Frequently Asked Questions

Choosing windows can be the most challenging part of your project. They can make or break your home! We've written 9 pointers that should help when you plan to change your windows!


Cost is a factor for any project and is no different when it comes to selecting the correct windows for you. uPVc is seen as the most cost-effective with aluminium being more expensive, with the most expensive being an alu-clad (composite of timber and aluminium).


If colour is a big factor for you and you want to stay away from a standard white frame, Aluminium and other high-end frames will come with the largest selection of colours.


Most frames come with several handle options to select from. Brushed-steel handles are most commonly selected as they match with almost anything!

Insulation values

Making sure you have the correct windows, to provide the best insulation for your house is critical. During those harsh winter months, it's important to make sure your house is insulated correctly so no heat can escape! The quality of windows insulation is done by the U-value, the lower the value the better the insulation!

Sash windows

Sash windows look great but can be complicated to fix and fit. Make sure you get a joiner with a good reputation to make sure you get the best finish for your property. Often made of timber, it's important they are replaced to fit the theme of your house.

Follow the rules

Make sure you follow the building regulations when selecting your windows. In Scotland, all windows "should have an unobstructed openable area that is at least 0.33m2 and at least 450mm high and 450mm wide. The route through the window may be at an angle rather than straight through and the bottom of the openable area should be no more than 1100mm above the floor." -

Decide on double or triple glazing

Decide on whether you want to have double or triple glazing. If you're aiming for an environmentally friendly house and want an A rating, you will need triple-glazed windows. These windows can be heavier and cost more. While double glazing is a viable alternative that provides a good heat barrier.

Opening direction

Make sure to factor in the opening direction of your window! This can often be overlooked. Your standard tilt and turn windows offer more flexibility as they can both open from the top and side however, curtains and blinds can get in the way. Bathrooms often use hung windows (top or bottom hinged) as it allows for better ventilation.


Most windows made today are equipped with a three or five-point locking system to provide the best security against lawbreakers, but be aware that both double and triple glazed windows can be easily smashed so make sure you keep any valuables out of sight!
