Stable Door Modification – £120
A split stable door will allow ample airflow to circulate around the greenhouse and create more comfortable conditions if working within the greenhouse in the summer sun. The lower half of the door restricts any pets or pests from entering the greenhouse. A single door can be upgraded to a stable door at a cost of £100.
Relocating a Single or double door in the greenhouse long side
A double or single door can be installed to any rectangular greenhouse to improve accessibility or suit a garden layout. The cost is roughly 10% of the cost of the greenhouse to account for the extra material required to raise the greenhouse eaves from 5ft6″ to 6ft6″. Please contact our office for an accurate estimate. If you wish to go beyond a single standard door, each additional single door costs £265.00 and a set of double doors £315.00. Please note this greenhouse design requires 6ft 6″ eaves and subsequently will increase the ridge height of the greenhouse too.
Double doors installed into greenhouse gable – £230
Double doors can replace a single door in any greenhouse gable and create a great visual feature. The double doors also improve accessibility for wheelbarrows, tools and garden machinery. Replacing a single door with a pair of double doors in the gable costs an extra £200.00. To install a set of double doors in a blank gable costs £300.
Ventilation can be used to control the temperate and climate of a greenhouse to suit plants that require different growing conditions.The auto vent allow hot air to escape from the roof of the greenhouse and prevent overheating. All Woodpecker Joinery greenhouses come with a number of automatic roof vents as standard. The number is based on the size and model of the building. The roof vents are fitted with the MK7 Bayliss which work independently and have no need for a power source. The Bayliss opening thresholds can be calibrated by a screw winder fitted on the device.
White Painted Finish – Additional 40% of structure cost.
A white painted finish can be applied to any of our cedar greenhouses for an extra 40% of the structure cost. We use a high-quality Teknos paint, with microporous properties which allow the cedar timber to breathe.
Louvre vents can be installed in addition to roof vents to increase air circulation within the greenhouse. Hot air escaping from the greenhouse through the roof vents forces air to travel in through the louvre. The airflow through the louvre vent can be regulated by the angle of the louver blades, thus allowing further control over the airflow and increased control over the greenhouse growing conditions. The louver vent is set in an aluminum powder coated frame and so protected from rust and corrosion.
An alternative to louvre vents is to install casement windows. The casement window is aesthetically more fitting with a traditional greenhouse design, but is not as secure or as effective as a louvre window. Casement windows are fitted with a black antique stay and matching hinges. The stay allows the window to be opened to three different positions.
