Storage building H1133-30 non-insulated

No, the laws and regulations prescribe that there must be at least 100 cm between them. A distance of one (non-insulated) or two (insulated) meter is also necessary for assembly.

The storage buildings meet the performance requirements for the fire safety of storage buildings as referred to in the Dutch Building Decree 2003. This means that in the event of a fire, the structure remains intact long enough for it not to collapse prematurely. If you want to increase fire safety for people and materials, we advise you to equip the storage building with a sprinkler system.

This is possible for the H-type storage buildings. You can select this as an option. If necessary, you will receive additional construction drawings. Depending on the size of the storage building the additional man door and / or industrial doors can be installed in the rear wall or in the side walls.

No additional man doors and / or industrial doors can be ordered for the E-series.

All man doors are equipped with a cylinder lock. The roll-up doors have a latch for a padlock (not included). The overhead doors can only be opened manually from the inside. The storage buildings can therefore be entirely closed up.

All our storage buildings can be extended indefinitely with a multiple of 3.0 (E500 storage buildings), 2.7 (H600, H700h and H800h storage buildings) or 3.3 meters (H900-H1000-H1100-H1200 storage buildings). The E500 storage buildings can easily be adjusted to the desired size during assembly by shortening all horizontal parts between the last two frames. The shortest length can also be shortened in this way. The H600, H700h, H800h, H900, H1000, H1100, H1200 series storage buildings cannot be shortened.

The width of the storage building cannot be increased or decreased.

By default, the storage buildings are supplied without gutters and drainpipes. You can optionally order the matching drainage system. The Kroftman drainage system for storage buildings is entirely made of galvanised sheet steel. The system consists of drain pipes on both sides of the storage building with upright pipes (plus final bend) down to the ground. The capacity of the gutter and the number of upright pipes is tailored to the size of the storage building. The standard available colours are pearl-light grey (RAL9022) and anthracite grey (RAL7016).

You can create an indoor porch by simply installing the front wall in the second or third roof truss. You could do the same with the rear wall of course.

Our storage buildings are delivered without an electric opener as standard. Optionally you can order an electric opener (including 2 remote controls) for the roll-up or overhead door

Kroftman storage buildings can always be placed without a foundation. This distinctive advantage allows you to achieve huge savings on the overall project costs. This allows one to place a storage building much more quickly and inexpensively. The storage building can also be placed on Stelcon® sheets, asphalt, pavement and even on compacted earth, gravel or rubble.

Have a look at our special page about the anchoring options.

Kroftman only supplies storage buildings without windows. If you nevertheless would like to place one or more windows in your storage building, you must do this yourself. In that case, keep in mind that the structural calculation is no longer applicable and the warranty on the construction and sheeting will then lapse.

Yes. You’ll then receive extra sheet material to close the door opening.

If you wish to reduce extreme temperatures or condensation you can insulate your building yourself. This is done by installing common insulating panels (such as sandwich panels, Polystyrene, EPS, PIR, Styrodur®, Isover® or Fastfixx®) tightly between the truss tubes. The seams should be sealed with insulation tape or caulking. Ideally the insulation panel thickness should equal the depth of the tubes; 75mm or 50mm. (see construction drawings) Due to the remaining thermal bridges and uninsulated roll-up door/skylights these buildings are less suitable for full heating. Please be aware that the maximum snow load allowance should be reduced with the weight of the roof insulation.

With the E500 series it is possible to build in a different size of roll-up door. We then deliver the entire storage building without a roll-up door so you can order a roll-up door with the desired dimensions yourself.

Due to a different steel construction, it is not possible to install a wider roll-up of overhead door with the H600-, H700h-, H800h- and H900-series storage buildings.

Do you want to build in a higher roll-up or overhead door? Then you need to build the storage building on a stem wall to enlarge the opening for the industrial door.

Yes. To calculate the maximum snow load, you have to subtract the weight of the solar panels from the snow load.

Example: if the snow load for the storage building in question is 1,2kN/m², then the roof can withstand 120 kilos of snow per square meter.

If the solar panels for example weigh 40kg, 80kg remain. In a region where the snow load is less than 0,8kN/m² (80kg per square meter), the storage building can be equipped with solar panels.

The non-insulated storage buildings ventilate at the front and rear under the ridge cap and the gable trim. In addition, all roof seals are equipped with ventilating foam tape. However, the ventilation is not calculated.
The insulated storage buildings have no ventilation openings. You can optionally have a natural or mechanical ventilation system installed.

Ventilation standards are not necessary for storage buildings unless the application prescribes these (for instance storing chemicals).

Yes. You will then receive extra sheet material to seal the opening at the front. Note that the height of the industrial door in a side wall is lower than in a front or back wall.

You can, but the warranty will then lapse. The sheet material has a polyester top coating. If this is covered by an extra layer of paint, the coating no longer offers full protection.

For the H-series, the man door can effortlessly be placed to the left or the right of the roll-up door. And rotating clockwise or counter clockwise.

For the E-series, the man door can only be placed to the right of the roll-up door.
