A garden gym all year round: how it behaves in each season

One of the usual hesitations before deciding on a garden gym is thinking it is only useful for a few months a year: fine in summer, poor in winter. This article goes through, season by season, how a module designed for continuous outdoor use, such as Supercubo Home, behaves.

Spring: the ideal starting point

In spring, with mild temperatures, a garden gym works almost without needing to think about the weather: it is the season that asks least of the module’s design and the one in which it is easiest to enjoy natural light and ventilation with no further adjustment.

It is also a good time to install the module, if the project allows: the season leaves room to see how the space behaves before summer arrives.

Summer: where insulation and ventilation are put to the test

In the hottest months, the thermal behaviour of CLT and good natural ventilation make the difference between a pleasant space and one that turns into a heat box. The orientation chosen at the design stage also has a strong influence on how the module behaves during the sunniest hours.

Some people choose to train in the coolest hours of the day during the summer, taking advantage of the fact that the module, being in the garden, makes that change of schedule easy.

Autumn: humidity returns as a factor to watch

In autumn, with more rain and humidity in the air, insulation and ventilation once again play an important role, this time to keep outside humidity from reaching the inside of the module. A good seal at the door, like the one a double-leaf aluminium door provides, helps keep the interior dry and protected.

Winter: where thermal insulation makes the real difference

Winter is when the difference between a module designed for year-round use and a generic shed is most noticeable. The insulation of the CLT and the sandwich-panel roof reduces the cold coming in from outside, allowing the space to remain usable without the extreme conditions of a structure without this approach.

This does not mean a temperature identical to a climate-controlled room in the house, but behaviour notably better than that of an outdoor construction without insulation designed for this use.

Frequently asked questions

Can a garden gym be used in the depths of winter?

Yes, a module with thermal insulation designed for outdoor use notably reduces the cold compared with a shed without this approach, although it does not replace the temperature of a climate-controlled room in the house.

Which is the most demanding season for the module’s design?

Summer and winter are the seasons in which the behaviour of thermal insulation and ventilation is most noticeable; spring and autumn are, in general, easier to manage.

Does anything different need doing each season to maintain the module?

It is worth checking the condition of the exterior timber and the seal of the door periodically, paying a little more attention before the most demanding seasons (summer and winter).

Can summer become a problem if the module is badly oriented?

It can if the orientation was not considered together with the rest of the design; that is why orientation, ventilation and insulation are assessed together before the module is installed.
