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.
Reviews

Being able to order custom dimensions helped greatly as our hatch aperture was irregularly sized. Savings were made avoiding joinery / restructuring. The product itself was well made, affordable and came in good time despite custom manufacture. Installation was possible easily with two people. Hopeful that it'll reduce airflow between living space and loft as intended (a significant insulation / heat loss / condensation issue).

I've received my bespoke attic hatch and have to say I'm most impressed with the build quality. Whilst not cheap (compared with a plastic one) it it well worth the outlay. I'm impressed with the 'tight' manufacturing tolerances, welded corners and overall finish. I would strongly advise you to include a 'Made in Great Britain' label on the inside face. You should be proud to produce quality like this. It makes a fantastic change not to have something made in China for a change!!! 10/10 Excellent product

Excellent product, very easy to fit. Easy to use and looks good

Obtained two of these hatches, one for our house and one for our daughter's. The quality and finish is good, and they were straightforward to fit. The 760mm length makes it easier to get in and out of the loft, and it was straightforward to cut the plasterboard a little and refit the wood cross pieces, to accommodate it being longer than the old hatch. Worth doing if you have a smaller opening currently. At the \reduced\ price they are good value.

This is a good quality product. It arrived on time but unfortunately the corner was damaged. The company replaced the product without any trouble. The only criticism was that the delivery time is so long, but this is a bespoke made product. It is just disappointing when the replacement delivery time as added. I would buy this product again for this company if I needed another.

I had to buy bespoke because the size of my existing opening could not be replaced by any cheaper off the shelf types available. Took care to make sure my measurements were correct, and when delivered it slotted into my wooden frame perfectly, I had one small problem, when I tried to close the Hatch the tongue of the catch was too long to slot fully home and was hitting my wooden frame, meaning only a corner of the tongue was holding the cover in place. Not being happy leaving it like this I chiseled a small slot in the timber allowing the tongue to turn fully home, I assume the catch was inserted too close to the edge of the cover. I am really happy with the end result, I now have a dust, draught and insulated Hatch that looks really good on the ceiling. A quality product that was easy to install.
