winter?

You Won’t Freeze With The Garden office

A question repeatedly asked is, will my garden room be warm enough in the winter months? The short and simple answer is yes! Here’s why.


We have thought of it all when it comes to keeping our garden rooms warm in the winter months. In fact, our garden rooms are intended for year-round-use which means that not only will they be warm enough during the colder months but cool during those sweltering summer days. As the winter draws ever nearer let’s focus on how your garden rooms will stay warm.

Let’s start with U-values. Firstly, what are U-values? U-values, also known as thermal transmittance is the rate of transfer of heat through a structure. The lower the U-value, the better your garden room will be insulated. Our garden offices are extremely effective against heat loss with U-values on our doors and windows, walls, roofs and floors not exceeding 1.4.

Double Glazing

We use the industry’s leading providers in insulation and double glazing to promote excellent thermal retention. Our floors, walls and roof panels are all filled with high-quality polyurethane insulation. Our doors and windows are also fitted with a top of the range double glazing, Pilkington KTM Optiwhite.

Well Insulated

We construct our garden buildings on a series of structurally insulated metal panels. These metal panels are rust-resistant and allow for the building and ground to be separated. This then allows for airflow beneath the building and the prevention of moisture rising. All of this combined improves the buildings thermal efficiency.

Feel the Heat

As standard, all of our buildings come with a free-standing oil-filled radiator. As well as your standard options, we also offer add-on heating options including wall-mounted radiators, underfloor heating and air conditioning. It’s important to note that due to the exceptional thermal efficiency of our flooring, underfloor heating is not essential.

Whether you’ll be using your garden building as your home office or as a space to retreat to away from the home, you can rest assured knowing that you’ll be able to use your garden room all-year-round, including the icy-cold winter months.
