uPVC Sliding Sash Windows Cornwall

Sliding Sash windows from Mike Martin Windows primarily function like a wooden box sash window with both the top and bottom sashes sliding up and down to suit your ventilation requirements but with the benefits of uPVC.

Their energy efficient frames combined with fantastic double glazing make them the favourite choice in period properties. Available in an extensive range of colours and finishes, it’s clear to see why people are making the switch from timber to uPVC.

Convenient and simple to operate, the two sliding sashes within an outer framework independently of each other on a balanced load mechanism, designed to hold the sash at any height.

Keeling, H

Superbly finished job

Replaced an outside wooden door with a UPVC one. Initial survey and advice was done very politely and efficiently. I was told demand might cause a wait. Received a phone call offering 8th Jan which I accepted. The fitter arrived on time, worked efficiently, tidied up and left us with a superbly finished job.
