Made to Measure Loft Hatch – Insulated & Air Tested
Product details
Made to your opening, to the millimetre
A loft hatch is the weakest point in an insulated ceiling. A standard hatch dropped into a non-standard opening leaves a gap, and that gap carries warm air into the loft for the life of the building. This one is made to the size you give us, so there is nothing to pack out and nothing to make good.
Maximum size 1100 × 950mm. Handmade in the UK.
Specification
- Insulation — 50mm mineral wool. U-value 0.32 W/m²K.
- Airtightness — tested at 0.23 m³/m/hr at 50 Pa [insert test report ref].
- Door and frame — 1mm Zintec steel, powder coated in 20% white gloss (RAL 9010).
- Ceiling protrusion — 7mm. Hinges and fixings are concealed.
- Depth above the ceiling — 63mm standard; 30mm where either dimension is under 450mm.
- Weight — approximately 6-12kg.
- Insulation environmental data — zero GWP, CFC and HCFC free.
Both lock types run a cam that pulls the door onto the seal as it closes, which is what the airtightness figure depends on.
How to measure
Measure the distance between your ceiling joists in millimetres and deduct 5mm. That is the size to order. The 5mm takes up the out-of-square you get in almost every opening.
The outer frame then sits on the ceiling and adds 25mm on every side, or 50mm if you choose the wider frame option. All four sides are the same width — the frame cannot be made wider on one side than another.
Locks
- Tri-Drive — the standard fitting. An O-ring seal at the lock gives the tightest closure, and the opening pole is supplied free.
- Key lockable — for lofts that need to be secured. The opening pole cannot be used with this lock.
If the hinge side is longer than 750mm, specify two locks. A single lock on a long door leaves the far corner of the seal under less pressure than the rest.
Options
- 50mm frame — a wider face, useful where the ceiling around the opening is damaged or where you want more cover over an untidy edge.
- Silver insulation cover — a faced cover over the mineral wool. Supplied uncovered as standard.
- Second lock — see above.
Fitting
Fixings and step-by-step instructions are in the box. The frame screws into the surrounding timber.
The door sits slightly proud on the lock side when new. That is the seal under compression, and it settles back over the first few months.
Delivery and returns
Made to order, in the lead time shown above, free delivery to most UK mainland postcodes. Lead times are working days and exclude weekends and bank holidays.
This hatch is made to your dimensions and cannot be returned.
Is this fire rated?
No. The SDS is an insulated, air-tested hatch and carries no fire rating. If the ceiling forms part of a compartment — a loft conversion, a flat, anything where building control is looking at compartmentation — you need a rated hatch instead. We make those to size as well: SDS-FR, 1 hour, up to 900 × 600mm, and SDS-FR-OS-90, 90 minutes, up to 900 × 900mm.

Ordered hatch on Monday and promised by following Monday/Tuesday. Hatch was duly delivered the following Tuesday and is exactly as described. Really makes a difference in our hall when we replaced the old painted plywood hatch. First class product and service.

Needed a new loft hatch to replace the piece of wood we had. Although we had an odd shaped opening so ordered bespoke. Was very happy when it arrived and fitted perfectly As someone else said, I think the lock mechanism could be rethought with the insulation but its a minor point.

I have ordered this hatch twice and have not been disappointed yet. They are well made and well packaged. I would recommend fitting as a two person job but it can be done alone as I have to do. The only area I feel could be improved is around the locking mechanism as it tears the foil cover. Still its a great product and I would definitely recommend.

This is the third loft hatch I’ve bought / installed & I have to say, as long as you measure correctly they are so easy to fit. The quality of the hatch is excellent. The ordering process is relatively easy & delivery for a made to measure is pretty prompt. All in all I would thoroughly recommend Jupiterblue.

Very efficient service and very good product. Due to design of product, even though it should be a 2 person fitting, I was able to fit myself which was another plus. Fitted extremely well, far superior to original hatch from original build.
-
Excellent hatch, especially with the silver cover. Nice low profile giving a very clean, smart and unobtrusive finish. Excellent service as always, thanks! :)

I made my loft hatch hole bigger 12 years ago so I good put a loft ladder in. I made a DIY loft hatch cover which was OK but not airtight/insulated. Roll on the years and I had the ceiling skimmed to improve the look and then my DIY loft hatch looked rubbish. Ehmm? how to get a loft hatch cover to fit my odd sized hole? Eureka found this one made to measure. Bit of a juggle getting the first screws in place to secure it but after that it was very easy and it looks and works beautifully. That's it ceiling skimmed, loft hatch secured and all looks fab. Back to the kitchen floor now.
