Store products safely before installation

Proper temporary storage protects glass, aluminium, timber, seals and fittings against moisture, distortion and loss. This guide explains how to prepare the storage area, receive the delivery and arrange an orderly handover to the installation team.

Days, or a longer project-dependent period, can pass between delivery and installation. During this time, greenhouse, pergola or outdoor-sauna components are not yet protected by their finished structure. Packaging must therefore not be treated as ordinary stored goods or spread around the site without control.

Safe temporary storage starts before delivery. A level, load-bearing storage area, protection from rain and ground moisture, a clear package order and prompt delivery checks are essential. Instructions on packaging, delivery documents and installation manuals always take priority over general advice.

Pre-installation storage checklist

• Keep the installation manual and delivery information ready before unloading.
• Choose a level, clean and sufficiently large storage area.
• Keep components off soil, standing water and splash water.
• Keep access, unloading routes and manoeuvring space clear.
• Do not load sensitive packages without confirmed stacking approval.
• Check delivery contents, package numbers and visible condition on arrival.
• Photograph and record damage or irregularities in writing.
• Do not remove labels, protective films or orientation markings.
• Store glass, timber, aluminium and small parts appropriately.
• Provide ventilation without exposing the delivery to weather.
• Keep foundation materials separate from product packages.
• Limit access to instructed people and document handover.

1. Prepare the storage area before delivery

Do not decide where to store the goods only when the delivery vehicle arrives. Check in advance how packages will travel from the unloading point to the storage area. Narrow passages, steps, soft ground, low clearances or parked vehicles can cause needless handling. Every extra move raises the risk of impacts, scratches and mix-ups.

Size the storage area so that long packages are fully supported and glass or glazing units can be placed as marked. Also allow a safe working route. Packages must not be positioned so closely that labels can be read only by moving heavy units.

Storage-area requirements

Criterion	Practical approach
Ground	Level, load-bearing, clean and free from sharp building debris
Clearance from ground	Use suitable stable supports and prevent sagging
Weather protection	Protect from rain, snow, persistent damp and strong wind
Ventilation	Allow air circulation; do not seal packages in wet plastic
Access	For authorised people only, not as a general site walkway
Organisation	Keep package numbers visible and mark areas by installation stage

An enclosed indoor space is often helpful, but not automatically suitable. Unventilated basements, damp shell buildings or rooms where plastering and screeding are under way can have high humidity. An open area beneath a loosely placed tarpaulin is not automatically safe either. Wind can lift covers, rain can blow in from the side and rubbing can mark coated surfaces.

2. Receive and check the delivery promptly

Arrange delivery acceptance so that a responsible person can inspect the consignment immediately. Compare the packages received with the delivery documents without prematurely dismantling packaging. Visible transport damage, crushed corners, torn wrapping, soaked cartons, shifted glazing units or missing packages should be recorded straight away.

A signature does not replace condition records. First photograph the complete consignment at the unloading point, then photograph each issue from several angles. Ensure package numbers and labels are visible in at least one image. Follow the stated procedure for reporting transport damage and also review information about guarantees and claims.

Information to document

• Date and approximate delivery time
• Name of the person accepting delivery
• Number and identification of packages received
• Overall view before moving the consignment
• Condition of cartons, wrapping, crates, pallets and edge protection
• Location and type of visible damage
• Unusual moisture or signs of shifting
• Differences between delivery documents and packages present
• Immediate steps taken, such as moving items somewhere dry

Do not dispose of damaged packaging until it is clear whether it is needed for assessment. Alter an identified issue only as far as necessary to prevent further damage or an immediate hazard.

3. Preserve labels, orientation and packaging condition

Arrows, package numbers, centre-of-gravity labels and notices such as this side up, fragile or do not stack are part of the storage system. Do not turn packages simply to save space. Removed labels or cut-open bundles make later identification harder and can lead to components being opened in the wrong sequence.

Open only as much as required for the specified incoming inspection. If a package must be opened, photograph its condition first and retain all markings. Then close it again so that its protection and ventilation remain as close as possible to their original purpose. Do not apply tape directly to painted, powder-coated, glazed or visible timber surfaces.

4. Protect glass, aluminium, timber, seals and fittings

Delivery materials react differently to moisture, point loads, temperature changes and unsuitable support. One storage method for every package is therefore unsuitable.

Glass and glazing packages

Glass is especially vulnerable to point impacts on edges. Store and move glazing units only in accordance with package markings and installation documents. Where upright storage is specified, secure the package against tipping and support it on a suitable base. Do not lean unpackaged panes loosely against walls or other components.

Do not lay glass packages flat merely to save floor space. Do not place profiles, toolboxes or building materials on them. Keep the area clear of grinding work, sparks, mortar, metal swarf and heavily used walkways. For glazing options, the information on material properties is also important; our article on polycarbonate and twin-wall sheets for greenhouses also explains different glazing considerations.

Aluminium profiles and finished surfaces

Long aluminium profiles require even support. Isolated supports placed far apart can encourage unwanted bending. Do not put heavy objects on profile packages or drag components across rough ground. Sand, drilling swarf and small stones can act like abrasives.

Protective films should normally stay in place until the installation step specified in the manual. However, they should not be left under intense sunlight indefinitely without checking the instructions. Product-specific guidance applies. For later use, the guide to caring for an aluminium greenhouse is also helpful.

Timber components

Store timber dry, ventilated and protected from direct weather. Avoid contact with soil, damp concrete or wet walls. Support long components so they cannot sag on one side. An airtight cover can trap moisture already present, while fully open storage can cause alternating wetting and drying.

For outdoor saunas, a clear package order is particularly important because shell, roof, interior-fit-out and accessory parts may belong to different installation stages. Always check the documents for the specific model, for example the Elma S outdoor sauna, the Elma L outdoor sauna, the HC150 barrel sauna or the HC 180 barrel sauna.

Seals, fixings and small parts

Keep screws, connectors, cover caps, seals and installation aids in their labelled bags or cartons wherever possible. Store small parts dry and protected from unauthorised access. Do not decant different screws into one container: similar diameters or heads do not mean parts are interchangeable.

Seals must not be crushed beneath heavy packages or stretched unnecessarily. Keep them away from sharp items, contamination and unsuitable chemicals. If small parts are removed for inventory checks, count them on a clean surface and immediately repack them with their position marking.

5. Control moisture without trapping condensation

Moisture reaches deliveries through more than direct rain. Condensation can form when cold components enter warmer, humid air or when temperatures change sharply in temporarily covered packages. A seemingly waterproof tarp can keep rain out while trapping existing moisture inside.

Inspect the storage area regularly for dripping water, damp ground, damaged covers and condensation. Ensure air circulation without opening packages to wind and driving rain. Do not place heaters directly against components or try to dry damp timber, seal or glazing packages with intense local heat. If a package gets wet: document it, move it to a protected area, have its condition assessed appropriately and obtain product-specific instructions.

Managing moisture in an assembled greenhouse is a separate subject. See the guide to temperature and humidity in the greenhouse.

6. Adapt the storage plan to product and project

A compact greenhouse, a large orangery, a wall-mounted pergola and a timber sauna do not have the same requirements for access, package sequence and temporary storage. First establish the product type, planned position, installation date and installation team. Information about greenhouses and conservatories, saunas and other useful information can support project preparation.

For pergolas, design and placement determine which packages must be accessible first. Compare the guidance on bioclimatic or classic pergolas, wall-mounted or freestanding pergolas and the pergola size guide. The article on bioclimatic pergolas also helps define the concept at an early stage.

For larger greenhouse projects, allow sufficient manoeuvring space for long profiles and glazing. Articles on Victorian greenhouses and planning an orangery offer inspiration and background. They do not replace the delivery documents or installation manual for the ordered product.

7. Keep foundation work separate from stored components

Foundation work creates dust, splash water, cement slurry, metal swarf and site traffic. Do not store product packages directly beside mixing areas, excavations, formwork or cutting work. Fresh concrete is not a general storage surface either. Keep routes clear so wheelbarrows, machines and materials do not have to be forced past glazing or profile packages.

Dimensions, heights, level, drainage and fixings must suit the specific product before installation begins. Use the pergola foundation guide. Whether planning permission or other local requirements apply depends on the proposal and site. In Malta, ask a perit to assess the structure's footprint, height, enclosure, land designation and existing permit conditions with the Planning Authority before work starts. Planning permission for a greenhouse or pergola in Malta requires a project-specific assessment.

8. Organise packages by installation sequence

Space-saving storage is not automatically installation-ready. If the frame package needed first is behind glazing or roof components, the delivery must be moved repeatedly. Create a simple zone system:

1. Zone A: foundation, base or frame components needed first
2. Zone B: load-bearing profiles and main structure
3. Zone C: roof, wall or cladding elements
4. Zone D: doors, windows, louvres or fit-out parts
5. Zone E: labelled small parts, seals and accessories

The actual sequence is determined solely by the installation manual. Do not write directly on visible surfaces. Use separate, securely fixed markers and maintain a package list. Removed parts should be logged immediately or handed to the responsible installer.

9. Handover checklist for the installation team

• Installation manual, package list and order documents are fully available.
• The responsible contact and access to the storage area are confirmed.
• Documented irregularities have been passed on before work begins.
• Packages are clearly labelled and accessible in installation order.
• Glass and long-item packages remain safely in their intended positions.
• Small parts are dry, sealed and clearly assigned.
• Foundation and installation area have been checked separately and kept clear.
• Transport routes are free of debris, plants, vehicles and trip hazards.
• Required local arrangements are complete before installation begins.
• Packaging is discarded only after parts have been checked and assigned.

Common temporary-storage mistakes

• Direct ground storage: Ground moisture and minor unevenness can affect packaging and components.
• Completely sealed tarp cover: It can trap condensation and become a mechanical load in wind.
• Unchecked stacking: Lower packages can be damaged even when the upper layer seems light.
• Laying glass flat: Changing the prescribed orientation is not safe space-saving.
• Removing protective films early: Visible surfaces are then unprotected during transport and installation.
• Mixing fittings: Similar fixings may later be assigned incorrectly.
• Storage in site traffic: Impacts, splashes and unauthorised access often go unnoticed.
• Delayed inspection: After repeated moves, the original delivery condition is difficult to establish.
• Improvised repairs: Tape, cleaning agents or local heat can cause further damage.

Frequently asked questions

Can I store my Bloomcabin product outdoors before installation?

Only if the product-specific documents permit it and suitable prepared weather protection is available. A tarp over grass is not enough. You need a level, load-bearing base, separation from ground moisture, protection from rain and wind, and adequate ventilation. Sensitive glazing, timber and small-parts packages need particular protection. If uncertain, a dry, controllable storage space is the better option.

Should I open every package when it arrives?

No, not automatically. First check the number, identification and external condition. Open packages only in line with delivery and inspection instructions, or where a documented irregularity must be clarified. An unnecessarily fully opened package loses its orderly allocation and possibly some transport protection. If opened, document the contents and resealing clearly.

How long may packages be stored temporarily?

There is no universal maximum period. It depends on the product, packaging, material, storage climate and manufacturer instructions. Keep storage time as short as possible and inspect the delivery regularly. If installation is substantially delayed, ask for product-specific guidance rather than assuming shipping packaging is suitable for unlimited long-term storage.

May I stack greenhouse or pergola packages?

Only where markings or documents expressly permit it. Packaging shape and apparent strength do not reliably show whether it can be stacked. Long profiles, glazing and packages with finished surfaces can be damaged by pressure or point support. When in doubt, store units separately with full support.

What should I do if packaging becomes wet?

Photograph the condition, label the affected package and move it to a protected area without risky changes of position. Do not trap moisture by adding sealed plastic covers. Do not open or dry the package using direct heat before the correct procedure is confirmed. Contact Bloomcabin promptly if there is visible damage or soaked contents.

Can glass packages be laid flat to save space?

Not without an explicit instruction allowing this. Retain the marked transport and storage orientation. Glass needs suitable support and protection from tipping, edge impacts and loads placed on it. Unauthorised flat storage can create stresses for which the package and panes were not designed.

May protective film be removed before installation?

Remove protective films only at the installation stage stated in the manual. Removing them too early exposes surfaces to scratches, dust, mortar splashes and tool contact. Equally, films should not remain under intense sun for unnecessarily long periods contrary to product-specific instructions. The relevant rule is therefore the manual for the specific product.

Where should screws and fittings be stored?

In a dry, closed and clearly labelled area. Keep parts in their original labelled bags or cartons where possible. A separate small-parts cabinet or protected box is useful if the original allocation is retained. Do not keep accessories loose in profile packages or on an open construction site.

What if the foundation is not complete when delivery arrives?

The delivery then needs a separate storage area that does not conflict with foundation work. Do not repeatedly move product packages between excavation, formwork and concrete work. Also check whether the expected storage period and later access remain suitable. Installation should begin only once the foundation and local requirements for the specific project have been checked.

Who should have access to the stored delivery?

Only named people who understand the sensitive packages, safe routes and package order. Children, uninvolved tradespeople, visitors and pets should not have access. Decide who may remove parts, open packaging or move the delivery. This keeps a clear record of when and why a package condition changed.

Which documents should be kept with the delivery?

Keep the order confirmation, delivery documents, package list, installation manual, delivery-acceptance photos, damage notes and relevant communication together. Digital copies protect against loss on site. General company and service information is available under About us; use direct contact for project-specific questions.

Final readiness check

Before the installation date, the delivery should be dry, safe, fully documented and accessible in a sensible order. Recheck packaging, labels, glass position, profile supports, timber packages and small parts. Also inspect the foundation, work area and transport routes separately from product storage.

Do not begin assembly if essential packages are missing, damage remains unresolved or other work still affects the installation area. A short, systematic final check prevents improvised restacking and protects components during the phase when the finished structure does not yet protect them.
