11 m² gray-blue Utility garden shed

It all depends on your insurance policy. Your home insurance policy may not cover yourgarden shedas part of your outbuildings.
In some cases, an additional clause and therefore an amendment to your home insurance policy may be necessary.

We therefore recommend that you contact your insurance company if you want to protect yourself from any unpleasant surprises in the event of theft or damage.

What is addiction?

In fact, a garden shed can be considered an outbuilding of your home.

An outbuilding is an external structure located within a certain radius of the main dwelling. If the garden shed is located at a certain distance from the house, without being integrated into it, it will be considered an outbuilding. However, each insurer will have its own criteria, so it is important to check.

Insurance is therefore not mandatory, but it provides coverage in the event of theft or damage.

Steps to follow

Each insurer has its own services and criteria regarding shelter insurance. It is best to inform your insurer when installing a shelter, who will advise you on the best course of action.  

The insurer will be able to offer you various solutions based on the available policies.

To install a garden shed correctly and ensure that it is perfectly level for the stability of the entire structure, it is essential to have a perfectly flat and stable ground surface. Under no circumstances should the shed be installed directly on soil or grass.

Recommended type of support depending on the surface area of the shelter:

• Shelters up to 4.9 m²: they can be assembled and fixed on gravel slabs or concrete corner blocks.
• Shelters larger than 4.9 m²: we strongly recommend laying a concrete slab (foundation) on which the shelter should be installed and secured.
  

Characteristics of concrete slabs:

• Recommended thickness: minimum 10 cm
• Slab overhang: 3 to 5 cm all around the shelter
  

Regardless of the size of the shelter, we recommend reinforcing its attachment to the ground using the Grosfillex anchoring kit to ensure optimal stability, especially in windy conditions.

For more details, please refer to the anchor kit accessory sheet, available in the shelter product sheets.

Yes. Grosfillex PVC garden sheds are designed for year-round outdoor use and to withstand normal winter weather conditions, including sub-zero temperatures.

The materials used retain their mechanical properties in cold weather. When used normally as a garden shed, they provide effective protection for the equipment and materials stored inside.

In accordance with quality and safety requirements, our shelters have been subjected to resistance tests under harsh climatic conditions. For example, a shelter blade successfully withstood an impact test (falling weight of over 200 g) carried out at -10°C without breaking, demonstrating the robustness of the PVC used.

With regard to snow, shelters are designed to withstand snow loads corresponding to normal weather conditions. However, in accordance with usage and safety recommendations, it is essential to:

• 
  Install the shelter on a suitable base (concrete slab or foundation recommended depending on the surface).
  
• 
  securely anchor the shelter to the ground using a suitable anchoring system,
  
• 
  Regularly remove snow that has accumulated on the roof in the event of heavy or prolonged snowfall to avoid overloading.
  

Failure to comply with these recommendations may result in damage to the product and may render the user liable. For optimal use, it is advisable to refer to the assembly and installation instructions provided with the shelter.

Reasons for condensation

Condensation is caused by temperature differences between the outside climate and the inside of the garden shed, and is a consequence of the excellent insulation properties of PVC, which can cause condensation in certain climates.

What should I do to fix this?

• Increase ventilation by adding a ventilation grille to the upper exterior section of the shelter.
• We recommend adding low vents to your garden shed.
• Finally, it is necessary to check that the structure is properly sealed to see if that is the cause of the condensation on the windows.

Installation of an additional ventilation grille in a Grosfillex shelter

Grosfillex shelters come with four ventilation grilles as standard. Adding one or two extra grilles improves air circulation, thereby significantly reducing the amount of moisture that can build up in your garden shed.

Discover in this document everything you need to know to properly install your ventilation grille(s).

Please note that the Grosfillex warranty does not cover damage caused by exceptional weather conditions such as storms, hurricanes, lightning, floods, and hail. Regardless of the damage, whether all or part of the roof is damaged, you should contact your insurance company to claim underyour home insurance policy. 

The steps to follow are as follows:

1. Report the claim to your home insurance company so that an assessor can visit.
2. Provide your insurance company with the original purchase price of the garden shed.
3. Check whether the "new replacement" option is selected in your insurance policy. Please allow five weeks for a new replacement of your garden shed or 12 weeks for replacement parts for your garden shed. For all after-sales service requests, please provide us with the garden shed reference number indicated on your invoice and the references of the damaged parts specified in your assembly instructions. 

Our garden sheds are mainly sold online, and complete product displays are rare.

You have two options:

1. Some retailers may have models on display, so we invite you to call Grosfillex garden shed retailers in your area.

2. Still unsure? Request a blade sample! Use our contact formhere torequest a spare part for the model of your choice and receive a sample blade in the color of your choice.

Discover some essential tips to prevent water infiltration in yourgarden shed.

Our tips for improving the waterproofing of your shelter:

• Check that the blades are properly fitted.
• Check that the concrete slab is the right size.
• Reinforce the seal with silicone sealant.
• Add low vents to your shelter.

The concrete slab must be adapted to the overall exterior surface area according to the model of garden shed you choose.

The concrete slab must be the perfect size for the garden shed: not too small and not too big. If the slab is too big, it can cause waterproofing problems because it will act as insulation to prevent moisture.

To prepare your shelter for moisture, you need to leave a margin of 5 to 10 cm in length and width. This slab must correspond to the external dimensions of your shelter's structure.

If the slab is too large, there may be a risk of fungus and moss growth due to water stagnation. 

Silicone

Silicone will be used to create joints around the outside of the shelter for a smooth and even finish.

We therefore recommend that you use a sealant as described in the assembly instructions.

Are you looking for a solution to store your tools, children's toys, or even your garden furniture during the winter?

A garden shedwill save you space in your home and also solve your storage problems. Now that you've decided to install a garden shed, it's essential to choose the right material. There are various materials available to you.

But what material should you choose for your garden shed?

Why choose PVC?

PVC has many advantages: it is attractive, easy to maintain, environmentally friendly, and quick and easy to assemble. The shelters require no finishing, staining, or painting.
Made from ultra-resistant material, they can withstand heat, extreme cold, and inclement weather.

To maintain your shelter, simply wash it with a water jet (not high pressure) to restore its shine.

The composition of Grosfillex garden sheds 

Our shelters are mainly extruded from PVC (resin) or PMMA (for dark colors dyed in the mass). Some components are made of polypropylene, while the frame is metal and treated against corrosion.
All garden shelters are made from attractive, durable PVC that requires little maintenance and provides you with additional storage space for your home.

The components of your garden shed

You will find the following components when you receive your package:

• The doors,
• The posts,
• The roof,
• Metal parts,
• The panels that make up the structure
• And all the fastening parts, such as an anchoring kit that is offered

The slope of the roof of our garden sheds is 20°/36% and its color is gray-green. However, it is strongly advised not to cover it with asphalt shingles or dark paint.

Discover our selectionof garden shedsand, to organize the interior of these garden cabins, check out our storage shelves.

The garden shedcan be used to store gardening tools and other items that take up space in the house. It can also be converted into a DIY workshop or a place to store the equipment you need to maintain your swimming pool.

Before considering installing your garden shed, it is important to have all the necessary information and answers to your questions.

Is a building permit required?

Depending on its size, you may need to obtain a permit to install your garden shed.

We recommend that you always contact your local town hall andpublic servicesto obtain all the necessary information before purchasing your shelter.
It is also advisable to consult your town's local urban planning regulations to obtain all the information you need about installing the shelter on your property.

There are a few regulations you should be aware of.

-Garden shedswith a footprint and floor area ofless than 5 m²are not subject to any administrative regulations.

-Garden sheds between 5 m² and 20 m² aresubject to a declaration of works when they are installed.
