How doors and windows can help your home go green

 Heat is often lost through doors and windows. This can be caused by several problems, including inadequate insulation, poor sealing and inefficient glazing .
For every degree of heat lost, your central heating system has to work that little bit harder. This means higher bills, more carbon emissions and a house that feels more like a refrigerator than a home.
Is it worth suffering in silence? No.
Many of the issues caused by heat loss can be resolved by upgrading to modern, energy-efficient doors and windows . Here are just some of the options available from Calder.

Double and triple glazing 

Double- and triple-glazed windows are highly effective in limiting heat loss in a home.
They're made of multiple layers of glass with insulating spaces in between, which act as a barrier to heat transfer. The insulating layers trap warm air inside the house, preventing it from being sucked outside.

Many houses in the UK were built before the advent of double glazing. But with our cold winters, it's amazing how much difference they can make once installed. 
The benefits are threefold. Double- or triple-glazed windows reduce energy bills, increase thermal comfort and help reduce your carbon footprint. They make an excellent investment towards energy-efficient and eco-friendly living in the UK.

Composite Doors


Composite doors are designed with a classic timber appearance but are built to modern energy-efficiency standards. This means you don't need to compromise on style to achieve excellent insulation.

 They incorporate a solid timber core, complemented by a surrounding layer of materials such as uPVC , laminate or fibreglass.
The combination of solid timber and modern materials enhances the door's overall durability, density and strength, making it a robust and headache-free option for your home. You won't need to worry about warping, creaking or leaking as you would with other traditional front doors.
Choose a composite door and you can rest easy knowing that your door is easy to maintain, looks great and is improving the energy efficiency of your home. Win-win-win!

Quick Fixes

Triple glazing and composite doors provide instant and impressive results. However, they take a fair bit of planning and a little investment.
In the meantime, why not consider these "quick fixes"? Both are simple and affordable ways to reduce heat loss and make your home more comfortable.

Draught excluders

Draught excluders have come a long way since the 1970s. It's not all about novelty sausage dogs and garish floral patterns anymore.

There are plenty of stylish and inexpensive options available nowadays, from door brushes to window wedges. You can even buy clip-on draught excluders that stay firmly in place even as you open and close the door.

Window dressings

Upgrading your curtains or blinds can help to trap heat and keep your home toasty and warm. Whether you opt for curtains, blinds or both, going made-to-measure can make all the difference. Made-to-measure blinds and curtains are designed to fit your windows perfectly, creating a snug and insulating barrier that helps to retain heat.
Choose your material wisely too. Thicker fabrics are good at retaining heat and reflective materials will create a thermal barrier, which helps to reflect heat back into your home.
