Sash Window Upgrades (FAQs)

Frequently Asked Questions

The sash window upgrade is our flagship product. The following list of questions and answers will provide you with an understanding of the product and the process.

Q.  What is a sash window upgrade?

A.  We manufacture new wooden sashes and fit them with Planitherm Total glazed units.  The new sashes are designed to fit into your existing window frame.  This makes a considerable improvement to the window’s thermal and acoustic properties.

Q.  Can my existing window frame be replaced during the upgrade process?

A.  Yes, we can manufacture and fit a new window frame, if you want us to do so.  However, we normally only replace frames when it is necessary to do so.  You can rest assured that your existing window frame will be thoroughly checked and repaired, as is appropriate.

Q.  Do upgraded sash windows look like traditional sash windows?

A.  Yes, we replace the glazing bar positions in order to ensure the window’s traditional look and style is maintained.

Q.  What type of wood do you use when manufacturing new sashes?

A.  We use Accoya® because it has outstanding durability and is guaranteed for 50 years when used above ground.  Please take time to watch the Accoya video on our website.  It explains why the timber has such long-lasting qualities.

Q.  Will the existing sash weights be sufficient to counterbalance the Planitherm Total glazed units?

A.  No, upgraded sash windows are much heavier.  We usually fit spiral balances to counterbalance the additional weight.  However, we can fit heavier lead weights if a customer prefers to retain the traditional mechanism.

Q.  Are upgraded sash windows fitted with draught excluders?

A.  Yes, we fit draught excluding staff and parting beads as standard.

Q.  Do you paint your sash windows?

A.  Yes, we have a spray-painting facility at our workshop.  So, you can have your new sash windows finished in any (RAL) colour you choose.

Q.  Do you use external contractors to fit your upgraded sash windows?

A.  No, we use our own staff.  Our approach to quality is based on us controlling the process from start to finish.
