Casement Windows

One of our most pop­u­lar win­dow choic­es is our case­ment win­dows. These win­dows can be con­fig­ured in a num­ber of ways, with dif­fer­ent sta­t­ic and open­ing pan­els depend­ing on your needs.

Avail­able with alu­mini­um, uPVC or tim­ber frames, we can help with replace­ment case­ment win­dows on exist­ing prop­er­ties or brand new ones if you are build­ing a whole new home, or per­haps adding an exten­sion. All of our win­dows are made to order, so they’ll fit your home perfectly.

6 simple steps to new windows with Evander

Case­ment Win­dow Materials

Our Case­ment Win­dows come in three main mate­ri­als. uPVC, Tim­ber and Alu­mini­um. uPVC is strong, durable and requires very lit­tle main­te­nance. Alu­mini­um case­ment win­dows offer great longevi­ty and are extreme­ly tough. Tim­ber win­dows, although more expen­sive, cre­ate a tru­ly unique look and feel to your win­dows that you can only get with real timber.

Wheather you choose uPVC for a clas­sic fin­ish, alu­mini­um for cre­at­ing a stun­ning look for mod­ern homes, or tim­ber for a tru­ly unique and bespoke style, buy­ing your new Case­ment Win­dows from Evan­der guar­an­tees you strong, reli­able and beau­ti­ful win­dows for your entire home.

Our most pop­u­lar window

Case­ment win­dows are by far our biggest sell­ing win­dow style. This is due to their afford­abil­i­ty, mul­ti­ple size options and exten­sive range of fin­ish­es. This allows Case­ment win­dows to be cus­tomised to suit your needs, bud­get, home and lifestyle.

This lev­el of cus­tomi­sa­tion means you will always be able to cre­ate the exact win­dow for your home. Whether it be choos­ing the most pop­u­lar style — white uPVC win­dows with dou­ble glaz­ing and hinged on the side. Or maybe some­thing more bespoke like a tim­ber frame with triple glaz­ing and hinged from the top. The choic­es are endless.

Dou­ble and Triple Glazing

When replac­ing your win­dows or hav­ing new glaz­ing fit­ted, it’s impor­tant under­stand the dif­fer­ences between dou­ble and triple glaz­ing. They both have their own indi­vid­ual ben­e­fits, so a big fac­tor will be bud­get and indi­vid­ual pref­er­ence.


Dou­ble glaz­ing is two panes of glass in a sealed frame. Triple glaz­ing, as you can guess, is two panes of glass in a sealed frame with a third in the mid­dle. With the addi­tion of an extra pane, this does increase the cost, but the addi­tion­al price can bring a lot of extra ben­e­fits and the extra paid can soon become an investment.


Dou­ble glaz­ing offers great insu­la­tion to your home so it’s under­stand­able that triple glaz­ing offers even more. Reports have shown that upgrad­ing your win­dows from dou­ble glaz­ing to triple glaz­ing can reduce your annu­al ener­gy bill by up to 50%. This, of course, is assum­ing that the rest of your house is well insu­lat­ed too. There’s no ben­e­fit of hav­ing well-insu­lat­ed win­dows just for the heat retained to seep out an old, drafty front door.

The green­house effect”

Most home­own­ers will be famil­iar with this term. Most peo­ple feel they can con­trol the cold weath­er by get­ting bet­ter insu­la­tion, Where­as in sum­mer, typ­i­cal­ly south, south/​west fac­ing win­dows, can increase the room tem­per­a­ture to unbear­able levels.

This is where triple glaz­ing can help as it has a low­er G-Val­ue (low­er is bet­ter for glass, keeps you warm in win­ter and cool in sum­mer). Dou­ble glazing’s G-Val­ue is typ­i­cal­ly around 70% and triple glaz­ing is around 30%-50%.

Safe and Sound

Home secu­ri­ty is always a big con­cern. Two-thirds of all break in’s occur through the front door, back door or a ground floor win­dow. To have stur­dy and secure doors, only to have old ground floor, sin­gle glazed win­dows with rot­ten frames com­plete­ly removes that lev­el of secu­ri­ty. Remem­ber that bur­glars are oppor­tunis­tic and will always look for the eas­i­est point of entry.

Dou­ble glaz­ing cre­ates a stronger win­dow and triple glaz­ing only increas­es this strength as there are three panes instead of two. Also, triple glaz­ing is extreme­ly effec­tive for noise reduc­tion mak­ing this a must if you live on a busy street or near the main road.

Ener­gy effi­cient windows

Buy­ing a new door or new win­dows can be a daunt­ing expe­ri­ence and seem expen­sive. How­ev­er, when you start to realise how much mon­ey is wast­ed by poor ener­gy rat­ed win­dows, that expense soon turns into an invest­ment. Around 20 – 30% of the heat in your home is lost through windows.

Installing new, ener­gy effi­cient win­dows with dou­ble or triple glaz­ing will reduce this amount sig­nif­i­cant­ly, sav­ing you mon­ey and keep­ing the heat where it should be, in your home.
