Installation FAQ's

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 will be need to be made of wood and be at least 32mm (1.25″) wide and 75mm (3″) tall.

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. Please contact us for details on pricing (shipping is more expensive alas). 

If you are still unsure whether your property is suitable, please contact us on or 01483 600304 and we’ll be happy to advise you.

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.

If you’re unsure what you need, then please contact us on or 01483 600304 with your measurements and we will work it out for you.


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 our kits and, if you buy the boards from us too, we supply enough for the boards, too. 

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.

Strength & Safety

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 or LABC. If StoreFloor was fitted by your builder as a paid-for option, then it will be covered under this warranty, because the warranty typically covers the materials and the labour of the items fitted by the builder. But if it was not fitted by your builder, then it won’t be covered by the warranty for the house. Neither will it 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. You can also download our BBA Certificate (which is required for all building products for new build houses) via this page

Of course, you need to be sensible. If 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 the product 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. 

Order & Delivery

Orders will normally be delivered in 2-4 working days, and always within one week. 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 UPS. Both Palletways and UPS are quality, reputable, companies and the vast majority of shipments are delivered rapidly and without any problems. 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,

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. 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. 

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.

All StoreFloor kits and loft ladders are shipped at a flat rate within the UK of £12 (Monday-Friday) or £25 (for the rest of Europe), regardless of how many items 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.

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,

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 recycling company.  They 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!

Refund Policy

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. 

If you would like to return anything, then please contact us on 01483 600304 or and we will provide you with a return form to be completed and sent back with your items.  

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.
