RoofLITE+ SLIM VENT Roof Window Bundle – Roof Window & Slate Flashing

RoofLITE+ SLIM VENT Roof Window Bundles allow you to purchase a roof window and a flashing kit in just a few simple clicks.

Available in a variety of sizes, this window bundle offers a RoofLITE+ SLIM VENT and a RoofLITE+ LSX Slate Flashing,

Purchasing a window bundle will save you time whilst benefitting from the amazing prices you come to expect with the range.

The SLIM VENT is the standard pine, centre pivot option with a ventilation valve that allows you to ventilate your home, without having to open your window at all.

Not only will you benefit from fresh air, whether it be through the ventilation valve or opening your window, you will also benefit from a flow of natural daylight into your home.

The mechanism is located at half window height ensuring easy operation which is aided with ergonomic handle, which can be found at the very bottom of the sash.

The handle has a number of locking positions, which you can use to further ventilate your home without having to fully open your window, whilst remaining secure.

The SLIM VENT includes a slimmer frame in comparison to the SOLID WHITE and SOLID PVC and is manufactured from sustainably sourced pine wood.

The pine wood has undergone an impregnation process during production, which ensures durability and robustness over years.

Despite its slim frame, the SLIM VENT has a u-value of 1.3 W/m²K, which is comparable to most other windows in the market.

It is also comparable to its white frame counterparts, the SOLID WHITE and SOLID PVC, as both of these windows have the same u-value.

The roof window bundle combines the SLIM VENT with a LSX Slate Flashing, which offers a 10 year guarantee.

The LSX Slate Flashing is compatible with all slates with profile thicknesses up to 8 mm and allows installation into roof pitches between 15 and 90 degrees.
