Greenhouse Optional Extras Available
Additional roof vent, louvre or casement window
Roof vent with Auto Bayliss
Bayliss Autovents have the lowest failure rates in the industry and are manufactured to last. Each autovent is guaranteed for two years against faulty manufacture. They work on solar power only, using no other source of energy.
They are made to last. Aluminium, stainless steel and brass together with a small volume of wax and plastics are used in their manufacture.
Six blade louvre with aluminium frame
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 louvre blades, thus allowing further control over the airflow and increased control over the greenhouse growing conditions. The louvre vent is set in an aluminium powder coated frame and so protected from rust and corrosion.
Casement window with black antique stay and hinges
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 at creating air circulation as a louvre window. Casement windows are fitted with a window stay and matching marine grade stainless steel hinges. The stay allows the window to be opened to three different positions.
Stable Door Modification – £250
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 £250.
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 5ft 6″ to 6ft 6″. Please contact our office for an accurate estimate. If you wish to go beyond a single standard door, each additional single door costs £250.00 and a set of double doors £500.00. 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 – £250
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 £250.00. To install a set of double doors in a blank gable costs £500.
