More Information on Thermal Lining

Thermal curtains are specially designed curtains that help regulate the temperature of a room by reducing heat loss in winter and blocking out excess heat in summer. If you're a buyer considering purchasing thermal curtains, here's what you need to know:

GTOT (G-value) and Solar Gain:

When purchasing thermal curtains, it's important to look for curtains with a low GTOT (G-value). GTOT or solar gain is the amount of heat that passes through a window into a room. The lower the GTOT, the less heat will enter the room, resulting in cooler temperatures in the summer. In winter, you want curtains with a high GTOT value to allow more heat to enter the room, which helps keep the room warm.

Thermal Insulation of Direct Fabrics Curtain Lining:

Direct Fabrics Curtain Lining is a 3 pass blackout lining that provides a 30 percent reduction in heat loss through windows. This means that the lining helps to retain heat in the room, reducing the amount of energy needed to heat the room. This lining is especially useful in colder climates, where it can significantly reduce energy bills and help keep homes warm.

In summary, when purchasing thermal curtains, pay attention to the GTOT (G-value) and choose curtains with a low GTOT for summer and high GTOT for winter. Additionally, consider Direct Fabrics Curtain Lining to provide extra thermal insulation and help reduce heat loss through windows. With these factors in mind, you can choose the perfect thermal curtains to keep your home comfortable all year round while saving on energy costs.

Why Choose Direct Fabrics Thermal Lining

Direct Fabrics 3 Pass Lining is designed to provide both thermal insulation and light-blocking capabilities to curtains. The ivory color of the lining gives it a low GTOT, making it effective at reflecting sunlight and preventing excess heat from entering the room during the summer months. Meanwhile, the thickness of the lining helps to retain heat in the room during the winter, reducing heat loss through the windows and keeping the room warm.

To keep a room cool in summer with thermal curtains, it's important to close the curtains during the hottest part of the day, typically midday to late afternoon. This will prevent excess heat from entering the room and keep the room cooler. Choosing curtains with a low GTOT, such as those with Direct Fabrics 3 Pass Lining, will also help to reflect sunlight and prevent heat from entering the room.

To keep a room warm in winter with thermal curtains, close the curtains at night to prevent heat from escaping through the windows. Choosing curtains with a high GTOT, such as those without a lining or with a thin lining, will also help to allow more heat to enter the room through the windows.

how to measure for curtains

Choosing your Curtain Track Width

The width of the curtain track should extend past your window this allows for the curtains to stack back away from your window and allow light in.

Measure your recess and then add on 15cm on either side. For acoustics , we recommend further to fully cover the window and the surrounding area. In our test we added an additional 30cm to the width and also made the curtain floor length.

Wave curtains, for every 100cm of track the curtains will stack circa *18cm

Eyelet curtains, they will stack back circa 10cm per *70cm of track width

Pencil Pleat will stack approx 25% of the track width. eg. 210cm track will stack 52.5%

* all dependent on thickness of fabric

How to Measure for Blinds going Inside the Recess

How to measure for blinds inside thet recess

  • Measure the exact width of the recess in three places; at the top of the recess, in the centre of the recess and near the bottom - then take the  smallest size.
  • Measure the exact drop of the recess in three places on the left hand side of the recess, in the centre of the recess and on the right hand side of the recess - then take the smallest size.
  • We will take one cm off the finished width size you have given us, to allow for the blind to pull up and down easily.
  • Double check your measurements
  • Cord Safety - Mounting Height - We ask for the mounting height of your blinds to allow for the cord to be 150cm off the ground. If mounting at 210cm This is what you enter in the Fitting height box. We make a deduction to ensure the cord is 150cm from the floor. Thus the cord loop will be 60cm

How to Measure Outside of the Recess

  • Measure the recess in 3 places on the width and also 3 places on the drop. Take the widest measurement.
  • Measure the width of the actual recess plus an additional amount – Usually from 7cm-15cm whatever you think looks appropriate. This is for overlap.
  • Measure the exact drop of the recess. The blind would be fitted above the recess, so check the space above and add an amount on to the drop – usually from 7-15cm
  • These sizes you have taken will be the size of the finished blind.

  • Double check your measurements
  • Cord Safety - Mounting Height - We ask for the mounting height of your blinds to allow for the cord to be 150cm off the ground. If mounting at 210cm This is what you enter in the fitting height box. We make a deduction to ensure the cord is 150cm from the floor. Thus the cord loop will be 60cm

Cubicle Tracks you have to measure with right angles from wall to wall where you want the track to go

Draw your room on a piece of paper with a sky view

Now measure from the wall to wall for straight tracks,

L Shape Tracks Measure to a point on the floor and mark with a piece of tape. Then for the other sides measure from the other wall to that point.

Always check for obstructions and fitting issues you may need to work around
