Rain protection for the balcony without drilling
what fabric can and cannot do
If you are looking for rain protection for a balcony without drilling, you quickly end up with fabric: a cloth, curtain or sail. To be honest, though, textile sun and privacy protection is not a rain roof. A good outdoor fabric is water-repellent and lets rain run off, but it is not waterproof. Here you can read what fabric does in the rain, where its limit lies and what still helps on an open balcony without a drill hole.
Rain protection for an open balcony that is waterproof and holds without drilling cannot be built from fabric. This list sums up what fabric can do:
- Vertical, rain runs off at once: a balcony cloth or curtain made of water-repellent Agora lets the water run down the surface.
- Sloped, rain only runs off from a slope of 25 to 30 cm per metre. Tensioned flatter, water collects in the fabric.
- A roof made of fabric is not a storm or rain roof: the rope tension awning and rope tension shade sail are pure sun protection and are retracted in rain, strong wind and storms.
- Water-repellent does not mean waterproof: in persistent or heavy rain, moisture can get through the fabric.
What fabric can and cannot do in the rain
Outdoor fabrics for sun and privacy protection are made for outdoors and can take getting wet. Whether rain runs off or stays put is decided mainly by the position of the surface.
Water-repellent
Agora is water-repellent: rain beads off and runs down the surface. Agora Liso has a rating of 180 mm water column. How water-repellent and waterproof differ is explained in Leave an awning out in the rain?
Vertical, water runs off
If the fabric hangs vertically, like a balcony cloth on the railing or a curtain, the water runs off at once. At the side, fabric is therefore a usable protection against rain blown in by the wind.
Slope 25 to 30 cm per metre
A sloped surface lets rain run off from a slope of 25 to 30 cm per metre. If the slope is too slight, pockets of water form that strain the fabric and fixing.
Not waterproof
In persistent or heavy rain, moisture can get through a water-repellent fabric. Fabric does not replace a solid roof over the balcony.
Wet becomes heavy
A large curtain soaks up water in persistent rain and becomes heavy as a result. The suspension and the construction behind it must carry that. After the rain, the fabric dries quickly again.
Colour stays
Agora is solution-dyed and can take sun and rain in turn. It has a 5-year warranty on colour fastness.
What remains on an open balcony without drilling
With no ceiling over the balcony and no drill hole, three options remain: protect from the side, cover the furniture and take the fabric down in bad weather. What else there is without drilling is shown in the guide Sun protection on a balcony without drilling.
Balcony cloth on the railing
The balcony cloth has stainless steel eyelets in the hem and holds on the railing with cable ties or cord, with no drilling at all. It is opaque and protects the area behind the railing from wind and side-on rain. How to fit it is explained in fixing a privacy screen to the balcony railing.
Cover the furniture
Against rain from above on an open balcony, a cover over the table, chairs and cushions protects, with more at protecting garden furniture.
Retract in rain
You slide the rope tension awning and rope tension shade sail together in rain, strong wind and storms. You take a balcony cloth down before winter or before a storm, and cord is easy to untie for that.
Curtain instead of cloth
An outdoor curtain hangs from a wire rope or track, and both are screwed in. What options there are without drilling is explained in curtain on a balcony without drilling.
Ask the landlord
If you rent, ask the landlord before any fixing to the façade or railing, preferably in writing. That also applies to a cloth that holds with cable ties only.
Where fabric reaches its limit on a balcony
Textile sun and privacy protection is not a storm or rain roof. An awning, a shade sail or a pergola with a fabric covering give shade, but they do not offer dense rain protection.
In strong wind and storms, fabric should be retracted or taken down, because wind tugs at every tensioned surface and its fixing. What applies in wind and in winter is explained in ideas for wind protection on the patio.
If you tension a sail horizontally over the balcony, you get a pocket of water in rain. Shade from above needs a slope and load-bearing fixing points.
Shade, privacy and fabric for the balcony
Rain is usually only one of several questions on a balcony. These pages lead on, and you will find all topics around sun protection in the sun protection guide.
