An insulation target is planned by choosing the roof, glass, profiles, floor and ventilation together.
A winter garden is an enclosed-space solution created by choosing the roof, glass façade, profiles, floor, solar control and ventilation together for the period in which it will be used.
If it is to be heated in winter, we handle the insulation and condensation calculation across all components of the project.
In a heated room no single component decides the result; roof, glass, profiles and floor work together.
In a glazed room, summer heat gain is planned too. Shading and opening sections are therefore part of the design.
In an enclosed room, air change is provided by opening glass sections and, where needed, additional ventilation.
We talk through your period of use and choose the components together on that basis.

A winter garden is not an off-the-shelf product; the components are chosen together for the intended period of use. Thermal performance depends on the glass, profile and junction details being chosen together.
If the space will only be used in mild weather, a terrace enclosure may be enough. If winter heating is the aim, insulation, condensation and ventilation are handled across all components of the project.
You see the roof-glass-floor junction and the opening sections in three dimensions before installation.

The price of a winter garden is the sum of the chosen components and varies with the intended period of use; it cannot be given from a ready-made list.

A solution in which the roof and, where needed, the sides are designed together for the space. For heated use, the insulation of the whole envelope is assessed separately.
Read moreGlass panels slide sideways on a horizontal track. When open they gather side by side on the track; glass that folds open is a separate mechanism.
Read morePanels travel along the track and turn to stack at the side. We show the space the parked panels take up in the project drawing.
Read moreGlass panels move vertically by motor. When open, the panels gather at the top or at the bottom depending on the model; we show the remaining opening from the project dimensions.
Read moreThe essential difference between a bioclimatic pergola and a winter garden is thermal insulation. A pergola gives shade and rain protection but does not turn the space into a heatable volume; a winter garden does. That difference drives cost, planning status and how the space works in winter.
Read the guideTerrace enclosure is not a single product but a family of solutions chosen according to need. There are three main approaches: pergola systems that cover only the top, glass systems that close the sides, and full enclosure combining both. If insulation is required the solution becomes a winter garden.

In a terrace enclosure the roof and sides are chosen for the period of use. In a winter garden the aim is an enclosed room; if heating is wanted, the insulation of the whole envelope is planned together.
In a glazed room, summer heat gain is planned too. Solar control, shading and opening sections are therefore part of the design.
Permit and notification requirements depend on the project and on local regulations where it is built. As an enclosed room is being created, we recommend checking with the local authority.
Sliding, folding and guillotine glass are compared for the intended use. Thermal performance depends on the glass, profile and junction details being chosen together.
