Heavily insulated loft hatch with 3-section folding timber loft ladder.

The LEX 70 combines Swedish quality with first class design and functionality that meet high elegance and stability requirements. The compact loft ladder is manufactured of slow grown spruce and is known around the world for its strong design and durability. In the closed position, it does not take up space in the loft. Hatches are available in two sizes: 540mm x 1130mm and an extra wide 700mm x 1130mm.

The LEX 70 is supplied with a cellular plastic insulated hatch which complies with European standards by effectively keeping heat in and draughts out. Its U-value of just 0.40 makes it arguably the most energy efficient ladder system available.
