Draught seals

Our sash windows are all draught sealed as standard. We use a sealing method unique to us that has a dual purpose. Firstly it does what it says, and keeps out draughts with a combination of vertical brush pile seals and compression seals on the horizontal rails. Secondly, by positioning the vertical brush piles to run between the sash and the pulley stile, this makes the sliding action smooth, by eliminating the all too common side to side judder . And thirdly, our brush piles are not visible in either the open or closed position. Subtle but noticeable differences.

 Factory finishing

The main function of a paint finish is to protect the timber from becoming wet, since wet is it worst enemy. Traditionally, paint is applied by brush, after the windows have been installed.

Factory finishing uses specially formulated coatings which are spray applied, prior to glazing.

Among the most susceptible areas in timber windows and doors, are the undersides of bottom rails, where the endgrain of the stiles is exposed. Water often remains held here long after it has stopped raining. Unfortunately, these areas are difficult to reach by brush, and easily overlooked during in-situ painting. To make matters worse, the porous nature of timber endgrain, requires more paint coverage here, than any other area.

Benefits of factory finishing:

• Latest generation Sikkens microporous finishes mean that no further painting is required for up to 8 years.
• Highly flexible coatings allow for the inherent slight timber movements, that crack poor quality finishes.
• Bottom rails receive more paint than all other surfaces and are completely sealed.
• Applied in a controlled environment, it eliminates the risk of the windows getting wet prior to decoration.
• Eliminates the disruption caused by having to leave windows open while each brush coat dries.
• Not dependant on weather for decorating.
• Makes the sliding action of our sash windows effortlessly silky. ( Avoids common 'paint stuck' sashes)
• Achieves a neatness of finish that cannot be matched by brush painting.
• Reaches areas that become inaccessible after installation. ( glazing rebates, backs of sash stiles etc. )

Glazing Rebates.

We place the glazing rebate and glazing beads on the internal face. This protects the susceptible beads from allowing water to penetrate the rebate, the prime cause for glazing unit failure. By placing the rebate internally, the exterior weathering face is one completely seamless face without breaks. You'll start to see why its superior in a year or two of British weather.

Glazing bars

Whilst glazing bars are specified for purely aesthetic reasons , they nevertheless have quite a profound impact on the look of a window. Glazing bars for single glass are traditionally very narrow, giving the window an elegant look. Double glazing however, requires much thicker bars to accommodate the deep glazing rebates. Where thick glazing bars would look out of keeping, it is standard practice to use ‘applied’ glazing bars. These are bonded on to both faces of the glazing unit, to give the same appearance as a narrow bar for single glazing.
Our system of applied bar is a bit more considered than most. Take a look.

Radius edges


The surface tension in most liquids, including wet paint, causes them to physically pull away from sharp edges. This results in a thin paint coverage on the edge. This same surface tension is enough to keep rainwater pooled along any sharp horizontal edges such as sloping sills, even against the pull of gravity. Right at the place where the paint is thinnest and most vulnerable. The result is a shortened lifespan of both the paint coating and the window.
We machine a radius on all the exposed edges of our windows. No surface tension. No thin paint edges. No pooling water. Years added the life of the window.
