Danosa Glasdan 30 AP Elast | Sanded AVCL 1m x 7.5m

The Danosa Glasdan 30 AP Elast. is an SBS elastomeric AVCL (Air and Vapour Control Layer) with a weight of 3 kg/m². This sanded, torch-applied waterproofing bituminous sheet is designed for high performance and durability.

Overview: 

GLASDAN 30 AP ELAST. (7.5 m) is a waterproofing bituminous sheet with a non-self-protected surface, weighing 3.0 kg/m² (LBM-30-FV). It features a fibreglass reinforcement and is coated on both sides with SBS-modified bitumen mastic. The upper surface is finished with sand, and the lower surface is finished with a polyethylene film.

This product is ideal for high-performance waterproofing applications, providing long-lasting protection and adaptability to various construction needs.

Important details about this product:

• Length: 7.5m
• Width: 1m
• Thickness: 2.5mm
• Weight: 3 kg/m²
• Surface area: 7.5m²

Advantages & Benefits

• Minimal Thermal Variation – Exhibits little thermal variation, maintaining stability under different temperature conditions.
• High Dimensional Stability – Ensures consistent performance without significant deformation.
• Enhanced Bitumen Performance – The SBS-modified bitumen mastic significantly improves performance compared to other bituminous mastics, offering better elasticity, temperature reaction, and ageing resistance.
• Durability and Safety – Increased durability and safety of the waterproofing membrane due to enhanced material properties.
• Deformation and Stress Limitation – Effectively limits deformations and stresses in the waterproofing membrane.
• Excellent Multilayer Performance – Provides superior performance in multilayer systems with hot asphalt.
• Versatile Adaptability – Can adapt to any type of geometry, ensuring versatility in application.
• Compatibility with Molten Asphalt – Suitable for working with molten asphalt, enhancing its application range.

Substrate preparation: 

• The base support surface must be durable, uniform, smooth, be clean, dry and free from foreign bodies. If thermal insulation defines the substrate, insulation boards should be installed fully adhered to the basis with DANOTHERM, without bigger separation than 1mm between insulation boards.
• Before laying the waterproofing membrane, DANOBOND adhesive must be used in the whole susbrate surface or insulation boards. The membrane should climb on the vertical face a minimum of 20 cm above the surface of the pavement. Any joint between metal profiles and the vertical surface, will be always sealed with elastic sealant ELASTYDAN PU 40 gris.

Waterproofing layer placement:

• The membrane will be placed fully adhered over the support or the insulation board, installed perpendicular to the roof maximum slope line, from the lowest point to the top of the roof. The watertightness between DANOPOL membranes will be achieved through thermoplastic welding with hot air welder, or using chemical agent THF (tetrahydrofuran).
• The overlaps between membranes must be 5cm minimum and the welding must be at least 4cm. During the thermoplastic welding, use a silicon pressure roll.
• After the installation, it is recommendable to use a blunt metal needle (with a 1-3mm head radius), passing it along the union edge, verifying all the connections. There should not be more than 3 membranes coinciding in a single point. Special attention will be paid to T-Joints (three sheets intersecting at the same point).
• All membrane vertexes will be cut in a curve shape.
• To perform transversal membrane overlaps, or if any metal profile is intended to be set on the waterproofing membrane, they will be covered by welded 21cm DANOPOL HS 1.5 COVERSTRIP, with the same color.

Do you offer Free Delivery?

Yes! On most insulation orders over £400 excluding VAT, we can offer free delivery*. 

Delivery depends on stock availability and location. If stock is not available at your local branch and must be delivered from another branch, this may affect lead time or delivery charges. In this case, one of our advisors will contact you to confirm any changes.

Where will you deliver my order to?

All deliveries are kerbside only. It is your responsibility to move items from the kerb onto your property. The courier decides where the order is left, so please ensure there is ample space to offload.

Delivery access and site restrictions

These items are typically delivered on large 18T or 26T rigid lorries, approximately 10–12 meters long, 4 meters high, 2.6 meters wide, carrying 12–14 pallets.

Please inform us of any access restrictions or site issues in advance; failure to do so may result in extra delivery charges.

When do you dispatch orders?

If your order is placed before 12:00 PM, we aim to process and dispatch it on our lorries the next working day. Occasionally, lorries may be full, or stock may need to be brought in from another branch, which can extend delivery up to 10 working days. Some areas are subject to set delivery days due to distance from the local branch.

Please ensure to leave a mobile number so that we can contact you with your delivery date once we have received confirmation from the local branch. This also allows ourselves or the delivery driver to contact you if there are any issues with your delivery.

Why do we need your contact number?

It is essential to provide a mobile number so we or the delivery driver can contact you if there are any issues. For orders of this nature, we may contact you after ordering online to discuss delivery options, site restrictions, or offloading requirements.
