The influence of artificial ageing on bonded heat-treated spruce lamellas was investigated. Heat-treated spruce lamellas with different degrees of thermal modification were bonded with PVAc and MUF and then exposed to 500 artificial weathering cycles, combined with rain, UV and IR radiation. The colour change of the exposed surface, weight change, delamination of the bonded joints and adhesive bond strength were measured. Artificial weathering caused cracking and delamination of the bonded joints and reduced the bond strength of both adhesives. The results show that delamination was higher for PVAc adhesive than MUF, but increased for both adhesives with the temperature of heat treatment of wood. The shear strength of bonds on the exposed side of the samples after the artificial weathering was lower than the average strength of the whole sample. U radu je istražen utjecaj umjetnog starenja na lijepljene lamele toplinski modificirane smrekovine. Lamele toplinski modificirane smrekovine različitih stupnjeva toplinske modifikacije lijepljene su PVAc i MUF ljepilom, a zatim su tijekom 500 ciklusa izložene vremenskim utjecajima u kombinaciji kiše te UV i IR zračenja. Mjerena je promjena boje izložene površine, promjena mase te delaminacija i čvrstoća lijepljenog spoja. Umjetno izlaganje vremenskim utjecajima uzrokovalo je pucanje i delaminaciju lijepljenih spojeva te smanjenje čvrstoće spoja lijepljenog obama ljepilima. Rezultati pokazuju da je delaminacija bila veća na slojevima s PVAc ljepilom nego na slojevima lijepljenim MUF ljepilom, ali je povećana na slojevima s oba ljepila, uz povećanje temperature toplinske modifikacije drva. Nakon umjetnog izlaganja vremenskim utjecajima smična je čvrstoća lijepljenog spoja na izloženoj strani uzoraka bila niža od prosječne čvrstoće cijelog uzorka.
