The SDNL is a loft hatch with an inset window to allow natural light through the loft door from the loft space via skylights, windows or clear tiles in the roof. The door is insulated and fully bonded with a 25mm five layered opaque polycarbonate sheet giving a "U" value of 1.6 (please note this product is not fire rated and has a ribbed effect).
The SDNL is a "Made to Measure" option with a hinge down steel loft hatch for an unobtrusive, contemporary design. There are no projecting hinges or handles, just simple clean lines.
The loft access door requires no painting and projects into the ceiling space a mere 8mm.
Our unique "Made to Measure" SDNL loft hatch has an innovative concealed hinge and a flush lid, contributing towards its unobtrusive look.
The loft hatch has a neat tri-drive budget lock with a built in chamfer for a smooth closing action and high compression.
In addition to the draught seal between the frame and lid, the SDNL loft hatch has an extra concealed draught seal between the frame and ceiling. This virtually eliminates warm air leakage and vapour ingress, it also makes for easy decoration up to the edge of the frame.
The loft hatch frame and lid are white colour RAL No. 9010 with 20% gloss.
When ordering the loft hatch, we would recommend measuring the ceiling cut out (trim size) and deducting 5mm, in case the joists and noggins are not perfectly square. In addition the loft hatch will be hinged on the short side unless stated otherwise.
The largest size we can produce at this price is 900x900mm. If you require a hatch bigger than 900x900mm please contact us on 01937 325 325 for a quote.
This hatch has a nice finish but beware of scratching the plastic window - very easily done. Would have benefitted from a protective film for installation. Also, polystyrene from packaging got inside window and was very hard to remove.
Installation is unquestionably a two person job but fairly simple.
Hatch is quite deep so doesn't swing completely clear below opening. Had to bring forward ladder hinge point to avoid hitting back edge of open hatch.
Really nice finish to metal surface and lock. Window is very clear and let's in a lot of light. Can see features in loft.
Supplied pole is way too short. I drilled out the rivet holding the hatch key and refitted onto longer pole supplied with my ladder.
Took about 3 weeks to arrive (included Easter holiday).
2nd hatch I have purchased from Jupiter... this one has window for natural light. Fitted last night , job complete in 15 minutes.. very happy with quality , and service / delivery excellent also. I would recommend Jupiter to anyone.
