Why is ThermoWood® the Best?

Thermowood Greenhouse

ThermoWood® is a special thermally modified timber developed in Finland. The timber is heated treated up to 215 °C to remove all excess moisture. This wood is well suited for outdoor applications where demanding weather conditions are the norm. The key performance features of ThermoWood® over Tanalised timber are:

Improved durability against decay
Resin removed
Improved dimensional stability
Consistent colouring throughout
Reduced equilibrium moisture content

The timber is used extensively throughout Scandinavia for all sorts of interior and exterior construction, cladding and decoration due to it’s good looks and superb resilience to harsh weather.

Oiled Finish as Standard

Oiled Panel

Oiling Wood serves as a protective and nourishing treatment, enhancing its natural beauty while preventing dryness, cracking, and decay. This simple yet effective process not only deepens the wood's colour and grain but also prolongs its lifespan, making it an essential practice for maintaining the durability and aesthetic appeal of wooden surfaces. Its also easy to maintain and reapply when needed.

Autovents as Standard

Greenhouse Roof Auto Vents

Swallow use high quality Bayliss XL Automatic roof vent openers as standard on every roof vent. Even when you're not around your greenhouse will be well ventilated.

Staging

Swallow Greenhouse Staging

Swallow include a length of slatted staging with all greenhouses that is 520mm wide and 745mm high.

Installation Included

Swallow Greenhouses are delivered and installed countrywide for free. You simply order your new greenhouse and it will be delivered and erected in your garden by a Swallow fitting team.

Damp Barrier

Swallow Greenhouse Damp Barrier
