LoftZone StoreFloor is suitable for almost all lofts, new and old, including cut, purlin and truss-roofed types. It’s frequently fitted in both houses and commercial buildings, and is the only product that has official approval for use in new-build properties in the UK. Your joists (which span across the floor of your loft) will be need to be made of wood and be at least 32mm (1.25″) wide.
For our 1.2m metal Cross-Beams to fit, your joists should be either 400mm or 600mm apart on average (measured from the centre of each joist to the centre of the next one – not the distance in-between them). This covers the vast majority of UK lofts. Because the Cross-Beams slide along the top of the Tri-Supports, they have a tolerance of 75mm in either direction, which helps if your builder fitted the joists only roughly in the right place! In fact, this is one of the features that makes LoftZone so easy to fit, and much faster than using timber or plastic supports alone.
A very small percentage of UK houses however have joists that are 450mm apart, so for these, we have a specially-designed 1.8m Cross-Beam, and associated kits, which can be purchased from this website.
From a StoreFloor perspective, the height of your joists doesn’t matter, and in most UK houses they are approximately 100mm (4″) or 75mm (3″) tall, which is fine. If yours are shorter than that, then we advise reducing the loading you put on StoreFloor. In the very unusual case that your joists are less than 50mm (2″) tall, then we would not advise using your loft for storage.
Yes, thousands of people have fitted StoreFloor into their own homes. The parts are lightweight and sized to easily fit through most loft hatches. They are simply screwed to each other and into the joists. Loft boards to fit on top are a bit heavier, typically 5kg each, but are still an easy DIY job. You can see our installation guide here. Note: to fit StoreFloor, we recommend the use of an electric cordless screwdriver.
Nonetheless, if you would like someone else to fit this for you, then you can find your nearest installer by entering your postcode into the field at the bottom of this page.

The StoreFloor Cross-Beams are 1150mm (about 45″) long. They span over 3 or 4 joists (depending on your building’s joist separation) and have an easy sliding adjustment, in case your joists are not spaced regularly (most aren’t!). The Cross-Beams rest on top of the Tri-Supports, where they can butt up against each other, or be positioned a few inches apart.
The StoreFloor Tri-Support and Uni-Support are both 279mm (about 11″) tall, and rest on the top of the joists. This is sized to allow the full depth of modern insulation levels plus an air gap above the insulation and below the boards. This air-gap is there to allow ventilation, to remove any possible moisture build-up on the underside of the boards. Beware any products which don’t provide this essential air-gap!
Boards are standard tongue and groove chipboard flooring, measuring 1220 x 325 x 18mm.
The StoreFloor parts have been designed to be very strong but also very light. The 1.2m Cross-Beams weight around 1.2kg, the Tri-Supports around 250g and the Uni-Supports around 100g. Hence, the structure to raise a floor of 13m2 (a Medium kit, out best seller) weighs only 33kg, or 2.5kg per square metre.
Boards are heavier. These are discussed in more detail in our post about which boards to choose, and weigh around 12kg/m2 (chipboard) or 7kg/m2 (OSB or plywood).
The most common loft boards used for DIY in the UK are 1220 x 325 x 18mm P5 tongue-and-groove chipboard loft boards, in packs of 3. These are the boards which we sell with our kits online in our store.
But both OSB and plywood are also used and have some advantages. You can read all about these in our blog post on the subject.
Most people would like to board their whole loft, but you don’t have to. StoreFloor is modular so you can start small and build more later when your storage requirements go up. Most people choose a square or rectangular deck, or an L or T shape near the hatch. Some people have more than one deck, on either side of the hatch. Don’t board right up to the eaves though, as you’ll want to keep a gap there for ventilation.
No. StoreFloor is built up in sections, 1 square metre at a time. So you can build part of your deck – on one side of the hatch for example – and then transfer your possessions on to your new deck before creating the next part of your StoreFloor.
We sell a number of standard-sized kits, from 3m2 (32 sq. ft.) to 52m2 (576 sq. ft.). If you’d like to build a floor that isn’t one of these sizes, then we have a handy configurator tool on our shop’s front page, which you can use to work out the precise number of parts you need, and buy those individually. Note that we measure decks in multiples of 1.2m in each direction, as that is approximately the length of our regular Cross-Beams and of standard loft boards. If you’d like to build a deck that isn’t an exact multiple of 1.2m, then that’s possible; we’d recommend you buy enough parts for the next 1.2m up, and then cut the beams and/or boards to suit.
The StoreFloor system consists of the recycled plastic Tri-Supports (the triangular parts) and the galvanised steel Cross-Beams. These, on their own, provide a strong deck. The Uni-Supports (the vertical legs) are there to provide extra stiffness, to carry higher loads and/or for use when you are intending to access the deck frequently.
We provide one Uni-Support for every second Cross-Beam in our kits. It’s usual to place the Uni-Supports evenly underneath the deck, or you can concentrate them in the area which is likely to get the most loading. For storage of up to 25kg per square metre and infrequent access by one person, this number of Uni-Supports is sufficient and most of our customers do not order any more.
If you wish to have a higher load on the deck, or walk upon it frequently, then we advise one Uni-Support fixed under every Cross-Beam, to provide additional stiffness and to spread the load. Additional Uni-Supports are available to buy from our website.
We recommend 4x40mm wood screws. We supply these with all our StoreFloor kits and, if you buy the boards from us too, we supply enough for the boards, too. Our screws come in packs of 200, so there are usually plenty left over.
(Note that if you buy individual StoreFloor parts, not complete kits, then screws are not included however).
Every StoreFloor Cross-Beam, Tri-Support and Uni-Support need two screws each. Each loft board needs a minimum of 3 screws each, though you may choose to use up to 6 screws per board for added strength if you wish.
The Tri-Supports, by their triangular design, overhang the joist in each direction. Sometimes, e.g near the hatch or a wall, this isn’t wanted. So in these cases, we’d recommend putting a Uni-Support at the end of the row of beams. But make sure that you put a Tri-Support on the next-nearest joist, as this is the main load-bearing part. There is a photo of this here.
Loft boards in the UK (including the ones we supply) are rectangular, with a tongue-and-groove along each long edge, so that you can slot one board into the one next to it, for added strength. In addition to this, before LoftZone was invented, people used to stagger the boards when they laid them, so that each board ended half way along the long edges of the two boards next to it. You can see a picture of this by looking at our 1.8×3.6m kit with boards on our shop.
The physics of this is that joists can be unevenly spaced in a loft, and if the short end of a board doesn’t rest on a joist, it doesn’t have a tongue-and-groove on that end, so could sag if someone stepped on it. The risk of this happening justifies the extra effort of cutting boards at the ends of each row.
But this is not an issue with StoreFloor, since we recommend that you place our steel Cross-Beams 610mm apart (for loft boards that are 1220mm long) so that they do indeed screw into a Cross-Beam and are supported by it, and there is no risk of the ends of the boards sagging.
Hence there is no benefit in staggering loft boards when you use LoftZone StoreFloor, and most people choose to avoid going to the extra effort of cutting boards in half and doing so, unless you are using one of our kits which are 1.8m wide, in which case you have to anyway, since loft boards are only around 1.2m long.
StoreFloor is indeed sometimes used for access, e.g. to create walkways or crawling spaces above the insulation for people who need to maintain boilers, water tanks, solar inverters, MVHR or aircon units, etc. You can see a photo a very long access walkway being built in a school on our Flickr page, and builders also fit it into new houses, too. The usual usual minimum width of the walkway is 1.2m (the width of standard loft boards).
However if your walkway is only going to be one board wide, then please note the following: The LoftZone plastic supports provide super-strong vertical strength. One of the design requirements of StoreFloor was to minimise parts, in order to speed up installation, and this was achieved by using the interlocking boards of a normal StoreFloor deck to provide the lateral stability. For any deck that is at least two loft boards wide, then it is very rigid horizontally too, but if you’re only going to use one board’s width then that board will not have another board to push up against and so there may be a small amount of lateral instability. The deck won’t topple over, unless the lateral force was strong enough to rip all the screws out (!), but it may have a little “wobble”. This is easily fixed, either by having a wider walkway, or if you don’t want that, then we recommend that you use extra sections of timber to brace the deck to the joists from time to time.
We don’t recommend that you use StoreFloor to support a water tank, for the following reasons:
The loft boards we sell are not moisture-resistant, as you generally don’t need these in a loft. If you have a damp issue in your loft then this could affect the whole timber structure so we would recommend that you solve the damp problem before fitting any boards.
For more general information about loft boards, please see our page on which boards to choose.
We would encourage you to post your own photos on these sites once you’ve fitted the deck, to help other people see what it’s like!

The Steel TrussShelf is designed for lofts of a trussed-roof construction. You’ll have a trussed roof if the timbers are arranged in a V- or W-shaped pattern, as shown in the photos on the TrussShelf page. This is how most UK houses have been built since the 1990s. It is possible to fit the Steel TrussShelf if one side of the V- and W- is vertical, but if you don’t have these V- or W-shapes in your loft at all, then alas, this product isn’t for you.
Additionally, our product only works in houses where the spacing between each truss, measured from the centre of one truss to the centre of the next one, is about 600mm (or 24″), which is what the vast majority of new build houses have. Builders often often don’t fit trusses very accurately, so we allow for up to 30mm variance, e.g. your trusses can be up to 630mm apart. Because each panel is designed to slide over the top of the one next to it, it doesn’t matter if your trusses are a little bit less than 600mm apart in places.
A minority of trussed roofs have a different spacing (usually 400mm) between the trusses. If that is the case in your home, then we don’t recommend using a Steel TrussShelf, since although it will work, each shelf panel will overlap more than half of the shelf next to it.
The exact dimensions of the flat part of the TrussShelf panel is 660mm (between the trusses) and 610mm at right angles to that.
There are no regulations that we are aware of for loading limits for truss shelves. Loading calculations for the trusses that are published are for the weight that the trusses have to carry from above (such as the tiles), and this is estimated at 68.5 kg per square metre, according to BS5268 (Part 3).
Although LoftZone’s shelves are very strong, we recommend storing no more than 12kg of items on each shelf. If you are concerned that your truss roof construction is too weak to take 12kg per shelf, then we recommend that you consult a structural engineer before purchase.

StoreFloor is extremely strong and LoftZone is the only raised loft floor manufacturer to have put its products through robust accelerated lifetime tests in extremes of temperature beyond those normally found in the UK. Even in these conditions, our StoreFloor deck survived loads of over 500kg per square metre, without failure, making it far stronger than the joists it is screwed on to.
Well, this is a question we can’t answer online, as every house is different! But we can give some general guidance to help you make your own decision.
The British Standard for modern truss-roof houses requires that the loft floor be able to hold a permanent load of 25kg/m2 (e.g. for storage) and a temporary point load of 90kg, without the joists bending and causing cracks in the ceiling below. Bear in mind that this is a minimum strength and only for modern truss-roof houses. Your house could be different and many (especially older) houses are much stronger.
Another regulation, for all buildings since 2015, is called CDM 2015, and this mandates that a loft must be strong enough to safely carry person(s) walking around, e.g. for any maintenance that is needed in the future.
Also, in addition to being strong itself, StoreFloor ensures that any loading is shared across several joists in your loft by forming a lattice-beam type of structure. (In that respect, it’s similar to the old-fashioned way of strengthening a loft by cross-battening with timber, but it’s much less heavy than doing that). This therefore increases the loading that your joists would otherwise be able to take.
The LoftZone parts are designed to be very strong but also very light and you can choose boards of different weights (see the FAQ on the weight of the StoreFloor parts).
Nonetheless, StoreFloor is only intended for storage and occasional access, and we recommend that you don’t overload your joists. If you do, they may bend under the weight and cause cracks in the plasterboard ceiling below. (It’s very rare for a joist to completely snap, you’d have to put a lot of weight in your loft to make that happen).
To summarise then, and to be on the safe side, unless you know that your joists are stronger, we recommend loading your loft flooring with no more than 25kg of stored items per square metre, plus the weight of one person accessing them. And if you think that your loft is particularly weak, then choose boards that are less heavy than chipboard (we discuss options for these here). We have provided this 25kg/m2 guidance since we first launched StoreFloor, and now, after tens of thousands of installs, no one has come back to us to say that their ceiling has been damaged by overloading.
Remember that all houses are different though, and it is your responsibility to load your deck sensibly. If in doubt, please consult a structural engineer.
Most new-build houses now come with a 10 year warranty, underwritten by companies such as NHBC, Premier or LABC. If LoftZone products were fitted by your builder as a paid-for option, then they will usually be covered under this warranty, because the warranty typically covers the materials and the labour of the items fitted by the builder.
But if the LoftZone products were not fitted by your builder, then they won’t be covered by the warranty for the house. Neither will they affect the warranty – this is a common misconception – the warranty only affects items the builder put in, so anything you fit afterwards is irrelevant. You can see a letter that NHBC sent to one of our customers below, which explains this. A LoftZone customer also contacted Premier Guarantee who told them “Boarding your loft will not affect your warranty. Your warranty will only be affected if you were to make alterations which would damage the structure of the build and cause a claim.”
Moreover, LoftZone has a BBA Certificate for StoreFloor. BBA is the UK construction industry standard and is required for all building products for new-build houses. So if your builder tells you that the loft should not be used for storage, that was because in the past, there were no BBA-approved products. But now there are, and so StoreFloor can indeed be fitted to houses, including new-builds. You can download our BBA certificate via this page.
Of course, you need to be sensible. If, for example, you overload your StoreFloor so much that it causes the ceiling below to bend slightly and crack, you can’t claim for the damaged ceiling under your warranty. But if you use our products as designed, and something else goes wrong with your roof, loft or ceiling, then the builder will still need to fix anything they built wrongly in the first place.
It’s worth remembering that tens of thousands of new-build home owners in the UK have had StoreFloor fitted, it’s a very common option in houses that often don’t have much storage space elsewhere.
You will usually receive your items within one week of order, and often faster. However please note that a few deliveries are being delayed owing to Covid-19. If your order is urgent, let us know and we’ll do our best to speed things up.
We use Palletways (the UK’s largest pallet network) to deliver kits with boards as well as our XL and XXL kits without boards. All other kits and parts without boards are delivered by Fed-Ex or UPS. All of these companies are quality, reputable couriers and the vast majority of shipments are delivered rapidly and without any problems. Fed-Ex and UPS will deliver to your front door whilst Palletways, in common with all pallet companies, will deliver to your kerbside / the front of your drive.
You can also collect from our warehouse in Leicestershire (postcode LE9). Please contact us to book in your collection.
We ship worldwide; and if you are outside of Europe, you can buy on our international website, www.loftzone.com.
If you’d like to know where your shipment is during transit, then the best way is for you to check this out using the tracking number online. Fed-Ex, UPS (or their partner, DSV) will send you the tracking number by email as soon as we generate the shipping label. Sometimes this email may go into your spam folder, so please check there if you can’t find it. We pay for a service where Palletways should phone you once your order reaches the local delivery depot, to book in delivery with you. We recommend that you pick a date when you will be at home and able to unload the pallet.
Finally, please note that our warehouse is closed between Christmas and New Year every year, so any orders received in that period will be dispatched in early January, in the order that they are received.
All StoreFloor kits are shipped at a flat rate within the UK of £12 (Monday-Friday) or £25 (for the rest of Europe), regardless of how many kits you buy. Kits with boards can only be sent to mainland England, Wales and southern Scotland, owing to their weight. You can however buy boards from any local DIY store.
Loft ladders are sent with free delivery.
If you are just buying some plastic supports, the delivery cost for these is £5.
If you are collecting your order from our warehouse in Leicestershire, then there is no delivery cost. Please contact us to book your visit. We will also refund any delivery cost you paid online via our website when you book in your collection.
If you are from outside of Europe, please use our international website, www.loftzone.com.
LoftZone parts are shipped in cardboard boxes. Cardboard is widely recycled via your local council, though you can also use these boxes time and again before recycling them.
If you order a kit with boards, it will usually be delivered on a wooden pallet. Pallets will have been used several times before in the courier network and can be reused time and time again within the transport industry; search online for your local pallet collection or recycling company. Local tradespeople will often also collect pallets via apps such as Olio, Nextdoor, Facebook Marketplace or Gumtree.
Pallets can also be recycled but only if the pallet cannot be used reused and has reached the end of its lifecycle. Pallets can also be popular for DIY projects, including building garden features and planters!
There is only one UK manufacturer of loft boards, a company based in Devon. We have been buying their products for years but they have been having production and supply problems since the beginning of 2021, which they blame on Brexit. We anticipate getting our next supply from them in July 2021 in the autumn. They are however supplying the major DIY stores, albeit in limited quantities. Or, you can use other boards, as described on www.loftzone.co.uk/blog/which-boards . Finally, some DIY stores have started getting some supplies of OSB loft boards in from Poland this year, so you may find that these are in stock albeit again often only in limited quantities.
Unless you are happy to wait, we recommend that you buy LoftZone StoreFloor kits from this website and source your loft boards separately.
We offer all our customers a full, no-quibble, refund for the value of any unused parts, so long as they are returned within 3 months of receipt.
You will need to send items back to our UK warehouse in Leicestershire (postcode LE9), details of which are provided with the goods when delivered. All refunds will be credited to your original form of payment. Please note that the outbound delivery charge is not refundable, except in the unlikely case that there was a fault with the product.
Please also be aware that customers need to pay the return delivery charge for any items sent back, unless there is a fault with the product. Although we charge a flat outbound delivery fee, the actual cost can be much higher, often as much as £50, especially if you order a kit with boards, which will need to go on to a pallet. If however you order items without boards, then these are mostly sent as parcels and are much cheaper to return, typically half the cost of a pallet, or less. Once the items leave our warehouse, the couriers will alas charge for both delivery and return, even if you cancel before the items arrive at your address. If you’re not sure whether LoftZone is right for you, why not buy a small kit without boards to try out, as the return postage charge for this is typically only £12.
All the prices shown on this website include UK Value Added Tax, at 20%. If you need a VAT receipt, please let us know in the comments box when you order.
If you are ordering from another European or EU country, including The Republic of Ireland, then contact us after you have made your purchase and we will refund you the 20% VAT.
