8' x 12' Made to Measure Double Glazed uPVC Greenhouse

Ultimate uPVC Greenhouse 8' x 12' – Double Glazed with Cresting and Finials

Create a substantial year-round growing space with our 8' x 12' Made to Measure Double Glazed uPVC Greenhouse. Manufactured in Bristol using durable, low-maintenance uPVC profiles, this larger greenhouse combines 28mm toughened double glazing with a 25mm multiwall polycarbonate roof to provide excellent insulation, natural light and plenty of usable growing space.

The generous 8' x 12' footprint makes this an excellent choice for serious gardeners who need room for staging, shelving, propagation, vegetables, larger plants and overwintering tender or frost-sensitive plants.

Double Glazed Greenhouse for Year-Round Growing

A major advantage of this greenhouse is its 28mm toughened double-glazed sealed units. Compared with conventional single greenhouse glazing, the insulated units help reduce heat loss and create a more protected environment during colder weather.

This is particularly valuable for gardeners who want to extend the growing season or use their greenhouse throughout winter.

If greenhouse heating is required, the improved insulation helps retain more of the heat being produced, making the greenhouse much more suitable for controlled winter growing than a basic single-glazed structure.

Ideal for Protecting Plants During Winter

The insulated construction makes the greenhouse particularly useful for overwintering tender and frost-sensitive plants that require greater protection when outside temperatures fall.

Depending on their individual temperature requirements, the greenhouse can provide a protected environment for:

• Citrus plants
• Tender and young plants
• Frost-sensitive plants
• Pelargoniums and geraniums
• Tender herbs
• Seedlings and young plants
• Overwintering container plants
• Selected Mediterranean and exotic plants

Please note: double glazing improves insulation but does not guarantee a frost-free temperature. Plants requiring a particular minimum temperature may still require a suitable thermostatically controlled greenhouse heater during prolonged cold weather.

Made to Measure uPVC Greenhouse

Although this greenhouse is based around the popular 8' x 12' size, it can be made to measure to suit the available space and your individual requirements.

This provides far greater flexibility than a standard off-the-shelf greenhouse and is particularly useful when working with an existing base or a specific garden layout.

Made-to-measure manufacture is suitable for:

• Existing greenhouse bases
• Replacement greenhouse projects
• Patios and paved areas
• Spaces alongside garages or garden walls
• Unusual garden dimensions
• Customers requiring a specific width or length

28mm Toughened Double Glazing

The greenhouse sides use 28mm toughened double-glazed units, providing excellent natural daylight while helping improve thermal performance.

Toughened safety glass provides additional strength and durability, while the double-glazed construction gives the greenhouse a much more substantial feel than lightweight single-glazed garden greenhouses.

25mm Multiwall Polycarbonate Roof

The greenhouse is completed with a strong 25mm multiwall polycarbonate roof.

Multiwall polycarbonate is lightweight, durable and helps diffuse incoming daylight while providing better insulation than thin single-sheet greenhouse roofing.

Roof and Side Ventilation

Good ventilation is essential during warmer weather and helps provide greater control over the greenhouse environment.

Ventilation options include:

• Roof Vent: Helps warm air escape from the upper part of the greenhouse.
• Lockable Side Vent: Provides additional controllable airflow.

The combination of high and low-level ventilation helps regulate airflow and temperature as growing conditions change throughout the year.

Extra Growing Space with an 8' x 12' Greenhouse

The generous 8' x 12' internal area provides enough room to create a highly practical greenhouse layout.

The additional width allows staging or growing areas to be positioned along both sides, while the 12' length provides considerably more capacity for larger plant collections.

The available space can be used for:

• Greenhouse staging and shelving
• Tomatoes and other greenhouse vegetables
• Seed trays and propagation
• Larger pots and containers
• Overwintering valuable plants
• Taller greenhouse plants
• Separate propagation and growing areas
• Heated winter growing

Low-Maintenance uPVC Construction

The greenhouse is manufactured using strong uPVC profiles, providing a durable and low-maintenance alternative to traditional timber greenhouse construction.

uPVC does not require routine painting or staining and is easy to clean, making it particularly suitable for a greenhouse intended for long-term, year-round use.

Secure Lockable Greenhouse Door

A substantial entrance door with a lockable handle and heavy-duty hinges provides secure and convenient access to the greenhouse.

Because the greenhouse is made to measure, the configuration can be selected to work with your garden layout and planned internal growing space.

Decorative Cresting and Finials

Traditional roof cresting and finials provide an attractive finishing detail, helping this larger greenhouse become a genuine feature within the garden.

125mm Regency Guttering

The greenhouse incorporates 125mm Regency guttering for effective rainwater management.

Collected rainwater can be directed away from the greenhouse or potentially connected to suitable water storage equipment for reuse around the garden.

Heating an 8' x 12' Greenhouse in Winter

For plants that need to remain above a particular minimum temperature, a suitable thermostatically controlled greenhouse heater can be used during colder periods.

The benefit of the 28mm double glazing is that it helps retain heat more effectively than conventional single greenhouse glazing. This is particularly useful with a larger greenhouse where maintaining winter temperatures efficiently becomes increasingly important.
